Abstract: A highorder polynomial gas distribution cam mechanism is investigated theoretically from the viewpoint of thermal elastohydrodynamic lubrication (EHL). First, a cam with a larger base circle radius is employed, which results ...

Abstract: In response to the rapid failure of grease lubrication under low surface speed with zero entraining velocity, a common occurrence in ball screws or cageless rolling element bearings, detailed observations were conducted ...

Abstract: The effect of singlesided and doublesided harmonic surface waviness on the film thickness, pressure, and temperature oscillations in an elastohydrodynamically lubricated eccentrictappet pair has been investigated in relation ...

Abstract: Intermittent motion is a complex process that involves constant speed, deceleration, static stages, and acceleration. Theoretical analysis suggests that shortening the period of intermittent motion can increase the film ...
