SLIDE MEMBER, CRANKSHAFT, AND VARIABLE COMPRESSION RATIO ENGINE

摘要

PROBLEM TO BE SOLVED: To provide a slide member that is rotatable, capable of increasing an antifrictional effect. SOLUTION: Fine recesses 4a and 4b are formed in a slide surface, and directivity of roughness in the slide surface 5 by the recesses are set different between a center part S and other end parts. The slide member is applied to a crankshaft. It is also applied to a crank pin part in a crankshaft for a variable compression engine to which a control mechanism to change the stoke of a piston is connected. COPYRIGHT: (C)2004,JPO&NCIPI
