Abstract

A torque overload protector comprises a main shaft end cover shaft. According to the structure of the torque overload protector, a steel ball is embedded into a main shaft groove, a clutch disc is attached to the steel ball, the other face of the clutch disc is attached to a disk-shaped spring, a main shaft sleeve abuts against the disk-shaped spring, and a lock nut is screwed in the other side of the main shaft sleeve to apply preload to the disk-shaped spring. The end cover shaft is fixed on a combination sleeve through an inner screw. The torque overload protector has the advantages that the structure is simple, assembly is easy, and the maintenance cost is effectively reduced; the action sensitivity is high during overloading, and the automatic working recovery capacity is achieved; the torque regulating range is wide, use is convenient and precise, and the technical problems that in the prior art, the structure is complex, assembly is tedious, and the applicability is poor are solved.

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...
