Abstract

Torque overload protector, including the main shaft end cover shaft, its structure is: the steel ball is embedded in the main shaft groove, the clutch plate is attached to the steel ball, the other side of the clutch plate is attached to the disc spring, and the main shaft sleeve is against the disc type spring, the other side of the main shaft sleeve is screwed into the lock nut to preload the disc spring. The end cover shaft is fixed on the combination sleeve by inner screws. The invention is simple in structure, easy to assemble, and effectively reduces maintenance costs; when overloaded, the action sensitivity is high, and it has the ability to automatically resume work; the torque adjustment range is wide, the use is convenient and accurate, and the complex structure, cumbersome assembly and application in the prior art are solved. Poor technical issues.

Description

technical field [0001] The invention relates to a torque overload protector, which is suitable for torque overload protectors in various transmission systems. Background technique [0002] In many transmission fields, in order to avoid some core functional components being damaged by sudden impact torque overload or causing major safety accidents due to torque overload, torque overload protectors are generally installed in front of the actuators of the transmission system. Generally speaking, torque overload protectors are divided into embedded (torque is transmitted through teeth, teeth, keys or steel balls, etc.) and friction type (torque is transmitted by friction). They all play the role of torque overload protection through overload slipping. Among them, due to material limitations and other factors, the friction type is difficult to guarantee the accuracy after slipping. The use of teeth, teeth and keys in the embedded structure is relatively complicated, and the rep...
