Abstract
The utility model discloses a turbo charger's semifloating bearing assembly structure, it includes midbody and semifloating bearing, be provided with the pilot hole in the midbody, wherein, the appearance of semifloating bearing adopts the toper structure, the pilot hole is the cooperation the bell mouth of semifloating bearing, just the one end of semifloating bearing is inserted in the pilot hole and through conical surface auto -lock in in the pilot hole, the other end carries on spacingly through spacing subassembly. Above -mentioned turbo charger's semifloating bearing assembly structure's semifloating bearing and pilot hole adopt the cone combined with design, and the friction that calculates that material coefficient of friction through bearing and midbody can be accurate from the locking angle, by correctly define the cone angle from the locking angle, guarantees that the cooperation reaches the auto -lock requirement, prevents effectively that the bearing from rotating, simple structure not only, easy realization, and reduced rotor radial swinging amplitude, reduce vibrations and counterbalance to can improve rotor efficiency.
Description
Technical field
This utility model is related to a kind of turbocharger, assembles more particularly, to a kind of semifloating bearing of turbocharger
Structure.
Background technology
Semifloating bearing is provided between the intermediate of turbocharger and rotating shaft.At present, conventional semifloating bearing is equal
It is this simple and practical for ring-shaped cylinder structure, but for endoporus and rotating shaft coordinate in high speed motions, due to bearing
There is gap between intermediate, so rotor dynamic balancing can be affected, and the swing vibrations of rotor can be increased, rotor is caused
Damage.
Utility model content
The purpose of this utility model is the semifloating bearing assembling structure for providing a kind of turbocharger, and it has structure
Simply, the characteristics of reducing rotor radial wobble amplitude and improve rotor efficiency, to solve prior art in turbocharger half
The problems referred to above that floating bearing is present.
It is that, up to this purpose, this utility model is employed the following technical solutions：
A kind of semifloating bearing assembling structure of turbocharger, it includes intermediate and semifloating bearing, the centre
Pilot hole is provided with vivo, wherein, the profile of the semifloating bearing adopts pyramidal structure, the pilot hole to be cooperation described half
The dress is locked in the bellmouth of floating bearing, and one end insertion pilot hole of the semifloating bearing and by the conical surface certainly
In distribution, the other end is carried out spacing by limit assembly.
Especially, the limit assembly includes the stopper slot being opened in the pilot hole, is provided with the stopper slot
Circlip, the end face that the circlip is resisted against the semifloating bearing is spacing to its.
The beneficial effects of the utility model are that the semifloating bearing assembling of the turbocharger compared with prior art is tied
The semifloating bearing and pilot hole of structure is designed using cone match, and conical surface left side diameter is little, and right side diameter is big, by bearing with
The material friction coefficient of mesosome can accurately calculate friction self-locking angle, and by Self-locking angle cone angle is correctly defined, it is ensured that cooperation reaches
To self-locking requirement, effectively prevent bearing from rotating, and cone match can be good at centering, and this cooperation eliminates bearing with
The gap of mesosome, rotor is only left the cooperation of axle and bearing.It is not only simple in structure, it is easy to accomplish；And reduce rotor radial
Wobble amplitude, reduces vibrations and aequum, and can improve rotor efficiency.
Description of the drawings
Fig. 1 is the knot of the semifloating bearing assembling structure of the turbocharger that this utility model specific embodiment 1 is provided
Structure schematic diagram.
Specific embodiment
Further illustrate the technical solution of the utility model below in conjunction with the accompanying drawings and by specific embodiment.
Refer to shown in Fig. 1, Fig. 1 is the semifloating axle of the turbocharger that this utility model specific embodiment 1 is provided
Take up the structural representation of distribution structure.
In the present embodiment, a kind of semifloating bearing assembling structure of turbocharger includes intermediate 1 and semifloating bearing
2, be provided with pilot hole in the intermediate 1, the profile of the semifloating bearing 2 adopts pyramidal structure, the pilot hole be with
Close and opened up on the outside of the big one end of the diameter of semifloating bearing 2 in the bellmouth of the semifloating bearing 2, the pilot hole
Limited location groove 3, is provided with the stopper slot 3 for the spacing circlip 4 of double floating bearing 2, and the circlip 4 is supported
The end face for being against the semifloating bearing 2 is spacing to its.
Designed using cone match between the semifloating bearing 2 and the pilot hole of intermediate 1, conical surface left side diameter is little,
Right side diameter is big, and by the material friction coefficient of semifloating bearing 2 and intermediate 1 friction self-locking angle can be accurately calculated,
Cone angle is correctly defined by Self-locking angle, it is ensured that cooperation reaches self-locking requirement, effectively prevents bearing from rotating, and cone match can be very
Good centering, providing thrust by circlip 4 makes the cooperation of semifloating bearing 2 and intermediate 1 reach self-locking, and this cooperation disappears
Except bearing and the gap of intermediate, rotor is only left the cooperation of axle and bearing, reduces rotor radial wobble amplitude, reduces shake
Dynamic and aequum, and rotor efficiency can be improved.
Above example simply elaborates ultimate principle of the present utility model and characteristic, and this utility model does not receive above-mentioned example
Limit, on the premise of without departing from this utility model spirit and scope, this utility model also has various change and change, these changes
Change and change and both fall within the range of claimed this utility model.The claimed scope of this utility model will by appended right
Ask book and its equivalent thereof.
