Abstract
A powertrain system includes a housing that defines a reservoir. A shaft is rotatably disposed in the housing, and the shaft defines a bore. A cap is positioned to seal the reservoir. The cap defines an opening configured to supply lubricant to the shaft. The opening in the cap is positioned proximal the shaft to spray the lubricant into the bore. In one form, the cap has a nozzle, and the nozzle defines the opening configured to supply the lubricant to the shaft. The shaft is configured to rotate about a rotational axis, and the bore extends along the rotational axis of the shaft. The nozzle is aligned with the rotational axis of the shaft to spray the lubricant into the bore in order to lubricate bearings and other parts of the system.
Claims20
A system, comprising:
- a housing defining a reservoir;
- a shaft rotatably disposed in the housing;
- wherein the shaft defines a bore;
- a cap positioned to seal the reservoir;
- wherein the cap defines an opening configured to supply lubricant to the shaft;
- and
- wherein the opening in the cap is positioned proximal the shaft to spray the lubricant into the bore.
A system, comprising:
- a shaft, wherein the shaft is configured to rotate about a rotational axis;
- wherein the shaft defines a bore;
- wherein the bore extends along the rotational axis of the shaft;
- wherein the bore in the shaft is configured to transport lubricant;
- a cap positioned proximal to an end of the shaft;
- wherein the cap has a nozzle;
- and
- wherein the nozzle is aligned with the rotational axis of the shaft to spray the lubricant into the bore.
A method, comprising:
- storing lubricant in a reservoir that is enclosed by a cap that has a nozzle;
- rotating a shaft with a bore;
- and
- spraying the lubricant into the bore of the shaft with the nozzle while the shaft rotates.
