Abstract
A linking arrangement for a shaft and a moving part, such as a fly-wheel, rotating about the same axis includes two coaxial rims fastened to the shaft and moving part, respectively, with radial notches situated on opposed surfaces of the rims that are fixed in contact with one another. The notches provide housings for a set of cylindrical pins so that rotary motion can be transmitted between the shaft and the moving part. Stress-relieving grooves are provided at the bottom portions of the notches so as to permit constant contact between the rims and between the notches and the pins regardless of differential expansion of components of the linking arrangement. A principal application of the linking arrangement is to connect a shaft to a fly-wheel or a shaft to a rotary pump impeller.
