Elastomer members for a torsional vibration damper, methods of making the same, and torsional vibration dampers having the elastomer members are disclosed. The elastomer members have a first major surface and an opposing second major surface with opposing side joining the first major surface to the second major surface, have a median sagittal plane extending parallel to the first major surface and the second major surface, and a transverse plane perpendicular to the median sagittal plane. In a cross-sectional geometry in a plane bisecting the median sagittal plane and the transverse plane, a thickness of the elastomer member changes along the median sagittal plane in a direction parallel to the transverse plane with a first thickness at both opposing sides and a second thickness at the transverse plane, where the second thickness is greater than the first thicknesses.

1. An elastomer member for a torsional vibration damper comprising: a first major surface and an opposing second major surface with opposing side joining the first major surface and the second major surface;wherein the elastomer member has a median sagittal plane extending parallel to the first major surface and the second major surface, and a transverse plane perpendicular to the median sagittal plane;wherein, in a cross-sectional geometry in a plane bisecting the median sagittal plane and the transverse plane, a thickness of the elastomer member changes along the median sagittal plane in a direction parallel to the transverse plane, a first thickness being at both of opposing sides and a second thickness being generally at the transverse plane;wherein the second thickness is greater than the first thicknesses; andwherein the change between the first thickness and the second thickness varies gradually from the first thickness at a first of the opposing sides to the second thickness as a linear function. 2. The elastomer member of claim 1, wherein the transverse plane is disposed half way between the opposing sides. 3. The elastomer member of claim 1, further comprising a flash of material along the length of each of the first and second major surfaces. 4. The elastomer member of claim 1, further comprising a flash of material along the length of each of the opposing sides. 5. The elastomer member of claim 1, wherein the opposing sides have generally rounded corners. 6. The elastomer member of claim 5, wherein the elastomer member is vertically compression molded thereby having a flash of material along the length of each of the first and second major surfaces. 7. An elastomer member for a torsional vibration damper comprising: a first major surface and an opposing second major surface with opposing side joining the first major surface and the second major surface;wherein the elastomer member has a median sagittal plane extending parallel to the first major surface and the second major surface, and a transverse plane perpendicular to the median sagittal plane;wherein, in a cross-sectional geometry in a plane bisecting the median sagittal plane and the transverse plane, a thickness of the elastomer member changes along the median sagittal plane in a direction parallel to the transverse plane, a first thickness being at both of opposing sides and a second thickness being generally at the transverse plane;wherein the second thickness is greater than the first thicknesses; andwherein each symmetrical half of the elastomer member in cross-section, relative to the transverse plane, is generally trapezoidally-shaped with the larger of the two generally parallel sides aligned with the transverse plane. 8. The elastomer member of claim 7, wherein the change between the first thickness and the second thickness from the first thickness at a first of the opposing sides to the second thickness varies as a non-linear function representing a single curve or more than one curve. 9. A method for making an elastomer member for a torsional vibration damper, the method comprising: providing a vertical compression mold having an upper plate and a lower plate, wherein each of the upper plate and the lower plate include a plurality of spaced apart, elongate channels that are each generally trapezoidally-shaped, when viewed in cross-section transverse to the longitudinal axis, having a larger of two generally parallel sides defining an opening thereof;placing an elastomer material in the lower plate;mating the upper plate to the lower plate to form a plurality of cavities by aligning each one of the channels of the upper plate with one of the channels in the lower plate. 10. The method of claim 9, wherein mating the upper plate to the lower plate includes the application of pressure to disperse the elastomer material within the plurality of cavities. 11. The method of claim 10, further comprising applying heat and pressure to the upper and lower plates to cure the elastomer material. 12. The method of claim 9, further comprising heating the lower plate before placing the elastomer material therein. 13.

A torsional vibration damper comprising: an elastomer member of claim 1 concentric about a hub and compressed against the hub by an inertia member. 15. The torsional vibration damper of claim 14, wherein the first thickness is compressed at least 15% and the second thickness is compressed at most 45%. 16. An elastomer member for a torsional vibration damper comprising: an annular ring of elastomeric material having an elastomer profile, viewed as a cross-section in a plane parallel to an axis of rotation, having a median sagittal plane extending parallel to a first major surface and a second major surface of the elastomer member, and a transverse plane perpendicular to the median sagittal plane, the elastomer profile having a thickness that changes along the median sagittal plane in a direction parallel to the transverse plane with a first thickness at both of the opposing sides and a second thickness at the transverse plane;wherein the second thickness is greater than the first thicknesses; andwherein the change between the first thickness and the second thickness varies gradually from the first thickness at a first of the opposing sides to the second thickness as a linear function. 17. The elastomer member of claim 16, wherein the transverse plane is disposed half way between the opposing sides. 18. The elastomer member of claim 16, wherein the change between the first thickness and the second thickness from the first thickness at a first of the opposing sides to the second thickness varies as a non-linear function representing a single curve or more than one curve.
