ELASTIC HYDRODYNAMIC LUBRICATION OF TWO-STEP SINE MOVABLE TOOTH DRIVE
Radial size of two-step sinusoidal movable tooth drive is small, especially suitable for robot arm and other technical fields requiring compacting. However, as the size of the drive decreases, the lubrication state of the meshing pair becomes worse and should be improved. In this paper, the minimum oil film thickness of the elastic hydrodynamic lubrication for the drive system is investigated by determining the suction velocity of the moving pair, the radius of curvature and the load per unit length. The influence of the drive parameters on the minimum oil film thickness is analyzed. Results show that the minimum oil film thickness of the drive system can be increased by increasing the eccentric distance of the eccentric wheel, center distance between the movable tooth and the eccentric wheel, and radius of the movable tooth. The good lubrication state can be achieved by using proper tooth surface processing technology. LIZHONG XU and PEINI YAO 62
