Overload clutch for speed reducer

Abstract

The invention discloses an overload clutch for a speed reducer. The overload clutch comprises a shaft, wherein the shaft penetrates through a clutch housing; a sleeve shaft is arranged on the shaft ina sleeving manner and jacks the clutch housing; the clutch housing is divided into two parts and is fixed through a screw; a plug is mounted on the clutch housing; the cavity of the clutch housing penetrates through a bearing support shaft; a retainer ring is arranged at the rear end of each of bearings; a space ring is arranged between the bearings; a stop block is arranged between each of the bearings and the space ring; a spring is mounted on the stop block; the stop blocks are mounted between the springs to play a fixing role during the operation process of the bearings; the plug is mounted on the clutch housing to plug a pipe opening not used so as to play a sealing role; the sleeve shaft is mounted on the shaft to reduce abrasion during the operating process of the shaft; the retainer ring is used for limiting; the bearings support the shaft to reduce the friction coefficient during the rotary motion process and ensure the rotary precision; the space ring is used for keeping theaxial distance of the bearings, is simple in processing technology and convenient to mount and dismantle and can prevent the overload clutch from slipping to prolong the service life of an entire fastening system.

Description

technical field [0001] The invention belongs to the technical field of clutches, and in particular relates to an overload clutch for a reducer. Background technique [0002] The general overload clutch is prone to slip phenomenon, and the structure design is relatively complicated. Once the overload clutch in the tensioning device slips, the efficiency of the entire system is greatly reduced, and the safety of the binding device cannot be effectively guaranteed. SUMMARY OF THE INVENTION [0003] In order to overcome the above-mentioned deficiencies of the prior art, the purpose of the present invention is to provide an overload clutch for a reducer, which can effectively prevent the overload clutch from slipping. [0004] In order to achieve the above object, the technical scheme adopted in the present invention is: [0005] An overload clutch for a reducer comprises a shaft, the shaft penetrates a clutch casing, a sleeve shaft is sleeved on the shaft, and withstands the ...
