Description
Technical field
The utility model relates to a kind of coupling, specifically a kind of coupling of High Rotation Speed.
Background technique
High-speed electric expreess locomotive typically refers to rotating speed more than the motor of 10000rpm and generator, has rotating speed high, specific power is large, volume is little, lightweight, rotary inertia is little, the features such as dynamic response is very fast, directly can be connected with high-revolving load or prime mover, thus eliminate traditional mechanical variable speed device, both reduced equipment volume, turn avoid the loss that variable speed drive causes, vibration, noise, the impacts such as fault, improve the operational efficiency of transmission system, running precision and reliability, therefore, the application in civil and military field is more and more extensive, as scientific research and industrial turbulent flow micro-nano disintegrating apparatus, turbomolecular pump, High-Speed Flywheel Energy Storage System, the high-speed centrifuge of bioengineering, the high speed electric dental drill of medical apparatus, the spindle motor of machine tool industry, high-speed drilling machine, high speed grinding machine, the high speed centrifugal pump of Aero-Space, the high speed centrifugation compressor and the blower that use in natural gas transport and sewage treatment and be directly connected to form power generation system with miniature gas turbine, be widely used in distributed power supply system and portable field of power supplies.
And in all applications, the articulation issues of high-speed electric expreess locomotive and load or prime mover all must be solved, this just requires to study the reliable coupling adapted with high rotating speed.Traditional rigid coupling centering is poor, is generally used for that rotating speed is not high, the stable occasion of load; Non-metal elastic element immunity coupling is not suitable for high speed situation yet; The cost of diaphragm coupling is higher, volume is comparatively large, and there is no the ripe coupling that can be applicable to more than rotating speed 40000rpm.
Model utility content
The purpose of this utility model is to provide that a kind of compact structure, precision are high, good reliability, easy for installation, can be used for more high-revolving coupling.
To achieve these goals, mode of execution of the present utility model devises a kind of coupling, comprises the first axle sleeve be connected with electric machine main shaft and the second axle sleeve be connected with prime mover main shaft;
Wherein, described first axle sleeve and described second axle sleeve are interconnected, and described first axle sleeve is welded by electron beam with the joint of described second axle sleeve.
Mode of execution of the present utility model in terms of existing technologies, not only little, the compact structure of volume, and coupling first axle sleeve and the second axle sleeve are owing to being adopt the mode of electron beam welding to weld, thus coupling can be enable to bear larger load, thus guarantee that coupling can be applied in the higher occasion of rotating speed.
Further, in described first axle sleeve, being provided with the first spline housing for clamping described electric machine main shaft, in described second axle sleeve, being provided with the second spline housing for clamping described prime mover main shaft.In application process, electric machine main shaft and prime mover main shaft can be locked electric machine main shaft and prime mover main shaft respectively by the spline housing in the spline housing in the first axle sleeve and the second axle sleeve, respectively to complete the connection to diaxon.
Further, one end outwardly convex that described first axle sleeve connects described second axle sleeve forms the first lip part, and one end outwardly convex of relatively described first axle sleeve of described second axle sleeve forms the second lip part connecting described first lip part; Wherein, the end face of described second lip part has part to be excavated the ring-type thin walled structures of formation one with cavity, and the outer rim of described first lip part has part from end face, inwardly shrink the lug boss being formed and insert in described second lip part cavity.The second lip part due to coupling second axle sleeve is the thin walled structures of a ring-type, in the process of practical application, out-of-alignment error when connecting with prime mover by bending automatic absorption high-speed electric expreess locomotive, coaxality during both guarantees High Rotation Speed, and by adopting the rational stress design of sheet-like structure and Material selec-tion, the first axle sleeve of coupling and front and back two-part can be made when breaking down to hightail, thus ensure high-speed electric expreess locomotive and the Security of prime mover when running up.
Accompanying drawing explanation
Fig. 1 is the structural representation of the coupling of the utility model first mode of execution.
Embodiment
For making the purpose of this utility model, technological scheme and advantage clearly, below in conjunction with accompanying drawing, each mode of execution of the present utility model is explained in detail.But, persons of ordinary skill in the art may appreciate that in each mode of execution of the utility model, proposing many ins and outs to make reader understand the application better.But, even without these ins and outs with based on the many variations of following mode of execution and amendment, each claim of the application technological scheme required for protection also can be realized.
First mode of execution of the present utility model relates to a kind of coupling, as shown in Figure 1, comprises the first axle sleeve 1 be connected with electric machine main shaft and the second axle sleeve 2 be connected with prime mover main shaft.Wherein, the first axle sleeve 1 and the second axle sleeve 2 are interconnected, and the first axle sleeve 1 is welded by electron beam with the joint of the second axle sleeve 2.
Be not difficult to find by foregoing, the not only volume of whole coupling is little, compact structure, and coupling first axle sleeve 1 and the second axle sleeve 2 are owing to being adopt the mode of electron beam welding to weld, thus coupling can be enable to bear larger load, thus guarantee that coupling can be applied in the higher occasion of rotating speed.
In addition, in the present embodiment, in the first axle sleeve 1, being provided with the first spline housing 1-1 for clamping motor main shaft, in the second axle sleeve 2, being provided with the second spline housing 2-1 for clamping prime mover main shaft.In application process, electric machine main shaft and prime mover main shaft can be locked electric machine main shaft and prime mover main shaft respectively by the spline housing 2-1 in the spline housing 1-1 in the first axle sleeve 1 and the second axle sleeve 2, respectively to complete the connection to diaxon.
In addition, it is worth mentioning that, in the present embodiment, one end outwardly convex that the first axle sleeve 1 connects the second axle sleeve 2 forms the first lip part 1-2, and one end outwardly convex of relative first axle sleeve 1 of the second axle sleeve 2 forms the second lip part 2-2 of connection first lip part 1-2.Wherein, the end face of the second lip part 2-2 has part to be excavated the ring-type thin walled structures of formation one with cavity 2-3, and the outer rim of the first lip part 1-2 has part from end face, inwardly shrink the lug boss 1-3 formed in insertion second lip part cavity 2-3.The second lip part 2-2 due to coupling second axle sleeve is a ring-type thin walled structures, in the process of practical application, out-of-alignment error when connecting with prime mover by bending automatic absorption high-speed electric expreess locomotive, coaxality during both guarantees High Rotation Speed, and by adopting the rational stress design of sheet-like structure and Material selec-tion, the first axle sleeve of coupling and front and back two-part can be made when breaking down to hightail, thus ensure high-speed electric expreess locomotive and the Security of prime mover when running up.
Persons of ordinary skill in the art may appreciate that the respective embodiments described above realize specific embodiment of the utility model, and in actual applications, various change can be done to it in the form and details, and do not depart from spirit and scope of the present utility model.
