Abstract
For drivingly connecting the external cylindrical surface of an inner machine element to the internal cylindrical surface of an outer machine element, such as a shaft to a pulley, forward and rearward clamping rings are spaced axially apart from one another and have circumferentially spaced aligned bolt holes disposed parallel to the axis of their internal and external cylindrical surfaces. One ring has smooth bolt holes and the other ring has threaded bolt holes, these holes receiving threaded clamping bolts. Mounted in the space between the two clamping rings are pairs of alternately oppositely facing resilient coupling rings of substantially Z-shaped cross-section having bolt holes aligned with the clamping ring bolt holes. Each coupling ring consists of radially-spaced inner and outer annular rims connected at acute angles to the opposite ends of an annular web inclined at an oblique angle to the axis of the cylindrical outer and inner surfaces of these coupling rings. Tightening the clamping bolts urges the clamping rings toward one another, thereby compressing the coupling rings so that their obliquely inclined webs are deformed into more nearly radial positions to the axis o…
