AI Technical Summary

Technical Problem

Existing geared motor protection devices have poor heat dissipation, causing internal motor components to be damaged due to excessive temperature.

Method used

Design a geared motor protection device that uses an arc-shaped plate to expand through centrifugal force, increasing the contact area with air and driving airflow for automatic heat dissipation. The device also uses a reinforcing core to disperse external pressure, and the arc-shaped plate made of liquid crystal elastic material improves heat absorption and deformation resistance. Combined with a sealing film, it prevents external impurities from entering.

Benefits of technology

It achieves automatic heat dissipation of the geared motor during operation, maintains a moderate temperature, reduces aging of insulation materials and damage to components, improves compressive strength and operational stability, and extends the life of the device.

Abstract

The utility model relates to the technical field of gear motors, and discloses a gear motor protection device which comprises a gear motor body, a connecting shaft is installed at the front end of the gear motor body, a sliding groove is formed in the surface of the connecting shaft, and a fixing plate is fixedly connected into the sliding groove. One end of the fixing plate is fixedly connected with a limiting rod, the tail end of the limiting rod is fixedly connected with the interior of the sliding groove, the surface of the limiting rod is slidably connected with a sliding block, the interior of the sliding groove is rotatably connected with an arc-shaped plate, and the top end of the sliding block is rotatably connected with a connecting plate. According to the gear motor protection device, automatic heat dissipation can be carried out when the gear motor main body runs, so that the gear motor main body can be kept at a moderate temperature when running, the aging of an insulating material, the copper loss of a winding and the damage of parts such as a bearing are reduced, and the effective protection of the gear motor main body is realized.
