Description
Technical field
The invention belongs to a kind of air turbine device, and in particular to a kind of high-speed permanent magnetic body magnetic-suspension main-shaft air force is driven
Dynamic device.
Background technology
High-speed main spindle is commonly utilized in industry, its performance such as metal cutting, PCB punchings and directly affects product quality, at a high speed
Main shaft is different according to bearing type, can be divided into mechanical main shaft, air-floating main shaft, oil film main shaft, magnetic-suspension main-shaft etc.；Traditional contact
There is Mechanical Contact in formula main shaft, rotating speed is relatively low, and mechanical wear is big, high energy consumption, and short life is, it is necessary to the shortcomings of lubricating, with processing
Raising of the industry to speed of mainshaft demand, great challenge is proposed to motor frequency conversion and cooling, limits entering for the speed of mainshaft
One step improves.
The content of the invention
In order to solve the above problems, the invention provides a kind of driving of high-speed permanent magnetic body magnetic-suspension main-shaft air force to fill
Put, driving force can be provided for high-speed permanent magnetic body magnetic-suspension main-shaft.
The object of the present invention is achieved like this：A kind of high-speed permanent magnetic body magnetic-suspension main-shaft air power drive device, bag
The rotor main shaft of permanent magnet magnetic suspension is included, spiral case is cased with the outside of described rotor main shaft, impeller is placed in spiral case, and impeller is with turning
Sub- main shaft is fixedly connected, and described spiral case is provided with one or more pairs of axisymmetric nozzles, while spiral case is provided with a pair or more
To the exhaust outlet of axisymmetric radial direction.
The present invention also has following technical characteristic：
1st, described impeller is deformation impact formula turbo blade.
2nd, it is provided with multigroup magnetic sheet in the inner chamber of described rotor main shaft.
3rd, described nozzle is daraf(reciprocal of farad) that nozzle of air supply.
The present invention has the advantages that and advantage：The present apparatus can run to very high rotating speed, small with mechanical wear,
Energy consumption is low, long lifespan, and the advantages that without lubricating, permanent magnet magnetic suspension main shaft not only has whole features of magnetic-suspension main-shaft, and
And the heart can be returned automatically, without active control, greatly simplify the structure of magnetic-suspension main-shaft, air impeller use high pressure gas for
Driving force, as long as Impeller Design is reasonable, the limitation of no maximum speed, and caused heat is taken away with air-flow, without cooling,
Simple in construction, processing cost is low, has preferable application prospect in high-speed main spindle field.
