WHEEL PLANETARY GEARBOX Russian patent published in 2008 - IPC B60K17/16 F16H48/08 

FIELD: machine building.

SUBSTANCE: wheel planetary gearbox consists of driving bevel gear (1), installed at semi-axis (2), driven bevel gear (3), installed at the axle splines (4), cone satellites (5), installed at cross pins (6). Pins (6) are installed in the mating holes of internal body (7) and external body (8). Bodies (7, 8) are mutually connected by bolts (9). A deepening for thin-wall sleeve (10) is provided at the bodies' mating location, at bodies' external surface. Sleeve (10) is installed flush to the external surface of bodies. Circular grooves are made in the deepenings of bodies (7, 8) from different side of cross pins (6). O-rings (11) are installed in the circular grooves. The internal surface of thin-wall sleeve (10) interacts with O-rings (11).

EFFECT: simplification of sealing of mated surfaces of internal and external bodies; maintaining the overall dimensions of gearbox; ensuring sufficient strength the tho gearbox.
