Definitions
- the present invention relates to an assembly of a drive pulley with the rotor of a rotary electric machine equipping a motor vehicle.
- the invention relates in particular to an assembly of a motor vehicle alternator pulley.
- the pulley allows the rotor of the alternator to be rotated using a drive belt.
- the invention relates more particularly to an assembly of an alternator pulley, of a motor vehicle, devoid of a decoupling device of the "freewheel" type, such a device allowing the transmission of torque only in one direction of rotation.
- assemblies of the type are known in which the pulley comprises a peripheral functional zone intended to cooperate with a belt and a central hub comprising an axial hole for the passage of the rotor shaft.
- the central hub of the pulley is mounted free at the end of the shaft, that is to say that the latter has a smooth section which crosses a section complementary to the axial hole of the pulley hub, and the central hub is clamped or pinched axially between the inner ring of a rotating guide bearing of the rotor shaft and a clamping nut which is mounted screwed on a threaded section free end of the rotor shaft.
- a washer can be interposed axially between the pulley and the nut and the value of the torque resisting the sliding of the pulley on the shaft results from the value of the tightening torque of the nut.
- this torque is limited by the resistance of the materials, to compression or elongation, of the various components of the assembly, as well as to the surface conditions of the parts of the components in mutual contact.
- Such loosening can also occur in the event of acyclisms of the torque to be transmitted resulting from the operation of the combustion engine.
- the pulleys provided with freewheeling devices are much less sensitive to these loosening phenomena by virtue of their constitution which allows the transmission of the rotary torque than in one direction.
- the alternator makes it possible to transform a rotational movement of the induction rotor, driven by the vehicle's heat engine, into an electric current induced in the stator windings.
- the alternator can also be reversible and constitute an electric motor; its stator then constituting an inductor and its rotor an armature allowing the combustion engine of the vehicle to rotate, via the rotor shaft.
- This reversible alternator is called an alternator-starter and allows mechanical energy to be transformed into electrical energy and vice versa.
- an alternator-starter can start the engine of the motor vehicle, constitute an auxiliary motor to drive for example an air conditioning compressor or even operate in engine mode to drive the motor vehicle.
- the stator has three windings so that the alternator is of the three-phase type.
- the alternator is of the hexaphase type and can be wound with conductor bars forming pins.
- the invention proposes an assembly of a drive pulley with the rotor of a rotating electric machine for a motor vehicle, in particular an alternator or an alternator-starter, comprising on the one hand , a shaft carrying a rotor and a front ball bearing and, on the other hand, a pulley comprising a peripheral functional zone intended to cooperate with a belt and a central hub comprising an axial hole for the passage of the rotor shaft in which the pulley has an internal grooved section for its press fit on external grooved section complementary to the rotor shaft.
- the maximum torque which can be transmitted by the assembly is no longer dependent on the axial clamping of the pulley, that is to say the tightening torque of the nut according to the state of the art.
- the invention also provides a method for mounting the assembly described above in which, starting from a pulley provided with a front transverse bottom, an annular extension of axial orientation comprising a transverse shoulder and a recess front center, - a threaded rod is screwed into a threaded hole in the rotor shaft
- a spacer is mounted, with internal bore and a rear tubular end, in a central front recess of the pulley, a rear face of the rear tubular end of the spacer coming into abutment against the front transverse bottom of the pulley, while that the threaded rod passes freely inside the bore of the spacer.
- - Figure 1 is a partial axial sectional view of an alternator according to the state of the art.
- - Figure 2 is an axial view of an alternator rotor shaft according to the invention.
- - Figure 3 is an axial view of an alternator pulley according to the invention.
- - Figure 4 is an axial view of an alternator pulley mounted on the rotor shaft according to the invention.
- FIG. 5a, 5b and 5c are views describing the method of mounting the pulley on the rotor shaft according to the invention.
- FIG. 6 is an alternative embodiment of the invention of Figure 2.
- FIG. 7 is a view perpendicular to the axis X-X of an alternator rotor shaft according to the invention.
