Abstract

A novel overrunning clutch comprising a magnetorheological fluid comprises a gear shaft, a second gear and an input shaft; a groove is inwards formed in the end surface of a first gear at one end of the gear shaft, one end of the input shaft penetrates through a gland and then extends into the groove, a driven disk is mounted at the end, and the gland covers the groove and is mounted on the end surface of the first gear; the second gear is used as an output piece and is fastened at a shaft shoulder in the middle of the input shaft through a flat key and a spring retaining ring for a shaft; anannular excitation coil is mounted on the inner side surface of the groove sealed by the gland and is filled with the magnetorheological fluid; multiple first sealing rings are arranged between the end surface of the first gear and the gland; multiple second sealing rings are arranged between the gland and the input shaft; multiple electric conduction rings are arranged on a transmission shaft ofthe gear shaft; a lead of the excitation coil is connected with an electric brush; and the electric brush is mounted on a gearbox body and makes contact with the electric conduction rings. The overrunning clutch is simple and compact in structure and can perform real-time meshing or separation according to transmission requirements.

Description

technical field [0001] The invention belongs to the technical field of overrunning clutches, and in particular relates to a novel magneto-rheological fluid overrunning clutch. Background technique [0002] The overrunning clutch is a transmission part that is used more often. It is generally used for power transmission and separation between the driving shaft and the driven shaft. It uses the speed change or the change of the rotation direction of the driving and driven parts, and has a self-clutching function. [0003] In the prior art, most of the overrunning clutches are clutches that utilize tooth meshing, ratchet-pawl meshing, or the wedging action of rollers and wedges to transmit motion or torque in one direction, and generally adopt mechanical automatic meshing or disengagement. Therefore, there is a short time difference from separation to transmission engagement, so that the transmission accuracy is low. For the rotation of some precision instruments, ordinary mech...
