DEVICE FOR PREVENTING THERMAL DEFORMATION

摘要

A mechanism for driving a shaft comprises a frame on which a driving motor is mounted that is operatively coupled to the shaft through pulleys and belts. A device for preventing the frame from being thermally deformed includes a heat collecting plate having a cavity mounted between the driving motor and the frame, a radiator connected to the cavity of the heat collecting plate through circulation pipes, and working fluid, such as Freon, charged in the cavity, the radiator, and the pipes. The heat generated in the driving motor is transmitted by the working fluid to the radiator without being transmitted to the frame, which is prevented from being thermally deformed.
