Abstract
A testing apparatus for measuring the friction characteristics between two components in rolling or sliding contact with one another is disclosed herein. The testing apparatus includes a traction surface, a first support structure adapted to support the traction surface while allowing for rotation of the traction surface, and a drive mechanism to rotate the traction surface. The testing apparatus further includes a movable second support structure proximate to the first support structure and adapted to move a test material into contact with the traction surface. An attachment piece is mechanically fixed to the movable second support structure. The attachment piece is constructed to receive and hold the test material relative to the traction surface. The testing apparatus also includes a force measuring device adapted to measure the frictional forces produced between the test material and the traction surface.
