Title:
ROTARY ACTUATOR UNIT, AND JOINT UNIT FOR ROBOT OR HEAVY EQUIPMENT PROVIDED WITH SAME
Document Type and Number:
WIPO Patent Application WO/2023/163222
Kind Code:
A1
Abstract:
Provided is a rotary actuator unit employing a simple link structure, and a robot joint unit employing the same. The rotary actuator unit includes a first input portion 10, a second input portion 20, an output link member 30, an intermediate link member 40, an output-side support shaft OP, an intermediate shaft MP, and an input-side support shaft IP, wherein: the first input portion 10 and the second input portion 20 constitute an input-side link mechanism L1 having two degrees of freedom; the intermediate link member 40 and the output link member 30 constitute an output-side link mechanism L2; and a distal end portion of the input-side link mechanism L1 and a proximal end portion of the output-side link mechanism L2 are supported with freedom to rotate about the input-side support shaft IP. A two-dimensional position of the input-side support shaft IP is freely manipulated by controlling a first linear actuator 11 of the first input portion 10 and a second linear actuator 21 of the second input portion 20 to drive the input-side link mechanism L1, and rotation of the output link member 30 about the output shaft OP is used as an output.
