Abstract
The utility model provides a structure of a small end of a connecting rod, which comprises an oil inlet of a small end of a connecting rod and a connecting rod bushing oil sink, the oil inlet the a small end of the connecting rod is arranged on the lateral face of the small end of a connecting rod, the connecting rod bushing oil sink utilizes an X-shaped structure, and the oil inlet of the small end of the connecting rod is communicated with the connecting rod bushing oil sink. The structure of the small end of the connecting rod has the advantages of improving top intensity of the small end of the connecting rod, and sufficiently lubricating the connecting rod bushing to be adapted to the requirement of high power and high explosive pressure of heavy duty diesel engines.
Description
Technical field
The utility model relates to a kind of connecting rod small end structure, especially relates to the connecting rod small end structure that connecting rod small end filler opening and connecting rob bushing tank structure are optimized.
Background technique
At present, existing connecting rod small end filler opening is opened at the connecting rod small end top, and connecting rob bushing adopts ring or man type oil groove.High-power, the large diesel engine detonation pressure requires to adopt the stepped shaft connecting rod small end up to more than the 180bar, and the connecting rod small end filler opening is held at the connecting rod small end top can weaken connecting rod small end top intensity, therefore needs the novel connecting rod small end structure of design.
Summary of the invention
At the deficiencies in the prior art, the utility model provides a kind of connecting rod small end structure that improves connecting rod small end top intensity.
The utility model connecting rod small end structure comprises connecting rod small end filler opening and connecting rob bushing oil groove, and the connecting rod small end filler opening is arranged on the side of connecting rod small end, and the connecting rob bushing oil groove adopts x shape structure, and the connecting rod small end filler opening communicates with the connecting rob bushing oil groove.
In the utility model connecting rod small end structure, two sides of connecting rod small end all are provided with the connecting rod small end filler opening, and two filler openings are best for being symmetrical arranged, and communicate with connecting rob bushing x shape oil groove respectively.
The advantage of the little header structure of the utility model is that filler opening is opened in the connecting rod small end side, has guaranteed connecting rod small end intensity, and the connecting rob bushing oil groove adopts x shape, match with the side filler opening, guaranteed the lubricated of connecting rob bushing, high-power to adapt to, the high pressure of explosion of large diesel engine needs.
Description of drawings
Fig. 1 is the plan view of the utility model connecting rod small end;
Fig. 2 is the left view of the utility model connecting rod small end;
Among Fig. 1～Fig. 2,1-connecting rod small end top, 2-connecting rod small end side, 3-filler opening, 4-connecting rob bushing oil groove, 5-connecting rob bushing.
Embodiment
A kind of most preferred embodiment below in conjunction with accompanying drawing further specifies the utility model connecting rod small end 26S Proteasome Structure and Function.
The most preferred embodiment that the utility model is implemented such as Fig. 1～shown in Figure 2, drive hydraulic fluid port 3 in connecting rod small end side 2, connecting rob bushing oil groove 4 on the connecting rob bushing 5 is an x shape, and filler opening 3 is symmetrical arranged in two sides of connecting rod small end, and two filler openings communicate with connecting rob bushing x shape oil groove respectively.During work, the lubricant oil that enters connecting rob bushing 5 from the filler opening 3 of connecting rod small end side 2 flows in x shape oil groove 4, and connecting rob bushing is lubricated, and satisfies the connecting rob bushing lubricating requirement, does not have filler opening on the connecting rod small end top 1, and intensity is guaranteed.
It should be noted that at last: above embodiment only in order to the explanation the utility model and and the described technological scheme of unrestricted the utility model; Therefore, although this specification has been described in detail the utility model with reference to each above-mentioned embodiment,, those of ordinary skill in the art should be appreciated that still and can make amendment or be equal to replacement the utility model; And all do not break away from the technological scheme and the improvement thereof of spirit and scope of the present utility model, and it all should be encompassed in the claim scope of the present utility model.
