Abstract: A rotating machinery system provides flexible clutch configuration. In accordance with a first embodiment, a tubular shaft is rotatable about a first axis and has a hollow core, the tubular shaft having a first end and a second end; a second shaft coaxial with the tubular shaft and rotatable about the first axis and located in the hollow core, the second shaft having an input end and a transfer end; and a clutch assembly coupling the first end of the tubular shaft to the transfer end of the second shaft for rotating the tubular shaft responsive to rotation of the second shaft. In accordance with a second embodiment, there is a rotary machinery system for converting rotation about a first axis to rotation about second and third axes.

Abstract: A rotatable machinery system including a washer, the washer including a flange for keeping debris from contacting both rotating and stationary elements. The rotatable machinery system includes a rotatable cross member, a drive shaft coupled to the cross member, a bearing including a bearing housing, and a drive device for rotating the drive shaft. The bearing housing and drive shaft form a circumferential junction. The flange of the washer covers at least a portion of the junction, the washer turning responsive to the drive shaft.
