Description
Technical field
This utility model is related to a kind of lubricating oil pump, especially relates to a kind of new self positioning structure lubricating oil pump.
Background technology
At present, domestic used lubricating oil pump is substantially without self positioning structure, occur during assembling assembling inconvenient,
Assembly precision is unstable and situations such as positioning is inaccurate, causes that lubricating oil pump installation site is inaccurate to start it is impossible to function well as
The lubrication of each moving component of machine, inordinate wear and extraordinary noise in each part, affects electromotor normal service life.Cause
This can reduce manufacturing cost it would be highly desirable to design one kind, and reliability of enhancing product performance is so that the life-span of electromotor and economy
It is improved, make to obtain constant, sufficient lubrication fuel pump structure between each parts of engine interior, be presently, there are with overcoming
Lubricating oil pump installation accuracy is unstable, assembly difficulty is big because of difficult point.
Utility model content
In order to overcome above-mentioned existing technological deficiency, the purpose of this utility model is to provide a kind of reduction to install hardly possible
Degree, improves assembly precision, the effectively new self positioning structure lubricating oil pump of the abrasion during the use of reduction lubricating oil pump and noise.
In order to achieve the above object, this utility model is achieved through the following technical solutions：
The technical program is a kind of new self positioning structure lubricating oil pump, including oil pump gear, outer rotor, internal rotor, oil pump
Lid, oil pump casing, pump shaft；Described oil pump cover is fixedly mounted on oil pump casing by attachment screw；Described pump shaft passes through
Oil pump casing and oil pump cover simultaneously pass through corresponding bearing fit；Oil pump gear is fixedly mounted on pump shaft right side；Cover on pump shaft
Equipped with outer rotor and internal rotor；Described internal rotor is passed through needle roller and is coordinated with pump shaft；Described it is uniformly provided with four on oil pump casing
Individual locating piece, on same circumference and the center of circle is concentric with pump shaft for four locating pieces；Described oil pump cover is provided with and machine oil pump case
The groove that four locating pieces of body match.
Compared with prior art, the beneficial effects of the utility model are：This utility model structure is simple, reasonable in design, system
Make required precision not high, make easily, easy to assembly simple, dependable performance, effectively reduces the abrasion during lubricating oil pump uses
And noise.
Brief description
This utility model will be illustrated by example and with reference to the appended drawing, wherein：
Fig. 1 is main structure schematic diagram of the present utility model.
Fig. 2 is the A direction view in Fig. 1.
In figure labelling：Oil pump gear 1, screw 2, outer rotor 3, internal rotor 4, needle roller 5, oil pump cover 6, oil pump casing 7, pump
Axle 8.
Specific embodiment
Below in conjunction with the accompanying drawings, this utility model is described in detail.
In order that the purpose of this utility model, technical scheme and advantage become more apparent, below in conjunction with accompanying drawing and enforcement
Example, is further elaborated to this utility model.It should be appreciated that specific embodiment described herein is only in order to explain
This utility model, is not used to limit this utility model.
Embodiment 1, as shown in Figures 1 and 2, this utility model is a kind of new self positioning structure lubricating oil pump, including oil
Pump gear 1, outer rotor 3, internal rotor 4, oil pump cover 6, oil pump casing 7, pump shaft 8；It is solid that described oil pump cover 6 passes through attachment screw 2
Dingan County is contained on oil pump casing 7；Described pump shaft 8 passes through oil pump casing 7 and oil pump cover 6 and passes through corresponding bearing fit；
Oil pump gear 1 is fixedly mounted on pump shaft 8 right side；Outer rotor 3 and internal rotor 4 are set with pump shaft 8；Described internal rotor 4 passes through
Needle roller 5 is coordinated with pump shaft 8；Described four locating pieces are uniformly provided with oil pump casing 7, four locating pieces are located at same circumference
Go up and the center of circle is concentric with pump shaft 8；Described oil pump cover 6 is provided with the groove matching with 7 four locating pieces of oil pump casing.
Four locating pieces are rectangular block, and on same circumference and the center of circle is concentric with pump shaft 8 for four locating pieces, processing essence
Degree is high, and four locating pieces are matched with oil pump cover 6 upper groove respectively, respectively to 6 liang of side radial positionings of oil pump cover, is formed automatically
Centering and radial positioning, directly load four locating pieces in the groove connecting body during installation, four locating pieces are effectively realized
Position the nimble property it is ensured that assembling.Four rectangle locating pieces of lubricating oil pump, are effectively reduced location area, make simple, precision
Easily ensure, gap between assembling being controlled very well it is ensured that assembly precision, thus improving lubricating oil pump overall precision, reducing lubricating oil pump
Abrasion during use and noise.
The foregoing is only preferred embodiment of the present utility model, not in order to limit this utility model, all this
Any modification, equivalent and improvement made within the spirit of utility model and principle etc., should be included in this utility model
Protection domain within.
