Problems solved by technology

[0002] In the field of robotics, lightweight robotic arms and collaborative robots are gradually occupying the market. As an important part of them, robot joints play an important role. Traditional joints are directly controlled by motors to achieve single-degree-of-freedom motion. And the range of motion is limited, so that the movement of the mechanical arm is limited

Abstract

The invention belongs to the technical field of robots and discloses a three-degree-of-freedom robot joint. The joint includes a first motor, a first planetary gear train, a bevel gear train, a second planetary gear train and a second motor; the output shaft of the first motor is connected with the first planetary gear train, and the first motor is the first planetary gear train Provide power to realize the rotation of the first planetary gear train and the bevel gear train; one end of the bevel gear train is connected to the first planetary gear train, and the other end is connected to the second planetary gear train for the reversing motion of the second planetary gear train; The output shaft of the second motor is connected with the second planetary gear train, the second motor provides power for the second planetary gear train, the second planetary gear train is fixedly connected with a motion device, and the second motor drives the second planetary gear train to rotate, realizing The motion device rotates on its own. The three-degree-of-freedom movement of the joint is realized, and the structure is simple, the precision is high, the cost is low, and the range of motion is wide. Installing it on the mechanical arm can greatly improve the range of motion and running track of the robot.

Description

technical field [0001] The invention belongs to the technical field of robots, and in particular relates to a three-degree-of-freedom robot joint. Background technique [0002] In the field of robotics, lightweight robotic arms and collaborative robots are gradually occupying the market. As an important part of them, robot joints play an important role. Traditional joints are directly controlled by motors to achieve single-degree-of-freedom motion. And the range of motion is limited, so that the motion of the mechanical arm is limited. [0003] Therefore, it is necessary to provide an improved technical solution for the above-mentioned deficiencies in the prior art. Contents of the invention [0004] The purpose of the present invention is to provide a three-degree-of-freedom robot joint to overcome the above defects. The three-degree-of-freedom robot joint in the present invention has a relatively simple structure and a wide range of motion, and it can greatly improve th...
