Abstract
The utility model discloses a novel machine oil pump assembly. The bottom of a pump body (3) is provided with two oil tanks (6) which are respectively communicated with an oil inlet (1) and an oil outlet (5) on the pump body (3). The utility model effectively solves the problems of oil leakage and gas leakage, and the sealing performance of the assembly is obviously enhanced. Meanwhile, partial material is saved and manufacturing cost is reduced. The thickness of a guiding part of the pump body, namely the thickness of a rotor shaft hole, is increased, the abrasion of a rotor shaft is decreased and the service life of the rotor shaft is extended.
Description
Technical field
The utility model relates to a kind of new oil pump assembly, particularly a kind of new oil pump assembly that is used for diesel engine, and it mainly is suitable for S1100 type and S1110 diesel engine.
Background technique
Existing engine oil pump assembly, such as the existing engine oil pump assembly of S1100 type and S1110 diesel engine, oil groove is opened on the pump cover, and does the Sealing of the pump cover and the pump housing with paper washer.The problem of ubiquity leakage of oil, gas leakage.Simultaneously, less than normal with the area of contact of rotor shaft because pump housing targeting part is thinner, comparatively serious to the rotor shaft friction in the use, rotor shaft is shorter working life.On the other hand, because oil groove is opened on the pump cover, make the pump cover design comparatively complicated, the material of use is also many.
The model utility content
Technical problem to be solved in the utility model provides a kind of engine oil pump assembly that adopts the new structure of dark oil duct and novel seal mode, is used to overcome the deficiency of above-mentioned existing procucts.
In order to address the above problem, the utility model has adopted following technological scheme.
A kind of new oil pump assembly comprises the pump housing, pump cover and rotor, and its specialization is: offer two oil grooves in described pump housing bottom, they are communicated with filler opening and oil outlet on the pump housing respectively.
Upper-end surface at the pump housing offers circular groove, in this circular groove seal ring is installed.Described seal ring is a rubber seal.
Dark oil duct is set on the pump housing and uses rubber seal that the pump cover and the pump housing are implemented sealing, efficiently solve the problem of leakage of oil, gas leakage, the assembly sealability is able to obvious raising.Save the part material simultaneously, reduced manufacture cost.On the other hand, because oil groove is opened in pump housing bottom, the as many as pump housing of the thickness of pump housing targeting part bottom surface wall thickness and oil groove height sum, therefore after adopting the technical solution of the utility model, pump housing targeting part, the thickness that is rotor shaft hatch increases greatly, and the wearing and tearing that rotor shaft is subjected to reduce thereupon, and prolonged working life.
Description of drawings
Fig. 1 is the utility model embodiment's a structural representation.
Embodiment
Further specify the utility model below in conjunction with embodiment.
As shown in Figure 1, embodiment of the present utility model comprises the pump housing 3, seal ring 4, pump cover 10 and rotor.Its rotor is made up of external rotor 7, internal rotor 8, rotor shaft 9 and rotor pin 2, and external rotor 7 and internal rotor 8 are fixed together by rotor pin 2, and external rotor 7 is enclosed within on the internal rotor 8.
The pump housing 3 bottoms offer two oil grooves 6, and they are communicated with filler opening 1 and oil outlet 5 on the pump housing 3 respectively.The shape of oil groove 6, the degree of depth can be identical with the oil groove on the existing product pump cover.
Be processed with a circular groove in the pump housing 3 upper-end surfaces, and place a ring-shaped rubber seal ring in this circular groove, promptly seal ring 4, and pump cover 10 is sealed on the pump housing 3 upper-end surfaces, plays seal action by pushing this elastic seal ring.The effect of fixing pin 11 is that the pump cover 10 and the pump housing 3 are fixed together.
The oil pressure of this engine oil pump assembly is identical with existing product with flow.
Claims (3)
1, a kind of new oil pump assembly comprises the pump housing (3), pump cover (10) and rotor, it is characterized in that: offer two oil grooves (6) in the described pump housing (3) bottom, they are communicated with filler opening (1) and oil outlet (5) on the pump housing (3) respectively.
2, new oil pump assembly as claimed in claim 1 is characterized in that: the upper-end surface at the pump housing (3) offers circular groove, and seal ring (4) is installed in this circular groove.
3, new oil pump assembly as claimed in claim 1 is characterized in that: described seal ring (4) is a rubber seal.
