Abstract
The utility model provides a light wear resisting oil distribution disc of an oil pump, which is one component of the automobile steering oil pump. The utility model is mainly characterized in that the working surface of the body of the oil distribution disc is provided with a corundum film with very good wear resistance and self lubricity, and the body material is made of aluminum alloy. The utility model has the advantages that the light wear resisting oil distribution disc of an oil pump is light and has a good wear resistance, and the service life can reach zero wear within three hundred thousand kilometers on the condition that the stationary blade is not damaged. The light wear resisting oil distribution disc of an oil pump is a very good oil distribution disc.
Description
Technical field: the utility model relates to the parts in the motor turning oil pump---the improvement of oil distribution casing, the oil pump oil distribution casing that particularly a kind of light weight is wear-resisting.
Background technique: oil distribution casing is a vitals in the motor turning oil pump, and two fastnesses that it and oil pump rotor and blade form are to the normal use and the life-span decisive role of oil pump.The deficiency that existing oil distribution casing is in use deposited is: the one, and quality is heavy, and it is mainly made through casting or powder metallurgy by iron and alloy material, does not meet the requirement of auto parts machinery light; The 2nd, wear no resistance, its wear-resisting property is mainly by its bulk material decision, and present used heavy metal material, do not possess good wear resistance, especially its wear resistance is fixed, to rotor and the blade that the different operating situation requires, can not adjust the fastness that wear resistance is complementary with formation, thereby influence the normal operation and the life-span of oil pump.
Summary of the invention: the purpose of this utility model is to propose the wear-resisting oil pump oil distribution casing that especially can form the fastness that is complementary with rotor and blade of a kind of light weight at the deficiencies in the prior art.
Can realize the purpose of this utility model by following technical proposals, the oil pump oil distribution casing that a kind of light weight is wear-resisting comprises the oil distribution casing body, it is characterized in that being provided with one deck corundum film on the working surface of oil distribution casing body, and the oil distribution casing body is made of light metal material.
The thickness of corundum film is 70-120 μ.
Effect of the present utility model is: 1, light weight meets the requirement of auto parts machinery light.Because after the working surface of oil distribution casing was provided with one deck corundum film, the hardness of its bulk material and intensity just can greatly reduce, thereby can select light metal or original heavy metal of light metal alloy material substitution or heavy metal alloy material.2, wear resistance is good, and this is that the set corundum film of oil distribution casing working surface has excellent abrasion resistance and self lubricity.3, another prior aspect is this corundum film hardness is adjustable, can the material of the rotor of fastness and blade is different does corresponding setting according to forming with oil distribution casing, make it become the very fastness of coupling, thereby greatly prolonged the working life of oil pump.According to surveying and determination, pay under the situation about not being damaged at stator vane,
Life-span of the present utility model can reach 300,000 kilometers does not have wearing and tearing.
The utility model is described in further detail below in conjunction with accompanying drawing.
Description of drawings:
Accompanying drawing 1 is the floor map of preceding oil distribution casing in the utility model;
Accompanying drawing 2 is an A-A place cut-away view in the accompanying drawing 1;
Accompanying drawing 3 is the floor map of back oil distribution casing in the utility model;
Accompanying drawing 4 is a B-B place cut-away view in the accompanying drawing 3.
Embodiment: referring to accompanying drawing 1,2,3,4, oil distribution casing is made of set corundum film 2 on oil distribution casing body 1 and oil distribution casing body 1 working surface.Oil distribution casing body 1 is made of aluminum alloy.The thickness of corundum film 2 is 70-120 μ, and it has excellent abrasion resistance and self lubricity, and this microcellular structure with it is relevant; Its hardness is adjustable, and it can the material of the rotor of fastness and blade is different determines that this can make the fastness of formation reach best coupling according to forming with oil distribution casing.
Claims (2)
1, the oil pump oil distribution casing that a kind of light weight is wear-resisting comprises the oil distribution casing body, it is characterized in that: oil distribution casing body and rotor, the contacted working surface of blade are provided with one deck corundum film wearing layer, and the oil distribution casing body is made of aluminum alloy material.
2, by the wear-resisting oil pump oil distribution casing of the described light weight of claim 1, it is characterized in that: the thickness of corundum film wearing layer is 70-120 μ.
