Abstract
An exemplary shaft assembly includes an outer shaft rotatable about an axis, and a shaft insert that provides a conduit for a fluid and blocks the fluid from flowing radially between the shaft insert and the outer shaft relative to the axis. An exemplary shaft assembling method includes positioning a shaft insert within an outer shaft. The shaft insert has a fluid conduit and is configured to block fluid from communicating radially between the shaft insert and the outer shaft.
Claims13
A shaft assembly, comprising:
- an outer shaft rotatable about an axis, the outer shaft a metal or metal alloy;
- and
- a shaft insert that provides a conduit for a fluid and that blocks the fluid from flowing radially between the shaft insert and the outer shaft relative to the axis, the shaft insert a polymer-based material, a composite material, or both,
- wherein a radial path extends from the conduit through the shaft insert and the outer shaft, the radial path to communicate a first amount of the fluid from the conduit,
- wherein the conduit is to communicate a second amount of the fluid along an entire axial length of the conduit.
