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 one kind is easy to small end sufficient lubrication
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
With piston pin connection, big end is connected with bent axle, and shaft is connected between small end and big end.The small end of connecting rod is generally thin-wall circular annular
Structure, for the abrasion between reduction and piston pin, typically enters thin-walled bronze bushing in small head bore internal pressure, is bored on small end and bushing
Hole or groove milling, so that the oily foam splashed enters the matching surface of lubricating bushings and piston pin.In order to express easily, it is general directly
Bushing merge with small end referred to as small end, small end be provided with radial direction oil hole, using when lubricating oil by radial direction oil hole enter small end in
With the matching surface of piston pin, lubrication purpose is reached.
Existing connecting rod, the periphery of its small end is smooth arc surface, and its radial direction oil hole is arranged on small end close to shaft
Position, using the less feature of width at this realize lubricating oil enter small end endoporus purpose.But, due to the periphery of small end
For smooth arc surface, so lubricating oil can only enter radial direction oil hole by the position of close shaft, narrower width, transmitted in power
When larger, the speed and oil mass that lubricating oil enters are all not enough, influence lubricant effect, and its lubricating oil entrance of this traditional structure
The speed and oil mass of radial direction oil hole can also be influenceed by connecting rod direction to a certain extent, also be unfavorable for the lubrication effect realized
Really.
Utility model content
The purpose of this utility model be that provide a kind of lubricating oil to solve the above problems can not be by connecting rod side
To influence and it can rapidly enter the connecting rod for being easy to small end sufficient lubrication of small end radial direction oil hole.
The utility model is achieved through the following technical solutions above-mentioned purpose：
A kind of connecting rod for being easy to small end sufficient lubrication, including shaft and the small end at the shaft two ends, big end are respectively arranged on,
The small end, which is provided with, is used for the radial direction through hole that lubricating oil circulates, and ring-type of the outer surface provided with non-close of the small end is recessed
Groove, the annular recess is communicated with the outer end of the radial direction through hole.The annular recess of non-close, its central angle also at least above
180 °, so the scope that lubricating oil is circulated by annular recess is larger, lubricating oil in conventional linkage is solved well and enters footpath
It is smaller and the problem of by connecting rod aspect effect to the region of through hole.
Preferably, the width of the annular recess is more than the diameter of the radial direction through hole, and the radial direction through hole is located at described
Between the both sides of annular recess.So it is more conducive to lubricating oil and smoothly enters radial direction through hole.
For the ease of processing and attractive in appearance, the radial section of the annular recess is circular arc.
For the energy loss when mitigating weight on the premise of not influenceing connecting rod strength to reduce link motion, if described
The axial direction of shaft is above-below direction, and the left and right sides surface of the shaft is respectively equipped with main deep gouge, the front and rear sides of the shaft
Surface is respectively equipped with auxiliary deep gouge.
Further, the surface at the big end is provided with multiple equally distributed loss of weight deep gouges.
The beneficial effects of the utility model are：
The utility model by wrist-pin end of connecting rod outer surface set annular recess, make lubricating oil not only can by by
Nearly shaft, the position of narrower width enter radial direction oil hole, and can flow to small end by any position of annular recess
Lubrication is played in radial direction through hole, and then in entrance small end, the speed and oil mass that lubricating oil enters are all more sufficient, improve
Lubricant effect, and lubricating oil enter radial direction oil hole speed and oil mass will not be influenceed substantially by connecting rod direction, it is especially suitable
Transmit and applied in larger occasion in power in connecting rod.
Brief description of the drawings
Fig. 1 is the shaft in the main structure diagram of the connecting rod described in the utility model for being easy to small end sufficient lubrication, figure
It is half-sectional structural representation with small end；
Fig. 2 is the left view structural representation of the connecting rod described in the utility model for being easy to small end sufficient lubrication.
Embodiment
The utility model is described in further detail below in conjunction with the accompanying drawings：
As depicted in figs. 1 and 2, the connecting rod described in the utility model for being easy to small end sufficient lubrication includes shaft 3 and set respectively
Small end 1 in the two ends of shaft 3,5 are held greatly, small end 1, which is provided with, is used for the radial direction through hole 7 that lubricating oil circulates, the outer surface of small end 1
Annular recess 6 provided with non-close, annular recess 6 is communicated with the outer end of radial direction through hole 7, and the radial section of annular recess 6 is circle
Arc and its width are more than the diameter of radial direction through hole 7, and radial direction through hole 7 is located between the both sides of annular recess 6, the surface at big end 5
Provided with multiple equally distributed loss of weight deep gouges 10；If the axial direction of shaft 3 is above-below direction, the left and right sides surface of shaft 3 is distinguished
