Claims

[Claims for Utility Model Registration] (1) Torque transmission of an electric motor, characterized by providing a frictional coupling part that is disposed between the electric motor and a load and includes a shape memory alloy member whose thickness decreases at high temperatures. Device. (2) A frame consisting of a cylindrical body with a flange formed at the tip and a threaded part on the outer periphery of the opposite end, which is fitted and fixed onto the end of the output shaft of the electric motor, and which is fitted onto the frame and is connected via a friction plate. an annular center member that is pressed against the flange portion, an adjustment nut that presses and fixes the center member via a friction plate, a spacer, and an elastic member, and connects the center member and a load side input side. 2. The torque transmission device for an electric motor according to claim 1, wherein the spacer is made of a shape memory alloy whose thickness decreases when the temperature is high. (3) A frame consisting of a cylindrical body with a flange formed at the tip and a threaded part on the outer periphery of the opposite end, which is fitted and fixed onto the end of the output shaft of the electric motor, and which is fitted onto the frame and is connected via a friction plate. an annular center member that is pressed against the flange portion, an adjustment nut that presses and fixes the center member through a friction plate, a spacer, and an elastic member, and connects the center member and the load-side input shaft. 2. The torque transmission device for an electric motor according to claim 1, wherein the flange portion is made of a shape memory alloy whose thickness decreases when the temperature is high.
