Abstract

The invention provides a robot power joint with a turbulent flow heat dissipation structure and a robot. The power joint comprises a motor, a joint shell and an end packaging part, the motor is installed in a hollow cavity formed by the joint shell, the end packaging part is located at the end of the motor, a first gap is formed between a rotor and a stator, and a first end gap is formed between afirst end of the rotor and the end packaging part; a plurality of axial airflow channels are formed in the middle of the rotor through spacers; a second gap is formed between the circumferential surface of the stator and the joint shell, a second end gap is formed between the first end of the stator and the end packaging part, and the first end of the stator and the first end of the rotor are thesame end of the motor; the axial airflow channels, the first end gap and the first gap form a communicated first air duct; an axial airflow air duct, the second end gap and the second gap form a communicated second air duct; one end, far away from the first end gap, of the joint shell is provided with a heat dissipation flow channel for communicating the first air duct and the second air duct with the outside.

Description

technical field [0001] The invention relates to the technical field of robots, in particular to a robot power joint and a robot with a spoiler cooling structure. Background technique [0002] The overall humanoid robot has the requirements of light weight, high strength, high explosion, high reliability, etc.; as the power source of the robot, the power joint requires that the torque motor as the core power component must have a high peak torque density, that is, the motor unit weight must output highest possible torque. However, in the state of continuous rotation of the motor rotor, the iron core of the motor will generate iron loss in the alternating magnetic field, copper loss will also occur after the winding is energized, and other types of losses will also occur, which will cause the temperature of the motor to rise . When the temperature rise of the motor exceeds the maximum operating temperature, the motor will be damaged, thereby destroying the stability of the d...
