Description

Coupler torque overload protection structure Technical Field The utility model particularly relates to a coupler torque overload protection structure, and belongs to the technical field of coupler protection. Background The coupling is a part for connecting two different rotating bodies and transmitting torque, and reduces the load of assembly adjustment by absorbing the axial deviation generated between the rotating bodies, and breaks the coupling and releases the connection between the rotating bodies when unexpected overload occurs, thereby protecting the expensive power part and the whole device At present, the existing coupling torque overload protection structure in the market mostly has the defects that the existing coupling torque overload protection structure cannot control the critical point of overload torque according to actual demands in use, so that in practical application, the overload protection structure is too sensitive, frequently triggers a protection mechanism to influence continuous and stable operation of equipment, or the protection structure is slow in reaction and cannot be disconnected in time, so that a power part and the whole device cannot be effectively protected from damage, and the actual demands of the market are difficult to meet. In view of this, we propose a coupling torque overload protection structure.
