Abstract
Methods and systems are provided for a crankshaft damper cover for a crankshaft damper of a crankshaft in an engine. In one example, a crankshaft damper cover shaped to fit within a cavity of a crankshaft damper and including an inset and an annular ring embedded within the inset, where the annular ring includes tabs adapted to mate with an inner surface of the crankshaft damper. As one example, the inset may be comprised of a damping material, such as plastic or foam.
Claims20
A crankshaft damper cover, comprising:
- an annular ring including a plurality of tabs arranged around a circumference of a planar portion of the annular ring, the annular ring adapted to couple to an inner circumferential surface of an inner shell of a crankshaft damper;
- and
- an inset molded around the annular ring and shaped to fit within a cavity formed by the inner shell.
A crankshaft damper, comprising:
- an inner shell including a cavity depressed from an exposed surface of the inner shell and formed by an inner surface of the inner shell;
- a cover including an inset comprised of a damping material, shaped to fit within the cavity, and formed around an annular ring comprising a plurality of tabs that extend from within the inset to an exterior of the inset and mate with the inner surface.
A crankshaft damper, comprising:
- an inner shell including a hub end adapted to directly couple to a crankshaft and an exposed end including a cavity depressed from an exposed surface of the inner shell and formed by an inner surface of the inner shell, where the crankshaft damper includes a central axis;
- a damping element surrounding the inner shell and surrounded by an outer shell of the crankshaft damper;
- and
- a cover including an inset comprised of a damping material, shaped to fit within the cavity, and formed around an annular ring comprising a plurality of tabs positioned around a circumference of the annular ring, where each tab of the plurality of tabs includes a first end directly coupled to a planar portion of the annular ring and positioned within an interior of the inset and a second end bent outward from the planar surface and toward the exposed surface of the inner shell and positioned exterior to the interior of the inset, where the second end mates with a first planar surface of the inner surface of the inner shell, where the first planar surface is parallel to the central axis.
