The effects of the geometry and size of the rollers and skew component on traction are experimentally studied on two-roller machines, in which experiments with the point contact are conducted for paraffinic mineral oil under the full EHL conditions. As the radius of a roller in the rolling direction is increased at constant bressure and rolling speed, a gentle decline in the maximum traction coefficient is observed. When the equivalent radius of the roller is equal, it is found that the same traction curve is obtained in both internal and external contacts. A traction curve is sensitive to variation in skew, that is, the initial gradient greatly decreases with a slight increase of skew angle. The simplified Eyring viscous solution already presented shows good agreement with the above observations.
