ABSTRACT:
Method and apparatus for damping the effects of cyclic engine speed variations on the splines of a driving hub and the mating splines of a shaft driven by the hub. A caliper-like retaining mechanism includes a retaining nut threadedly engaging the distal end of the shaft, which distal end is journaled through a splined bore of the driving hub. A shoulder washer is disposed about the shaft proximate the hub shoulder, which shoulder washer is secured to the shaft by the retaining nut. A disc spring urges the shoulder washer into frictional engagement with the hub, which disc spring is retained in a circular groove within the hub. A predetermined preload is exerted by the disc spring on the shoulder washer, which preload is sufficient to overcome the forces which tend to induce rattle between the splines of the shaft and the corresponding splines of the hub.
