Abstract
Radial vibration dampers have an inertia member defining an annular channel having (i) a radially facing, open face; (ii) a bottom surface; and (iii) interior, opposing surfaces. The interior, opposing surfaces are each angled outward away from a central transverse plane through the inertia member at an angle in a range from zero degrees to at most 45 degrees. A spring damper member is seated in the annular channel to a selected depth that defines a damper gap between a radial inner surface of the spring damper member and the bottom surface of the annular channel and defines a clearance gap between the shaft and the inertia member. A tuning ratio of the clearance gap to the selected depth is in a range of about 1:1.5 to about 1:0.5.
