Description

technical field [0001] The invention belongs to the field of integrated assembly and testing of a space driving mechanism, and relates to a zero position calibration device for a joint of a large space manipulator. Background technique [0002] The manipulator joint is the core component of the space manipulator. It is the basis for the manipulator to move flexibly and realize various motion functions. It is the key to ensure the manipulator's motion accuracy, connection stiffness, output torque and other functions and performance indicators. The joints provide mechanical and electrical synchronous fast connection, cable transmission and other auxiliary functions for the robotic arm. [0003] The joint has the characteristics of large output torque, high output precision and integration of electromechanical and heat, and is a typical multi-stage planetary reduction mechanism. The joint structure is mainly composed of motor components, joint drive transmission system, resolv...
