This engine supercharger returns oil pipe gasket has set up the sign terminal surface that prevents the loading error for avoid the protruding assembly direction mistake of annular of sealed effect, improved the convenience of assembly, eliminated the oil leak risk.
Description
Technical field
The utility model relates to Sealing technical field, particularly relates to a kind of engine supercharger gasket of oil return pipe.
Background technique
Lubricant oil in engine supercharger flows back to engine sump tank via oil return pipe of supercharger, is Flange joint between pressurized machine and oil return pipe of supercharger, for preventing lubricant oil from spilling, needs to use gasket seal between two flanges.In order to improve the sealing of gasket seal, generally pressure ripple is set on gasket seal, to increase the elastic strain of pad.Pressure ripple direction should to be screwed into direction identical with bolt, and when bolt tightening, the distortion that pad produces forms one and encloses sealing strip between two flanged surfaces, prevents leakage of oil.
But gasket of oil return pipe of supercharger pressure ripple is not clearly, is easy to misloading, ripple will be pressed towards anti-loaded during assembling, like this in bolt tightening process, be difficult to the uniformity ensureing that pressure ripple extends, reduce sealing, there is the risk of leakage of oil.
Therefore, those skilled in the art need the structure improving engine supercharger gasket of oil return pipe, to solve the above-mentioned problems in the prior art.
Model utility content
The purpose of this utility model is to provide a kind of engine supercharger gasket of oil return pipe, and it has good sealability and mistake proofing assembling structure, improves the convenience of assembling, can avoid the risk of leakage of oil.
To achieve these goals, the utility model provides following technological scheme:
A kind of engine supercharger gasket of oil return pipe, comprise shim body, described shim body is provided with the pilot hole coordinated with oil return pipe of supercharger, the outer of described pilot hole is arranged with the annular protrusion concentric with described pilot hole, the two edges that described shim body is adjacent are respectively equipped with straight mark section, the section corresponding matching on described mark section and pressurizer oil pipe flange.
Preferably, the circumferential edge of described shim body is provided with many groups and turns over pawl, described in turn over pawl inner side surface fit with described pressurizer oil pipe flange and abut.
Preferably, described in turn over pawl be elastic piece structure, and its bottom is provided with the flange away from described pressurizer oil pipe flange turnover.
Preferably, described shim body is oval, turns over pawl and splits on the edge of longer a pair of described shim body, and be arranged symmetrically with described in many groups.
Preferably, turn over pawl and described shim body described in be formed in one structure.
Preferably, the height of described annular protrusion is 0.25mm ~ 0.5mm.
The engine supercharger gasket of oil return pipe that the utility model provides, shim body is provided with annular protrusion, in order to increase the elastic strain of pad, strengthen sealing, and be provided with straight mark section respectively on two edges that shim body is adjacent, section corresponding matching on this mark section and pressurizer oil pipe flange, when assembling, can ensure that described annular protrusion is placed towards correct direction, avoiding loading error, improve the convenience of assembling, avoid the problem of leakage of oil.
Accompanying drawing explanation
In order to be illustrated more clearly in the embodiment of the present application or technological scheme of the prior art, being briefly described to the accompanying drawing used required in embodiment below, and will being described in further detail specific embodiments of the invention by reference to the accompanying drawings, wherein
The structural representation of the engine supercharger gasket of oil return pipe that Fig. 1 provides for the utility model embodiment;
Fig. 2 is the plan view of engine supercharger gasket of oil return pipe in Fig. 1.
Label declaration wherein in above-mentioned accompanying drawing is as follows:
1-shim body;
11-pilot hole, 12-annular protrusion, 13-identifies section, and 14-turns over pawl.
Embodiment
In order to make those skilled in the art understand the technical solution of the utility model better, do to introduce in detail further to this programme below in conjunction with specific embodiment.
With reference to figure 1 and Fig. 2, the utility model provides a kind of engine supercharger gasket of oil return pipe, comprise shim body 1, described shim body 1 is provided with the pilot hole 11 coordinated with oil return pipe of supercharger, the outer of described pilot hole 11 is arranged with the annular protrusion 12 concentric with described pilot hole 11, and the height of described annular protrusion 12 is 0.25mm ~ 0.5mm.The two edges that described shim body 1 is adjacent are respectively equipped with straight mark section 13, described mark section 13 and the section corresponding matching on pressurizer oil pipe flange.During assembling, after described mark section 13 is alignd with the corresponding section on described pressurizer oil pipe flange, can ensure that the assembly direction of described annular protrusion 12 is correct, when using bolt urgent, described annular protrusion 12 effectively can be compressed distortion, thus play good seal action, prevent leakage of oil.
Further, the circumferential edge of described shim body 1 is also provided with many groups and turns over pawl 14, the described inner side surface turning over pawl 14 is fitted with described pressurizer oil pipe flange and is abutted, described installation of turning over pawl 14 pairs of pads serves further mark action, described mark section 13 is coordinated to use, avoid because gasket construction is less, operator ignore the loading error that described mark section 13 causes.In addition, described in turn over pawl 14 and also fastening effect played to the installation of described shim body 1 on described pressurizer oil pipe flange, turn over pawl 14 described in many groups and be clamped on described pressurizer oil pipe flange, prevent pad play or loosen.
Preferably, described in turn over pawl 14 for elastic piece structure, strengthen clamping force, and the bottom of described elastic piece structure is provided with the flange away from described pressurizer oil pipe flange turnover, is convenient to the operation during dismounting of described engine supercharger gasket of oil return pipe.
In the present embodiment, described shim body 1 is oval, turns over pawl 14 and splits on described shim body 1 edge of longer a pair, and be arranged symmetrically with described in many groups.Alternatively, each described edge is all arranged described in two groups turn over pawl 14.
