Abstract

PROBLEM TO BE SOLVED: To smooth switching of low and high springs and to improve characteristic quality by connecting inner and outer rings via elastic bodies and providing a plate spring part abutting elastic bodies when both the rings are displaced by prescribed angles and subsequently pressing and elastically deforming. SOLUTION: An inner ring 1 and an outer ring 2 of concentrically arranged metal are connected via a plurality of rubber-like elastic bodies 3 of an equally distributing shape and a plate spring part 5 is provided in space 4 passing through in a shaft direction between adjacent elastic bodies 3. According to the size of rotary torque for a coupling, the elastic bodies 3 transmit torque and absorb vibration, elastically deforming in a twisting direction, and the elastic bodies 3 do not abut on the plate spring part 5 at the time of low torque and a low spring state is made. When torque becomes larger and reaches a prescribed value, one contact surface 3a of the elastic bodies 3 abuts on one contact surface 5d of the plate spring part 5, and when torque becomes further larger, the elastic bodies 3 press the plate spring part 5 and elastically deforms this plate spring part 5 and a high spring state is made. Therefore, the elastic bodies are prevented from being damaged and switching of a low spring and a high spring can be made smooth.

Next, when the magnitude of the input torque gradually increases and reaches a predetermined value, the elastic body comes into contact with the leaf spring portion, and when the magnitude of the input torque further increases, the elastic body presses the leaf spring portion to elastically deform it. . Therefore, the leaf spring part is added to the torque transmission, and thereafter, the state becomes a high spring state. The amount of elastic deformation of the leaf spring portion gradually decreases as the elastic restoring force increases, and eventually the deformation of the elastic body is stopped in balance with the pressing force of the elastic body. Therefore, after that, the elastic body is not deformed, so that it is possible to prevent the elastic body from being excessively deformed and damaged early. The deformation stop point and the rise of the high spring curve can be arbitrarily set by adjusting the elasticity of the leaf spring portion at the time of manufacturing the coupling, and similarly, switching from the low spring to the high spring is performed. Also, the switching from the high spring to the low spring can be made relatively smooth.
