Specific embodiment
Embodiment 1
The implementation of the utility model is as follows: a kind of air cooling air bearing motor shaft structure is as shown in Fig. 1 and Fig. 2, Fig. 1 exhibition
The air bearing gas circuit of motor shaft is shown, high pressure gas enters main shaft shell longitudinal direction air bearing air flue 3 by air bearing gas air inlet 5, then leads to
Cross transverse air channel 11 and air-bearing longitudinal direction air bearing air flue 8 that main shaft shell transverse direction air bearing air flue 2 enters air-bearing, high pressure gas
Body forms one layer of air film between air-bearing 10 and motor shaft 12, while also forming one between motor stator 7 and motor shaft 12
Layer air film realizes the rotation of motor shaft High speed and low resistance power.
As Fig. 2 illustrates the structure chart of cooling gas circuit: high pressure gas enters from cooling air air inlet 17 by vortex groove 18, whirlpool
High pressure gas is divided into cold air and hot gas by the vortex tube that flow tube pipe shaft, cooling fin and pressure regulator valve are constituted, vortex tube, and cold air passes through whirlpool
Chute centre bore 182 enters the first main shaft shell longitudinal direction cooling air air flue 16 and the first main shaft shell transverse direction cooling air air flue 15,
Again by the cooling air-bearing 10 of main shaft shell spiral cooling airway 22, then it is laterally cold to pass through the second main shaft shell again for cooling air
But gas air flue 23 and the second main shaft shell longitudinal direction cooling air air flue 24 enter motor housing spiral cooling airway 25 and 26 structure of outer cover
At cooling space, main shaft is discharged finally by cooling air exhaust outlet 28 in the motor of cooling main shaft.The tune that hot gas passes through vortex tube
Main shaft is discharged in pressure valve 21.Realize the cooling of main shaft air-bearing and motor.
The structure of vortex tube is as shown in figure 3, its working principle is that high pressure gas at normal temperature by cooling air air inlet enters whirlpool
The high-pressure space that chute 18 and main shaft shell 9 are constituted, the high pressure gas in the space can enter from 181 high speed of skewed slot of vortex tube
Vortex tube pipe shaft 19, since 181 direction of skewed slot of vortex groove 18 sees that Fig. 4 and vortex tube pipe shaft 19 are tangent, so injecting gas
Direction is also tangentially, vortex thus to be formed in vortex tube pipe shaft, and free vortex flow angular velocity of rotation is bigger closer to center, by
In angular speed difference, friction is generated in the layer and interlayer of free vortex flow, central part air-flow angular speed is maximum, and the result of friction is just
It is by the energy transmission of internal layer gas to outer layer, central core air-flow loses energy, and kinetic energy is low, and speed is low, by being vortexed groove center
Hole 182 enters left side cooling airway.And outer gas flow obtains energy, kinetic energy increases, while rubbing with the tube wall of vortex tube pipe shaft 19
It wipes, part kinetic energy is converted into thermal energy, flowed out from the right end of vortex tube by pressure regulator valve.The effect of pressure regulator valve is exactly to adjust two strands
The flow and temperature of hot and cold air.
Examples detailed above is only a specific embodiment of the utility model, also equal to its simple transformation, replacement etc.
In the protection scope of utility model.
