Abstract

The invention provides a reliable joint control-driven component and a control method thereof. The reliable joint control-driven component is composed of a redundancy driving device and a control device, wherein the redundancy driving device comprises a drive motor A, a drive motor B, a gear train, a motor frame, a shell and a planetary gearbox; and the control device is composed of a casing, a central control unit, a power module, a wire connecting terminal, a motor driver and a power adapter. In the reliable joint control-driven component, a gear train structure with a torque limiter is integrated with the planetary gearbox, and a mode of increasing a redundancy driver is used; therefore, the component of the invention is a novel joint redundancy driving component which has a backup function and the advantages of low power consumption, high torque, high accuracy, good mechanical property, low vibration and the like.

Description

technical field [0001] The invention belongs to the technical field of machinery, and in particular relates to a reliability joint control drive assembly and a control method thereof. Background technique [0002] With the advancement of technology, more and more mechanical devices are used in fields such as aerospace, medical and nuclear industries. In the space environment, if the kinematic joint fails, the entire mechanical device may not be able to complete the task, and the operator is difficult to access, the consequences are very serious. The joint motion of the mechanical device is realized by the work of the joint driver, so it is of great significance to improve the reliability of the joint driver. [0003] According to the mechanical design theory, the degrees of freedom of the mechanism should be equal to the number of drives. For single-joint mechanisms, such as the drive assembly developed by RUAG in Switzerland for adjusting the angle of the solar wing sail ...
