The joint is an important core component constituting the robot, especially the mechanical arm, and the overall structure and the motion performance of the joint directly influence the overall operation space, the load capacity and the task execution capacity of the robot. Industrial robot arms in modern industrial scenes need to cooperate with workers to complete related work in a limited working space, so that the robot arm body is required to have large load capacity under the conditions of small self weight and small volume. Meanwhile, the existing requirements also require that the period from design to delivery of the mechanical arm is continuously shortened, and higher requirements are also put forward on the integration speed of the mechanical arm.
The integrated joint is used as an important component of the robot, is generally installed by using one end face at present, can only be installed on one side of a driven device, cannot meet the diversified installation requirements of the robot joint, and limits the design of the robot.
