Improvement of the maximum transmission torque of disk-type rotational power transmission mechanism using magnetorheological fluid

Abstract

A disk-type mechanism using magnetorheological fluid that works smoothly and quietly has been proposed as a rotational power transmission mechanism with a torque fuse function for actuator drive. This mechanism has a characteristic that there is a limit value of transmission torque, and torque exceeding this limit value is not transmitted. In this study, the maximum transmission torque was increased by increasing the number of discs, and by using a planetary reduction mechanism consisting of discs that hold a magnetorheological fluid.