- FIG. 8 is a view perpendicular to the axis X-X of an alternator pulley according to the invention.
- FIG. 1 shows a polyphase alternator, here three phase, for a motor vehicle mainly consisting of a casing 12 in two parts 15, 17 connected to the mass of the motor vehicle and internally carrying two main members which are a stator 14 and a rotor 16 as described for example in document EP B 0 515 259 to which reference will be made for more details.
- the parts 15, 17 therefore have tabs for their attachment to a fixed part of the vehicle.
- the stator 14 surrounds the rotor 16, which is integral with a shaft
- the stator 14 is composed of a body 22 which here consists mainly of an axial stack of transverse sheets of soft iron.
- the inner annular face of the body 22 has axial grooves, which extend radially outward and which receive axial strands of electrical windings 32.
- the grooves are open inward as visible for example in document FR A 2 603,429.
- Each electric coil 32 is for example constituted by the winding in turns of an electrically conductive element, here a copper wire, which is coated with at least one layer of electrically insulating material, for example a polyester in two layers one of the polyimide type, the other of the polyamide imide type.
- the axial strands are extended by transverse junction strands which form buns (not referenced) projecting on either side of the body 22 of the stator 14, in accordance with FIG. 1.
- conductors in the form of bars, such as pins, of circular or rectangular section mounted in the axial grooves of the stator 14 as described in document WO-92/06527.
- conductors in the form of bars, such as pins, of circular or rectangular section mounted in the axial grooves of the stator 14 as described in document WO-92/06527.
- four electrically conductive elements are mounted radially with superposition by groove as described in the request document.
- the rotor 16 is here a claw rotor provided with an electric coil 62 of cylindrical excitation, which is mounted between two metal plates 64 and 66 each having claws at their outer periphery, which extend axially in the direction of the other plate 66 and 64.
- the ends of the winding 62 are connected to the rings 20 in a known manner by wire connections.
- the plates 66, 64 are here extended at their internal periphery by a cylindrical portion to carry the winding 62.
- a cylindrical core is mounted on the shaft 18 and is interposed between the two plates to carry the winding 62.
- Each plate-claw assembly constitutes a polar wheel here in magnetic steel.
- Each pole wheel is fixed to the shaft by means of knurled parts of this shaft 18.
- the claws are angularly offset from one wheel to the other so that a claw of the plate 64 is inserted between two adjacent claws of the plate 66, and vice versa.
- the alternator is therefore here with internal ventilation, each plate 64,66 carrying a fan respectively 102,104 adjacent to the part 15,17 concerned of the casing.
- Each part 15, 17 of casing 12 is perforated for air circulation and centrally carries a ball bearing 26, 28 for support for rotation of the front and rear ends of the shaft 18 respectively.
- the rear bearing 17 carries an arrangement 23 for rectifying the alternating current produced by the stator and a brush holder 25, the brushes of which cooperate with the slip rings 20.
- a protective cover 27 integral with the rear bearing 17 and covering, on the one hand, the brush holder 25, connected in known manner to a regulating device for regulating the current and the voltage of the winding 62, and, on the other hand, the rectifying arrangement 23, provided with diodes mounted here head to tail as visible in FIG. 1.
- the rectifying arrangement 23 comprises the rear bearing 17 carrying the so-called negative diodes, a positive metal radiator carrying the so-called positive diodes and a connector interposed between the rear bearing and the positive radiator in particular to connect the diodes as described in document FR A 2 734 425 to which reference will be made for more details.
- the front 15 and rear 17 bearings are metallic, here based on aluminum, being of hollow form delimited by a transverse flange carrying the ball bearing 26, 28 concerned and by a peripheral rim of axial orientation, one of which is here internally shouldered to carry the stack of sheets of the stator body by means of screws 29 bearing on a crown belonging to an annular spacer (not referenced) with a supporting fold on the bearing 15 to tighten the body 22 between the crown and the aforementioned shoulder.
