ABSTRACT:
An assembly for drivably connecting a shaft to a bore includes a member having a bore, wherein a keyway is included in the bore having a semi-circular cross section. A shaft is provided which is configured to have a non-interference fit in the bore, and a surface of the shaft is formed with a keyway having a rectangular cross-section. A unitary component is provided, and is adapted to connect the shaft to the bore of the member and to allow driving forces to be transmitted between the shaft and the bore. The unitary component includes engagement means formed on an inner surface thereof which enables the component to be coupled to the keyway in the shaft. The unitary component also includes an integral key having a semi-circular outer surface corresponding to and adapted to engage the semi-circular keyway formed in the bore.
