The utility model discloses an advantage: the utility model discloses simple structure, processing convenience, long service life, product move stably, economic benefits is good, operation safe and reliable, and the axis body is protected to this protective sheath, and messenger's axle sleeve can't direct contact with the axis body to reduce the wearing and tearing of axle sleeve, the protective sheath is behind thermal treatment, and the roughness on surface is than lower, thereby the frictional force between messenger's axle sleeve and the protective sheath is less, thereby reduces wearing and tearing volume between them, has guaranteed that the axis body has longer life.
Description
Technical field
This utility model is related to oil pump component technology field, and in particular to a kind of oil pump shaft.
Background technology
Lubricating oil pump be for make engine oil pressure raise and ensure certain oil mass to each friction surface force fuel feeding device,
Fuel pump structure form can be divided into two class of gear type and rotator type, and gear type oil pump is divided into internal-gear type and external gear again
Formula, is reliable operation the characteristics of the latter is called gear-type oil pump, gear type oil pump typically, simple structure, it is easily manufactured and
Pump oil pressure is higher, so being used widely, general gear type oil pump includes pump case, driving gear and driven gear,
Driving gear is connected with external power supply by final drive shaft, makes machine oil pump work with transmitting torque, and in prior art, oil pump is passed
Moving axis is mostly to be integrally machined and forms, and its difficulty of processing is larger, and production takes time and effort, and production cost is higher.
Utility model content
The purpose of this utility model is the defect and deficiency for prior art, there is provided a kind of processing is simple, use the longevity
The longer oil pump shaft of life.
For achieving the above object, the technical solution adopted in the utility model is：A kind of oil pump shaft, including axis body, the axle
The front end of body is raised connecting portion, is uniform-distribution with a circle engaging tooth, the root of the engaging tooth on the outer wall of the connecting portion
Portion fixedly mounts a circle spacing block set, offers the oil storage hole through connecting portion inside and outside wall, the axle on the connecting portion
The outer wall of body is provided with the louvre uniformly opened up for a week around axis body, also fixedly mounts a circle and protect on the outer wall of the axis body
Sheath.
Further, the engaging tooth extends to be formed along the axis direction of axis body, and is integrally formed with axis body.
Further, the spacing block set is integrally formed with connecting portion.
Further, a diameter of 1-3mm of the oil storage hole.
Further, a diameter of 2-5mm of the louvre, depth is 4-6mm, and quantity is at least 6.
Further, the protective case is integrally formed with axis body.
After said structure, this utility model has the beneficial effect that：
（1）This utility model simple structure, easy to process, long service life, product are stable, good in economic efficiency, fortune
Row is safe and reliable, and axis body is protected by the protective case, make axle sleeve and axis body cannot directly contact, so as to reduce the mill of axle sleeve
Damage, after heat treatment, the roughness ratio on surface is relatively low for protective case so that the frictional force between axle sleeve and protective case compared with
It is little, so as to reduce both wear extenies, it is ensured that axis body has longer service life.
（2）The oil storage hole that this utility model is adopted, first can add lubricating oil in oil storage hole, be operated in axis body
When, lubricating oil from oil storage hole to axis body outside flow out, the lubricating oil of outflow can be lubricated to connecting portion, so that axis body reaches
The effect of lubrication.
（3）The heat that oil pump shaft outer wall is produced can be dispersed into by the louvre that this utility model is adopted from louvre
In axis body, make axis body internal/external heating uniform, it is ensured that the practical stability of oil pump shaft.
Description of the drawings
