凹凸ローラのトラクション特性に及ぼす表面あらさの影響

抄録

This paper presents a study on the effect of the surface roughness on the traction characteristics of concave and convex roller pair contacts. The traction coefficient, oil film formation and oil film temperature in the contact between concave and convex roller pairs of various surface roughnesses were measured under different running conditions by using a concave and convex roller testing machine developed by the authors. On the basis of these results. the effects of specific sliding, contact pressure, roller speed and surface roughness on the traction coefficient, oil film formation and oil film temperature were clarified to a considerable extent.
