Abstract

The invention provides a mechanical four-axis differential device, which includes a transfer case, a closed gear, a casing and four power devices with the same structure, the main rotation center of the transfer case is coaxial with the rotation center of the closed gear, and Located in the center of the four-axis differential transmission device; four power units are evenly arranged on the outer periphery of the mechanical four-axis differential transmission device; the main rotation axes of each power unit are parallel to each other and the main rotation center of the transfer case; Power units Ⅰ, Ⅱ, Ⅲ, and Ⅳ have no direct transmission connection, and one end of them is respectively in transmission connection with the transfer box, and the other end is in transmission connection with the closed gear respectively; the shell plays the role of installation, connection and fixation. The mechanical four-axis differential transmission device provided by the present invention is a transmission device that uses a mechanical structure to realize self-adaptive transfer during single drive and dynamic coupling during four-axis random motion in a complex and uncertain environment, forming power closure, and Accuracy self-calibration is possible.

Description

technical field [0001] The invention belongs to the field of mechanical transmission, in particular to a mechanical four-axis differential device. Background technique [0002] The differential device is a transmission device that utilizes a mechanical structure to realize adaptive transfer during single drive and power coupling during multi-axis random motion under complex and uncertain environments; when driven by a single power source, the device can use one main input The motion is decomposed into multiple sub-output motions with arbitrary speed ratios, and the output torques of each sub-output are equal; when multiple random motions are input, the device can couple them into a single main output motion that has a definite relationship with the input motion, and Synthesize the power of each sub-movement. Therefore, this device has many applications in the field of robotics. On the one hand, it can reduce the number of actuators, and on the other hand, it can avoid the u...
