Further, the both sides of button assembly are connected with front and rear cover by friction shim respectively.
Further, the both sides of the pump housing arrange the sealing between sealing ring realization and front and rear cover.
Further, axle is connected with the inner surface of internal rotor by straight pin.
Further, the front end of axle is connected with rear end cap by spheroid.
Further, described button has z to arrange, z >=2, and mutually stagger between each row 1/z pitch, can nibble mutually with above-mentioned button The ball recess closed also has z to arrange.
Further, button has often arranged n1Individual, ball recess has often arranged n2Individual, n1With n2Relatively prime, and n1> n2。
Further, the most uniform installing hole of outer rotor, the inner surface end of described installing hole is spherical pore, spherical Installing spheroid in hole, the outer surface end of installing hole is screwed hole, installs housing screw in screwed hole, and inner surface end is screwed into compression After screw is allowed to push against spheroid, spheroid protrudes the part of spherical pore and forms button, and this external housing screw contacts with spheroid Part also sets up the ball recess matched with spheroid.
Further, the face that swing link is relative with outer rotor inner surface also sets up the radial section corresponding with button Slot stick for arc.
The invention has the beneficial effects as follows:
Internal messing button pump disclosed in this invention, becomes gear button, and button (spheroid as disclosed in the present invention) is only Needing holes on outer rotor installs, and processing is simple, reduces production cost；Sealing ring is used to solve the movable sealing of axle Problem.
Internal messing button pump disclosed in this invention, the both sides of button assembly are respectively by friction shim with front and rear cover even Connecing, end clearance is little, solves crescent gear pump end face in prior art and reveals big problem, not only can improve the effect of pump Rate, the rated pressure of increase pump, and pump can be made to use in the liquid medium that the viscosity such as sea water, fresh water is relatively low.
Internal messing button pump disclosed in this invention, Z vollyball tooth mutually staggers 1/z pitch, it is ensured that pump output steady Qualitative.