- the bearing 17 also has a shoulder so that the body 22 is clamped between the two shoulders of the bearings 15,17.
- the flanges and the flanges in known manner, have openings for air circulation.
- the flanges have openings facing the axial ends of the windings 32, called a bun, extending in axial projection relative to the body 22 of the stator 14, while the flanges have openings facing the blades of the fans 102, 104.
- These bearings are connected to fixing using screws or tie rods as visible for example in Figure 1 of the aforementioned document EP B 0 515 259.
- a single fan is installed outside at the level of the pulley.
- the bearings 15, 17 are provided internally with channels for circulation of a coolant, such as the coolant of the engine of the motor vehicle.
- the pulley 30 is internally hollow for housing the threaded front end 40 of the shaft 18, a nut 41 and a support washer 42 interposed between the transverse bottom 43 of the pulley 18 and the nut 41 screwed onto the threaded end 40.
- the bottom 43 is perforated centrally, as well as a first annular spacer 44 and a second annular spacer 45, for passage of the shaft 18.
- the inner ring 50 of the ball bearing 26 is clamp mounted on a smooth cylindrical surface 70 of the shaft 18; the spacers 44,45 being mounted on either side of this ring 50.
- the outer ring 51 of the bearing 26 is mounted in a housing formed at the internal periphery of the transverse flange 19 of the front bearing 15, that is to say centrally in the front bearing 15.
- the housing is delimited by an annular bearing of axial orientation 52 extended radially inwards by a transverse wall 53 surrounding the first spacer 44 with little play.
- the front face of the ring 51 bears on the external periphery of the portion 53, while the rear face of the ring 51 is in contact with a washer 55 fixed by screws on the flange 19 above the seat 52 in contact with the external periphery of the external ring 51.
- the ring 51 is therefore clamped between the washer and the wall 53.
- the first annular spacer 44 is located axially between the bottom 43 of the pulley 30 and the internal ring 50 of the ball bearing 26.
- the rings 50, 51 have tracks for the balls 54 interposed radially between the rings 50, 51.
- the bearing 26 is advantageously conventionally lubricated with grease and seals integral with the outer ring 51 are provided at each axial end of the bearing to prevent the grease from escaping so that the bearing 26 is sealed.
- a cage is provided for retaining the balls 54.
- the seals (not referenced) of the bearing 26 are shown by lines. These seals are set back relative to the axial ends of the bearing 26.
- the seals are integral with the outer ring 51 of the bearing and are in contact with the outer periphery of the inner ring 50.
- the first spacer 44 is of tubular shape having at its front end an annular rim of transverse orientation for contact with the bottom 43. As a variant, the first spacer is in one piece with the bottom 43 then thicker.
- the second spacer 45 is tubular in shape and is located axially between the inner ring 50 of the bearing 26 and the plate 64 of the adjacent pole wheel.
- the shaft 18 is shouldered at the rear face of the plate 66 of the other pole wheel.
- FIG. 2 shows a rotor shaft 18 in accordance with the invention.
- the shaft 18 is the rotor shaft of a rotary electrical machine which is for example an alternator or an alternator-starter of a motor vehicle.
- the shaft 18 comprises a cylindrical body comprising a convex knurled section 71 intended to receive the pole wheels. More precisely, the pole wheels are force fitted onto the section 71 which cuts grooves therein.
- the shaft 18 has an axis of axial symmetry XX constituting the axis of rotation of the rotary electric machine. with an axis of rotation XX, the knurled section 71, is extended towards the front by a cylindrical intermediate section 72, of external diameter greater than the external diameter of the body 71 of the shaft 18.
- This intermediate section advantageously comes integrally with the tree.
- this intermediate section may be a ring welded to the shaft 18.
- This intermediate section 72 is delimited axially by a front shoulder 73 of transverse end bearing against the ball bearing 26 and by a rear shoulder 74 of transverse end bearing the front pole wheel 64.
- the intermediate section thus forms a spacer delimited by two shoulders 73, 74 of radial orientation.
