Bow spring * coupling introduction

Bow spring*CouplingThe half couplings interact with each other through the elastic ring, and the elastic ring is fixed on the bow spring on the rim of the driven half coupling with the outer surface. In order to make the active half coupling rotate freely relative to the driven half coupling, the elastic ring The stiffness of the ring should be higher than the stiffness of the spring.The elastic ring is made of mixed materials, each layer of the material is concentric with the axis line, and the bow shape under the roller is obtained by connecting a thin layer of resin.In a static state, each roller of the active half coupling is located in the arch of the elastic ring. Because the coupling is reversible, when the active half coupling starts to rotate in any direction, each roller will shift from the center of the arch Small angle, and press to the center position of the arc-shaped driven half coupling, because this is the stable position of the roller.When the transmitted torque value is higher than the nominal torque value, the rollers of the active half coupling will roll on the shaft, and under the centrifugal action of the mass of the elastic ring and the mass of each roller, each roller of the coupling strive Occupying the center position of the elastic ring does not affect this change.
