Abstract
The utility model discloses a camshaft bearing lid, including the bearing cap body, the one side that is used for on the bearing cap body being connected with the cylinder head cooperation is equipped with the dead eye, the subsurface spill of dead eye becomes to be used for storing the oil storage tank of lubricating oil, the utility model discloses a camshaft bearing lid adds the oil storage tank through the surface at the dead eye, and the oil storage tank has increased the storage capacity of lubricating oil between during operation dead eye and the bearing, can strengthen the lubrication action at bearing cap and cam shaft connection position, prevents the lubricated not enough condition, reduces wearing and tearing, and increase of service life satisfies engine requirement in the aspect of lubricated under abominable operating mode.
Description
Technical field
The utility model relates to a kind of engine components, particularly a kind of camshaft-bearing cap.
Background technique
The effect of engine camshaft bearing cap is stationary cam axle together with cylinder head, makes camshaft energy axially locating.Existing camshaft-bearing cap only possesses simply for the function of stationary cam axle substantially, the requirement of motor under bad working environments in lubrication can not be met, particularly when camshaft high speed rotating, often there is the situation of lack of lubrication in the connection part (i.e. axle journal) of camshaft and camshaft-bearing cap, cause this position serious wear, reduce its working life.
Therefore, for solving the problems of the technologies described above, just need a kind of camshaft-bearing cap, the lubrication of itself and camshaft connection part can be strengthened, prevent the situation of lack of lubrication, reduce wearing and tearing, increase the service life, meet the requirement of motor under bad working environments in lubrication.
Model utility content
In view of this, the purpose of this utility model is to provide a kind of camshaft-bearing cap, can strengthen the lubrication of itself and camshaft connection part, prevent the situation of lack of lubrication, reduce wearing and tearing, increase the service life, meet the requirement of motor under bad working environments in lubrication.
Camshaft-bearing cap of the present utility model, comprises bearing cap body, and the side for being connected with cylinder head on described bearing cap body is provided with bearing hole, and the recessed formation in surface of described bearing hole is for storing the oil storage tank of lubricant oil.
Further, the both sides of described bearing hole are provided with the buck plate for fitting with cylinder head, and described oil storage tank extends to the joint of bearing hole and corresponding buck plate to both sides.
Further, described oil storage tank is located in the middle part of bearing hole.
Further, the longitudinal section of described oil storage tank is semi-circular structure, and the radius of this semi-circular structure is 0.8mm-1.2mm.
Further, described buck plate is provided with for keeping itself and cylinder head to carry out the fastening structure of fitting.
Further, described fastening structure is the hole that buck plate is arranged, and the position in described hole is corresponding to the position of cylinder head upper bolt hole.
Further, the outer rim of described buck plate stretches out and is formed for the reinforcing part of reinforced assembly plate structure intensity.
Further, the cross section of described reinforcing part is trapezoidal.
The beneficial effects of the utility model: camshaft-bearing cap of the present utility model, oil storage tank is set up by the surface at bearing hole, the storage volume of lubricant oil between bearing hole and bearing when oil storage tank adds work, the lubrication of bearing cap and camshaft connection part can be strengthened, prevent the situation of lack of lubrication, reduce wearing and tearing, increase the service life, meet the requirement of motor under bad working environments in lubrication.
Accompanying drawing explanation
Below in conjunction with drawings and Examples, the utility model is further described:
Fig. 1 is structural representation of the present utility model;
Fig. 2 is A-A sectional view in Fig. 1.
Embodiment
Fig. 1 is structural representation of the present utility model, Fig. 2 is A-A sectional view in Fig. 1, as shown in the figure: the camshaft-bearing cap of the present embodiment, comprise bearing cap body 1, side for being connected with cylinder head on described bearing cap body 1 is provided with bearing hole 2, and the recessed formation in surface of described bearing hole 2 is for storing the oil storage tank 3 of lubricant oil; Bearing hole 2 semicircular in shape, the space formed for stationary cam axle of matching with another semicircular hole in cylinder head; By setting up oil storage tank 3 on the surface of bearing hole 2, the storage volume of lubricant oil between bearing hole 2 and bearing when oil storage tank 3 adds work, the lubrication of bearing cap and camshaft connection part can be strengthened, prevent the situation of lack of lubrication, reduce wearing and tearing, increase the service life, meet the requirement of motor under bad working environments in lubrication.
In the present embodiment, the both sides of described bearing hole 2 are provided with the buck plate 4 for fitting with cylinder head, and described oil storage tank 3 extends to the joint of bearing hole 2 and corresponding buck plate 4 to both sides; During use, buck plate 4 and cylinder head are fitted fixing, buck plate 4 is provided with for keeping itself and cylinder head to carry out the fastening structure of fitting, such as fastening structure can be the hole 4a that buck plate 4 is arranged, the position of described hole 4a is corresponding to the position of cylinder head upper bolt hole, by the connection of clamping bolt during use, can be fixed easily; In addition, the situation that during for preventing operation, camshaft-bearing cap is anti-loaded, on buck plate 4, holes 4a can be arranged by asymmetric position, and namely the center of holes 4a is not reciprocity to the length of bearing cap body 1 central position; Oil storage tank 3 extends to bearing hole 2 and the joint of corresponding buck plate 4 to both sides, effectively can improve the mobility of lubricant oil in oil storage tank 3, make lubrication more efficient.
In the present embodiment, described oil storage tank 3 is located in the middle part of bearing hole 2, makes lubricating uniform, improves the aesthetic of product simultaneously; In addition, the longitudinal section of described oil storage tank 3 is semi-circular structure, is convenient to processing, optimizes lubricating oil flow effect; The radius of this semi-circular structure is 0.8mm-1.2mm, is preferably 1.0mm.
In the present embodiment, the outer rim of described buck plate 4 stretches out the reinforcing part 4b formed for reinforced assembly plate 4 structural strength; The cross section of described reinforcing part 4b is trapezoidal.
What finally illustrate is, above embodiment is only in order to illustrate the technical solution of the utility model and unrestricted, although be described in detail the utility model with reference to preferred embodiment, those of ordinary skill in the art is to be understood that, can modify to the technical solution of the utility model or equivalent replacement, and not departing from aim and the scope of technical solutions of the utility model, it all should be encompassed in the middle of right of the present utility model.
