Abstract
A coupling assembly includes a flexible coupling and a first adapter. The flexible coupling defines an opening that extends along a central longitudinal axis between a first coupling end and a second coupling end. The first adapter is arranged to be at least partially received within the opening proximate the first coupling end. The first adapter extends between a first adapter first face and a first adapter second face. The first adapter defines a first adapter post and a first adapter hole. The first adapter post that extends from the first adapter first face. The first adapter hole that extends from the first adapter first face towards the first adapter second face.
Claims18
A power assist system, comprising:
- a shaft provided with a worm that is driven by a motor through a motor shaft;
- and
- a coupling assembly disposed between ends of the shaft having the worm and the motor shaft, the coupling assembly being arranged to provide a mechanical interlock between the shaft having the worm and the motor shaft and facilitate axial compliance along a central longitudinal axis between the shaft having the worm and the motor shaft.
A coupling assembly, comprising:
- a flexible coupling defining an opening that extends along a central longitudinal axis between a first coupling end and a second coupling end;
- a first adapter arranged to be at least partially received within the opening proximate the first coupling end, the first adapter extending between a first adapter first face and a first adapter second face, the first adapter defining:
- a first adapter post that extends away from the first adapter first face, and
- a first adapter hole that extends from the first adapter first face towards the first adapter second face,
- further comprising a second adapter arranged to be at least partially received within the opening proximate the second coupling end, the second adapter extending between a second adapter first face and a second adapter second face, the second adapter defining:
- a second adapter post that extends from the second adapter first face and is arranged to be received within first adapter hole, and
- a second adapter hole that extends from the second adapter first face towards the second adapter second face and is arranged to receive the first adapter first post,
- wherein the first adapter post includes a first planar surface and a first arcuate surface that extends between radial ends of the first planar surface.
