Development of 'Roller on Roller' Type Tooth Surface Wear Test Equipment

Abstract

Development of a Roller-on-Roller type test equipment is discussed. The purpose of the equipment is to clarify dominant factors of tooth wear of gears. Radii of a pair of specimen rollers coincide with instantaneous radii of curvatures of gears having specific tooth number, module and pressure angle. Those rollers are actively driven with designed angular velocities to regenerate the sliding velocity at the target condition, so that acquired result can be compared with estimated result of theoretical analysis.
