AI Technical Summary
Existing purely mechanical and electromagnetic clutches suffer from slow response, low control precision, susceptibility to overheating and degradation, and short lifespan in high-torque, high-frequency applications. Furthermore, there is friction and wear between rotating parts and stationary actuators.
The friction clutch structure that uses pneumatic braking isolates the rotating parts from the stationary actuator through the design of the thrust ball bearing. It uses air pressure to generate braking force to engage the transmission disc and friction plate, and spring force to separate the parts. The cylinder, piston, bearing and other components are integrated on the rotating shaft to achieve a compact structure.
It achieves precise control, rapid response, compact structure, high integration, good heat dissipation, long service life, and adjustability to meet different needs, and solves the problem of friction and wear between rotating parts and stationary actuators.
