Abstract
The utility model discloses a sealing rubber strip, which has a trapezoidal cross section. Two parallel frameworks made from a carbon fiber composite material are arranged in the trapezoidal cross section. The problem of difficulty in the fixation of the sealing rubber strip on a crankshaft box is improved, the phenomena of sealing rubber strip deviation, expansion deformation, breakage and the like caused by non-uniform stress and vibration are avoided, the problem of leakage between the crankshaft box and an engine body assembly in a diesel engine is effectively solved, the service life of the sealing rubber strip is prolonged, and the stability and the reliability of normal running of the diesel engine are ensured.
Description
Technical field
The utility model belongs to machinery manufacturing technology field, relates in particular to a kind of sealing joint strip.
Background technique
Sealing to diesel engine cam axle box bottom surface, generally that sealing joint strip with elliptic cross-section is fixed in the groove of camshaft case bottom surface with sealer, after glue to be sealed is cooling, to be fitted in the camshaft case of sealing joint strip on body again, then other system unit of mounting diesel engine, defeat tight camshaft case by other system unit comprehensive function, complete the sealing between the assembling of camshaft case and body.Because camshaft case is long, and the unstability of the sealing joint strip form structure of elliptic cross-section, the difficult that is fixed up is easy to occur skew.In addition, in press-fiting process, also require other system unit evenly necessary to the active force of camshaft case, otherwise sealing joint strip will produce because of unbalance stress the inclined to one side phenomenon of pressure, affects sealing effect.Moreover diesel engine is in the process of running up, and oscillation phenomenon can appear in each system unit, also can cause the phenomenon such as fixed position skew, dilatancy, fracture of sealing joint strip.
The model utility content
The purpose of this utility model overcomes the deficiency of above-mentioned prior art exactly, and a kind of sealing joint strip is provided, and the stationary positioned during ease of assembly improves its sealing effect and working life.
The purpose of this utility model is achieved in that a kind of sealing joint strip, it is characterized in that its cross section is trapezoidal.
In order to realize better the purpose of this utility model, contain the skeleton of two parallel carbon fibre composite materials in above-mentioned trapezoidal cross-section.
Adopt scheme of the present utility model, improved sealing joint strip fixing hard problem on camshaft case, and avoided because of unbalance stress and vibrated the phenomenons such as the sealing joint strip that causes is pressed partially, dilatancy, fracture, effectively solved this position leakage problem of diesel engine, improve the working life of sealing joint strip, guaranteed the Stability and dependability of the normal operation of diesel engine.
Description of drawings
Fig. 1 is the cross section principle schematic of the utility model embodiment's sealing joint strip.
Fig. 2 is the utility model embodiment's sealing joint strip application principle schematic diagram.
Number in the figure: 1-skeleton, 2-fluosilicic rubber, 3-camshaft case, 4-sealing joint strip, the assembling of 5-body.
Embodiment
For the purpose, technological scheme and the advantage that make the utility model embodiment clearer, below in conjunction with the accompanying drawing in the utility model embodiment, technological scheme in the utility model embodiment is clearly and completely described, obviously, described embodiment is the utility model part embodiment, rather than whole embodiments.Based on the embodiment in the utility model, those of ordinary skills are not making the every other embodiment who obtains under the creative work prerequisite, all belong to the scope of the utility model protection.
Referring to Fig. 1 and Fig. 2, the sealing joint strip of the present embodiment, its cross section are trapezoidal fluosilicic rubber 2, include the skeleton 1 of two parallel carbon fibre composite materials.Use this kind sealing joint strip on diesel engine, at first sealing joint strip 4 use sealers are fixed in the groove of camshaft case 3 bottom surfaces, after glue to be sealed is cooling, to be fitted in the camshaft case 3 of sealing joint strip 4 again in body assembling 5, then other system unit of mounting diesel engine, defeat tight camshaft case by other system unit comprehensive function, complete the sealing between the assembling of camshaft case and body.
It should be noted that at last: above embodiment only in order to the technical solution of the utility model to be described, is not intended to limit; Although with reference to previous embodiment, the utility model is had been described in detail, those of ordinary skill in the art is to be understood that: it still can be modified to the technological scheme that aforementioned each embodiment puts down in writing, and perhaps part technical characteristics wherein is equal to replacement; And these modifications or replacement do not make the essence of appropriate technical solution break away from the spirit and scope of each embodiment's technological scheme of the utility model.
Claims (2)
1. a sealing joint strip, is characterized in that its cross section is trapezoidal.
2. root a tree name sealing joint strip claimed in claim 1 is characterized in that containing in above-mentioned trapezoidal cross-section the skeleton of two parallel carbon fibre composite materials.
