Abstract
The utility model provides a locomotive diesel engine is with flexible tappet cover, relates to diesel engine tappet cover technical field, including body, setting at the joint at body both ends, the body includes first body, second body and is used for connecting the rubber body of first body and first body, and the one end that first body and first body are relative is connected with the help of the rubber body, and the outside of first body and first body all is connected with the joint. The inner wall of the rubber pipe body is respectively bonded with the outer walls of the first pipe body and the second pipe body, and the middle part of the inner wall of the rubber pipe body is provided with an annular bulge and is arranged between the first pipe body and the second pipe body. This structure when installation according to actual conditions, the adaptive bending deformation that carries on avoids producing stress, makes the joint of tappet cover closely cooperate completely with the interface of diesel engine cylinder, and this structure can play the cushioning effect moreover, improves life.
Description
Technical Field
The utility model relates to a diesel engine tappet cover technical field specifically is a but has related to a locomotive is flexible tappet cover for diesel engine.
Background
The diesel engine for diesel locomotive all is equipped with sealed tappet cover in the cylinder tappet outside, the tappet cover is for being cylindric tubular metal pipe component, aim at protects the tappet and the sealed of lubricating oil, but leakage problem often takes place when practical application, the reason does not possess the condition of absorption or compensation at the tappet cover of tubular metal structure, when installing the tappet cover, because expend with heat and contract with cold or proofreading error, two relative interfaces on the diesel engine can not guarantee to be complete axial relative, receive the axial stress influence, there is the unable complete coincidence of deviation in the joint gap angle of joint and diesel engine cylinder at tappet cover both ends, thereby make the gasket atress of the connecting portion of tappet cover and diesel engine cylinder uneven, the oil leak phenomenon appears in the easy damage of gasket during vibrations.
SUMMERY OF THE UTILITY MODEL
The utility model discloses a solve above-mentioned problem, provide a locomotive is flexible tappet cover for diesel engine, the rubber body part of tappet cover when the installation, according to actual conditions, the adaptable bending deformation that carries on avoids the body to produce resistance, makes the joint of tappet cover can closely cooperate completely with the interface of diesel engine cylinder, and this structure can play the cushioning effect moreover, improves life.
The utility model provides a technical scheme be, provide a locomotive is flexible tappet cover for diesel engine, including body, setting at the joint at body both ends, the body includes first body, second body and is used for connecting the rubber body of first body and first body, and the one end that first body and second body are relative vulcanizes the bonding with the help of the rubber body and connects, and the outside of first body and first body all is connected with the joint.
The inner wall of the rubber pipe body is respectively connected with the outer walls of the first pipe body and the second pipe body in a vulcanization bonding mode, and the middle of the inner wall of the rubber pipe body is provided with an annular bulge and is arranged between the first pipe body and the second pipe body.
The utility model has the advantages that:
1. when the tappet sleeve is installed, the rubber pipe body of the tappet sleeve can be bent and deformed adaptively according to actual conditions, so that resistance is avoided, and a joint of the tappet sleeve can be completely and closely matched with an interface of a diesel engine cylinder;
2. the body structure of syllogic can play the cushioning effect, reduces the vibrations transmission of diesel engine, improves the life of diesel engine and tappet cover.
Drawings
Fig. 1 is a schematic structural diagram of the present invention;
fig. 2 is a schematic sectional structure of the present invention;
FIG. 3 is a schematic cross-sectional view of a rubber tube;
fig. 4 is a schematic structural diagram of another embodiment of the present invention.
In the attached drawings, the pipe comprises a first pipe body 1, a second pipe body 2, a rubber pipe body 3, an annular bulge 4, an annular bulge 5 and a joint.
Detailed Description
As shown in fig. 1-4, the utility model provides a locomotive diesel engine is with flexible tappet cover, including the body, set up the joint 5 at the body both ends, the body includes first body 1, second body 2 and is used for connecting the rubber body 3 of first body 1 and first body 1, and the one end that first body 1 and second body 2 are relative is vulcanized the bonding with the help of rubber body 3 and is connected, and the outside of first body 1 and first body 1 all is connected with the joint.
The pipe body comprises first body 1, rubber body 3 and second body 2 that connect gradually, wherein rubber body 3 is soft body, form by the vulcanization adhesion die pressing technology of rubber materials and first body 1, the pouring of second body 2, when the installation, the rubber body 3 of tappet cover is according to actual conditions, the bending deformation that can adapt to carries out, avoid producing stress, make the joint of tappet cover can closely cooperate completely with the interface of diesel engine cylinder, improve the leakproofness of connecting, the condition of avoiding the machine oil seepage takes place.
The structure adopts a direct adhesion method, a tackifier is uniformly mixed into a rubber material, the rubber material is vulcanized in a mould, and when the rubber is heated and vulcanized to be molded, the rubber material is firmly adhered with the metal.
As shown in fig. 1-4, the inner wall of the rubber tube 3 is vulcanized and bonded with the outer walls of the first tube 1 and the second tube 2, and an annular protrusion 4 is disposed in the middle of the inner wall of the rubber tube 3 and disposed between the first tube 1 and the second tube 2.
The contact area of the rubber tube body 3 with the first tube body 1 and the second tube body 2 is increased, and a gap or a recess between the first tube body 1 and the second tube body 2 is filled, so that the inner wall of the tappet sleeve is smooth, namely, the inner walls of the first tube body 1, the second tube body 2 and the rubber tube body 3 are the same peripheral surface, meanwhile, the wall thickness of the rubber tube body 3 between the first tube body 1 and the second tube body 2 is increased, and the strength is increased.
This structure can be according to the demand, increases in the rubber layer of rubber tube body 3 and weaves cloth and/or the further increase strength of wire net, presss from both sides the cloth rubber tube promptly, and the joint at body both ends can adopt different joints 5 according to the demand, has listed the tappet cover that two kinds of differences connect in the drawing to this better effect to this structure explains.
