Definitions

  • the present invention relates to a rotary pneumatic starter for an internal combustion engine.
  • pneumatic starters have advantages over electric starters.
  • pneumatic starters are more powerful and lighter, at equal volume, than electric starters, and they are also generally explosion-proof.
  • the main elements of a pneumatic starter for an internal combustion engine are a pneumatic motor, usually of the gear type, a transmission intended to rotate a driving pinion, and a device for translational movement of this driving pinion in order to that it can mesh with a toothed organ to launch.
  • pneumatic starters An important problem posed by these pneumatic starters is that of overspeeds. Indeed, it is known that pneumatic motors wear out very quickly and can even be brutally damaged when they are driven at too high speed. We have therefore used, in known pneumatic starters, a device of one type or another intended to prevent this overspeeding of the pneumatic motor when the internal combustion engine to be launched has actually started and drives the pneumatic motor of the starter. through the drive pinion.
  • a freewheel clutch is mounted between the drive sleeve in rotation of the drive pinion and a sleeve which is itself driven by the pneumatic motor.
  • the drive pinion effectively transmits a torque to the member to be driven
  • the freewheel is blocked and the drive pinion is effectively driven by the pneumatic motor.
  • the drive pinion is driven and unlocks the free wheel so that it drives the sheath but not the sleeve which is engaged with the pneumatic motor. The latter is therefore not overspeeded.
  • the invention relates to a pneumatic starter of the general type considered, that is to say comprising a pneumatic motor, a transmission intended to control the drive. ment in rotation of a drive pinion, and a drive device in translation of this pinion.
  • the starter ensures the progressive introduction of a drive pinion engaged with a toothed member to be driven.
  • the direction of rotation of the drive pinion can be easily reversed.
  • the starter advantageously contains various components such as a lubricator, an air supply control, etc.
  • a device incorporated in the starter ensures the automatic decoupling of the drive pinion when the pneumatic motor reaches a predetermined speed and adjustable within a certain range.
  • the invention relates to a pneumatic starter for an internal combustion engine, for example a diesel engine, of the type which comprises a rotary pneumatic engine, a transmission, a drive device in translation with a pneumatic cylinder, and a pinion of drive intended to drive itself a toothed member of the internal combustion engine, this drive pinion being intended on the one hand to be driven in rotation by the pneumatic motor via the transmission, and on the other hand to be driven in translation, in a direction substantially parallel to its axis, by the drive device in translation with a pneumatic cylinder.
  • the pneumatic cylinder of the drive device in translation is a double action cylinder in the same direction, comprising a piston having a first and a second actuation surface, so that, in a first part of the stroke of the piston in said direction, the pressure of the compressed air is applied only to the first actuation surface whereas, in a second part of this stroke in the same direction, it is applied to the first and the second actuation surface.
  • the jack is mounted in the axis of the support pinion support shaft.
  • the cylinder also advantageously constitutes a drawer for controlling the supply of the pneumatic motor with a high flow rate.
  • the transmission advantageously comprises a pinion, preferably with straight teeth, integral with a rotor of the pneumatic motor and meshing with a toothed ring formed on a sheath having internal grooves, and the drive pinion is mounted on a grooved shaft whose grooves cooperate with those of the sheath.
  • the drive pinion and the pinion and the gear ring of the transmission all have straight teeth.
  • the two rotors of the pneumatic motor are placed at the same distance from the axis of rotation of the sleeve so that the pinion which meshes with the toothed crown of the sleeve can be integral with one or the other rotor of the pneumatic motor; in this way, the direction of rotation of the drive pinion can be chosen at will.
  • the rotors of the pneumatic motor are formed from plastic which has a low specific gravity so that the pneumatic motor has low inertia.
  • the starter comprises in integrated form various accessories such as a lubricator and a compressed air supply control.
  • the decoupling of the drive pinion is automatically controlled by a centrifugal switch mounted directly in the starter.
  • This centrifugal switch is advantageously mounted at the end of the shaft of one of the rotors of the pneumatic motor, and the return of the centrifugal switch to the rest position is ensured by a spring which exerts an antagonistic adjustable force making it possible to adjust the trip threshold.
  • the pneumatic motor according to the invention has many advantages. First, it has small dimensions and is twice as light as an electric starter of the same size while being five times more powerful. It does not require any maintenance.
  • the direction of rotation can be chosen by simply moving a pinion.
  • the decoupling is controlled automatically according to the speed of the pneumatic motor of the starter itself and not according to a parameter derived from the operation of the associated internal combustion engine.
  • FIG. 1 represents the main elements of a pneumatic starter according to the invention, intended for the launching of an internal combustion engine, advantageously a diesel engine.
  • the starter first comprises a body which is not shown specifically but which is simply indicated by the hatching in FIG. 1.
  • the first important starter member is a pneumatic motor 10 shown in the form of a conventional gear motor.
  • Two rotors 12 and 14 have thus been shown meshing with each other and each mounted on a axis 16, 18.
