Description
Technical field
The present invention relates to vane pump technical field, refer in particular to a kind of oil distribution plate of vane pump.
Background technique
Vane pump is made up of rotor, stator, blade and oil distribution casing, oil distribution casing there are oil sucking window and force feed window, the increase of sealed volume forms vacuum from oil suction window oil suction, blade is pressed into gradually, from force feed window out, two friction pairs that oil distribution casing and rotor and blade are formed play conclusive effect to the normal use of vane pump and life-span to oil.At present, the oil distribution casing that market is using is horizontal plane with the surface coordinated of rotor and blade, and has just carried out simple process, and noise is comparatively large in the course of the work, and very easily wear and tear, the working life of vane pump is lower.
Summary of the invention
The matching gap that the object of this invention is to provide a kind of oil distribution casing and rotor and blade is of moderate size and the oil distribution plate of vane pump of long service life.
The technical solution used in the present invention is: a kind of oil distribution plate of vane pump, the center of oil distribution casing is provided with rotor shaft supporting position, the outside of the rotor shaft supporting position on the oil distribution casing side relative with rotor is symmetrically arranged with the arc oil sucking window of two and two symmetrical arc force feed windows, the side of the oil distribution casing relative with rotor is inwardly provided with the lower dent that cross section is camber, the side of the oil distribution casing relative with rotor is made to form the pot bottom-shape face of indent, axial distance between the minimum point of lower dent and peak is 0.002mm-0.005mm, described pot bottom-shape face is provided with the smooth manganese base wearing layer that one deck adopts phosphorating treatment to obtain.
Above-mentioned rotor shaft supporting position is be arranged on the blind hole at left oil distribution casing center or through hole and correspondence to be arranged on through hole on right oil distribution casing.
The line of centres of two above-mentioned arc oil sucking windows perpendicular to two arc force feed windows the line of centres.
The present invention has following outstanding and useful technique effect compared to existing technology: the side that oil distribution casing of the present invention is relative with rotor forms the pot bottom-shape face of indent, the minimum point of lower dent is positioned at the emptying aperture of oil distribution casing center hole along upper, axial distance L between the minimum point of lower dent and peak is 0.002mm-0.005mm, and oil distribution casing surface have employed the wear-resisting phosphorating treatment of manganese base, during work, one deck oil film is formed between the fitting surface of oil distribution casing and rotor and blade, not only ensureing under the prerequisite sealed but also can mutually lubricate, make frictional force minimum, wear and tear also lighter, substantially increase the working life of oil distribution casing.

Embodiment
Below in conjunction with accompanying drawing, with specific embodiment, the invention will be further described, as shown in Fig. 1-6:
A kind of oil distribution plate of vane pump, the center of oil distribution casing (comprising left oil distribution casing and right oil distribution casing) is provided with rotor shaft supporting position, rotor shaft supporting position is be arranged on the blind hole at left oil distribution casing center or through hole 22 (when left oil distribution casing center is blind hole, bearing is arranged in blind hole, when left oil distribution casing center is through hole, bearing is arranged on the left pump housing 6, in the present embodiment, left oil distribution casing center is through hole), and be arranged on the through hole 12 at right oil distribution casing center, the outside of the rotor shaft supporting position on the oil distribution casing side relative with rotor 5 is symmetrically arranged with the arc oil sucking window (oil sucking window 21 of left oil distribution casing and the oil sucking window 11 of right oil distribution casing) of two and two symmetrical arc force feed window (force feed windows 23 of left oil distribution casing, the force feed window 13 of right oil distribution casing), the side of the oil distribution casing relative with rotor 5 is inwardly provided with the lower dent that cross section is camber, the side of the oil distribution casing relative with rotor 5 is made to form the pot bottom-shape face of indent, axial distance L between the minimum point of lower dent and peak is 0.002mm-0.005mm, described pot bottom-shape face is provided with the smooth manganese base wearing layer that one deck adopts phosphorating treatment to obtain.
The cross section of the oil distribution casing side 24 relative with rotor is the pot bottom-shape face of arc, it forms a kind of oil film when coordinating with rotor 6 and blade, axial distance L between the minimum point in pot bottom-shape face and peak is 0.002mm-0.005mm, this gap can when ensureing sealing, make to lubricate between the mutual fitting surface of oil distribution casing and rotor and blade, make running resistance little, wear and tear little, operate steadily reliable, substantially increase the working life of oil distribution casing.
Above-mentioned rotor shaft supporting position is be arranged on the blind hole at left oil distribution casing center or through hole 22 and correspondence to be arranged on through hole 12 on right oil distribution casing, the hole of blind hole or through hole that the minimum point in pot bottom-shape face is positioned at oil distribution casing center is along 31, and the peak in pot bottom-shape face is positioned on the outer (25,15) of the side relative with rotor 5 of oil distribution casing.
The line of centres of above-mentioned two arc oil sucking windows (11,21) perpendicular to two arc force feed windows (13,23) the line of centres.
Although describe embodiments of the present invention by reference to the accompanying drawings; but those skilled in the art can make distortion or the amendment of various equivalence within the scope of the appended claims; as long as be no more than the protection domain described by claim of the present invention, all should within protection scope of the present invention.
