Driving device suitable for robot leg joint movement

The invention relates to a driving device suitable for robot leg joint movement, which comprises a motor (1), a box body (2), a transmission part (3), a lead screw (4) and a steel sleeve (5), and relates to a robot thigh part which comprises a base joint assembly (7), a thigh assembly (8) and a pin shaft (9). The two sets of lead screws (4), the two sets of motors (1) and the two sets of transmission components (3) are installed on the two connectors of the box body (2) respectively to form the integrated driving device (6). Through the reinforced design of the structure of the driving device,the driving device can provide enough and balanced power for joint movement of robot legs on the premise that the small size and light weight are guaranteed; and the overall rigidity of the legs canbe improved, so that the legs are prevented from deforming when the robot walks, and the accuracy and stability of leg movement of the robot are guaranteed. 本发明涉及一种适用于机器人腿部关节运动的驱动装置，包括电机(1)、箱体(2)、传动部件(3)、丝杠(4)和钢套(5)，涉及的机器人大腿部件
