Abstract

The application belongs to the technical field of humanoid service robots, and relates to a robot joint structure and a robot. In the joint structure of the robot, the motor assembly adopts the form of an outer rotor, the rotor is sleeved outside the stator, and the rotor is fixed with a motor shaft. The wave generator in the harmonic reducer is installed on the motor shaft, the flexible spline is driven by the wave generator and meshes with the rigid spline, and the output shaft of the joint is fixed on the flexible spline. When working, the motor shaft drives the wave generator to rotate at high speed, and the wave generator makes the flexible spline produce flexible deformation, the flexible spline and the rigid spline are meshed for transmission, and the power is output through the joint output shaft for low-speed rotation. The output encoder is used to detect the rotation angle of the joint output shaft. The joint structure of the robot is compact, the axial dimension is reduced, the volume and weight are both reduced, and it is suitable for the lightweight and compact layout of the robot.

Description

Technical field [0001] The present application belongs to the technical field of class human service robot, involving a robot joint structure and robot. Background technique [0002] At present, the traditional robot joint structure is an axial docking reducer using the motor assembly, which makes the axial dimension of the robot joint structure, and the space utilization is insufficient, resulting in large volume, weight weight. Inventive content [0003] The purpose of the present application embodiment is to provide a robot joint structure and robot to address the technical problems of existing robot joint structural volume. [0004] The present application embodiment provides a robot joint structure, including: [0005] case; [0006] The motor assembly includes a stator provided in the housing, a rotor outer outer portion of the stator, and a motor shaft that is fixed to the rotor; [0007] The harmonic reducer includes a rigid wheel fixed to the stator, a wave generator mo...
