Abstract
The invention discloses an oil distribution disc of a vane pump. The oil distribution disc comprises an annular disc body, wherein the middle part of the disc body is provided with a bearing mounting hole; the disc body on the outer side of the bearing mounting hole is provided with waist-shaped oil inlet holes which are spaced from one another; waist-shaped oil outlet holes are arranged between the adjacent waist-shaped oil inlet holes; the disc body on the outer side of the waist-shaped oil inlet holes is also provided with a circle of annular groove; a sealing washer is arranged in the annular groove. The end parts of the waist-shaped oil inlet holes are provided with decompression cavities, and higher hydraulic impact is avoided, so the noise of the pump is reduced; the sealing washer is arranged to prevent oil leakage; the disc body is made of alloy powder through one-time molding, so the production efficiency is high, the waste is reduced, the cost is saved, the toughness and the strength are high, the service life is long, and the disc has good application prospect.
Description
Technical field
The invention belongs to Pump Body Parts technical field, be specifically related to a kind of oil distribution plate of vane pump.
Background technique
At present, for the oil distribution casing of vane pump on market, great majority adopt tradition manufacture, and corner material is many, and waste is large, and cost is high, and product efficiency is low, and improper owing to designing, oil distribution casing operationally noise is comparatively large, and sealing effect is poor, the easy spillage oil in edge.
Summary of the invention
Technical problem solved by the invention overcomes in prior art large for the oil distribution casing noise of vane pump, and cost of production is high, and product efficiency is low, and oil distribution casing operationally noise is comparatively large, and sealing effect is poor, the problem of the easy spillage oil in edge.
In order to solve the problems of the technologies described above, the technical solution adopted in the present invention is:
A kind of oil distribution plate of vane pump, comprise the disk body of annular shape, the middle part of described disk body is provided with a bearing mounting hole, it is characterized in that: the disk body outside described bearing mounting hole is provided with the kidney-shaped oil inlet hole be spacedly distributed, and be provided with kidney-shaped oil outlet between adjacent kidney-shaped oil inlet hole, disk body outside described kidney-shaped oil inlet hole is also provided with a ring annular groove, in described annular groove, is placed with seal washer.
Aforesaid a kind of oil distribution plate of vane pump, is characterized in that: the disk body outside described annular groove is also provided with the breach be spacedly distributed, and the outward edge of described seal washer is provided with the projection mated with breach, and described projection is connected in breach.
Aforesaid a kind of oil distribution plate of vane pump, is characterized in that: the quantity of described breach is 6.
Aforesaid a kind of oil distribution plate of vane pump, is characterized in that: the end of described kidney-shaped oil inlet hole is also provided with relief chamber.
Aforesaid a kind of oil distribution plate of vane pump, is characterized in that: described disk body is formed by the disposable pressing mold of alloy powder.
Aforesaid a kind of oil distribution plate of vane pump, is characterized in that: be provided with filter screen in described kidney-shaped oil inlet hole.
The invention has the beneficial effects as follows: the oil distribution casing for vane pump provided by the invention, the end of kidney-shaped oil inlet hole is provided with relief chamber, allows oil har opening and oil inlet hole link up in advance, when oil har opening and oil inlet hole are connected completely, avoid larger hydraulic shock, thus reduce the noise of pump, and be provided with seal washer, prevent leakage of oil, disk body is formed by the disposable pressing mold of alloy powder, product efficiency is high, cut the waste, cost-saving, toughness and intensity larger, long service life, has a good application prospect.
Accompanying drawing explanation
Fig. 1 is the structural representation of oil distribution plate of vane pump of the present invention.
Embodiment
Below in conjunction with Figure of description, the present invention is further illustrated.
As shown in Figure 1, a kind of oil distribution plate of vane pump, comprise the disk body 1 of annular shape, the middle part of described disk body 1 is provided with a bearing mounting hole 2, for installing bearing, disk body 1 outside bearing mounting hole 2 is provided with the kidney-shaped oil inlet hole 3 be spacedly distributed, and be provided with kidney-shaped oil outlet 4 between adjacent kidney-shaped oil inlet hole 3, disk body 1 outside described kidney-shaped oil inlet hole 3 is also provided with a ring annular groove 5, seal washer 6 is placed with in described annular groove 5, the end of kidney-shaped oil inlet hole 3 is also provided with relief chamber 8, in vane pump working procedure, disk body 1 is around bearing rotary, relief chamber 8 can allow oil har opening and kidney-shaped oil inlet hole 3 shift to an earlier date UNICOM, when oil har opening and kidney-shaped oil inlet hole 3 are connected completely, filter screen is provided with in kidney-shaped oil inlet hole 3, avoid larger hydraulic shock, thus reduce the noise of pump, when the oil in vane pump is superfluous, to arrange in oil-feed cylinder by kidney-shaped oil outlet 4, and reusable edible, disk body 1 outside annular groove 5 is also provided with the breach 7 be spacedly distributed, the outward edge of seal washer 6 is provided with the projection mated with breach 7, projection is connected in breach 7, make seal washer 6 in annular groove 5 fixation, seal washer 6 can prevent leakage of oil, the quantity of breach 7 is 6.
Described disk body 1 is formed by the disposable pressing mold of alloy powder, and save material, cost of production is low, and product efficiency is high, and greatly, long service life, has a good application prospect for toughness and intensity.
More than show and describe basic principle of the present invention, major character and advantage.The technician of the industry should understand; the present invention is not restricted to the described embodiments; what describe in above-described embodiment and specification just illustrates principle of the present invention; without departing from the spirit and scope of the present invention; the present invention also has various changes and modifications, and these changes and improvements all fall in the claimed scope of the invention.Application claims protection domain is defined by appending claims and equivalent thereof.
