Pure mechanical friction brake and working method thereof

The invention relates to a pure mechanical friction type brake and a working method thereof. The pure mechanical friction type brake comprises an input shaft disc, a space ring, a copper friction plate, a steel friction plate, a rear end plate, an output shaft, a spring, a spring supporting plate, a bearing, a pin, a cam, a deflector rod and a bearing. Compared with the prior art, the pure mechanical friction type brake is completely composed of mechanical parts, the braking friction force can be set by adjusting the friction plates and the spring, the compression length of the spring is adjusted by extruding the cam through the shifting rod, and therefore the extrusion force between the friction plates is adjusted; and finally, switching of braking and driving of the cam is achieved, so that the basic braking function is achieved, and meanwhile automatic stopping can be achieved in the sudden power failure process to deal with the emergency situation. 本发明涉及一种纯机械式的摩擦式制动器及其工作方法，包括输入轴盘、隔圈、铜摩擦片、钢摩擦片、后端板、输出轴、弹簧、弹
