Overrunning clutch for power-driven push rod

Abstract

The invention discloses an overrunning clutch for a power-driven push rod, wherein the overrunning clutch comprises a driving shaft, a driven shaft, a linking sleeve and an internal spline; the linking sleeve and the internal spline are circumferentially and movably connected; the transmission by the driving shaft for the linking sleeve and the internal spline is realized through a first transmission component; the internal spline is connected with an external spline; the transmission by the external spline for the driven shaft is realized through a second transmission component; the first transmission component comprises a transmission steel ball arranged at the end part of the driving shaft; the linking sleeve and the internal spline are respectively provided with an inner hole corresponding to the transmission steel ball; the linking sleeve and the internal spline move axially, thus the transmission steel ball is positioned in the inner hole of the linking sleeve or the inner hole of the internal spline; the bottom end of the transmission steel ball props against the driving shaft; and the top end of the transmission steel ball props against the inner hole wall of the linking sleeve or the inner hole wall of the internal spline for implementing transmission. The separation and combination of the overrunning clutch provided by the invention can be realized stably and reliably, and the rapid release function under a separation state can be realized.

Description

technical field [0001] The invention relates to an overrunning clutch for an electric push rod. Background technique [0002] The overrunning clutch is a basic component that appears with the development of mechatronics products. It is an important component used for power transmission and separation between the prime mover and the working machine or between the driving shaft and the driven shaft inside the machine. It is a device with the function of self-clutching by using the speed change or the transformation of the rotation direction of the main and driven parts. [0003] The State Intellectual Property Office of China announced on March 24, 2010 a utility model patent named clutch with the announcement number CN201428756, which involves a clutch used by an electric push rod, including a thimble, a driven wheel, a transmission disc, a ring gear, and a driving wheel. , The transmission disc is installed in the gear ring, the two parts are coaxial, and the drive disc is ...

AI Technical Summary

Problems solved by technology

[0005] The purpose of the present invention is to provide an overrunning clutch for an electric push rod, which can effectively solve the problems of the existing pin shaft clutch for an electric push rod when the push rod is under heavy load, when the push rod is disengaged, the driving force is large and it is difficult to close
