Description
Technical field：
The present invention relates to a kind of novel static pressure air-flotation electric spindles, belong to technical field of mechanical processing.
Background technology：
Existing most of static pressure air-bearing electro spindles are all made of main shaft and fix, the single way of output of shaft core rotation, gas
Body channel, cooling-water duct are opened on main shaft, processing difficulties and heat dissipation effect is bad.In the course of work of electro spindle
In, axle core component fever is serious, and copper sheathing is heated to be expanded outwardly, be susceptible to air-bearing component, lower air-bearing component with
The phenomenon that axle core component gap becomes larger even results in electro spindle locking.Air-bearing is generally shorter, and main shaft is longer, shaft core
So that centroid adjustment is difficult, concentricity cannot ensure well for rotation, and in the case, the radial side of main shaft pushes away bearing capacity point
Cloth is uneven or part shaft part cannot get air supporting support, is easy to cause the unstable of main shaft or even occurs sweeping wound, stuck phenomenon,
The performances such as rotating accuracy, dynamic stiffness to make electro spindle are poor.
Invention content：
It is an object of the present invention to：There is provided a kind of shaft core fix, more supporting section static pressure air-bearing electro spindles of main shaft rotation, it is rich
The rich way of output of electro spindle, multistage air-bearing provides more supporting surfaces and improves the stability of electro spindle to be carried with radial
Power.
In order to realize the purpose of the present invention, intend using following technical scheme：
The present invention includes：Shaft core, ring flange, flange fixing screws, main shaft, left axle sleeve, left axle sleeve fixing screws, gas supply
Road, rotor, rotor fixing screws, motor stator, right axle sleeve, right axle sleeve fixing screws, end cap, end cap fixing screws, the right side
Exhaust duct, cooling water inlet channel, cooling water outlet road, left bank air flue, radial flow controller, axial throttle orifice, it is characterised in that：Described
Air supply duct, right exhaust duct, cooling water inlet channel, cooling water outlet road, left bank air flue, radial flow controller and axial throttling are equipped in shaft core
Hole, air supply duct are connected to radial flow controller with axial throttle orifice, and radial flow controller includes radial throttle orifice and tangential throttle orifice, right
The outlet of exhaust duct and left bank air flue and atmosphere, ring flange are fixed by flange fixing screws with main shaft, left axle sleeve, electricity
Machine rotor, right axle sleeve are fixed to main shaft by left axle sleeve fixing screws, rotor fixing screws, right axle sleeve fixing screws respectively
On, end cap is fixed by end cap fixing screws with main shaft, and when work, above-mentioned shaft core is fixed, ring flange, main shaft,
Left axle sleeve, right axle sleeve and end cap are fixed to each other and are rotated around shaft core.
The features of the present invention：
The present invention changes existing electro spindle shaft core torque output pattern by the way of main shaft rotation；Electro spindle master
Axis body rotates, it is easier to carry out centroid adjustment；Electro spindle is axially arranged with multiple bearing sections, forms multi-segment bearing surface, improves electricity
The stability of main shaft and radial bearing capacity；Radial flow controller generates air film by radial, tangential throttle orifice respectively, both can guarantee low
Bearing capacity when fast can reduce circular runout again, improve the stability of electro spindle.
