ABSTRACT:
A friction impulse transmission mechanism, which finds application in mechanism engineering, electrical industry and power engineering for impulse driving of mechanisms allow a broad range of regulation of the revolutions, reduced skidding between the flexible elements and the end shaft, prolonged life-time and a constant transmission ratio.
The mechanism comprises a driving shaft and an endshaft enveloped by two flexible elements. According to the invention the driving shaft is a crankshaft with two cranks disposed at a distance of 180 degrees one from the other, and the two flexible elements are each connected at one end to a tightening device. In the zone between the end points where the flexible elements fit the end shaft and the place where the flexible elements are connected to the driving shaft there is connected a device for stretching the flexible elements. In one embodiment, the device for tightening the flexible elements is a spring, and the stretching device represents another spring connected to a mechanism for altering its force. In another embodiment, the device for tightening the flexible elements can represent a rigid element the two ends of which are hinged to the corresponding ends of the flexible elements, a tightening spring being hinged by means of a holder to the middle of the rigid element. The stretching device represents another rigid element the two ends of which are hinged to the flexible elements, the middle of said rigid element being hinged to a regulating rigid stretching device.
