Abstract
Methods and systems are provided for a stabilizing device of a crankshaft. In one example, a method may comprise randomizing a shape of each fin of a plurality of fins and a space between each fin. Randomizing the fins may decrease noise production as a result of airflow generated by the fins.
Claims18
A system, comprising:
- a crankshaft comprising a damper having a plurality of radially extending spokes;
- and
- a stabilizing device comprising a plurality of cooling fins arranged in the damper, wherein the plurality of cooling fins divert airflow around the damper and toward a portion of the crankshaft arranged in an engine.
A stabilizing device, comprising:
- a plurality of fins shaped to fit radially interior to a plurality of radially extending spokes arranged in a damper, the plurality of spokes adapted to be coupled to a portion of a crankshaft arranged outside of an engine, wherein the plurality of fins supplement air flow to a portion of the crankshaft interior to the engine.
A system, comprising:
- an engine comprising a crankshaft, wherein a portion of the crankshaft extends out of the engine, a damper being arranged on the portion of the crankshaft;
- wherein
- a plurality of spokes extend in a radially outward direction from the crankshaft within an inner hub of the damper, and where an elastomeric member is sandwiched between a first surface of the spokes and an inertia ring;
- and
- a stabilizing device pressed against a second surface of the spokes, the second surface being opposite the first surface, and where the stabilizing device comprises a plurality of fins radially extending therefrom, wherein the plurality of fins supplements air flow to a portion of the crankshaft interior to the engine.
