Abstract
The utility model discloses a kind of new structure bearing shell, the outer surface of bearing shell body one end is provided with groove, groove does not destroy the inner surface of bearing shell body, retention Hp it is provided with in groove, therefore retention Hp does not the most destroy the inner surface of bearing shell body, bearing shell body internal surface does not has groove and smooth and continuous, so may be reduced by lubricating oil leakage, reduce oil pump capacity, thus reduce the power driving lubricating oil pump, and then reduce the purpose of fuel oil consumption, additionally, the retention Hp of this structure will not form interference to oil film, the lubricating status of bearing can be improved, and the service life of bearing shell can be extended.
Description
Technical field
This utility model relates to a kind of new structure bearing shell.
Background technology
Bearing shell is the part of sliding bearing and journal contact, is shaped as the semicolumn of tiles, unusual light, bearing shell is provided with retention Hp, retention Hp is the bulge-structure of bearing shell adapter section, and retention Hp is mated with the locating slot in dead eye, so that bearing shell can be properly positioned during assembling.In prior art, retention Hp is directly gone out from inner surface of bearing bush, the most existing retention Hp typically uses and runs through type, the fluted existence of inner surface of bearing bush of this structure, this groove is a passage of lubricating oil leakage, add engine oil leakage quantity, when machine oil flows through retention Hp inner surface, sudden change due to cross section of fluid channel, easily because of moment depression formation bubble, in the violent explosion of instantaneous bubble that high pressure recovers, bubble release blasting energy, form high frequency micro-injection shock wave, strong erosion working surface, thus cause the deformation of bearing shell surfacing, tired, final material peels off from surface, form cavitation erosion pit or pit.
Utility model content
The technical problems to be solved in the utility model is for drawbacks described above, it is provided that a kind of new structure bearing shell, and the retention Hp of this new structure bearing shell does not destroy inner surface of bearing bush, can reduce lubricating oil leakage, thus reduce the power driving lubricating oil pump.
In order to solve above-mentioned technical problem, this utility model includes bearing shell body, and it is structurally characterized in that: the outer surface of described bearing shell body one end is provided with retention Hp.
The outer surface of described bearing shell body one end is provided with groove, is provided with retention Hp in described groove, and described groove extends towards its inside from the upper surface of bearing shell body and appearance thereof.
Described retention Hp is arranged to the bottom angled of bearing shell body from the top of bearing shell body.
The width of described retention Hp cross section tapers into the bottom of bearing shell body from the top of bearing shell body.
The medial part of described retention Hp is affixed with the radial outer wall of groove, and the lateral part of retention Hp stretches out groove.
Angle between lateral surface and the plane at groove radial outer wall place of described retention Hp is acute angle.
The degree of depth of described groove is 1st/2nd to three/3rds of bearing shell body thickness.
The upper surface of described retention Hp is less than the upper surface of bearing shell body.
The upper surface of described retention Hp is concordant with the upper surface of bearing shell body.
Advantageous effect after employing such scheme is: the outer surface of bearing shell body one end is provided with groove, groove does not destroy the inner surface of bearing shell body, retention Hp it is provided with in groove, retention Hp can also be set directly at the outer surface of bearing shell body, in both structures, retention Hp is all without the inner surface destroying bearing shell body, bearing shell body internal surface does not has groove and smooth and continuous, so may be reduced by lubricating oil leakage, reduce oil pump capacity, thus reduce the power driving lubricating oil pump, and then reduce the purpose of fuel oil consumption.It addition, the retention Hp of both the above structure will not form interference to oil film, the lubricating status of bearing can be improved, and the service life of bearing shell can be extended.
Accompanying drawing explanation
Below in conjunction with the accompanying drawings detailed description of the invention of the present utility model is described in further detail:
Fig. 1 is the structural representation of a kind of embodiment of this utility model；
Fig. 2 is the structural representation of this utility model another embodiment.
Detailed description of the invention
As depicted in figs. 1 and 2, this new structure bearing shell includes the bearing shell body 1 being arranged at sliding bearing and journal contact, and bearing shell body 1 is the semi-cylindrical of tiles.The first embodiment: the outer surface of bearing shell body 1 one end is provided with groove 11, groove 11 extends towards its inside from the upper surface of bearing shell body 1 and appearance thereof, the degree of depth of groove 11 is that 1st/2nd to three/3rds of bearing shell body 1 thickness, i.e. groove 11 do not destroy the inner surface of bearing shell body 1.Retention Hp 12 it is provided with in groove 11, in the present embodiment, the medial part of retention Hp 12 is affixed with the radial outer wall of groove 11, the bottom of retention Hp 12 is affixed with the radial direction diapire of groove 11, can also be one-body molded between retention Hp 12 and groove 11, the lateral part of retention Hp 12 stretches out groove 11, retention Hp 12 is arranged to the bottom angled of bearing shell body 1 from the top of bearing shell body 1, in the present embodiment, the width of retention Hp 12 cross section tapers into the bottom of bearing shell body 1 from the top of bearing shell body 1, i.e. between the plane at the radial outer wall place of the lateral surface of retention Hp 12 and groove 11, shape is in an angle, this angle is acute angle.Retention Hp 12 can coordinate with the locating slot in dead eye, and this fit system is prior art, does not repeats them here.The upper surface of retention Hp 12 is less than the upper surface of bearing shell body 1, and this structure is easy to retention Hp 12 and the coordinating of locating slot in dead eye.
As shown in Figure 2, the second embodiment: the outer surface of bearing shell body 1 one end is provided with retention Hp 12, retention Hp 12 is arranged to the bottom angled of bearing shell body 1 from the top of bearing shell body 1, in the present embodiment, the width of retention Hp 12 cross section tapers into the bottom of bearing shell body 1 from the top of bearing shell body 1, i.e. between lateral surface and the outer surface of bearing shell body 1 of retention Hp 12 tangent shape in an angle, this angle is acute angle.The upper surface of retention Hp 12 is concordant with the upper surface of bearing shell body 1.Retention Hp 12 can coordinate with the locating slot in dead eye, and this fit system is prior art, does not repeats them here.
As depicted in figs. 1 and 2, in the first embodiment of this utility model, retention Hp 12 is arranged in groove 11, groove 11 does not destroy the inner surface of bearing shell body 1, in the second embodiment, retention Hp 12 is set directly at the outer surface of bearing shell body 1, therefore in two kinds of embodiments, retention Hp 12 does not the most destroy the inner surface of bearing shell body 1, owing to bearing shell body 1 inner surface does not has groove, and bearing shell body 1 inner surface is smooth, continuous, so may be reduced by lubricating oil leakage, reduce oil pump capacity, thus reduce the power driving lubricating oil pump, and then reduce the purpose of fuel oil consumption.It addition, the retention Hp 12 of this structure will not form interference to oil film, the lubricating status of bearing can be improved, and the service life of bearing shell can be extended.
This utility model is not limited to above-mentioned detailed description of the invention, those skilled in the art, on the premise of without departing from spirit and scope of the present utility model, can do some changes and modification.Protection domain of the present utility model should be as the criterion with claim of the present utility model.
