Description
Technical field
This practicality belongs to engine art, is specifically related to a kind of connecting rod.
Background technique
At present, connecting rod mostly adopts full supporting structure, and material is high-strength ductile cast iron.Its structural feature is that main journal bearing shell steel backing is slightly thicker than connecting rod bearing shell, and inner surface of bearing bush is processed with oil groove, and steel backing is milled with grooving and this oil groove connects, in order to supply oil lubrication to connecting rod bearing shell.In order to prevent the bent axle axial float, taked flange thrust washer structure, be arranged near on last one main bearing of flywheel.The turnup structure of flanger bearing liner is actually two annular thrusting plates that are comprised of steel backing and antifriction alloy layer, is furnished with oil groove on the antifriction alloy layer, and is lubricated to improve.
The shortcoming of prior art is: very inconvenient in the time of for the connecting rod lubricating oil filling, and oily incomplete situation can appear moistening.
The model utility content
Technical problem to be solved in the utility model is to provide a kind of convenient interpolation lubricant oil, and the connecting rod that linkage mechanism is lubricated comprehensively.
the technical solution of the utility model is as follows: comprise left crank and right crank, be respectively arranged with on described left crank and right crank over against crank pin hole, be equipped with same crank pin in the crank pin hole of the crank pin hole of described left crank and right crank, be respectively installed with left crankshaft bearing and right crankshaft bearing on described left crank and right crank, the inboard of described left crankshaft bearing and right crankshaft bearing is close to two ends, described crank pin left and right respectively, be set with connecting rod on described crank pin, described connecting rod is between described left crank and right crank, described connecting rod is connected with piston by piston pin hole, its key is: be provided with the first oil leab in described right crank, be provided with the second oil leab in described crank pin, described the second oil leab two-port is respectively over against described left crankshaft bearing and right crankshaft bearing, described the first oil leab and the second oil leab connect by the 3rd oil leab.
Only need during lubricating oil filling thus pour lubricant oil into first oil leab, lubricant oil flows to the second oil leab through the 3rd oil leab, arriving bearing through the second oil leab, can add very easily lubricant oil like this.
Described the first oil leab is horizontally set in described right crank, described the second oil leab is set in described crank pin vertically, one one of described the 3rd oil leab is arranged on described right crank, another one is arranged on described crank pin, and the 3rd oil leab is obliquely installed, the oil leab of installing can comprehensively add lubricant oil to for whole connecting rod thus, and is thoroughly lubricated.
One throw of eccentric is arranged between the axis of described piston and piston pin hole, connecting rod is connected with piston by piston pin hole, piston passes to connecting rod with the gas pressure that bears like this, the other end of connecting rod is connected with bent axle by the connecting rod neck axle simultaneously, and the gas pressure that piston is born by the effect of connecting rod makes the to-and-fro motion of piston change rotatablely moving of bent axle into, and the connecting rod pivot angle when making motion reduces, the side pressure that piston bears reduces, wearing and tearing reduce, and the life-span increases, and mechanical efficiency improves.
Be set with pin bearing on described crank pin, described connecting rod is sleeved on described pin bearing, connects connecting rod by pin bearing thus, has reduced the surface friction drag of linkage mechanism, and the connecting rod wearing and tearing reduce, and have improved working efficiency.
The beneficial effects of the utility model are: the utility model is simple in structure, and is easy to make, adds lubricant oil convenient, can be comprehensively lubricated for connecting rod, and connecting rod wearing and tearing simultaneously reduce, and the life-span increases, and mechanical efficiency improves.
