AI Technical Summary
In existing robot joint drive systems, the output torque of the motor per unit volume is limited, and the high reduction ratio of the planetary reducer leads to problems such as reduced transmission efficiency, increased backlash, complex structure, and response delay.
The motor assembly with a large radial dimension and the reducer assembly with a small radial dimension are arranged in an integrated structure. The motor assembly is set in the installation space enclosed by the first housing section, and the reducer assembly is set in the installation space enclosed by the second housing section. The motor assembly and reducer assembly are connected by a connecting section to form an integral structure. This ensures that the size of the motor stator and rotor is significantly increased. Combined with the high speed ratio and compact axial structure of the reducer assembly, the radial load capacity is improved.
Without increasing the motor's input power and axial length, the torque output capability and overall performance of the motor are significantly improved, meeting the high torque output requirements of the robot joint, improving the compactness and rigidity of the joint power system, and avoiding an increase in parts and assembly errors.
