International ClassF16D 003/52AbstractA shaft coupling between telescopically overlapped ends of a first shaft and a second shaft including a plurality of inside linear grooves in the first shaft, a plurality of outside linear grooves in the second shaft cooperating with the inside linear grooves in defining a plurality of linear cylindrical passages between the first and the second shafts, and an elastomeric bearing in each of the linear cylindrical passages consisting of a pair of barrel-shaped lugs at opposite ends of an integral beam spring. The barrel-shaped lugs couple together the first and the second shafts for unitary rotation about and for relative linear translation in the direction of a longitudinal centerline of the shaft coupling. The inside and outside grooves bear tangentially against the barrel-shaped lugs. The beam springs maintain substantially zero angular lash between the first and the second shafts by resiliently tipping the barrel-shaped lugs endwise in the linear cylindrical passages.Field of SearchPlural circumferentially spaced elementsExtending between radially overlapping surfaces on driving and driven members Nonmetallic Axially extending torsion bars Extending between radially overlapping surfaces on driving and driven members Plural elements axially spaced along rotational axis COUPLING FACILITATES RELATIVE AXIAL MOTION BETWEEN COUPLED MEMBERS | |
