Description
Technical field
The utility model is related to a kind of connecting rod for being used to transmit motion and power, more particularly to a kind of small end and big end fully profit
Sliding connecting rod.
Background technology
The two ends of connecting rod are hinged to transmit the rod member of motion and power respectively with driving member and driven member.For example, past
Bring back to life in plug dynamic power machine and compressor, connect piston and crank with connecting rod, active force suffered by piston is transmitted to bent axle, will
The reciprocating motion of piston is changed into the rotary motion of bent axle.
Connecting rod is made up of three parts, i.e. small end, big end and shaft, and small end is also referred to as microcephaly, and big end is also referred to as major part, small end
By small end connecting hole and piston pin connection, big end is connected by end connecting hole greatly with bent axle, and shaft is connected to small end and big end
Between.The small end of connecting rod is generally thin-wall circular loop configuration, for the abrasion between reduction and piston pin, is typically entered in small head bore internal pressure
Thin-walled bronze bushing, drilling or groove milling on small end and bushing, so that the oily foam splashed enters matching somebody with somebody for lubricating bushings and piston pin
Close surface.In order to express easily, general that bushing is directly merged into referred to as small end with small end, small end is provided with radial direction oil hole, application
When lubricating oil matching surface with piston pin in small end is entered by radial direction oil hole, reach lubrication purpose.
Existing connecting rod, it is general only to enter oil hole provided with the radial direction entered for lubricating oil in small end connecting hole in small end,
Do not enter oil hole similarly radially then at big end, the gap that a small amount of lubricating oil can be connected by holding greatly with driven member enters
Lubrication is played in big end connecting hole.This traditional structure connecting rod load it is very big in the case of be to have no problem,
But in the case of extreme load, the lubrication shortage of oil into big end connecting hole comparatively fast may even be damaged because of its big end abrasion,
So as to reduce connecting rod service life.In addition, existing connecting rod sets fluted in order to which lubricating oil circulates on shaft surface, one
Determine to reduce connecting rod strength in degree, make its application by a definite limitation, and reduce its aesthetics.
Utility model content
The purpose of this utility model, which is that, provides a kind of small end and big end sufficient lubrication in order to solve the above problems
Connecting rod.
The utility model is achieved through the following technical solutions above-mentioned purpose：
A kind of small end and the connecting rod of big end sufficient lubrication, including shaft and the small end, big for being respectively arranged on the shaft two ends
End, the small end is provided with small end connecting hole, and the big end is provided with axial central through hole provided with big hold in connecting hole, the shaft,
The two ends of the axial central through hole are communicated with the small end connecting hole and the big end connecting hole respectively.Axial central through hole rises
To the effect of grease channel can be formed between the small end connecting hole of small end and the big end connecting hole held greatly, so as to be big end
Sufficient lubrication and lubricating oil enter small end connecting hole and the approach of big end connecting hole plays important place mat effect.
The big end surfaces, which are provided with, to be used to allow lubricating oil to enter the big end connecting hole outside the big end connecting hole
The position intersected on interior breach, the hole wall of the big end connecting hole with the axial central through hole is provided with deep gouge, the deep gouge
Width or diameter be more than the axial central through hole diameter.
According to applying needs, a diameter of 1-5mm of the axial central through hole.
In order to reduce shaft material and proof strength, if the axial direction of the shaft be above-below direction, the shaft it is front and rear
Both side surface and left and right sides surface are equipped with one or more evagination arcwall faces.This structure has proof strength and loss of weight concurrently
Dual-use function, could be realized on the basis of above-mentioned setting axial central through hole, because if without axial central through hole, then
In shaft groove can be set to be circulated in order to lubricating oil.
In order to ensure bonding strength, the junction of the small end and the shaft is provided with small end concave curved surface；It is described big
End and the junction of the shaft are provided with big end concave curved surface.
The beneficial effects of the utility model are：
The utility model in shaft by setting connection small end connecting hole and the greatly axial central through hole of end connecting hole, really
Humectation lubricating oil can enter in small end connecting hole and big end connecting hole, small end and big end is realized good lubricant effect,
And lubricating oil can be entered by any one end in small end and big end, be easy to product design and processing, be particularly suitable for use in heavy burden
Application scenario is carried, harsh lubricating requirement is disclosure satisfy that；The shaft of this connecting rod no longer sets groove, but directly sets a Hu many
Individual evagination arcwall face, makes the intensity of connecting rod higher, and more attractive in appearance.
