This paper introduces the resistance network model to calculate the hydrostatic pressure distribution of the oil lubrication film. The effect of geometry and working parameters on the pressure distribution is then analyzed. Among these parameters, the calculation results point out that the radial and axial clearance, as well as the eccentricity of the ring gear, have a significant effect on the hydrostatic pressure distribution.

Effect of oil temperature and viscosity on the ring gear orbit in the internal gear motor and pump is analyzed in this study. The mobility method is used to calculate the ring gear orbit. The mathematical model of oil viscosity and temperature is then integrated into the mobility method. The simulation results point out that the oil temperature and viscosity have great effect on the eccentricity, position angle and minimum oil film thickness.

This paper proposes an approach to determine the instability threshold for the internal gear motors and pumps based on the safe film thickness. By using the mobility method, the maximum eccentricity and the minimum oil lubrication film thickness can be determined, consequently, the minimum speed limit can be retrieved.
