Abstract

The invention provides a crankshaft-slider assembly, comprising a crankshaft and a slider or a slider group fitted over the crank pin of the crankshaft, characterized in that at least one spacer is mounted on the crank pin, wherein the said at least one spacer is adjoined by the axial extreme side of the slider or the outer axial extreme side of the slider group, wherein the inner hole diameter of the spacer is somewhat larger than the outer diameter of the crank pin, and can play axially after mounting. In accordance with the invention, by selecting the spacers with different thickness based on the actual size of the parts, the problems of high demand to the axial size chain accuracy of the crank pin in the crankshaft-slider assembly and uneasy to control are addressed; the spacers also avoid the contact between the adjacent surfaces which used to produce high-speed friction, and solve the problem of surface ablation.
