Abstract
A flywheel includes a hub portion concentrically defined around a center of the flywheel. A body portion located peripherally around the hub portion has a driver-side face and a driven-side face. A plurality of passageways in the body portion extend through the flywheel and fluidly connect the driver-side face with the driven-side face. Each of the plurality of passageways is adapted to receive a flow of lubricant spilling onto the driver-side of the body portion when the flywheel is rotating, and to expel lubricant out of the driven-side face of the body portion.
Claims2
A flywheel for transferring a flow of lubricant, comprising:
- a hub portion concentrically defined around a center of the flywheel;
- a body portion disposed peripherally around the hub portion, the body portion having a driver-side face and a driven-side face;
- a plurality of passageways defined in the body portion, the plurality of passageways extending through the flywheel and fluidly connecting the driver-side face with the driven-side face of the body portion;
- a ring-flange concentrically connected to the driver-side face of the body portion;
- and
- a plurality of collectors connected to the flywheel, each collector
- corresponding and being fluidly connected to a respective passageway,
- wherein the plurality of collectors is defined in the driver-side face of the body portion between:
- at least two adjacent projections, each of the at least two projections defined on the driver-side face of the flywheel, each projection extending at least one of radially and tangentially with respect to the flywheel,
- a surface of the ring-flange, and
- a surface of the body portion of the flywheel;
- wherein each of the plurality of passageways is configured to receive a portion of a flow of lubricant spilling onto the driver-side of the body portion into a corresponding collector when the flywheel is rotating, and to direct the flow of lubricant out of the driven-side face of the body portion.
