18, above-mentioned outlet structure is applied to the outlet of explosion-proof motor, has safe and reliable to operation, installation and debugging convenience, saving pneumatics
Machine inner space, winding displacement facilitate advantage.
Table 1 is the fore bearing section 45 that present invention employs the electric machine main shaft 40 that insulating element fore bearing after 80s 25 is fixed
Radius run-out degree micron and the front axle of the electric machine main shaft 40 do not fixed using the fore bearing 2 of the constant power motor of insulating element 80
The experimental data holding section 45 radius run-out degree micron compares.
The data of the radius run-out degree micron at table 1 fore bearing section 45 position compares
Contrasting data from table 1 is it follows that to employ insulating element after 80s, suffered by fore bearing 25 for fore bearing 25 outer end
Mitigate abrasion to load to reduce, lead to the radius run-out degree at fore bearing section 45 position of electric machine main shaft 40 that fore bearing 25 fixed
Micron is more stable.
Table 2 is that outer bearing in the present invention props up to hold round 89 surfaces and employ the nickel that a layer thickness is 0.31 to 0.39 millimeter and closes
Golden hard wear-resistant layer and outer bearing prop up that to hold round the nickel alloy hard that 89 surfaces are not 0.31 to 0.39 millimeter using a layer thickness resistance to
The corrosion resistant wear test data of mill layer compares.
The outer bearing of table 2 insulating element 80 props up and holds round 89 surface abrasion data and compare
Contrasting data from table 2 is it follows that the outer bearing of insulating element 80 props up and holds round 89 surfaces and have a layer thickness to be
0.31 to 0.39 millimeter of nickel alloy hard wear-resistant layer, possesses superpower wearability.
Prop up positioned at component flange 87 outside outer bearing among insulating element 80 in the present invention and hold round 89 and component for adjusting ring
82 cylindrical between axiality be 100 millimeters of unit sizes error be less than or equal to 0.001 millimeter.In order to ensure insulating element
Outer bearing on 80 prop up hold round 89 and component for adjusting ring 82 cylindrical between there is high accuracy axiality.
Said structure achieves electric machine main shaft 40 and fore bearing 25 and rear bearing 35 is only subjected to pure torsion, and flat belt
It is but to be born by no inner-ring bearing 60 completely that produced radial load reacts to flat-belt pulley 90, be only operated at every
On component 80, the main shaft on completely isolated electric machine main shaft 40 bears radial load for overhanging section 46；Due to meeting in rated power
On the premise of, the diameter seeking electric machine main shaft 40 can be accomplished that the limit is little in design, be solely subjected to pure torsion, simultaneously as every
Belong to hollow short tube from component 80 global shape, therefore structural rigidity is superpower, can bear bigger radial load.Both combine, this
Invention achieves and can be made compact motor overall dimensions, can bear bigger radial load again, runs relatively reliable, thus prolonging
Grow the service life of motor.
