A low noise reducer

Abstract

The invention discloses a low-noise speed reducer and relates to the technical field of speed reducers. This kind of low-noise reducer includes a housing, the inner wall of the housing is rotatably connected to the driving gear through the input shaft, the inner wall of the housing is rotatably connected to the rotating shaft through the output shaft, and the side wall of the rotating shaft covers A driven gear is provided. When the reducer is working, lubricating oil with a lower temperature close to the side wall of the housing can be sucked in from the oil inlet pipe, and sprayed out through the oil outlet pipe and oil guide pipe to lubricate the meshing part of the driven gear and the driving gear to ensure deceleration While improving the transmission efficiency of the reducer, the noise of the reducer is lower. At the same time, it can detect whether there are pit defects on the tooth surface of the driven gear and the driving gear, which is convenient for timely maintenance, and can automatically adjust according to the detection situation. The meshing position of the driven gear and the driving gear moves the defective end to avoid meshing with the driving gear, so as to ensure low noise when the reducer is working.

Description

technical field [0001] The invention relates to the technical field of reducers, in particular to a low-noise reducer. Background technique [0002] The reducer plays the role of matching the speed and transmitting torque between the prime mover and the working machine or the actuator. The reducer is a relatively precise machine. The purpose of using it is to reduce the speed and increase the torque. According to the number of transmission stages, it can be divided into single-stage and multi-stage reducers, which are often used as the reduction transmission device between the prime mover and the working machine. The reducer is a kind of gear drive, worm drive, gear- An independent component composed of a worm drive, which is often used as a reduction transmission device between the prime mover and the working machine. It plays the role of matching speed and transmitting torque between prime mover and working machine or actuator, and is widely used in modern machinery. [...

Problems solved by technology

[0004] (1) Viscosity of lubricating oil. Lubricating oil with high viscosity is good for noise reduction, and lubricating oil with low viscosity is good for transmission efficiency. Moreover, the lower the temperature of the lubricating oil, the higher the viscosity and the higher the temperature. The higher the viscosity, the lower the viscosity. However, after the reducer is working, the oil temperature at the gear mesh is higher, which increases the noise of the reducer when it is working;

[0005] (2) When the gear is damaged, when the tooth surface of the gear has a chipping pit defect, the gear transmission accuracy will be reduced, which will increase the noise of the reducer when it is working
