IMPACT DEVICE Russian patent published in 1994 - IPC

FIELD: pulsating geared motor with heavy torques on output shaft in load-hoisting and traction mechanisms, nut drivers and perforators. SUBSTANCE: end of striker facing the working tool has a tapered chamfer with a plain or serrated surface. The device incorporates an adapter installed coaxially on the end of working tool with a provision for longitudinal movement. One end of said adapter facing the striker has a matching tapered chamfer. There also is a flexible member for pressing the other end of adapter against the working tool. Motor may be made as a solenoid whose winding is cut into the circuit via a diode. In this case the striker functions as the motor shaft and at least one of its ends is connected to a spring. Motor may be made as a mechanism for rotary-translational action connected to the striker. EFFECT: higher efficiency. 3 cl, 3 dwg