- the shaft 18 does not have an intermediate section 72.
- This shaft has the advantage of being economical thanks to the elimination of the machining operation on either side of the intermediate section.
- this smooth shaft has a groove 201 for crimping the rear pole wheel.
- the front shoulder 73 is extended by a smooth cylindrical seat 70 intended to receive the ball bearing 26.
- the smooth cylindrical seat 70 is extended forward by a fluted outer section of front free end 75 comprising at its outer periphery a alternating grooves 76 axial and teeth 77 axial.
- the outer grooved section 75 is externally in diameter in stages, the bottom circle of the bottoms of the grooves 76 being identical. More specifically, the fluted outer section 75 comprises at the rear a short section 78 comprising teeth 77 of external diameter equal to the external diameter of the cylindrical seat 70. At the front, the fluted external section 75 therefore comprises teeth of diameter lower than that of the teeth of the section 78. At the front, the teeth 77 of the fluted external section 75 are intended to cooperate in clamping with grooves in the pulley 30.
- the ball bearing is fitted with adjusted tightening both on the smooth cylindrical seat 70 and on the short fluted section 78.
- the ball bearing is essentially mounted on the smooth cylindrical part 70.
- the free front end of the teeth 77 has a chamfer 79 intended to facilitate assembly of the pulley.
- the free front end of the shaft 18 comprises a pilot end piece 80 also intended to facilitate the mounting of the pulley.
- This pilot tip also has a chamfer 81 facilitating the mounting of the pulley.
- the external diameter of the pilot end piece is substantially equal to the internal diameter of the teeth 77 'of the pulley.
- the free front end of the shaft advantageously has internally a tapped blind hole 82 coaxial with the axis X-X intended for mounting the pulley on the shaft.
- the shape retained for the toothing of these grooves is the known shape called "developing from a circle” defined by the involute function commonly used for gear shapes. This form of toothing is advantageously produced by cutting or rolling.
- the free front end of the shaft 18 includes a threaded front end section 200 intended to receive a nut intended for mounting the grooved pulley on the grooved shaft 18.
- the pulley 30 comprises a massive part of body 90 produced in the form of a thick disc which is extended forward, at its radial external periphery, by an annular cylindrical skirt 91 of axial orientation and of axis XX.
- the massive body part 90 and the annular cylindrical skirt 91 has a profiled external radial surface 92 forming a peripheral functional zone intended to cooperate with a drive belt, not shown, according to a known design.
- the radial surface 92 could be toothed to cooperate with a toothed belt. It all depends on the applications.
- the pulley 30 is produced for example by molding in one piece, and its body 90 is extended, at its inner radial periphery, by an annular pulley hub 93 which is in the form of a thick bush of axial orientation which generally extends axially forwards with respect to the transverse body 90.
- the annular pulley hub 93 in the form of a socket thus generally delimits an axial through hole 94 which passes through it and which comprises, in accordance with the teachings of the invention, an internal grooved section 95 consisting of alternating axial grooves 76 ′ and teeth 77 ′ axial capable of cooperating with the grooved outer section 75 of the shaft 18 of the rotor, so as to allow assembly of the pulley 30 by force fitting its hub 93 onto the shaft 18.
- the annular hub 93 of the pulley is delimited axially towards the rear by a transverse shoulder 96 formed at the rear free end of a tubular axial extension 97 of reduced diameter of the hub 93.
- this shoulder 96 comes axially into abutment against a transverse face of a front axial end 98 of the inner ring 50 of a ball bearing 26 before guiding in rotation the rotor shaft 18.
- the shoulder 96 of the pulley 30 could also come into abutment against a corresponding shoulder formed directly on the rotor shaft 18.
- a front stage recess in diameter 99 suitable to receive, for example, a large support washer 108 for axially blocking the force-fitted pulley.
- the front recess 99 is chamfered at its front end.
- Figures 5a, 5b and 5c describe as an example a method of mounting the pulley 30 on the shaft 18 according to the invention.
