Abstract
The invention provides a steel ball dropped type torque limiter. A plurality of torque limiting parts I and force transmission steel balls are arranged on a sleeve, the force transmission steel balls are meshed with taper holes in a socket so as to transmit torque between the sleeve and the socket, the socket is connected with a flange by a pin, and a precompression spring in the torque limiting part leads the positioning action of a small steel ball to act on the slope of a small shaft so as to provide preset axial force for the force transmission steel ball. When torque is enlarged to the preset torque, the axial counter force of the torque transmitted to the force transmission steel ball is larger than the preset axial force, the force transmission steel ball begins to be separated from the taper hole in the socket, and the small shaft is pushed to move left; when the small steel ball is pushed to the largest outer circular surface of the small shaft, the preset axial force of the small shaft and the force transmission steel ball is zero instantly, the force transmission steel ball is separated from the meshed state completely, and the sleeve and the socket can rotate freely; and in recovery, meshed positions are aligned, and the left end surface of the small shaft is knocked, so that all parts can recover to the original positions to work normally. The torque limiter has a simple structure and accurate overloaded torque, can separate rapidly and completely and recover rapidly and conveniently, is simple to maintain and has long service life.
