Abstract
The invention discloses a kind of valve guide bushing, including catheter body, the inside pipe wall of catheter body is divided into epimere, stage casing and hypomere, and epimere and hypomere are helicla flute section, and stage casing is light wall section.The valve guide bushing helps to increase the lubrication between valve and valve guide bushing, so as to improve the abrasion between valve and valve guide bushing or eccentric wear.
Description
Technical field
The present invention relates to valve field, more particularly to a kind of valve guide bushing.
Background technology
In engine work operating, the reciprocating motion of valve mechanism is be unable to do without.Valve guide bushing is right as a guiding mechanism
Valve mechanism is moved back and forth and plays protection and guide effect.
In engine most common failure, there is the failures such as valve guide bushing eccentric wear, valve stem abrasion, in the prior art, valve is led
Pipe uses powdered metallurgical material, and the material has certain self lubricity, abrasion that can to a certain degree between valve guide bushing and valve.
But, powder metallurgy valve guide pipe between valve and valve guide bushing abrasion improve play a part of it is limited, it is impossible to very well
Solve the situation of abrasion and eccentric wear.
The information for being disclosed in the background section is merely intended to increase the understanding to general background of the invention, without answering
In being considered as recognizing or imply in any form that the information structure has been the prior art well known to persons skilled in the art.
The content of the invention
It is an object of the invention to provide a kind of valve guide bushing, help to increase the lubrication between valve and valve guide bushing,
So as to improve the abrasion between valve and valve guide bushing or eccentric wear.
To achieve the above object, the invention provides a kind of valve guide bushing, including catheter body, the inside pipe wall of catheter body
It is divided into epimere, stage casing and hypomere, epimere and hypomere are helicla flute section, and stage casing is light wall section.
Preferably, epimere, stage casing and hypomere respectively account for 1/3rd of catheter body length.
Preferably, helicla flute section pitch is 1-2mm, and groove depth is 0.3-0.5mm.
Compared with prior art, the present invention has the advantages that：By by the inside pipe wall of catheter body be divided into epimere,
Stage casing and hypomere, epimere and hypomere are helicla flute section, and stage casing is light wall section, and when in use, lubricating oil can flow through valve guide bushing
Epimere helicla flute, when whole section of helicla flute is flowed through, can retain a period of time, and the process valve guide bushing plays the work(of storage lubricating oil
Can, as lubricants capacity increases, lubricating oil flows through hypomere helicla flute by the gap of valve and valve guide bushing, and this section of helicla flute is same
Sample plays a part of oil storage with lubrication.Simultaneously as the hypomere is subject to, and gas impact, temperature are of a relatively high, lubricating oil may
Because the influence of temperature produces variation impurity occur, this section of helicla flute plays collection impurity, it is ensured that lubrication and the effect being oriented to.
Brief description of the drawings
Fig. 1 is the structural representation of valve guide bushing of the invention；
Fig. 2 is the use schematic diagram of valve guide bushing of the invention.
Specific embodiment
Below in conjunction with the accompanying drawings, specific embodiment of the invention is described in detail, it is to be understood that guarantor of the invention
Shield scope is not limited by specific embodiment.
Explicitly indicated that unless otherwise other, otherwise in entire disclosure and claims, term " including " or its change
Change such as "comprising" or " including " etc. and will be understood to comprise stated element or part, and do not exclude other units
Part or other parts.
As shown in figure 1, a kind of valve guide bushing 1 (referring to Fig. 2) according to the specific embodiment of the invention, including conduit sheet
Body, the inside pipe wall of catheter body is divided into epimere 11, stage casing 12 and hypomere 13, and epimere 11 and hypomere 13 are helicla flute section, stage casing 12
It is light wall section.
Used as a kind of preferred embodiment, epimere 11, stage casing 12 and hypomere 13 respectively account for 1/3rd of catheter body length.
Used as a kind of preferred embodiment, the pitch of helicla flute section is 1-2mm, and groove depth is 0.3-0.5mm.
The valve guide bushing 1 of such scheme when in use, as shown in Fig. 2 valve guide bushing 1 is assemblied in cylinder head, lead by valve
Valve 2 is installed, the upper, middle and lower section of valve guide bushing 1 plays guide effect to valve, and valve is installed in the upper end of valve guide bushing 1 in pipe 1
Bar oil sealing 3, the effect of seal valve stem 3 is to control lubricating oil from valve 2 and the amount of leakage of seal valve stem 3, and from valve
The lubricating oil revealed at bar oil sealing 3, can flow through the epimere helicla flute of valve guide bushing 1, when whole section of helicla flute is flowed through, can retain one
Section time, the process valve guide bushing plays the function of storage lubricating oil.During valve 2 pumps, lubricated at this
Oil plays lubrication to valve 2 and valve guide bushing 1.As lubricants capacity increases, lubricating oil is by valve 2 and valve guide bushing 1
Gap flow through hypomere helicla flute, this section of helicla flute equally plays a part of oil storage with lubrication.Because the hypomere is rushed by gas
Hit, temperature it is of a relatively high, lubricating oil may due to temperature influence produce variation impurity occur, this section of helicla flute plays collection
Impurity, it is ensured that lubrication and the effect being oriented to.
To sum up, the valve guide bushing 1 of the present embodiment, including catheter body, the inside pipe wall of catheter body is divided into epimere 11, stage casing
12 and hypomere 13, epimere 11 and hypomere 13 are helicla flute section, and stage casing 12 is light wall section, and when in use, lubricating oil can flow through valve
The epimere helicla flute of conduit 1, when whole section of helicla flute is flowed through, can retain a period of time, and the process valve guide bushing plays storage profit
The function of lubricating oil, as lubricants capacity increases, lubricating oil flows through hypomere helicla flute by the gap of valve 2 and valve guide bushing 1, should
Section helicla flute equally plays a part of oil storage with lubrication.Simultaneously as the hypomere is subject to gas impact, temperature of a relatively high, profit
Lubricating oil may produce variation impurity occur due to the influence of temperature, and this section of helicla flute plays collection impurity, it is ensured that lubricates and leads
To effect.
The foregoing description to specific illustrative embodiment of the invention be in order to illustrate and illustration purpose.These descriptions
It is not wishing to limit the invention to disclosed precise forms, and it will be apparent that according to above-mentioned teaching, can be much changed
And change.The purpose of selecting and describing the exemplary embodiment is that explaining that certain principles of the invention and its reality should
With so that those skilled in the art can realize and using a variety of exemplaries of the invention and
A variety of selections and change.The scope of the present invention is intended to be limited by claims and its equivalents.
