This invention relates to mechanical engineering, in particular to vehicle transmissions.

The purpose of the invention is to reduce the size, weight, simplify adjustment and design by using standard bearings.

FIG. 1 of the image. The main gearing scheme, FIG. 2 shows section A-A in FIG. one.

The drive bevel gear 1 of the main gear with the shaft 2 is installed in the housing 3 on two bearings.

The front bearing 4 - floating is fixedly connected to the shaft and can move axially with it relative to the housing. The rear bearing 5 is locking. Its outer ring 6 is fixedly mounted in the housing and fixed by the stop cover 7.

The inner ring 8 of this bearing is fixedly mounted on a stepped sleeve 9, one step (not shown) of which is a collar for the axial support of the fixing bearing 5. In the annular groove (not shown) of the sleeve 9 there is a retaining ring 10, which is the second axial support of the podshpnik 5. The sleeve 9 has a mating portion 11 with the shaft 2, which provides free axial movement of the sleeve along the shaft. On the section 12 of the sleeve 9. internal thread is completed, it is coupled with the thread that responds to it at the end 13 of the shaft 2.

; On the outer surface of the sleeve 9, flats 14 are made, which are wrench elements. At the end of the shaft 2 is made a slot 15 under the screwdriver. The shaft 2 is fixed relative to the sleeve 9 by the lock nut 16,

The collet 9c with the lock nut 16 forms the axial position adjustment device for the pinion gear 1. It is connected with the driven bevel gear 17.

j The device operates as follows.

If necessary, adjust the gearing bevel gears 1 and 17

a wrench holding the sleeve 9 and through the slot 15 turn the shaft 2 with a screwdriver. The shaft 2, turning in the thread of the sleeve 9, is displaced in the axial direction, ensuring the displacement of the gear 1. After finding the desired position of the last shaft 2 is fixed relative to the sleeve 9 by the lock nut 16.

Claims (3)

Invention Formula .1, the main gear of the vehicle, containing driven and driving bevel gears in the housing, of which the shaft is mounted in the housing on the floating and fixing bearings, and the axial position adjustment device of the drive gear, including a sleeve connected to one of the rings of the fixing bearing elements with a wrench and threaded, a return thread on one of the transmission elements, and a lock nut, characterized in that, in order to reduce overall dimensions, weight, to simplify adjustment and construction, t use standard bearings, sleeve placed on the shaft and coupled to the inner ring of the locating bearing, the thread on the sleeve - inner - response her thread vtolnenag on the shaft, the outer ring of the locating bearing is fixed in the housing of the axial-movement, a lock nut arranged on the shaft, 2, the main transmission according to claim 1, characterized in that the sleeve is made stepped with an annular groove, one step is a collar for the axial support of the fixing bearing, and a circlip, which is the second axial support of the fixing bearing, is placed in the annular groove. 3.
