Abstract In order to improve the performances of a cycloid gerotor pump, the
variations of the radial force induced by different rotating speeds and outlet pressures are analyzed numerically. Using the numerical simulations as a basis, an
improved oil inlet and outlet groove structure is proposed. The results show that
the radial force decreases with the decrease of the outlet pressure and of the rotor
speed. Compared with the original model, the large-end oil inlet line and pressure
line of the new oil groove are claw-shaped. This configuration can effectively
weaken the pressure changes inside the gerotor pump and reduce accordingly… More >
