Investigation on wear and contact fatigue of involute modified gears under minimum quantity lubrication

The wear and contact fatigue of involute modified gears under minimum quantity lubrication were investigated through updated contact path and measurement of the updated profiles. The results indicated that the wear depth of pitch line was not the minimum, there was relative sliding on the pitch line during the wear process and the surface damage had a great influence on it. Continuous wear moves the point of minimum sliding in direction of the...
