Abstract
A brake device of a robot arm utilizes a brake disc whose diameter is much larger than a diameter of a ratchet for increasing a contacting area of the brake disc, so as to generate a greater friction force. The brake device further utilizes a combining pin, a combining plate, and a plurality of guiding pins for transferring a rotating torque to the brake device having a larger diameter, so as to extend a moment arm of the friction force and generate a greater moment, which reduces a prepressing force and extends life of the brake device.
