Flexible coupling for rotating shafts - has two similar halves with claws that interlock and shaped elastic damping ring

摘要

The shaft coupling consists of two similar halves with claws in a circular pattern that keep the two mating faces at a prescribed clearance from one another. An elastic damping ring fits in the clearance space. The advantage claimed for the design is that the damping ring is small, compact, of low weight and low cost of manufacture. There is a common inner ring for the two coupling halves (1, 2) with the elastic element held in the region of the claws (13) by two cams (14, 15). The elastic element is shaped in both axial directions to fit into the coupling halves. The inner surfaces of the claws are flat but are cylindrical on the outer section in the form of tooth reinforcing. Alternatively the elastic element can be barrel shaped with curved facing surfaces.
