AI Technical Summary

Technical Problem

The existing geared motor brake has a complex fastening structure and the bolts are prone to loosening due to vibration, which affects the normal use of the brake.

Method used

The system employs a combination of a limiting disc and a limiting post. By rotating the bolt to the limiting disc and sliding the limiting hole to the limiting post, a circumferential limiting mechanism is formed, ensuring that the nut cannot rotate while allowing the bolt to rotate for threaded connection. Combined with the limiting post and hook chuck, the system improves installation efficiency and torsional rigidity.

Benefits of technology

It simplifies the installation process, improves the smoothness and torsional stiffness of the threaded connection, avoids loosening caused by vibration, enhances the stability of the bolt and nut, and prevents brake damage caused by stress concentration.
