Abstract: An improved link for a chain for use with a sprocket, the link comprising a body having a pair of apertures for receiving connecting pins and a pair of teeth having outside flanks, and inside flanks between the teeth defining a crotch. The improvement includes an effective outer flank angle between a line tangent to the outer flank of the link at 1.5 P and a vertical line intersecting the tangent line of less than or equal to 29 degrees, an effective inner flank angle between a line tangent to the inner flank of the link at 0.5 P and a vertical line intersecting the tangent line of less than or equal to 29 degrees, and a plurality ratios. The links may be assembled into a chain and connected by a plurality of pins.

Abstract: A fastenerless chain snubber is provided that consists of a snubber body, and one or more attachment arms that form positioning blocks. The snubber is positioned in a housing by channel surfaces in the chain housing that locate the positioning blocks of the snubber. The snubber is firmly secured during chain operation by the substantial contact between the snubber attachment arm surfaces opposite the chain cover and the corresponding surface of the installed chain cover.
