Product name: Robot modular joint Robot module design
shaft at the other end, including an elliptical cam, a rigid wheel a flexible wheel, the elliptical cam rotatingly set on the hollow shaft, the flexible wheel set on the elliptical cam, the rigid wheel set outside the flexible wheel, the outer teeth of the flexible wheel the inner teeth of the rigid wheel engaging. A robot modular joint described in this utility model adopts an integrated fusion design, respectively fixing a motor stator a motor rotor directly to the joint, deleting unnecessary parts such as the motor shell the front rear end caps of the motor of the original motor module, reducing the number of parts of the joint as a whole, so as to reduce the size of the joint reduce the weight of the joint.
