摘要: A method of improving wear-resistance and anti-seizing properties of slide surface of machineries, such as outer slide surfaces of piston pins of vehicle engines, wherein slide surfaces of iron or steel base materials of machineries are first processed carburizing, then the carburized surfaces are plated with chromium, and next the chromium-plated surfaces undergo impulses fine peening to produce lubricant-retaining cavities on the slide surfaces, which include fine cavities in the form of depressions in the chromium-plating layer and relatively large cavities produced by exfoliation of the chromium-plating layer.

摘要: A cam drive gear for an engine is described where the distance between the axes of a crankshaft and an idle shaft bearing an idle gear thereon can be made smaller, thereby contributing to a reduction in the size of the engine. In addition, a valve-operating system drive gear for an engine is also described where it is possible to restrain a cam chain from chattering at its portion wrapped around a drive sprocket.
