摘要： A pin is relatively rotatably fitted into a pin hole formed in an outer link plate of a chain. A plurality of helical grooves are formed on an outer circumferential surface of the pin. A pitch P between adjacent helical grooves in the axial direction is equal to or less than a width in the axial direction of the pin hole of the outer link plate. At least one helical groove is arranged to oppose an arbitrary generatrix on an inner circumferential surface of the pin hole. Also, when a radius of the pin is R and a relative rotation angle with the mating member is θ, a pitch P′ in the circumferential direction between adjacent helical grooves is Rθ or less. Thus, at least one helical groove is arranged to always pass each position in a sliding range between the pin and the pin hole.

摘要： A sealing device for an axle bearing includes a lubricant maintained on sliding contact surfaces, thereby suppressing elevation of torque due to the depletion of grease. A lubricant-adsorbing layer comprises a thickener and a binder. The lubricant comprises a base oil and a thickener. The thickener and the thickener are mutually attracted. A lubricant layer of a prescribed thickness is formed on the lubricant-adsorbing layer. This lubricant layer adheres closely to the lubricant-adsorbing layer making it difficult to separate the lubricant layer from the lubricant-adsorbing layer.

摘要： The electrically motorized pump has a low energy loss because it uses of the shaft and the sleeve made from synthetic resin composition obtained by uniformly dispersing fine powder of RBC or CRBC in a resin. The typical process for the production of a synthetic resin composition for making the sleeve bearing for the pump for use in water includes kneading with a resin the fine powder of RBC or CRBC at a temperature in the neighborhood of the melting point of the resin, and thereby uniformly dispersing the fine powder of RBC or CRBC in the resin. Fibers, such as glass fibers, may be blended with the fine powder of RBC or CRBC and the resin.
摘要翻译：电动泵由于使用轴和由通过将RBC或CRBC的细粉均匀分散在树脂中而获得的合成树脂组合物制成的套筒而具有低能量损失。用于制造用于水的泵的套筒轴承的合成树脂组合物的典型方法包括在树脂的熔点附近的温度下用树脂与RBC或CRBC的细粉末捏合，以及从而将RBC或CRBC的细粉均匀分散在树脂中。纤维如玻璃纤维可以与RBC或CRBC的细粉末和树脂共混。
