Description
Technical field
This utility model relates to main shaft device, relates more specifically to can be preferably used in rotating spraying type electrostatic application
Main shaft device in putting.
Background technology
In the past, in the case of the vehicle body of spray car, appliances etc., use transfer efficiency of coatings and the spray process of coating
Good rotating spraying formula electrostatic spraying apparatus sprays.Main shaft dress in this rotating spraying type electrostatic spraying apparatus
Putting and have air motor, this air motor has: motor shell, and it is formed with the axis hole axially extended, and at this axis hole
Base end side be formed with turbine room;Rotary shaft, it is located in the axis hole of this motor shell, and tip side is dashed forward from this motor shell
Go out;And turbine, it is located at the base end side of this rotary shaft and is accommodated in turbine room.It addition, the top of the rotary shaft at air motor
End is provided with the rotating spraying nozzle of referred to as cup.And, rotating spraying type electrostatic spraying apparatus is by turbine supply height
Pressure air, and make cup such as carry out high speed rotating with the rotation speed of 3000~150000rpm.When limit to spray equipment be sprayed-on
Pay potential difference between thing, while to this rotation status cup supply coating time, coating under by micronized state from clock
Shape cup discharges.Thus, rotating spraying type electrostatic spraying apparatus can be by micronized coating particle towards being sprayed-on thing spraying.Separately
Outward, the axial rearward end at turbine has the rotation detection device (such as patent documentation 1) of the rotation detecting turbine.This rotation detects
Device is the rotation detection device of optical profile type, as it is shown on figure 3, make the one of the end of the circular flange part of axial turbine rear end
Part incised notch, and the region and non-reflective region making incident illumination reflect according to the rotating position phase of turbine is set, thus carry out
The detection of position of rotation.

Patent documentation 1: Japanese Unexamined Patent Publication 2010-284637 Japanese Laid Open Patent
Utility model content
But, in the main shaft device for conventional rotating spraying type electrostatic spraying apparatus, need be used in rotation
On the flange part of the turbine of detection, incised notch shape is set, becomes the miscellaneous main cause with cost increase of flow chart.It addition, by
In making rotary shaft drive to turbine jet-stream wind, so the moisture in air can be attached on turbine to become get rusty main
Reason.
In order to solve above-mentioned problem, this utility model provides a kind of main shaft device, by multiple turbo blades are sprayed gas
Body and make rotary shaft rotate and drive, it has: above-mentioned rotary shaft, this rotary shaft has the axle of hollow form, has discoid circle
Card and be integrally provided at above-mentioned axle one end flange part and with the circle-shaped multiple above-mentioned turbine being located on above-mentioned flange part
Blade;Housing, it receives this rotary shaft;And gas bearing, its install on the housing and by the supply of gas relative to
Above-mentioned housing is in a non-contact manner by above-mentioned rotary shaft floating support, and above-mentioned main shaft device is characterised by, at above-mentioned turbine
It is formed with black conversion coating in a part for the overall and above-mentioned disc face of blade.
The effect of utility model
According to the main shaft device being used in rotating spraying type electrostatic spraying apparatus of the present utility model, it is not necessary to complicated processing
Just can carry out the rotation detection of rotary shaft, it is also possible to prevent getting rusty of turbo blade.
Accompanying drawing explanation
Fig. 1 is the sectional view representing main shaft device of the present utility model.
Fig. 2 be the A representing Fig. 1 to regarding under the figure of rotary shaft.
Fig. 3 is the axonometric chart representing conventional turbine wheel.
Detailed description of the invention
As shown in Figure 1 and Figure 2, the main shaft device 10 for rotating spraying type electrostatic spraying apparatus of present embodiment has
Rotary shaft 1, this rotary shaft 1 has the axle 1a of hollow form, has discoid disc face and be integrally provided at one end of above-mentioned axle
Flange part 1c and with the circle-shaped multiple turbo blade 1d being located on above-mentioned flange part.It addition, above-mentioned rotary shaft 1 is accommodated in
In housing 2, and there is in above-mentioned housing 2 supply by gas and in a non-contact manner will relative to above-mentioned housing 2
The gas bearing 3 of above-mentioned rotary shaft 1 floating support.Whole of above-mentioned multiple turbo blades is formed with black conversion coating
1b, is sprayed to above-mentioned turbo blade by gas and makes above-mentioned rotary shaft rotate and drive, and prevent based on being contained in gas
Getting rusty of the turbo blade that moisture is caused.It addition, in above-mentioned disc face, along the circumferencial direction of disc face in a part
It is also formed with black conversion coating.Owing to the disc face of this flange part to be set to the reading face of optical pickocff, so by black
The region that conversion coating is formed can calculate the position of rotation of above-mentioned rotary shaft as non-detection position.
According to the main shaft device being used in rotating spraying type electrostatic spraying apparatus of the present utility model, it is not necessary to complicated processing
Just can carry out the rotation detection of rotary shaft, it is also possible to prevent getting rusty of turbo blade.
