Abstract
A self aligning belt drive system comprises a belt drive having a plurality of longitudinally spaced inner lobes each having an alignment groove. The system further comprises at least one pulley comprising a frame configured to rotate about a rotation axis and having a circular outer rim. A plurality of circumferential teeth extend radially and axially of the rim with each tooth being configured to be received between adjacent inner lugs of the drive belt. An alignment flange extends radially between circumferential teeth. The alignment flange is configured to be received in the alignment groove and the alignment flange extends no further radially from the rotational axis than the circumferential teeth. The circumferential teeth, the alignment flange and the alignment groove are configured so that with the alignment flange received in the alignment groove, the drive belt rides on the circumferential teeth.
