Abstract

PURPOSE:To eliminate an oil reservor and oil groove from a sliding part by forming a solid lubrication phase on the surface of a sliding ceramic part to render the part oilless. CONSTITUTION:A ceramics with a solid lubricant phase is used for an impulse pin 4 and pallet fork 5. For this purpose, ceramics having MoS2, MoSe2, WS2, WSe2 or the like is applicable.
