Abstract
The utility model discloses a kind of thrust bearing shell structure, including：Main bearing shell；And thrust plate, the thrust plate is diametrically hooked together with main bearing shell, and thrust plate is movable in the axial direction with main bearing shell, and when being not used, thrust plate is spot-welded together with main bearing shell, after assembling, the spot welding disengagement of thrust plate and main bearing shell.The thrust bearing shell structure effectively solves the problem of crankshaft thrust collar flatness is poor, so as to increase effective contact area of bent axle and thrust plate.
Description
Technical field
The utility model is related to field of internal combustion engine, more particularly to a kind of thrust bearing shell structure.
Background technology
To reduce location structure, increasing engine uses thrust bearing shell structure.Mainly there are two kinds of structures at present, i.e.,
Flanger bearing liner and fringing bearing shell.The cost of flanger bearing liner is low, but assembling uniformity is poor.The assembling uniformity of fringing bearing shell is good,
But process consistency is poor.When flanger bearing liner is assembled, under bolt of main bearing cap moment loading, thrust plate is easily deformed, assembling
The flatness of two thrust plates is poor up and down afterwards, thrust plate and bent axle localized contact, produces stress concentration, causes thrust plate alloy-layer
Peel off.The thrust plate of fringing bearing shell is riveted together with main bearing shell, and the structure requires higher to manufacturability, and thrust plate is easy to
Clamping stagnation, so as to influence the flatness of two thrust plates above and below after assembling.
The information for being disclosed in the background section is merely intended to increase the understanding to general background of the present utility model, and
It is not construed as recognizing or implies that the information structure has been existing well known to persons skilled in the art in any form
Technology.
Utility model content
The purpose of this utility model is to provide a kind of thrust bearing shell structure, effectively solves crankshaft thrust collar flatness
Poor the problem of, so as to increase effective contact area of bent axle and thrust plate.
To achieve the above object, the utility model provides a kind of thrust bearing shell structure, including：Main bearing shell；And thrust
Piece, the thrust plate is diametrically hooked together with main bearing shell, and thrust plate is movable in the axial direction with main bearing shell, when being not used, only
Push jack is spot-welded together with main bearing shell, after assembling, and the spot welding of thrust plate and main bearing shell is disengaged.
Preferably, the side of main bearing shell is provided with neck, and the side of neck is protruding with hangers, and the inside edge of thrust plate is provided with
The fixture block bent to the inside, fixture block is caught in after neck and is articulated on hangers.
Preferably, neck and fixture block are respectively three, and thrust plate is spot-welded together in centre position with main bearing shell.
Compared with prior art, the utility model has the advantages that：It is used as the thrust plate and main shaft of fabricated part
Watt, weld together and can not move freely in vanning, effectively thrust bearing shell can be prevented to be come off in circulation.Main shaft after assembling
Watt, and thrust plate disengages, thrust plate can axially move freely in bent axle, effectively solve asking for thrust bearing shell flatness difference
Topic, improves effective contact area of thrust plate and bent axle, reduces the abrasion of thrust plate, improves the reliability of engine.
Brief description of the drawings
Fig. 1 is the structural representation according to thrust bearing shell structure of the present utility model.
Embodiment
Below in conjunction with the accompanying drawings, embodiment of the present utility model is described in detail, it is to be understood that this practicality
New protection domain is not limited by embodiment.
Explicitly indicated that unless otherwise other, otherwise in entire disclosure and claims, term " comprising " or its change
Change such as "comprising" or " including " etc. and will be understood to comprise stated element or part, and do not exclude other members
Part or other parts.
As shown in figure 1, according to a kind of thrust bearing shell structure of the utility model embodiment, including：Main bearing shell 1 with
And thrust plate 2, the thrust plate 2 is diametrically hooked together with main bearing shell 1, and thrust plate 2 is movable in the axial direction with main bearing shell 1,
When being not used, thrust plate 2 and main bearing shell 1 are spot-welded together, after assembling, and the spot welding of thrust plate 2 and main bearing shell 1 is disengaged.
As a kind of preferred embodiment, the side of main bearing shell 1 is provided with neck, and the side of neck is protruding with hangers, thrust plate 2
Inside edge be provided with the fixture block 4 that bends to the inside, fixture block 4 is caught in after neck and is articulated on hangers.In the program, pass through fixture block 4
Positioned with groove, limitation thrust plate and bent axle transfer.
As a kind of preferred embodiment, neck and fixture block 4 are respectively three, and thrust plate 2 is with main bearing shell 1 in intermediate position points
It is welded together.
In such scheme, thrust plate 2 and main bearing shell 1 are spot-welded together, can effectively prevent thrust bearing shell during the supply of material in stream
Come off in turning, thrust plate 2 is disengaged with main bearing shell 1 after assembling, and thrust plate 2 is diametrically hooked together with main bearing shell 1, thrust plate
2 is movable in the axial direction with main bearing shell 1, and bent axle can be effectively solved in the axially free activity of bent axle in limited space
The problem of thrust plate flatness is poor, so as to increase effective contact area of bent axle and thrust plate 2.
To sum up, the thrust bearing shell structure of the present embodiment, as the thrust plate 2 and main bearing shell 1 of fabricated part, is welded in vanning
Being connected together to move freely, and effectively thrust bearing shell can be prevented to be come off in circulation.Main bearing shell 1 and thrust plate after assembling
2 are disengaged, and thrust plate 2 can axially be moved freely in bent axle, the problem of thrust bearing shell flatness is poor are effectively solved, so as to increase
Plus effective contact area of bent axle and thrust plate, the abrasion of thrust plate is reduced, the reliability of engine is improved.
The foregoing description to specific illustrative embodiment of the present utility model be in order to illustrate and illustration purpose.These
Description is not wishing to being defined to the utility model into disclosed precise forms, and it will be apparent that according to above-mentioned teaching, can carry out
It is many to change and change.The purpose of selecting and describing the exemplary embodiment is that explaining certain principles of the present utility model
And its practical application, so that those skilled in the art can realize and utilize a variety of examples of the present utility model
Property embodiment and a variety of selections and change.Scope of the present utility model is intended to by claims and its waits similar shape
Formula is limited.