  • the inertia of this pneumatic motor is reduced by forming the rotors 1 2, 14 in a light and wear-resistant plastic material, for example in "Nylon" while the axes 16 , 18 are made of steel. These axes are mounted on needle bearings 20, in a conventional manner.
  • the rotational speed of the rotors 12 and 14 is for example between 10 and 20,000 rpm. However, these rotors can rotate up to speeds of the order of 50,000 rpm without significant deterioration.
  • the pneumatic motor is coupled to a transmission 22.
  • the latter intended to transmit the rotational movement of the rotors to the motor to be launched, comprises a spur gear 24 mounted on the axis 18 and meshing a toothed crown 26 secured to a sheath 28.
  • the pinion 24 has been shown mounted at the end of the axis 18, it should be noted that, according to an advantageous characteristic of the invention, the two axes 16 and 18 are at the same distance from the crown 26 so well that the pinion 24 can be mounted at the end of one or the other axis 16, 18. As the two rotors 12 and 14 rotate in opposite directions, the ring gear 26 is driven in one direction or the other depending on whether the pinion 24 is mounted on one rotor or the other.
  • This characteristic is important because it allows the use of the same pneumatic starter according to the invention with motors of different types or with a different positioning relative to the driven member.
  • the sleeve 28 can rotate freely relative to the housing and it is carried for this purpose by a bearing 30 with cylindrical rollers with high radial load capacity and a ball bearing 31 receiving the axial stresses keeping this sleeve in translation. It includes, on the inside, grooves 32 which lead to a shoulder 34 whose role is indicated in the remainder of this specification.
  • the pinion 36 of the starter intended to attack the toothed member 37 of the motor to be driven, is mounted at the end of a shaft 38.
  • the latter can slide in the sheath 28 and it has longitudinal grooves 40 intended to cooperate with the grooves 32 of the sleeve 28.
  • the grooves 32 and 40 of the sleeve and of the shaft are longitudinal. Their machining is therefore simple and inexpensive.
  • the shaft 38 carries a disc 42 constituting a bearing surface for a spring 44, the other end of which bears on the shoulder 34 of the sheath.
  • the disc 42 can also advantageously guide the end of the shaft to which it is fixed inside the sheath 28, when the shaft moves in translation.
  • the spring 44 has a significant stiffness, much greater than that of the springs usually used in pneumatic starters for the return of the drive pinion. This characteristic, allowing rapid decoupling, is possible according to the invention thanks to the assembly described below.
  • Another essential element for the starter according to the invention is the device 46 for translational drive with a pneumatic cylinder.
  • This device comprises a piston 48, extended by a rod 50 intended to come into abutment against the rear face of the disc 42.
  • the piston 48 of the jack is in the form of a double cylinder.
  • a first cylindrical part defines a first surface 52 turned to the left in FIG. 1 for the application of a force by the fluid under pressure.
  • the larger diameter portion of the cylinder 48 defines a second surface 54, also turned to the left in FIG. 1.
  • An O-ring 55 is housed in the body around the cylindrical portion of smaller diameter of the piston 48 so that , when compressed air arrives from the left in FIG. 1, only the surface 52 is subjected to the pressure of this compressed air. It is only when the jack 48 has moved sufficiently to the right that the surface 52 exceeds the seal 55 that the compressed air comes to exert a force on the surface 54.
  • the seal 55 can also be omitted.
  • the pneumatic cylinder which is single acting in the example considered, however has a first part of the stroke in which it is pushed back with a certain force and a second part of the stroke in which it is pushed back with a greater force.
  • first stroke part only the surface 52 is subjected to the pressure of the compressed air while, in the second stroke part, the two surfaces 52 and 54 are subjected to the pressure of the compressed air.
  • the components of the pneumatic circuit are now considered more precisely.
  • the compressed air at high pressure arrives via an inlet channel 56 and opens into a chamber 58.
  • This contains a ball or a valve 60, bearing against a seat formed by the edge of a hole 62.
  • a spring 64 bearing against the ball or the valve 60 on the one hand and against a stop ring 66 on the other hand, holds the ball or the valve 60 in cooperation with its seat .
  • a pipe 68 opens out from the chamber 58, upstream of the ball or of the valve 60 so that it always receives the compressed air coming from the channel 56.
  • the hole 62 which delimits the seat of the ball 60 opens, on the other side, into a channel 70 of large section.
  • the inlet channel 56, the chamber 58, the hole 62 and the channel 70 have a high section.
  • the other pipes, such as pipe 68 have a small section.
  • This channel 70 opens out through an orifice 72 in the chamber which contains the two rotors 12 and 14 of the pneumatic motor.
  • a piston 76 When compressed air is admitted into the left part of chamber 78 (in FIG. 1), the piston 76 is pushed to the right and moves the ball 60 away from its seat. At this time, the compressed air from channel 56 can reach motor 10 with a high flow rate.
  • Compressed air is admitted on the left side of the chamber 78 by means of a conduit 80 of small section, coming from the chamber in which the piston 48 moves.
