Abstract

Background technique

The transmission system is an important part of industrial equipment. The dynamic torque on the transmission system is difficult to obtain due to its complex components. Therefore, the design and maintenance of the transmission system has always been a problem for engineering and field personnel.

On the other hand, the setting values of safety couplings are generally set based on experience. It is difficult for designers and users to obtain actual and accurate dynamic torque data on the transmission system as a reference, so safety couplings will be caused. There is a large deviation between the design set value when selecting and the actual real dynamic torque value on the transmission system, and it is difficult for the transmission system and equipment to get real safety protection.

In practice, the traditional mechanical torque-limiting couplings and safety couplings also have the following problems:
