A compression ring of a chain sprocket is provided with improved wear characteristics and damping to match various forms of link plates of a chain assembly. The chain assembly includes a plurality of longitudinal link plates hingedly connected by a plurality of pins. The compression ring includes two arrays of compression pads, each array defined by a different profile. Each array of compression pads can be matched to two corresponding groups of link plates. Multiple forms of compression pads and link plate geometries can be accommodated. Compression pad damping force can be tuned by adjusting the width and/or height of the link plates.

Compression ring for chain sprocket

A compression limiter retainer arrangement for a plastic chain guide is provided that minimizes the packaging requirements. The plastic chain guide contains an oblong aperture and a round aperture for mounting to an internal combustion engine. At least one radially inward protruding finger is present at each of the longitudinal ends of the oblong aperture to retain a first compression limiter. Additionally, at least one radially inward protruding finger can be placed proximate to the round aperture to retain an optional second compression limiter. The angular position of the radially inward protruding fingers is defined and limited for optimum chain guide packaging and performance.
