Abstract

To simulate various rolling and sliding conditions, a wear testing machine can include a load roller arrangement having at least a first load roller, a second load roller, and a third load roller arranged in a triangular layout. A test roller can be disposed between and in simultaneous contact with the first, second, and third load rollers along at least three points of contact. The load rollers and the test roller can be configured to rotate with respect to each other at a same rotational speed or at different rotational speeds. In an embodiment, the wear testing machine can introduce lubricant to the points of contact between the three load rollers and the test roller.
