Abstract
The utility model provides the positioning leak-proof oil structure of a kind of floating bearing and intermediate, including machine core, intermediate, two floating bearings, gasket, axle envelope cover surely.Wherein, the intermediate is socketed on the machine core, two floating bearing is arranged between the machine core and the intermediate and is respectively adjacent in pressure shell, volute, two floating bearing is covered by the gasket, the axle envelope respectively with pressure shell end, volute end to fix surely, and the intermediate is provided with boss on the side of two floating bearing.The positioning leak-proof oil structure of a kind of floating bearing and intermediate provided by the utility model is fixed by being covered surely by gasket, axle envelope respectively in two floating bearings with pressure shell end, volute end, and gasket and axle envelope can play better effect to the cooperation lubrication of two floating bearings and machine core, intermediate surely, to prevent the oil leakage phenomenon of pressure, volute end.
Description
Technical field
The utility model relates to a kind of turbocharger, and in particular to a kind of positioning leak-proof oil of floating bearing and intermediate
Structure.
Background technique
Turbocharger is actually a kind of air compressor, increases air inflow by compressed air.It is to utilize hair
The exhaust gas inertia impulsive force of motivation discharge pushes the indoor turbine of turbine, and turbine drives coaxial impeller again, impeller force feed is by sky
The air that air cleaner pipeline is sent is allowed to pressurization and enters cylinder.Currently, the floating bearing in turbocharger is that both sides are used
Retaining ring is fixed on middle body, prevents the play of floating bearing axial direction.This assembly method uses 4 small retaining rings, in assembling process
Be easily lost, need specific purpose tool that can just dismount, the requirement of this assembly completely can with another new construction come
Instead of.
Utility model content
The utility model provides the positioning leak-proof oil structure of a kind of floating bearing and intermediate, to solve prior art presence
Floating bearing fixed and cause more than components and the problem of dismounting needs tool with multiple retaining rings.
In order to solve the above technical problems, the utility model provides the positioning leak-proof oil knot of a kind of floating bearing and intermediate
Structure, including machine core, intermediate, two floating bearings, gasket, axle envelope cover surely.Wherein, the intermediate is socketed on the machine core,
Two floating bearing is arranged between the machine core and the intermediate and is respectively adjacent to floating in pressure shell, volute, described two
Dynamic bearing is covered by the gasket, the axle envelope respectively with pressure shell end, volute end to fix surely, and the intermediate is adjacent to described
Boss is provided on the side of two floating bearings.
Preferably, the axle envelope covers generally cyclic structure surely and there is step in outer surface, forms front half section thickness and second half section
Thin structure.
The utility model bring is the utility model has the advantages that the positioning of a kind of floating bearing provided by the utility model and intermediate is anti-
Oil leak structure is fixed by being covered surely by gasket, axle envelope respectively in two floating bearings with pressure shell end, volute end, and gasket and
Axle envelope can play better effect to the cooperation lubrication of two floating bearings and machine core, intermediate surely, to prevent pressure, whirlpool
The oil leakage phenomenon at shell end.

Fig. 2 is the structural schematic diagram of a-quadrant in Fig. 1 according to the utility model embodiment.
Fig. 3 is to determine nested structure schematic diagram according to the gasket and axle envelope of the utility model embodiment.
Wherein, 1- machine core, 2- intermediate, 3- floating bearing, 4- gasket, 5- axle envelope cover surely, 6- boss.
Specific embodiment
To keep the purpose of this utility model, technical solution and advantage clearer, below in conjunction with drawings and the specific embodiments,
The utility model is described in further detail.
As shown in Figure 1, the positioning leak-proof oil structure of a kind of floating bearing provided by the utility model and intermediate, including machine
Core 1, intermediate 2, two floating bearings 3, gasket 4, axle envelope cover 5 surely.Wherein, the intermediate 2 is socketed on the machine core 1, institute
Two floating bearings 3 are stated to be arranged between the machine core 1 and the intermediate 2 and be respectively adjacent to floating in pressure shell, volute, described two
Dynamic bearing 3 with pressure shell end, volute end covers 5 by the gasket 4, the axle envelope respectively to fix surely, both can be to two floating axles
It holds 3 and plays positioning, and better effect can be played to the cooperation lubrication of two floating bearings 3 and machine core 1, intermediate 2, from
And prevent the oil leakage phenomenon of pressure, volute end.
The intermediate 2 is provided with boss 6 on the side of two floating bearing 3, it is possible to reduce washer herein
Usage quantity or do not use washer directly and and even if need to equip washer herein to reduce the part of machine core assembly
Specific purpose tool is not needed to be dismounted yet.Under the premise of meeting machine core assembly use, optimizes original assembly method, reduce
The process of assembly reduces manufacturing cost.
Furthermore, it is understood that the axle envelope covers 5 generally cyclic structure and outer surfaces surely a step, formed front half section it is thick and after
Half section of thin structure.
In conclusion the positioning leak-proof oil structure of a kind of floating bearing provided by the utility model and intermediate passes through two
Floating bearing is covered by gasket, axle envelope respectively with pressure shell end, volute end to fix surely, and gasket and axle envelope surely can be floating to two
The cooperation lubrication of dynamic bearing and machine core, intermediate plays better effect, to prevent the oil leakage phenomenon of pressure, volute end.
The above description is only the embodiments of the present invention, is not intended to limit the utility model, for this field
Technical staff for, various modifications and changes may be made to the present invention.Within the spirit and principle of the utility model,
Any modification, equivalent replacement, improvement and so on should be included within the scope of the claims of the utility model.
