Description
Technical field
The utility model is related to a kind of good crank connecting link assemblies of lubricity.
Background technology
For existing crankshaft connecting rod system in the case where high engine speeds operate, it is the work by centrifugal force to moisten oily mode
With lubricating oil is made to reach on left and right crankshaft-and-connecting-rod, but is difficult to enter into the company of needle bearing and left and right crank and connecting rod
Place is met, due to that cannot lubricate well, it is difficult to meet the crankshaft connecting rod system to run at high speed, temperature rise and insufficient lubrication and lead
Cause the crankshaft-link rod component among engine fragile.For common connecting rod during with crank-pin relative motion, connecting rod is big
Head can inevitably collide or rub with left and right crank, so as to accelerate the abrasion of the major part of connecting rod and left and right crank, reduce
Its service life.
The content of the invention
Shortcoming in for the above-mentioned prior art, it is total that the utility model provides a kind of good crank connecting link of lubricity
Into, can effectively solve needle bearing, the cooling of connecting rod and axis upper connector and lubrication problem, while can solve left crank,
The wear problem of right crank and connecting rod.
In order to achieve the above object, the utility model employs following technical scheme：
The good crank connecting link assembly of a kind of lubricity, including left crank, right crank, crank-pin, connecting rod；The connecting rod it is big
By crank pin connection, the left crank and right crank are matched somebody with somebody respectively with crank-pin both ends interference for head, left crank, right crank
It closes, the connecting rod is provided with rolling between the left crank and right crank between the major part of the connecting rod and the crank-pin
Needle bearing, it is characterised in that：Steel pad is provided between the major part of the left crank, right crank and told connecting rod；The right crank
With the oil leab that lubricates the needle bearing is equipped in crank-pin, and be connected；The right crank axle portion has the first oil
Hole；Steel ball is equipped in the oil leab of the right crank, the steel ball is interference fitted with the oil leab, and left end has footpath
To the oil inlet of setting, right end has the second oilhole.
Further, the first oilhole diameter is less than the oil inlet diameter.
Further, shaft part has dowel hole where the oil inlet.
Further, the microcephaly of the connecting rod has oilhole.
Further, the oil leab in the crank-pin is angularly disposed, and has been disposed radially oil outlet.
The beneficial effects of the utility model include：It disclosure satisfy that the good profit of left and right crank, connecting rod and needle bearing
It is sliding, while meet the lubrication of crank axle portion connector, the major part for further reducing connecting rod is asked in the abrasion of left and right crank
Topic, makes service life of aeroengine longer, reduces rate of breakdown.
Description of the drawings
Fig. 1 is a kind of structure diagram of the good crank connecting link assembly of lubricity of the utility model.
Specific embodiment
The utility model is further described with reference to specific embodiment and attached drawing.
A kind of a kind of good crank connecting link assembly of lubricity as shown in Figure 1 includes：Left crank 1, right crank 5, crank-pin
6th, connecting rod 3；The major part of connecting rod 3, left crank 1, right crank 5 are connected by crank-pin 6, left crank 1 and right crank 5 respectively with crank
6 both ends of pin are interference fitted, and connecting rod 3 is provided between left crank 1 and right crank 5 between the major part of connecting rod 3 and crank-pin 6
Needle bearing 2.In order to reduce the abrasion between the major part both ends of the surface of connecting rod 3 and left crank 1, right crank 5, the present embodiment is in left song
Steel pad 4 is provided between the major part of handle 1, right crank 5 and connecting rod 3.In order to ensure needle bearing 2 and left crank 1, right crank 5 and
The junction lubrication of connecting rod 3 is good, and the oil leab for lubricating the needle bearing 2 is equipped in right crank 5 and crank-pin 6, and
It is connected, wherein the oil leab in crank-pin 6 is angularly disposed.6 middle part of crank-pin is radially provided with oil outlet, directly connects
In needle bearing 2；The small head end of connecting rod 3 has the oilhole of lubrication connecting rod 3 and the bearing of piston junction simultaneously.Right 5 axis of crank
Portion has the component that the first oilhole 501 is used to lubricate right 5 axle portion of crank connection；Steel ball 7 is equipped in the oil leab of right crank 5,
Steel ball 7 is interference fitted with the oil leab in right crank, and for ensureing oil leab right end good seal, left end has radially
The oil inlet 502 of setting, right end have the second oilhole 503.Shaft part where oil inlet 502 has dowel hole, main
It being positioned during for installing, so as to ensure pressure oil passage face oil inlet 502, the pressure loss will not be caused.Second oilhole 503 is led
Lubricating oil is entered by the processing hole of right 5 right end of crank, so as to lubricate the movable part of shaft part connection, wherein steel ball 7
By the processing pore pressure loaded in the oil leab in right crank 5.
During work, pressure oil enters the oil leab in right crank 5 from oil inlet 502, flows out and lubricates through the first oilhole 501
The component of right 5 axle portion of crank connection, since the oil leab in crank-pin 6 is connected with the oil leab in right crank, pressure
Oil can enter in crank-pin 6, then reach needle bearing 2 and left crank 1, right crank 5 by the oil outlet at 6 middle part of crank-pin and connect
The junction of bar 3 reaches good lubricant effect, wherein the diameter of the first oilhole 501 is straight much smaller than oil inlet 502
Footpath, so the too big pressure loss will not be caused.
The technical solution provided above the utility model embodiment is described in detail, used herein specifically
A example is set forth the principle and embodiment of the utility model embodiment, and the explanation of above example is only applicable to help
Assistant solves the principle of the utility model embodiment；Meanwhile for those of ordinary skill in the art, implement according to the utility model
Example, the there will be changes in specific embodiment and application range, in conclusion this specification content should not be construed as
Limitation to the utility model.
