Compared with the prior art, the beneficial effects of the utility model are that:

1. through the fixed orifices, go out oil ring, oil storage tank, inner rotor and lubrication hole of design, solved current rotor formula oil pump in the use, because inner rotor and rotor shaft are at the rotation in-process, inner rotor and inner wall contact friction are too much, and long-term friction can lead to inner rotor surface and inner wall to be connected inseparably enough, can appear the condition of oil leak, leads to the problem that the oil output reduces gradually.

2. Through the solid fixed ring of design, go-between, connecting block, first gear and second gear, be convenient for in the use, solid fixed ring through the design has played the effect that cup joints with the go-between, has played the effect with the inside connecting hole fixed connection who offers of inner rotor through the go-between of design, has solved that inner rotor inside gets into the dust easily and has piled up the inside rotatory difficulty that leads to in the use, the problem that the oil output reduces.
