Abstract: The modular development method is usually used for robot electric joint. As the core of the joint, the strength performance of the joint affect directly the reliability and safety of the electric joint and even the whole robot. A method was introduced to verify the strength of the screw through ANSYS software, the structure and force condition of SCARA robot was analyzed, the force situation of the joint screw were simulated during the operation of SCARA robot, and the effectiveness of the joint screw used in the design process of the robot was verified.

Key words: robot, electric joint, screw, strength analysis
