Speed reducer ventilation device

Abstract

The invention discloses a speed reducer ventilation device. The speed reducer ventilation device comprises a speed reducer. A high-speed shaft is rotatably connected to the left side of the front surface of the speed reducer. A low-speed shaft is rotatably connected to the front surface of the speed reducer and located on the right side of the high-speed shaft. A base is welded to the bottom of the speed reducer. A ventilation device body is connected to the bottom of the right side of the speed reducer through bolts. A First air hole is formed in the position, corresponding to the speed reducer, of the top of the left side of the ventilation device body. A sealing pad is arranged on the surface of the inner wall of the ventilation device body and slidably connected to the bottom of the first air hole. The bottom of the sealing pad communicates with a vent pipe. According to the speed reducer ventilation device, through cooperation of the ventilation device body, the sealing pad, the vent pipe, an air hole, a fixed rod, a first spring, a second spring, a third spring, a first sliding groove, a push rod and air pressure scale marks, the problems that part damage or oil leakage is caused due to the fact that the air pressure value cannot be set and the air pressure value of a speed reducer cannot be adjusted during ventilation when an existing speed reducer ventilation device isin use are solved.

Description

technical field [0001] The invention relates to the technical field of mechanical equipment, in particular to a ventilating device for a reducer. Background technique [0002] Various reduction mechanisms are widely used in the mechanical field. In order to avoid affecting the normal operation of the reducer due to excessive pressure inside the reducer, there is usually a ventilation device on the reducer, whose function is to communicate the inside of the reducer with the outside atmosphere when the gas pressure in the reducer body is too high , so that the internal pressure of the reducer is reduced, and the internal pressure of the reducer is too high to avoid damage to the internal parts of the reducer or oil leakage. The existing reducer ventilation device is always in a state of being connected to the atmosphere during use, so that impurities can easily enter the reducer body, thereby causing damage to the reducer, especially in some places where the environment is re...
