AI Technical Summary
Technical Problem
Existing self-locking methods for brake motors suffer from high maintenance costs, large power losses, and low self-locking efficiency.
Method used
By employing a combination structure of a brake sleeve and a torsion spring, and setting initial friction and gap at different mating sections of the brake sleeve and the torsion spring, rapid self-locking and unlocking are achieved, reducing friction and improving self-locking efficiency.
Benefits of technology
It reduces maintenance and manufacturing costs, decreases power loss, extends the service life of the torsion spring and its surrounding parts, and improves the effectiveness and efficiency of self-locking and unlocking.