- the pulley 30 is mounted on the shaft 18 as follows:
- a threaded rod 100 is screwed into the threaded hole 82 of the shaft.
- the pulley is indexed by placing its grooves 76 'opposite the teeth 77 of the shaft. - At this stage of the process, as a variant, the pulley can be heated, for easier fitting up to a temperature for example of 170 degrees.
- a spacer 102 is mounted in the front central recess 99 of the pulley, the rear face of the rear tubular end 103 of the spacer 102 abutting against the front transverse bottom 43 of the pulley, while the threaded rod passes freely inside a bore 104, from the spacer 102, coaxial with the axis XX.
- FIG. 5b represents an assembly of a pulley on a shaft according to the invention, at the end of the screwing operation. - the threaded rod 100 carrying the spacer 102 and the nut 101 are then removed.
- the locking of the threaded rod 100 is carried out using an additional tool.
- the threaded rod 100 has at its free end before a blind central hole 106 which, for example, is internally serrated.
- a complementary tool externally serrated which is introduced into the serrated blind hole 106 of the threaded rod for its locking in rotation.
- the nut 101 when screwed, transmits an axial force towards the rear on the front face 105 of the spacer, this axial force then being transmitted on the transverse bottom 43 of the pulley by the cylindrical surface 103 of the spacer.
- a screw 107 is screwed into the threaded hole 82 of the front end of the shaft 18, after having placed a wide washer 108 against the transverse bottom 43 of the pulley.
- the mounting of the grooved pulley on the shaft 18 is carried out according to the same principle as the mounting of a grooved pulley on the shaft corresponding to FIG. 2 described above.
- the mounting process can be broken down as follows: - the annular extension of axial orientation 97 of the pulley 30 is brought to the level of the pilot end piece 80.
- the pulley is indexed by placing its grooves 76 'opposite the teeth 77 of the shaft. - At this stage of the process, as a variant, the pulley can be heated, for easier fitting up to a temperature for example of 170 degrees.
- a washer can be placed in the nut and the front face of the pulley. Once the pulley has been assembled, the nut of the thread 200 is removed, and this can be reused for another assembly. Obviously, it is possible to leave the nut on the thread for safety reasons, although it does not contribute to the transmission of torque.
- the pulley can be envisaged such as for example a pusher device which makes it possible to push the grooved pulley on the grooved shaft 18 until the latter comes into abutment against the bearing.
- the toothing is "conical", in other words that the thickness of the tooth varies linearly over all or part of the useful length. At the beginning the assembly is easy, the pulley shaft adjustment being slippery, and as the engagement progresses the tightening increases.
- the shaft Due to the belt pulley transmission, the shaft works in rotary bending. It is therefore advisable to optimize the geometry and the process of obtaining the grooves for maximum resistance to fatigue.
- the splines of the shaft are made by rolling in full material.
- the adjustment of the splines is a tight adjustment so that there is no possible angular play between the shaft 18 and the pulley 30. Otherwise, acyclisms, sudden variations in engine speed and reversals of the direction of the torque passing through the connection could lead to knocking or even shearing of the splines and rupture of the shaft.
- the tightening is between 50 and 200 microns.
- the quality of the assembly and the value of the maximum transmissible torque no longer depend on the surface conditions of the various components in contact with the pulley.
- the transmission of the torque is achieved by means of a positive connection by splines on the shaft and the pulley.
- an axial timing device such as the following:
- the axial setting of the pulley on the shaft is a direct consequence of the tightening of the pulley / shaft adjustment.
- Another variant consists in making the shaft so that its end has a cutting edge around the entire periphery of the teeth while the pulley has a smooth bore.
- the groove of the pulley will be made by removing chips when fitting the shaft. In this case it is necessary to carry out a surface hardening of the toothing of the shaft.
- the parts cannot be reused.
- the maximum torque which can be transmitted by the assembly is no longer dependent on the axial clamping of the pulley, that is to say the tightening torque of the nut according to the state of the art.
