Abstract
The utility model provides a kind of multi-function coupling, is located at for connecting front and back two sections of axis, and at assembly between former two sections of axis.The shaft coupling is flexible shaft (1), and is multi-diameter shaft, the set tooth that assembly is engaged with two sections of axis is both provided in the inside cylinder of the flexibility multi-diameter shaft and the leading portion of outside cylinder, by covering tooth torsion pass.The outside cylinder back segment of flexible multi-diameter shaft is provided with the precision cylindrical face for assembling bearing (2) fulcrum, by fulcrum and leading portion decoupler shaft, ensures that the operating of fulcrum is stablized.Simultaneously in order to limit the sliding of bearing (2) in an axial direction, in face of the flexible multi-diameter shaft mixed lateral column after be provided with annular flange between two sections.Multi-function coupling provided by the utility model plays the role of flexible clutch, and improves the stability of fulcrum, can reduce forward and backward two sections of vibration coupling, suitable for needing the operating mode of stable, high-speed drive.
Description
Technical field
The utility model belongs to aero-engine field of structural design, and in particular to a kind of multi-function coupling.
Background technology
Connection, the torsion pass of two sections of axis need reliable power transmission and with certain assembly redundancies.Existing program is two sections
Directly pass through mutual set tooth torsion pass, cylindrical surface cooperation positioning between the axis connected together.Fulcrum is located on leading portion axis, this
The coupler structure of form is simple, but requires two sections of axis assembly axis concentricities high, and rigidity is larger, and fulcrum is filled by two sections of axis
The offset affect match, processed, vibration increase when being easy to cause axis operating.
Utility model content
The purpose of this utility model is to provide a kind of multi-function couplings, overcome or alleviated by at least one of the prior art
Drawbacks described above.
The purpose of this utility model is achieved through the following technical solutions：A kind of multi-function coupling, be set to two sections of axis it
Between, which is flexible shaft, is provided with the set tooth for engage and assembling with two sections of axis inside and outside the flexible shaft on two cylinders.
Preferably, the cylindrical surface for assembling bearing pivot is provided on the flexible shaft.
Preferably, the annular flange to slide axially for limiting the bearing is provided on the flexible shaft.
A kind of advantageous effect of multi-function coupling provided by the utility model is, that is, plays the work of flexible clutch
With, and the stability of fulcrum is improved, forward and backward two sections of vibration coupling can be reduced, suitable for needing the operating mode of stable, high-speed drive.
Description of the drawings
Fig. 1 is the structural schematic diagram of the utility model multi-function coupling.
Reference numeral：
1- flexible shafts, 2- bearings.
Specific implementation mode
To keep the purpose, technical scheme and advantage that the utility model is implemented clearer, below in conjunction with the utility model
Attached drawing in embodiment, is further described in more detail the technical scheme in the embodiment of the utility model.In the accompanying drawings, from beginning
Same or similar element or element with the same or similar functions are indicated to same or similar label eventually.Described reality
It is the utility model a part of the embodiment to apply example, instead of all the embodiments.Below with reference to the embodiment of attached drawing description
It is exemplary, it is intended to for explaining the utility model, and should not be understood as limiting the present invention.It is new based on this practicality
Embodiment in type, the every other implementation that those of ordinary skill in the art are obtained without creative efforts
Example, shall fall within the protection scope of the present invention.
The multi-function coupling of the utility model is described in further details below in conjunction with the accompanying drawings.
As shown in Figure 1, a kind of multi-function coupling, be located at for connecting front and back two sections of axis, and at assembly former two sections of axis it
Between.The shaft coupling be flexible shaft 1, and be multi-diameter shaft, the flexibility multi-diameter shaft inside cylinder and outside cylinder leading portion (i.e.
Left side in Fig. 1) it is both provided with the set tooth that assembly is engaged with two sections of axis, by covering tooth torsion pass.In the outside cylinder of flexible multi-diameter shaft
Back segment is provided with the precision cylindrical face for assembling 2 fulcrum of bearing, by fulcrum and leading portion decoupler shaft, ensures that the operating of fulcrum is steady
It is fixed.Simultaneously in order to limit the sliding of bearing 2 in an axial direction, in face of the flexible multi-diameter shaft mixed lateral column after be provided with convex annular between two sections
Edge.The multi-function coupling increases assembly redundancy, increases fulcrum flexibility, while improving rotor operating reliability.
Above description is only a specific implementation of the present invention, but the scope of protection of the utility model is not limited to
In this, any one skilled in the art within the technical scope disclosed by the utility model, the change that can be readily occurred in
Change or replace, should be covered within the scope of the utility model.Therefore, the scope of protection of the utility model should be with described
Subject to scope of the claims.
