Description

Technical Field

[0001] The utility model relates to the field of new energy vehicles, and in particular to an improved speed reduction mechanism housing. Background Art

[0002] A search of Chinese patents revealed the publication number CN210920055U, which describes a compact reducer housing comprising a housing, a worm cavity disposed in the upper portion of the housing, a worm wheel cavity disposed in the lower portion of the housing, the worm cavity and the worm wheel cavity being interconnected and perpendicular to each other; and a motor cavity disposed at the top of the worm cavity. The compact reducer housing manufactured using the technical solution of this utility model has a compact structure, saves materials and space, reduces production costs, and enables high-speed reduction and vertical transmission. It can be used in equipment with limited space and high reduction ratio requirements, such as elevators.

[0003] The existing reducer housing has poor sealing performance. Generally, a sealing gasket is set between the reducer housing and the cover plate for sealing. During use, the sealing gasket will be squeezed by the cover plate and the housing, causing the sealing gasket to deform. The sealing gasket is affected by various factors for a long time, and the elasticity of the sealing gasket will be reduced, which will reduce the sealing performance between the cover plate and the housing, easily causing oil leakage, affecting the service life of the reducer, and making it inconvenient to replace the engine oil. During use, the reducer needs to be regularly replaced with engine oil. When replacing the engine oil of a general reducer, the reducer housing needs to be opened for replacement and then installed after replacement. The replacement process is relatively cumbersome, which increases the workload and reduces the replacement efficiency. In order to solve the above problems, we propose an improved reduction mechanism housing. Utility Model Content
