WEAR-RESISTANT SLIDE MEMBER AND SLIDE DEVICE USING THE SAME

WIPO Patent Application WO/2005/003522

A1

An object is to ensure that the contact portions of two parts which move in contact and association with each other, for example, a valve bridge and a rocker arm in the valve drive system of a diesel engine, are reduced in wear so as to prolong the life of the parts. A wear-resistant slide member has a wear-resistant member interposed between the contact portions of two parts and held in a recess in a part, which supports it, so as not to fall off, the member being inserted in a state which allows its rotation in the recess and its movement in a direction parallel to the bottom surface, the wear-resistant slide member comprising a first means for chamfering the outer peripheral corners of the bottom surface of the wear-resistant member, a second means for forming the bottom surface of the member in a convex shape having a degree of evenness of 0.05 to 20 μm with the outer periphery warped upward, and/or a third means for causing the surface roughness of the bottom surface, side surface and/or upper surface to be 0.2 μm or less in terms of Ra.
