Description
Technical field
The utility model is related to a kind of machine oil pump shaft.
Background technology
Because market is larger to the demand of light truck, the particularly vehicle of low speed high capacity, such engine is to machine oil
The quality requirement of pump is very high.It is not quite similar for from the strict sense, the reliable rational fuel feeding in variant position is even more important.Mesh
Before, traditional machine oil pump shaft, structure is more complicated, is not easy to install, and is difficult fastening.
The content of the invention
The purpose of this utility model is to provide a kind of machine oil pump shaft, solve machine oil pump shaft structure in the prior art it is complicated,
It is difficult the technical problem of fastening.
In order to solve the above-mentioned technical problem the utility model, adopts the following technical scheme that：
A kind of machine oil pump shaft, pump shaft is divided into three sections, including pump cover construction section, interlude and power fastening section, and pump cover is installed
The shaft shoulder is offered between section and interlude, and between power fastening section and interlude, on the end of the power fastening section
External screw thread is provided with, power fastening section offers Woodruff key slots and keyways near one end of interlude；Opened up on the interlude and be equipped with pin
Hole, pin-and-hole is vertical with pump shaft axis.
Woodruff key is placed in the Woodruff key slots and keyways, for fixing power gear, fastening effect is played, power when preventing work
Produced relative rotation between gear and pump shaft.Bearing pin is plugged in pin-and-hole, for fixing internal rotor and pump shaft.
Further improve, a length of 86mm of pump shaft, the radius of Woodruff key slots and keyways is 13mm.
Further improve, the pin-and-hole is 17mm with the distance of pump cover construction section.
Compared with prior art, the beneficial effects of the utility model are：
Woodruff key is placed in the Woodruff key slots and keyways, for fixing power gear, fastening effect is played, power when preventing work
Produced relative rotation between gear and pump shaft.Bearing pin is plugged in pin-and-hole, for fixing internal rotor and pump shaft.It is described in the utility model
Machine oil pump shaft, simple structure is easily installed, and fastening effect is good.

Fig. 1 is the structural representation of machine oil pump shaft described in the utility model.
Fig. 2 is the C-C schematic diagrames of Fig. 1.
Fig. 3 is the D-D schematic diagrames of Fig. 1.
Fig. 4 is the structural representation of lubricating oil pump.
Specific embodiment
To make the purpose of this utility model and technical scheme clearer, below in conjunction with the utility model embodiment to this
The technical scheme of utility model is clearly and completely described.
As Figure 1-4, a kind of machine oil pump shaft, pump shaft is divided into three sections, including pump cover construction section 3, interlude 2 and power are tight
Gu section 1, the shaft shoulder is offered between pump cover construction section 3 and interlude 2, and between power fastening section 1 and interlude 2, described
External screw thread is provided with the end of power fastening section 1, power fastening section offers Woodruff key slots and keyways 11 near one end of interlude；Institute
State to be opened up on interlude 2 and be equipped with pin-and-hole 21, pin-and-hole 21 is vertical with pump shaft axis.
The pump cover construction section 3 is connected by bearing with pump cover 4, and interlude 2 is connected by the bearing pump housing 9.The semicircle
Woodruff key 6 is placed in keyway 11, for fixing power gear, the end of power fastening section 1 is arranged with nut 7, when preventing work
Produced relative rotation between power gear and pump shaft.Bearing pin 8 is plugged in pin-and-hole 21, for fixing internal rotor 5.
In the present embodiment, a length of 86mm of the pump shaft, the radius of Woodruff key slots and keyways is 13mm.
In the present embodiment, the pin-and-hole and the distance of pump cover construction section are 17mm.
Do not done in the utility model illustrate be prior art or be capable of achieving by prior art, Er Qieben
It is only preferable case study on implementation of the present utility model that case is embodied described in utility model, not for limiting this practicality
New practical range.The equivalence changes that i.e. all contents according to present utility model application the scope of the claims are made and modification, should all make
It is technology category of the present utility model.
