Sealed integrated main cone bearing unit

Abstract

The invention discloses a sealed integrated main cone bearing unit which comprises a main shaft. The left side of the surface of the main shaft is sleeved with a bevel gear. The surface of the main shaft is sleeved with an inner bearing. The inner bearing is located on the right side of the bevel gear. The surface of the inner bearing is sleeved with a bearing seat. Through cooperative use of theinner bearing, a first groove, the bearing seat, an outer bearing, a small end face, a small flange, a large flange, a large end face, a second groove, a sealing ring, a shaft sleeve and a spacer, theproblems that an existing commercial vehicle sealed integrated main cone bearing unit is complex in assembly and high in machining accuracy requirement are solved, the sealed integrated main cone bearing unit has the advantages of being easy to assemble and low in machining accuracy requirement, the structure is reasonable, time is saved in the assembly process, part machining cost is saved, thesealing performance of the sealed integrated main cone bearing unit is better, the risk of bearing failure due to oil leakage is reduced, and the defects in the prior art are effectively overcome.

Description

technical field [0001] The invention relates to the technical field of automobile production, in particular to a sealed integrated main cone bearing unit. Background technique [0002] Bearing is an important part in automobile production. Its main function is to support the mechanical rotating body, reduce the friction coefficient during its movement, and ensure its rotation accuracy. Its function should be support, that is, the literal interpretation is used Bearing, but this is only part of its role, the essence of support is to be able to bear radial loads. It can also be understood that it is used to fix the shaft. Bearings are included in the quick and easy automatic selection, which is to fix the shaft so that it can only achieve rotation, while controlling its axial and radial movement. If the motor does not have a bearing, it cannot work at all, because the shaft may move in any direction, and the motor It is required that the shaft can only rotate during work. In...
