    The present invention relates to starter gearing of the positive shift dentil type overrunning clutch wherein provisions are made for the resilient means to absorb the torsional loads on the housing body after the starter gearing has become engaged with the engine ring gear, thereby enabling the elimination of a bearing sleeve member under the pinion gear and enabling the use of smaller sized pinion gears, resulting in the use of said starter gearing on smaller pinion gear applications.

    The invention relates to mechanical engineering and can be used in starters for starting internal combustion engines.
    A starter drive mechanism is known, comprising a drive coupling half mounted on the drive shaft with axial and angular movement with slots and mounted coaxially on the drive shaft with axial movement of the driven gyulumuft gear with face-splined teeth, connected with the leading coupling half with the help of an intermediate case and with the help of an intermediate case. spiral teeth interacting with similar killings of the driven coupling half-gear l.
    However, the known mechanism is unreliable and has insufficient durability, since the axial forces arising in it are not depreciated.
    The aim of the invention is to increase reliability and durability by providing amortization of axial forces.
    The goal is achieved by the drive mechanism of a starter containing a drive coupling mounted with a drive shaft with axial and angular movement with slots and mounted axially with a coaxial movement on the drive shaft with a driven coupling drive shaft with axial face the coupling half with the help of an intermediate E tulku with end-oblique oblique teeth interacting with similar teeth of the driven half-coupling gear, provided with a slotted A sleeve spaced coaxially between the intermediate sleeve and the leading coupling half and connected to one of them by means of spiral slots, and on the other by means of straight slots, as well as by means for axial fixation of the slotted sleeve relative to the leading coupling half, while the slotted sleeve performed With an annular protrusion on the inner surface in contact with the end face of the driven half-coupling gear.
    The spiral slots on the spline hub are located on the outer surface, and the straight ones - on the inner surface, while the spiral splines are located on the inner surface of the drive half-coupling, and the straight splines - on the intermediate sleeve.
    On the spline hub, the spiral slots are located on its inner surface, and the straight spans are located on its outer surface, while the intermediate spigot has helical splines, and on the inner surface of the drive coupling half, the splines.
    The means for axial fixation of the spline hub is made in the form of radial protrusions located on the inner surface of the drive half of the coupling. The means for axial fixation is made in the form of a locking ring installed in a groove made on the inner surface of the leading coupling half. The driving coupling half is made in the form of a hub and a cup-shaped part connected to it, which covers the intermediate and splined sleeves. FIG. 1 shows the drive mechanism of a starter with a partial axial section and notch; in fig. 2 is the same as the embodiment. The drive mechanism of the starter (Fig. Located on the drive shaft 1, having a section with spiral slots 2, which are coupled with the spiral slots 3 of the leading coupling half, installed with possible angular and axial movement along them. Coaxial drive shaft installed the coupling half coupling gear 5 with the possibility of axial movement. The driven half-coupling gear 5 is made with face bevel teeth 6, (located on the flange 7, is made nominally with gear 8. In the central hole of the driven half-coupling gear 5 A sliding bearing in the form of a sleeve is inserted. The leading coupling half k is made in the form of a sleeve, on the part of the outer surface of which straight splines 10 are made, and on the butt of the radial face - a stage 11 in the form of a shoulder, which is a means for axial fixation of the spline sleeve 12. Washable splines of vedu half coupling if there is a spline sleeve 12, having spiral slots 13 on the outer surface, and straight splines on the inner surface 1. At the end of the splined sleeve on the inner surface side, there is a bore that develops an annular protrusion that fits An intermediate sleeve 16 is located on the spiral splines 13 of the spline sleeve 12, which have spiral splines 17 on the inner surface of which the intermediate sleeve 1b can be rotated and moved in the axial direction. At the end of the intermediate. the sleeves 16 are made of spiral teeth 18, interacting with the teeth of the driven coupling half 4. The tooth 6 on the driven coupling half 5 and on the intermediate sleeve 16 are sloped along the non-working surfaces. On the driving coupling half. The bowl-shaped body 19 is fixed by a retaining ring 20, disks 21 are mounted behind the straight splines 10 of the leading half-coupling and are fitted to an elastic ring 22 made, for example, of rubber. A spring 23 is placed between the disk 21 and the intermediate sleeve 16, which presses the helical teeth 18 and 6 on the intermediate sleeve 16 and on the driven coupling half-gear 5 FRIEND to a friend. The assembled mechanism is fixed by a retaining ring 2A installed at the end of the housing 19. The driving coupling half has an actuating ring 25, a retaining ring 26 and a damper spring 27. The embodiment of the drive mechanism is different in the construction of individual parts. The leading half coupling 28 is made in the form of a hub 29 and a cup-shaped part of the housing 30 connected to it. On the inner surface of the hub 29 there are spiral slots 31 interacting with the spiral slots 32 of the drive shaft 33, and on the inner surface of the housing 30 are straight splines Z. Schlitsev bushing 35 is located inside the body and has straight splines of the ST on the outer surface and spiral ones 37 on the inside. The intermediate sleeve 38 is located inside the spline sleeve 35 on the spiral slots 39 performed on its outer surface. The spring tO is located inside the intermediate sleeve 38 and rests on the disk 41 adjacent to the elastic ring C2. The means for axial fixation is made in the form of a locking ring 3 installed in the groove t, made on the inner surface of the housing 30, and adjacent to the straight slots of the BZ of the spline hub 35. The assembled parts are held by the locking ring 5, mounted on the spline hub 35. Tooth 46 and kj intermediate sleeve 38 and vedo. my half coupling 46 are pressed together. The operation of the mechanism is as follows. When moving the drive mechanism along the drive shaft 1, the gear wheel 8 engages with the gear ring of the engine. The starter drive shaft 1 rotates and transmits the torque to the drive coupling half through the spiral slots 2 and 3 from it to the spline sleeve 12 via straight slots 10 and 1, then to the intermediate sleeve 16 through the spiral slots 13 and 1 and to the driven coupling half 5 through teeth 6 and kj, which turns the flywheel.
    After starting the engine, the flywheel rotates faster than the gears, the teeth 6 and 18 unlatch and slip relative to each other, overtaking, and rotation is not transmitted from the engine to the drive shaft. The intermediate sleeve 1b along the spiral slots 17 and 13 moves away from the driven coupling half 5 of the compression spring -7. The axial force arising in the spiral slots 17 and 13 when moving the intermediate sleeve 16, closes on the radial protrusion 11 leading w
    the coupling half and the driven coupling half 5 is not transmitted.
    If the end of the gear 8 stops in the flywheel crown when the drive is inserted
    The engagement ring moves along the drive half coupling C, compressing the damper spring 27. With the subsequent rotation of the drive shaft, the gear teeth rotate relative to the crown teeth and take a position against the cavity between the teeth. At this moment, the whole mechanism under the action of the damper spring 27 will re-drive the drive shaft 1 and
    gear 8 will engage with the crown of the flywheel. The axial forces arising at the time of engagement are transmitted through the spline joints to the elastic ring 22, the shock-absorbing
    have gifts.
    The drive mechanism for the second option works the same way.
