Description

Technical Field

[0001] The utility model relates to the technical field of drive discs, in particular to a high-temperature resistant drive disc. Background Art

[0002] In industrial automation equipment, the drive disc plays an indispensable and important role. One of its main functions is to efficiently transmit power, accurately and quickly transmitting the powerful power from the power source to the actuator, ensuring that every action of the equipment can be executed accurately and without error, so that the entire equipment can run smoothly. At the same time, the drive disc also has the functions of speed regulation and precise control. By cleverly adjusting the speed of the drive disc and finely controlling its movement, it can adapt to different work needs and process requirements, thereby greatly improving the operating efficiency and performance of the equipment.

[0003] In actual use, as the mechanical equipment keeps running, the drive disc responsible for the power transmission part is affected by pressure and friction, which will cause its own temperature to rise continuously. The existing drive device only uses heat insulation materials or designs heat insulation structures to reduce the impact of high temperature on the drive disc. However, the heat inside the drive disc itself cannot be discharged, so that the connection of the drive disc gradually forms a high-temperature area, which affects the performance and service life of the drive disc and reduces the overall operating efficiency and stability of the equipment. In view of this, the present application proposes a high-temperature resistant drive disc. Utility Model Content
