Numerical Investigation of the Effects of Structural and Operational Parameters on the Behavior of an Internal Ring Gear Motor and Pump

The dynamic behavior of rotating machinery is crucial for researchers and manufacturers to understand precisely what happens inside the machines during operation. This paper presents a method for predicting the micromotion of the ring gear in an internal gear motor and pump. By solving the Reynolds equation and the motion equation, the ring gear orbit can be obtained. This mathematical model allows for the analysis of the effects of the geometric and operating parameters on the dynamic behavior of the internal gear motor and pump
