Abstract

The invention relates to a disc type overload protection anti-impact speed reducer. The disc type overload protection anti-impact speed reducer comprises a box body, a worm wheel, an output shaft anda worm. A hollow shaft cavity is formed in the input end of the worm, the outer circumference of the hollow shaft cavity is supported on the box body through a bearing, the outer end of an input shaftis supported on the box body through a bearing, the inner end of the input shaft is coaxially rotationally supported in the hollow shaft cavity through a shaft sleeve or a bearing, multiple parallelcopper friction plates penetrate through the inner wall of the hollow shaft cavity through splines, multiple parallel steel friction plates penetrate through the input shaft through splines, the copper friction plates and the steel friction plates are sequentially attached alternately, an opening of the hollow shaft cavity is in threaded screwed connection with a pressure adjusting nut penetratingthrough the input shaft, and a disc spring abuts against the position between the inner end of the pressure adjusting nut and the steel friction plate or the copper friction plate at the outermost end. The disc type overload protection anti-impact speed reducer is compact in structure and convenient to adjust, protection of input impact and drive overload can be effectively taken into consideration, and the service safe life of the structure is guaranteed.

Description

technical field [0001] The invention relates to a reducer, in particular to a disc type overload protection and anti-shock reducer. Background technique [0002] The traditional worm gear reducer, when there is an impact force at the input end of the worm, will cause great damage to the meshing part of the internal worm gear, and long-term use will affect the service life. When the drive is overloaded, the internal structure cannot be effectively protected, and there are also hidden dangers in the service life. Contents of the invention [0003] The invention provides a disc-type overload protection anti-shock reducer with compact structure, convenient adjustment, effective protection of input shock and drive overload, and ensuring safe service life of the structure. [0004] The technical solution adopted in the present invention is: a disc-type overload protection and anti-shock reducer, including a box body, a worm wheel, an output shaft, and a worm, and is characterize...
