Embodiment 1

[0037] This embodiment relates to a reducer ventilation structure, which is formed on the reducer. The reducer includes a reducer housing with a mounting cavity formed inside, and a reducer end cover blocked at the port of the mounting cavity. The reducer ventilation structure mainly It includes a cavity, an exhaust channel and an oil return channel, wherein: the cavity is formed in the upper wall of the reducer housing; the exhaust channel includes a first exhaust channel and a second exhaust channel, and the first exhaust channel is respectively connected to the installation The cavity communicates with the cavity, and the second exhaust channel communicates with the cavity and the outside of the reducer casing respectively; the oil return channel communicates between the installation cavity and the cavity.

[0038] The ventilation structure of the reducer in this embodiment, by setting the cavity, the oil return passage and the exhaust passage on the reducer housing, can can...

Embodiment 2

[0049] This embodiment relates to a reducer, still can refer to figure 1 As shown, including the reducer housing 1, an installation cavity 101 is formed in the reducer housing 1, a gear transmission mechanism not shown in the figure is installed in the installation cavity 101, and a deceleration gear is blocked at the port of the installation cavity 101. The end cover 2 of the reducer is formed with the reducer ventilation structure as in the first embodiment.

[0050] The reducer of this embodiment can effectively prevent lubricating oil from leaking, reduce the number of components of the reducer, and prolong the service life of the reducer by providing the reducer ventilation structure of the first embodiment.

Abstract

The invention provides a decelerator ventilation structure and a decelerator. The decelerator comprises a decelerator shell internally provided with a mounting cavity, and a decelerator end cover arranged at the mounting cavity opening in a sealing mode. The decelerator ventilation structure comprises a cavity formed in the upper wall of the decelerator shell, a first exhausting channel communicating with the mounting cavity and the cavity separately, a second exhausting channel communicating the cavity with the exterior of the decelerator shell, and an oil return channel communicating betweenthe mounting cavity and the cavity. According to the decelerator ventilation structure, an original ventilation valve structure is omitted, the number of decelerator accessories is reduced, oil splashed into the cavity can be automatically fall under gravity, and lubricating oil leaking is effectively prevented.

Description

technical field [0001] The invention relates to the technical field of reducers, in particular to a ventilation structure of a reducer. At the same time, the invention also relates to a reducer with the reducer ventilation structure. Background technique [0002] In a car, the main reducer assembly is the core component of the drive axle and is at the end of the power transmission system. Its basic function is to transmit torque to the half shaft to drive the wheels, increase the torque transmitted from the drive shaft or transmission, and reduce the torque. The rotational speed transmitted by it also has the effect of changing the rotational direction of the torque when the engine is placed vertically. [0003] The general structure of the main reducer of an automobile mainly includes the reducer housing, the gear transmission mechanism located in the installation cavity of the reducer housing, and the reducer end cover installed at the beginning of the reducer housing. W...
