Abstract
The invention discloses an oil pump rotor which comprises a cylindrical driving spindle, wherein a rotor cam is arranged at the head of the driving spindle, a columnar driving gear is arranged at the tail part of the driving spindle, and a long-rod-shaped positioning inserting rod is arranged at the center of the bottom of the rotor cam. The oil pump rotor has the following advantages: in installation, the positioning inserting rod at the center of the bottom of the rotor cam is fixed in a positioning round hole preset in an oil pump enclosure, and when the oil pump rotor rotates at high speed, the concentricity of the oil pump rotor can be effectively kept, thus effectively improving the sealing performance of the oil pump rotor, and structure is simple, effect is remarkable and practicability is high.
Description
Technical field
The present invention relates to a kind of oil pump device, more precisely, be a kind of oil Pump rotor.
Background technology
The inside of oil pump is typically provided with a pair oil Pump rotor, is used for extruding power oil.When oil Pump rotor high-speed rotation, cam rotor is susceptible to bias and rocks, and particularly after bearing sealing failure, affects the output pressure of oil pump.
Summary of the invention
The present invention mainly solves the technical problem existing for prior art, thus providing a kind of oil Pump rotor.
The above-mentioned technical problem of the present invention is addressed mainly by following technical proposals:
A kind of oil Pump rotor, described oil Pump rotor comprises a columned drive shaft, the head of described drive shaft is provided with a cam rotor, and the afterbody of described drive shaft is provided with the driving gear of a column, and the bottom centre of described cam rotor is provided with the positioning pluging rod of an elongated rod shape.
As preferred embodiment of the present invention, described oil Pump rotor is that converted steel is one-body molded.
The advantage of the oil Pump rotor of the present invention is: during installation, the positioning pluging rod of this cam rotor bottom centre is fixed in positioning round orifice default in oil pump casing, when oil Pump rotor high-speed rotation, can effectively keep the concentricity of oil Pump rotor, it is effectively increased the sealing property of oil Pump rotor, simple in construction, effect is obvious, practical.
Accompanying drawing explanation
In order to be illustrated more clearly that the embodiment of the present invention or technical scheme of the prior art, the accompanying drawing used required in embodiment or description of the prior art will be briefly described below, apparently, accompanying drawing in the following describes is only some embodiments of the present invention, for those of ordinary skill in the art, under the premise not paying creative work, it is also possible to obtain other accompanying drawing according to these accompanying drawings.
Fig. 1 is the perspective view of the oil Pump rotor of the present invention；
Fig. 2 is the perspective view of the oil Pump rotor in Fig. 1, is now another visual angle；
Wherein,
1, oil Pump rotor；2, drive shaft；3, cam rotor；4, gear is driven；5, positioning pluging rod.
Detailed description of the invention
Below in conjunction with accompanying drawing, the preferred embodiments of the present invention are described in detail, so that advantages and features of the invention can be easier to be readily appreciated by one skilled in the art, thus protection scope of the present invention being made apparent clear and definite defining.
As shown in Figure 1 to Figure 2, this oil Pump rotor 1 comprises a columned drive shaft 2, the head of this drive shaft 2 is provided with a cam rotor 3, and the afterbody of this drive shaft 2 is provided with the driving gear 4 of a column, and the bottom centre of this cam rotor 3 is provided with the positioning pluging rod 5 of an elongated rod shape.
This oil Pump rotor is that converted steel is one-body molded.
During installation, the positioning pluging rod 5 of this cam rotor 3 bottom centre is fixed in positioning round orifice default in oil pump casing, when oil Pump rotor 1 high-speed rotation, the concentricity of oil Pump rotor 1 be can effectively keep, the sealing property of oil Pump rotor 1, simple in construction are effectively increased, effect is obvious, practical.
It is not limited to this, any change expected without creative work or replacement, all should be encompassed within protection scope of the present invention.Therefore, protection scope of the present invention should be as the criterion with claims protection defined.
