ABSTRACT:
A long wearing shaft coupling is comprised of metallic male and female members, and a plastic insert. The plastic insert is interference fitted into the female member, and the male member is slip fitted into the insert. The male member is provided with a number of part-circular shaped in transverse cross-section, radially outwardly extending projections which correspond to an equal number of similarly shaped and situated recesses in the insert. The plastic insert transmits the load between the male member and the female member, and is readily replaceable. The projections can be of a slightly smaller radius than the recesses, to allow for misalignments in the shaft. The slip fit nature allows for easy disassembling of the coupling.
