Rotor.
Background technology
High-speed electric expreess locomotive typically refers to the rotating speed motor more than 10000r/min, and its rotating speed is high, power of motor
Density is big, but the middle slowspeed machine that its physical dimension is identical much smaller than output, therefore can be effective
Save material；The rotary inertia of high-speed electric expreess locomotive is less simultaneously, and therefore dynamic response is very fast, and High-speed Electric
Machine can be joined directly together with prime mover or load, eliminates traditional mechanical variable speed device, is effectively reduced and sets
Standby floor space and reduction noise, improve transmission system efficiency.High-speed electric expreess locomotive research at present has become international
The study hotspot of electrical field, and it is fully applicable to high speed grinding machine and other machining tools, high speed flywheel storage
The high speed centrifugation compressor used in energy system, natural gas conveying and sewage disposal and aerator etc..In recent years
Coming along with Technologies in Petrochemical Industry high speed development, the capacitance grade of petrochemical equipment improves year by year so that be used for driving
The pot-motor of dynamic compressor class have also been obtained good opportunity to develop.Especially with domestic manufacture
The development of technology and the progress of manufacturing process, originally many technical barriers of restriction high-speed electric expreess locomotive development are able to
Capture and solve, and the design of the in good time high-speed electric expreess locomotive carried out under novel manufacturing process just seems with developing
The most urgent.
Conventional motor rotor is owing to its power density is little, physical dimension big and needs traditional mechanical speed change
The features such as device, cause that it is big in engineer applied process tabulating equipment floor space, noise big, power train
The shortcomings such as system efficiency is low.But along with the development of modern electrical machine industry, the requirement for motor speed more comes
The highest, conventional lamination armature has been difficult to bear centrifugal force produced by high speed rotating, it is therefore desirable to suitable
Time design and development of new high speed rotor of motor to adapt to the development of modern industry.
Summary of the invention
In order to solve the relevant issues in existing conventional motor rotor application process, the present invention provides a kind of use
In the miniature high-speed rotor of driving compressor, this rotor disclosure satisfy that rotor is at high speeds
Run, and the middle slowspeed machine that its physical dimension is identical much smaller than output, there is rotary inertia little,
Dynamic response is fast, the feature such as transmission efficiency height, good stability.
The present invention solve its technical problem the technical scheme is that described rotor include one solid
Rotating shaft and 12 rotor cage bars, rotor cage bar is uniformly distributed along solid spindle circumference, solid spindle with turn
Connected as one by three U-shaped attachment welds between sub-cage bar.
Comparing the rotor of routine, the present invention uses solid spindle and T2 copper bar by solder design
Mode realizes, described rotor cage bar 2, rotor cage bar 6, rotor cage bar 10 and the group of solid spindle
Dress gap respectively is 0.05mm, 0.10mm and 0.15mm, described rotor cage bar 3, rotor cage bar 7,
After rotor cage bar 11 assembles with solid spindle, cage bar highlights the height on rotating shaft surface and is followed successively by 0mm, 0.5mm
And 1mm, described rotor cage bar 4, rotor cage bar 8, rotor cage bar 12 and the table of solid spindle faying face
Surface roughness controls in 0.8 μm, 1.0 μm and 1.2 μm respectively, described rotor cage bar 5, rotor cage bar 9,
Between rotor cage bar 13 and solid spindle, faying face is taked to be not added with intermediate layer, add in the middle of Ni base successively
Layer, interpolation Ag base intermediate layer are attached.
The invention provides a kind of miniature high-speed rotor for driving compressor, it is at high speed rotating
During can bear the operating on centrifugal force that conventional laminated rotor is difficult to bear, simultaneously because use whole
Copper bar, its electric conductivity is also compared convention rotor and is greatly improved.