  • the compressed air can only be transmitted through this pipe 80 when the surface 52 of the piston 48 has passed the O-ring 55 and when the surface 54 has passed the mouth of this pipe 80.
  • a screen filter 90 is mounted at the entrance to this chamber 82 and is intended to retain the dust and particles which can be entrained by the compressed air transmitted by the channel 56.
  • the ball 86 can be dislodged from its seat by a rod 92 which is integral with a piston 94 movable in the chamber 82.
  • the latter has two pipes 96 and 98.
  • the pipe 96 joins the rest of the pneumatic circuit while the pipe 98 leads to the atmosphere.
  • the rod 92 can be controlled either by a manual button 100, or by compressed air transmitted by a pipe 102, for example low pressure air such as 8 bars.
  • the pipe 96 opens on the one hand into a pipe 104 and on the other hand into a lubricator shown purely by way of illustration because its use is not essential.
  • This lubricator essentially comprises a cylindrical chamber 106 at one end of which opens the pipe 96.
  • This chamber 106 is also connected with two lines 108 and 110. In addition, it contains a drawer 112 which is pushed to the left in FIG. 1, by a spring 113.
  • the line 108 is connected to a reservoir 114 of oil by means of a valve 116.
  • the pipe 110 opens into the pipe 104.
  • the drawer 112 has two spans connected by a part of reduced diameter. In the position shown in Figure 1, the pipes 108 and 110 are not in communication, and a dose of oil fills the space between the two surfaces.
  • the slide 112 moves to the right and the space which separates the two ranges comes into communication with the line 110 so that a dose of oil enters the line 104 and allows the lubrication of the various elements of the pneumatic circuit, placed downstream.
  • Line 104 downstream of line 110, separates into two lines 118 and 120.
  • the first transmits compressed air to the end of the pneumatic cylinder 46, already described.
  • the other 120 contains a check valve 122 and opens into the air motor supply chamber 70.
  • the operator presses the button 100 or controls the transmission of compressed air through the pipe 102.
  • the rod 92 enters the chamber 82 and moves the piston 94 which clogs the end of the vent pipe 98.
  • the rod 92 separates the ball 86 from its seat.
  • Compressed air therefore reaches the line 104 and the lubricator, the operation of which has been described above.
  • the lubricator therefore transmits a dose of oil to the line 104.
  • the compressed air reaches on the one hand the line 120 and on the other hand the line 118.
  • the air from the line 120 opens the valve 122, enters in the channel 70 and begins to rotate the motor 10.
  • the air flow is low so that the rotors 12 and 14 rotate slowly. From this moment, the pneumatic motor 10 drives the drive pinion 36 via the pinion 24 and the ring gear 26. The pinion 36 therefore begins to rotate, but at low speed when it is not yet in taken with the toothed member 37 of the engine to be launched.
  • the air passes through the pipe 118 to the pneumatic cylinder 46.
  • the air pressure is only applied to the relatively small surface 52, so that, taking into account the stiffness of the spring 44, the piston 48 slowly moves to the right (in FIG. 1) and thus advances the pinion 36 towards its position of cooperation with the toothed member 37.
  • the pinion 36 has therefore slowly engaged the toothed member 37 and it can be launched at high speed without risking any damage to any member.
  • the end surface 52 of the cylinder 48 then exceeds the seal 55 and, simultaneously, the air pressure is applied to the second surface 54 of the enlarged part of the cylinder so that the latter is pushed strongly to the right on Figure 1 and thus ends the engagement of the pinion 36 and the member 37, while subsequently maintaining the pinion in this working position.
  • the enlarged part of the cylinder 48 opens the pipe 80 so that the compressed air reaches the left part of the chamber 78.
  • the piston 76 is then driven to the right and, via the rod 74, it pushes the ball 60 away from its seat.
  • the compressed air from the channel 56 enters with a high flow rate into the hole 62 and into the channel 70 so that the motor 10 is controlled by a high flow of air.
  • the motor therefore accelerates quickly and it drives the pinion 36 and the toothed member 37 more and more quickly, with a high torque.
  • the operator When the engine has been started, the operator removes the button 100 or interrupts the transmission of compressed air through the pipe 102.
  • the spring 88 then pushes the ball 86 (and possibly the rod 92) so that the compressed air n 'is no longer transmitted to the pipe 96 which is on the contrary connected to the atmosphere by the pipe 98.
  • the pipes 118 and 120 therefore no longer receive compressed air.
  • the piston 48 of the pneumatic cylinder is therefore no longer pushed to the right and the spring 44, thanks to its high stiffness, quickly brings the shaft 38 to the left, pushing the piston 48 to the position shown in FIG. 1.
  • FIG. 2 represents a variant of a pneumatic starter according to the invention. Elements identical or analogous to those in FIG. 1 bear identical references. Thus, the pneumatic motor, the transmission, the pneumatic cylinder, the hydraulic control circuit and the lubricator are practically identical to the corresponding elements of FIG. 1. However, this embodiment of FIG. 2 differs from that of FIG. 1 in which it includes a centrifugal switch driven by one of the rotors and interposed in the pipe 118.
