Abstract
An engine accessory belt drive includes a self-aligning pulley assembly including a relatively stationary outer assembly and a universally pivotable inner assembly supported by the outer assembly and able to be locked in position by tightening of a fastener. During alignment of the self-aligning pulley with the belt, the fastener is maintained in the loose position, allowing limited universal pivoting of the rotational axis of the pulley as a result of belt tension forces which act to align the pulley. After the pulley is aligned, the fastener is tightened to fix the rotational axis of the pulley and the inner assembly in the aligned position of the pulley. Features of the inner and outer assemblies of the pulley assembly are also described.
