Transmission ratio, improve the revolving speed of lubricating oil pump, to obtain bigger flow, the method is improved most simple, but needs engine producer
It changes together；3) change rotor parameter to improve flow, in general, increase the outer diameter or eccentricity of rotor, and in outer diameter
The number of teeth is reduced in the case where constant, can improve the flow of oil pump, but oil pump radial dimension can change.
It is able to satisfy the adjustment of flow under normal circumstances with upper type, but in oil pump outer dimension, what transmission ratio was unable to adjust
In the case of, above method is with regard to helpless.Even there is client to be distinctly claimed under the premise of the pump housing and revolving speed do not change, it is real
Existing gerotor pump flow increasing.
Summary of the invention
The technical problem to be solved in the present invention is to provide a kind of rotor-type oil pumps of remodeling, are not changing oil pump shape
In the case of, the flow of oil pump can be adjusted.
In order to solve the above-mentioned technical problem, the present invention adopts the following technical scheme: a kind of rotor-type oil pump of remodeling, packet
Driving gear, the pump housing, pump cover, outer rotor, internal rotor, armature spindle are included, the pump housing is equipped with oil inlet and oil outlet, described interior
Rotor be mounted on armature spindle and with armature spindle clearance fit；The both ends of the armature spindle are arranged in the axis of the pump housing and pump cover respectively
Kong Zhong；The driving geared sleeve when sliding tooth wheel rotates, is able to drive outer rotor on the outer peripheral surface of the outer rotor
It is rotated together with internal rotor；The number of teeth of the outer rotor and internal rotor is less than the number of teeth before remodeling；The armature spindle is bias
Axis, and be fixed on the pump housing by a spacer pin.
In one embodiment, the armature spindle is equipped with an axially extending bore, and the pump housing is equipped with one and the axis
To the corresponding blind hole of through-hole, spacer pin one end of spacer pin after the through-hole of armature spindle is inserted into the blind hole of the pump housing
In, armature spindle and the pump housing are fixed.
In one embodiment, the driving gear and the outer rotor are integrally formed.
In one embodiment, consolidated by the way of interference fit between the outer rotor and the driving gear
It is fixed.
The lubricating oil pump flow increasing effect provided in above-mentioned technical proposal is obvious, at low cost, the case where not changing oil pump shape
Under, the flow of oil pump can be adjusted.In the case where the pump housing and constant rotor outer circle, the number of teeth of rotor is reduced, is increased
Eccentricity, the flow increasing of Lai Shixian oil pump, then the new eccentricity of inner and outer rotors and former eccentricity difference are made up with an eccentric shaft, i.e.,
New eccentricity=eccentric shaft+pump housing original eccentricity, makes it to match with pump housing eccentricity, runs well.It is used using the present invention
When remodeling, inner and outer rotors and armature spindle are only needed to change, just can achieve the purpose that oil pump flow increasing, it is ensured that engine, the pump housing and pump
The structure of lid is not necessarily to change, so as to save the cost.
