Description
Technical field
This practical property is related to a kind of Parts of Compressor, more particularly to a kind of lining of connecting rod small end.
Background technology
Lining of connecting rod small end is to pay for the typically company of being fixed in an interference fit first as small end bearing bearing
The bearing of bar microcephaly is sat in hole, and for lining of connecting rod small end of engine loaded in connecting rod small end hole, it supports shaking for engine link
Pendular motion, the fuel feed hole of the lining of connecting rod small end of the prior art cause lubricating oil to be not easily accessed in oil groove, and lubricating oil can
Can enter oil groove after again can spill come, lining of connecting rod small end often rub against can produce heat further increase small end of connecting rod lining
The abrasion of set.
Utility model content
The utility model lies in that providing a kind of lining of connecting rod small end, solve the prior art lining of connecting rod small end into
Oilhole causes lubricating oil to be not easily accessed in oil groove, and lubricating oil can may spill again after oil groove is entered, and connecting rod is small
Head bushing, which often rubs against, can produce the problem of heat increases the abrasion of lining of connecting rod small end.
In view of the above problems, propose following technical scheme：A kind of lining of connecting rod small end, includes lining of connecting rod small end sheet
Body, lining of connecting rod small end inner wall are provided with oil groove and some fuel feed holes, and the fuel feed hole is arranged on oil groove and connects connecting rod
The outer wall of small end bushing, it is characterised in that：Fuel feed hole on lining of connecting rod small end is arranged to small round table-like, the bar company of institute of outer imperial palace
Radiating groove is additionally provided with bar small end bushing, radiating groove is arranged at the outer wall of lining of connecting rod small end and is set relative to the both sides of oil groove
To put, radiating groove is set for one week around the outer wall of lining of connecting rod small end, and the radiating groove is communicated in adjacent two fuel feed holes major part part,
The section of radiating groove is semicircle shape.
The inner wall that the utility model is further arranged to lining of connecting rod small end is arranged to antifriction alloy.
The beneficial effects of the utility model：1 the utility model is the fuel feed hole on lining of connecting rod small end by pervious circular hole
It is arranged to round table-like fuel feed hole so that the lubricating oil of splashing is more easily entered in fuel feed hole so that lubricant effect is more
Significantly, the small round table-like fuel feed hole of outer imperial palace is it is also possible that lubricating oil is not easy to spill out again after entering in oil groove；2 dissipate
Heat channel can shed the heat that lining of connecting rod small end and piston pin friction produce, reduce the aging of lining of connecting rod small end with
And abrasion.
Brief description of the drawings
Fig. 1 is the axial sectional view of the present embodiment lining of connecting rod small end.
Fig. 2 is the present embodiment lining of connecting rod small end radial cross-section.
Figure label implication is as follows：1- lining of connecting rod small end；12- fuel feed holes；13- radiating grooves；14- oil grooves.
Embodiment
With reference to the accompanying drawings and examples, specific embodiment of the present utility model is described in further detail.Below
Embodiment is used to illustrate the utility model, but is not intended to limit the scope of the present invention.
A kind of lining of connecting rod small end as described in Fig. 1-2, lining of connecting rod small end described in the utility model are used to be fitted in
In small end of connecting rod, main function is that a kind of lining of connecting rod small end, is set for reducing the friction between piston pin and small end of connecting rod
There is lining of connecting rod small end 1,1 inner wall of lining of connecting rod small end is provided with oil groove 14 and fuel feed hole 12, and fuel feed hole 12 is arranged at oil groove
On 14 and connection lining of connecting rod small end 1 outer wall, the fuel feed hole 12 on lining of connecting rod small end 1 is arranged to the small round platform of outer imperial palace
Shape, the oil inlet mode in lining of connecting rod small end 1 is largely splash, and this oil inlet mode cannot cause all lubricating oil all
Fuel feed hole 12 can be entered, so fuel feed hole 12 is arranged to small round table-like of outer imperial palace by the utility model, can be with maximum limit
The service efficiency for receiving the lubricating oil that comes of splashing, increasing lubricating oil significantly of degree, the small round platform of outer imperial palace can also be into
The limitation of one step enters the lubricating oil in oil groove 14 so that lubricating oil is thrown out of again when will not work into oil groove 14 to be come, and is wasted
Lubricating oil, is additionally provided with radiating groove 13 in lining of connecting rod small end 1, radiating groove 13 is arranged at the outer wall and phase of lining of connecting rod small end 1
Set for the both sides of oil groove 14, radiating groove 13 is set for one week around the outer wall of lining of connecting rod small end 1, and radiating groove 13 is communicated in phase
Adjacent two fuel feed holes, 12 major part part, the section of radiating groove 13 is semicircle shape, meeting and small end of connecting rod in the motion process of piston pin
Bushing 1 produces friction, and friction will produce heat, the degree of wear of lining of connecting rod small end 1 can be not only increased when temperature is higher
Also can accelerator link small end bushing 1 degree of aging so that the service life of lining of connecting rod small end 1 is significantly smaller, heat dissipation
Groove 13 is communicated in round table-like fuel feed hole 12, and heat can be quickly dispersed into by radiating groove 13 and round table-like fuel feed hole 12
Outside, reduces the temperature in lining of connecting rod small end 1, increases the service life of lining of connecting rod small end 1.
The above is only the preferred embodiment of the utility model, it is noted that for the common skill of the art
For art personnel, on the premise of the utility model technical principle is not departed from, some improvement and modification, above-mentioned vacation can also be made
If these improvements and modifications also should be regarded as the scope of protection of the utility model.
