Embodiment Construction

[0012] The following detailed description will describe the general inventive concept, examples of which are additionally illustrated in the accompanying drawings.

[0013] Figure 1A An isometric view of torsional vibration damper 100 is depicted. The torsional vibration damper 100 includes a hub 102 and a ring 104 that are radially separated by a slot fitted into a rubber insert 106 . Ring 104 includes a radially outer grooved surface 107 configured to receive a serpentine-like belt or the like. The hub 102 includes a central bore 108 having an axial centerline axis 110 . The bore 108 is configured to securely attach to a shaft (not shown) of a rotating system, eg, a rotating shaft of an internal combustion engine. Figure 1B An isometric view of another torsional vibration damper 150 is depicted. Torsional vibration damper 150 includes a ring 152 and a hub 154 that are radially spaced apart by slits fitted with rubber inserts 156 . Ring 152 includes a central bore 158 ...

Abstract

A torsional vibration damper is disclosed, the torsional vibration damper comprises a first member having a radially outer surface including a central recess axially disposed between protrusions; a second member having There is a radially inner surface including a convex portion axially disposed between the recesses and opposite the radially outer surface. The radially outer surface and the radially inner surface are separated by a radial slit, wherein the radial slit defines a cross-sectional profile having an axial center and axial ends, and wherein the radial slit thickness extends from the axial center to the Each axial end increases. Alternatively, the first member includes a central protrusion disposed axially between the recesses, and the second member may comprise a central recess between the protrusions.

Description

technical field [0001] The present invention relates generally to torsional vibration dampers, and more particularly to torsional vibration dampers having a wavy or curvilinear profile, wherein the profile has a thickness that increases in either direction from its center axially toward its periphery. Background technique [0002] Torsional vibration dampers often have a straight or parallel curvilinear profile defined by the innermost diameter of the damper ring and the outermost diameter of the damper hub (outer mass damper), or the outermost diameter of the damper hub. The inner diameter and the outermost diameter of the shock absorber ring (inner mass shock absorber) are defined, which accepts a rubber strip or ring. A profile with straight or parallel curves makes the shock susceptible to high teardrop-type principal strain enhancements at each axial periphery of the profiled rubber. This irregular (or non-uniform) strain enhancement is not desired by design. Furtherm...
