SUS部材の面圧負荷状態におけるしゅう動特性の評価

抄録

Many component parts of mechanical devices such as bearings, valve sheets,screws, sheets couplings, and gears function together with their counterparts. On the surface of such component parts, bearing force produces rolling and slipping. It is inevitable to generate adhesive wear. In an extreme case, galling occurs on the osculating plane. It is the skin sore caused by friction or abrasion. To avoid such a phenomenon, materials such as aluminum alloy, graphite and titanium garbide are used. Various types of surface coating are also applied. In this paper, the sliding characteristic of stainless steel with a high corrosion resisting property was reviewed under a high load condition. The earlier study of this subject was conducted in the late 80's, where the objective quality characteristics such as load and friction were focused, although larger-the-better SN ratio was used in the study. In this report however, dynamic SN ratio was used to study the function by converting the outputs into the relationship between load and friction. From the results, a more appropriate and detail evaluation of the sliding characteristic under galling condition became possible.
