Title:
JOINT TORQUE SENSOR AND ROBOT JOINT UNIT INCLUDING SAME
Document Type and Number:
WIPO Patent Application WO/2019/083302
Kind Code:
A1
Abstract:
The present invention is to provide a robot joint unit which can measure a torque applied to a robot joint by a reaction method, reduce a mutual interference phenomenon occurring in a joint torque sensor due to vibration of a reducer, and increase a torque measurement accuracy of a joint, and a joint torque sensor provided in the same. A robot joint unit according to the present invention comprises: a base part; a driving part which includes a stator supported by the base part and a rotor rotatably supported by the stator and thus provides an input torque; a reducer which receives an input torque from the driving part and reduces speed to generate a driving torque; an output link which receives the driving torque from the reducer and rotates; and a joint torque sensor which is arranged on the base part to sense a reaction torque applied to the reducer from the output link, and supports the stator.
