主　　题：Cycloid gerotor pump radial force oil groove structure pressure distribution 

摘      要：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 *** the numerical simulations as a basis,an improved oil inlet and outlet groove structure is *** results show that the radial force decreases with the decrease of the outlet pressure and of the rotor *** with the original model,the large-end oil inlet line and pressure line of the new oil groove are *** configuration can effectively weaken the pressure changes inside the gerotor pump and reduce accordingly the radial force on the inner rotor.
