TORSIONAL RESONANCE FREQUENCY ADJUSTOR

摘要

Engaging inclined surfaces of an inner ring and an outer ring create wedge action inducing an inward radial force as the rings are forced together longitudinally, holding the adjustor on a rotating body. An inner total arcuate length of each ring is smaller than an outer total arcuate length of a respective target body (inner ring for outer ring, rotating body for inner ring). Arcuate segments of each ring can have inner surfaces with radii of curvature equal to or smaller than that of the target body outer surface, and with a total arcuate length smaller than the circumference of the target body's outer surface.

主权项

1. A torsional frequency adjustor for a rotating body, the torsional frequency adjuster comprising:
a first ring having a first engagement surface parallel to an outer surface of the rotating body, the first engagement surface having a total arcuate length that is smaller than a circumference of the outer surface of the rotating body, the first ring further having a first wedge surface inclined at a first angle with respect to the first surface; a second ring having a second wedge surface corresponding to and selectively engaging the first wedge surface, a total arcuate length of the second wedge surface being smaller than a total arcuate length of the first wedge surface at each corresponding point along a shared longitudinal axis of the first and second rings; an inducer that selectively draws the first wedge surface into engagement with the second wedge surface, thereby inducing an interference fit of the first engagement surface with the outer surface of the rotating body.
