Definitions

the invention relates to a self-propelled spindle for textile machines according to the preamble of patent claim 1.
a spindle shaft is rotatably connected to a rotor shaft.
the shaft carrying the rotor of the electric motor is mounted on both axial sides of the rotor in a stator housing which is elastically connected to the motor housing fastened to a spindle bank.
the spindle shaft is connected in a rotationally fixed manner to a rotor of an electric motor.
the stator of the electric motor is arranged with its housing on a lower spindle housing, with which the known spindle can be attached to a spindle bank.
a bearing housing for supporting the spindle shaft is arranged in an elastically damped manner in the lower spindle housing.
the spindle shaft with its lower section and the rotor arranged thereon can be pulled out of the bearing housing or the stator in order to be exchanged for a new spindle shaft, but defects occur on the stator or on the bearings, so again the entire unit lower spindle housing - bearing housing - rotor with rotor housing can be replaced, which is associated with considerable material and cost.
the object on which the invention is based is to further develop a self-propelled spindle of the type mentioned at the outset so that, in the event of defects, the damaged components can be replaced quickly and with as little material as possible.
the centering and fastening flange provided on the bearing housing in accordance with the invention makes it possible to construct the spindle from three independently interchangeable assemblies which can be connected to one another quickly and easily.
the first assembly is formed by the holding element with which the spindle can be fastened to a spindle bench.
the second assembly consists of the bearing housing with the spindle shaft and the rotor of the electric motor, while the third assembly is formed by the motor housing with the stator located therein.
the spindle shaft-rotor-bearing unit with housing is available as a complete structural unit, it is possible to implement a closed bearing for the spindle shaft, so that no contaminants such as e.g. Flight can penetrate, which significantly increases the life of the bearings.
the embodiment according to claim 4 makes it possible to replace the individual modules with one another without the need to center them again. As a result, the repair and maintenance effort for a textile machine equipped with the spindles according to the invention is significantly reduced.
the embodiment according to claim 7 serves to further simplify the assembly.
the embodiment according to claim 8 results in permanent decoupling of the spindle vibrations from the spindle bench or the textile machine, since no damping elements subject to aging are required.
the embodiment of claim 9 allows the rotor of the electric motor to be zen in a particularly simple manner insert trically into the corresponding stator.
the self-propelled spindle has a tubular bearing housing 10 which has at its upper end a centering and fastening flange 11 with a central fastening section 20, to which a first or a second ring step for centering is connected upwards or downwards.
the bearing housing 10 is inserted with the second ring step 17 into a centering hole 21 of a biflex sleeve 13 serving as a holding element, the fastening section 20 of the bearing housing 10 resting on a fastening flange 19 of the biflex sleeve 13.
the fastening section 18 has a radially outwardly extending centering flange 26 with preferably three circumferentially distributed threaded bores 28 into which adjusting screws 29 are screwed in order to align the spindle on the spindle bank 12. Furthermore, a radially inwardly extending holding flange 30 is provided on the fastening section 18, which cooperates with a radially outwardly extending clamping flange 31 of a fastening bolt 32.
the fastening bolt 32 extends with a Ge winch section through an opening 33 in the spindle bank 12, a retaining nut 34 with an associated washer 35 being screwed onto the threaded section of the fastening bolt 32 extending through the spindle bank 12 in order to fasten the biflex sleeve 13 to the spindle bank 12.
a corresponding bolt section can be formed in one piece with the biflex sleeve 13.
the fastening bolt 32 there is a blind bore 36 which is open at the top and into which a damping spiral 37 is inserted.
the damping spiral 37 surrounds a damping pin 38 which is screwed into the bearing housing 10 from below with a corresponding pot section 39.
a sleeve 40 is provided which lies tightly against the outer circumference of the fastening bolt 32 and against the outer circumference of the bearing housing 10.
a foot bearing 42 and a neck bearing 41 are inserted into the bearing housing 10.
a storage sleeve 43 is arranged between the neck and foot bearings 41 and 42, which defines the distance between the neck and foot bearings 41 and 42.
the two bearings 41, 42 are designed as ball bearings, the inner raceways 44 and 45 of which are formed on the lower section of the spindle shaft 15.
the neck and foot bearings 41 and 42 each absorb axial forces acting on one side, whereby the neck bearing 41 prevents an axial displacement of the spindle shaft 15 upwards and the foot bearing 42 prevents an axial displacement of the spindle shaft 15 downwards.
the foot bearing is prestressed onto the neck bearing 41 by means of a spring 46.
the other end of the spring 46 which acts on the foot bearing 42, is supported on the upper end face of the pot section 39 assigned to the damping pin 38.
a spring-free axial mounting of the spindle is achieved by the spring 46 tensioning the neck bearing 41 with the foot bearing 42, as a result of which the drive power required for the spindle is reduced.
the bearing housing 10 is sealed at the top by a Teflon ring 47 placed on the neck bearing 41.
an opening 48 is provided in the bearing housing 10, which is covered on the inside by the storage sleeve 43 for the oil lubricating the bearings, so that no dirt can get into the area of the bearings 41, 42 through the opening 48 can.
the motor housing 14 has a centering bore 24, in the region of which a fastening flange 25 which extends radially outward is provided.
the motor housing 14 On the side opposite the center hole 24 the motor housing 14 has an opening through which the upper section of the spindle shaft extends with a spindle sleeve 53 made of a light metal, for example aluminum, arranged thereon.
Axial cooling fins 54 are also arranged on the outside of the motor housing.
the Biflex sleeve is placed on the spindle bench 12 and fastened to the spindle bench 12 with the fastening bolt 32 extending through the bore 33 in the spindle bench 12.
the damping spiral 37 is already inserted into the blind bore 36.
the sleeve 40 is attached to the outside of the fastening bolt 32.
the blind bore 36 is partially filled with damping oil.
the ring step 17 comes into engagement with the centering hole 21 so that the bearing housing 10 and thus the spindle shaft 15 can be inserted into the center of the Biflex sleeve 13.
the damping pin 38 enters the damping at the same time spiral, wherein the damping oil displaced by the damping pin 38 is prevented by the sleeve 40 from flowing out.
the bearing housing 10 is rotated such that the through holes 56 in the fastening section 20 are aligned with the threaded holes 57 in the fastening flange 19 of the Biflex sleeve.
the motor housing 14 with the stator 52 arranged therein is placed on the centering and fastening flange 11 via the spindle shaft 15, the centering bore 24 engaging with the ring step 16, so that the stator 52 is centered on the rotor 51.
the spindle is aligned by means of the centering screws 29 before the fastening screw 34 is tightened.
the electrical connection of the electric motor of the self-propelled spindle is carried out in a known manner, not shown.
