Problems solved by technology

There are also some disadvantages. The heat is generated during the meshing process of the internal gear of the wheel reducer. The wheel reducer is installed in the rim of the wheel, which makes its heat dissipation performance poor. During the braking process of the vehicle, the heat is transferred to the wheel reducer, which makes the temperature of the wheel reducer high
High temperature is easy to reduce the viscosity of the lubricating

Abstract

The invention provides a wheel-side reducer adopting grease separating lubrication. Leakage of a gear lubricant can be reduced, and the service life of bearings can be prolonged. The wheel-side reducer comprises a planetary part, a hub and a power input part. The input part comprises an input gear shaft and a shaft head, and the planetary part comprises a plurality of planetary gears which are engaged with the input gear shaft; the planetary gear shaft is sleeved with the multiple planetary gears in a corresponding mode, and the multiple planetary gears share the same gear ring which is fixedly arranged on a gear ring support; the gear ring support is connected with the shaft head, and the planetary gears, the planetary gear shaft and the gear ring are all arranged in a wheel-side shell; the hub and the wheel-side shell are detachably connected into a whole, and the hub is supported on the shaft head and the gear ring support through the inner bearing and the outer bearing; a first oil seal is arranged between the hub and the gear ring support, and a second oil seal is arranged between the hub and the shaft head through a oil seal seat; and the inner bearing and the outer bearing are arranged in a spaced mode, and a communicating channel is arranged between the inner bearing and the outer bearing.

Description

Technical field [0001] The invention relates to a wheel-side reducer, in particular to a wheel-side reducer with grease separation and lubrication, and belongs to the technical field of vehicle reducers. Background technique [0002] The wheel reducer was invented by American scientists in the 1950s. After continuous improvement, it is now widely used as the wheel reducer of the drive axle of mining dump trucks. It is also used in some electric vehicles and is directly driven by the motor. At present, the wheel-side reducer in the field of vehicle engineering mostly uses planetary gear trains to transmit power, forming a planetary gear wheel-side reducer. [0003] The planetary gear wheel reducer has the advantages of compact structure, large transmission ratio and strong carrying capacity. There are also some shortcomings. The wheel-side reducer generates heat during the meshing process of the internal gears. The wheel-side reducer is installed in the rim of the wheel, which make...
