Description
Technical field
The utility model belongs to airplane structural parts field, is related to hole axle part is coordinated with the improvement of lubricant effect.
Background technology
In airplane structural parts, when the axle of miscellaneous part is connected with airframe structure, for preventing between axle and airframe structure
Wear and tear, bushing is installed generally between axle and airframe structure part.At present, part bushing does not have oil groove it is impossible to abundant fill
Lubricating oil to rotary shaft surface, part bushing has linear pattern oil groove although lubricating oil can be made to enter into the surface of axle, but no
Method ensures that lubricating oil can reach all positions in axle surface, and when later maintenance needs the outer surface make-up oil to axle, axle
Gap and bushing between is less, and the lubricating oil being filled by oil filler point cannot be completely attached to the outer surface of axle, leads to lubricate
Effect is undesirable.
Utility model content
The purpose of this utility model there are provided a kind of new inside spin oil groove bushing, the outer surface for axle and lubrication
Oil energy comprehensive engagement, reaches good lubricant effect.
The purpose of this utility model is achieved through the following technical solutions：A kind of inside spin oil groove bushing, described inside spin oil
The axial end that slot liner covers for side is radially provided with the tubular of annular flange, in described inside spin tank car lining tackling
There is described flange side to have a circle chamfering along inwall radial direction, described inside spin oil groove bushing inwall is provided with a plurality of equal
The helical oil groove of even distribution.
Preferably, the starting point of described helical oil groove is located at described inside spin oil groove bushing side end face, described spiral
The terminal of shape oil groove is located at another side end face of described helical oil groove bushing.
Preferably, described helical oil groove is 3.
Preferably, described helical oil groove is semicircle along the section of described inside spin oil groove bushing axial direction.
Preferably, the groove depth of described helical oil groove is thickness between described inside spin oil groove bushing inwall and outer wall
1/4 to 1/3.
Preferably, the pitch of described helical oil groove is the half of described inside spin oil groove liner sleeve length.
Inside spin tank car lining set provided by the utility model has the beneficial effects that, can rapidly pass the lubricating oil of injection
Transport to the surface of axle, and cover uniformly, oil groove is easy to process, low cost.

Specific embodiment
For making purpose, technical scheme and advantage that the utility model is implemented clearer, below in conjunction with the utility model
Accompanying drawing in embodiment, is further described in more detail to the technical scheme in the utility model embodiment.In the accompanying drawings, ad initio
To the element that same or similar label represents same or similar element or has same or like function eventually.Described reality
Applying example is a part of embodiment of the present invention, rather than whole embodiments.Embodiment below with reference to Description of Drawings is to show
Example property it is intended to be used for explaining the utility model, and it is not intended that to restriction of the present utility model.Based in the utility model
Embodiment, the every other embodiment that those of ordinary skill in the art are obtained under the premise of not making creative work,
Broadly fall into the scope of the utility model protection.
Below in conjunction with the accompanying drawings the utility model inside spin oil groove bushing is described in further details.
The inside spin oil groove bushing 1 that the utility model provides, for rapidly transmitting the lubricating oil of injection to the table of axle
Face, enables the surface of axle and lubricating oil comprehensive engagement to lubricate.As shown in figure 1, inside spin oil groove bushing 1 is the axial end of side
Radially it is provided with the tubular of annular flange 11, there is flange 11 side along inwall radially in inside spin oil groove bushing 1
Direction has a circle chamfering, and this chamfer angle selects conventional 45° angle, inside spin oil groove bushing 1 inwall is provided with a plurality of equal
The helical oil groove 12 of even distribution, preferably 3 requirements that can meet uniform fold axle surface, the starting point of this helical oil groove 12
Selection is arranged inside spin oil groove bushing 1 one side end face, and terminal selects to be arranged at another side end face of inside spin oil groove bushing 1,
As shown in Fig. 2 this helical oil groove 12, along the cross sectional shape preferably semicircle of inside spin oil groove bushing 1 axial direction, also may be used
For other with groove shape such as V-shaped, U-shaped, the groove depth prioritizing selection of semicircle helical oil groove 12 is equal to inside spin oil groove
The 1/4 to 1/3 of thickness between bushing 1 inwall and outer wall, groove is too shallow, and lubricants capacity lubricates insufficient very little, and groove is too deep, storage
The lubricating oil deposited excessively causes to waste, and the pitch of semicircle helical oil groove 12 is according to inside spin tank car lining of the present utility model
The length of set suitably adjusts, and the pitch prioritizing selection of the helical oil groove 12 of the present embodiment is inside spin oil groove bushing 1 length
Half, thus the utility model can lubricating oil cover uniformly, and semicircle helical oil groove 12 is easy to process, low cost
Honest and clean.
The above, specific embodiment only of the present utility model, but protection domain of the present utility model does not limit to
In this, any those familiar with the art in the technical scope that the utility model discloses, the change that can readily occur in
Change or replace, all should cover within protection domain of the present utility model.Therefore, protection domain of the present utility model should be with described
Scope of the claims is defined.
