The cooler and terminal box being arranged on out frame, described two pedestal bearings are arranged on base and are located at stator respectively
The two ends outside of seat, described two pedestal bearings do not contact the end cap at place end, and the two ends of the rotor are each passed through stator
The end cap of support two ends setting is simultaneously supported on two pedestal bearings, and the hanger for lifting by crane is additionally provided with the base.
Further corresponding screwed hole, the pedestal bearing and base are provided with the pedestal bearing and base
By the bolt connection matched with the screwed hole, insulation spacer is lined between the pedestal bearing and base.
Further described two pedestal bearings are respectively 70 ~ 100mm with the distance of place end end cap.
Further the end cap is symmetrically point half formula end cap, and thickness is 10mm.
Further sealing ring is provided between the end cap and rotor.
The utility model is by the way that by rotor supports, on two pedestal bearings, pedestal bearing and rotor weight whole load-bearing exist
On base, end cap is not re-used as support member, and out frame is also not subjected to the weight of rotor and bearing, the end cap of motor and fixed
Handset seat can be made by more frivolous steel, save raw material, reduce manufacturing cost, and out frame be subjected only to it is electronic
The effect of electromechanical magnetic force, base also increases lifting surface area, when rotor rotates at a high speed, reduces the vibration of motor；By inciting somebody to action
Pedestal bearing do not contact where end end cap, the inner chamber isolation of pedestal bearing and out frame, it is to avoid inside because of out frame
Fan at a high speed the formed negative pressure of rotation and cause the generation of bearing Leakage.
Further on the pedestal bearing and it is provided with corresponding screwed hole, the pedestal bearing and bottom on base
Seat is lined with insulation spacer by the bolt connection matched with the screwed hole between the pedestal bearing and base, it is to avoid turn
Son forms the path of electric current with base, burns out motor.
Sealing ring is provided between further described end cap and rotor, it is to avoid dust enters inside out frame.
Brief description of the drawings
Fig. 1 is structural representation of the present utility model.
Specific embodiment
As shown in figure 1, the utility model includes base 3, sets motor body on the base 3 and be separately positioned on electricity
Two pedestal bearings 1 at owner's body two ends, the motor body includes rotor 5, out frame 4, is arranged in out frame 4
Stator winding 7 and stator core 6, the end cap 2 for being arranged on the two ends of out frame 4 and the cooler being arranged on out frame 4
10 and terminal box 8, the end cap 2 is symmetrically point half formula end cap, and thickness is 10mm, is easy to dismounting, and operation is provided with end cap 2
Hole, is easy to motor overall dynamic-balance；Sealing ring is provided between end cap 2 and rotor 5, it is to avoid dust enters inside out frame 4.
Described base 3 is welded by upper and lower two-layered steel plates and the supporting steel plate being arranged between two-layered steel plates, steel plate
Thickness welds the flatness of the upper and lower two-layered steel plates of post-processing between 10mm ~ 20mm, and flatness is controlled between 0.1 ~ 0.3mm；
The hanger 9 for lifting by crane is provided with base 3, hanger 9 and base 3 are welded as a whole, rigidity is good, lifted by crane and convenient transportation.
The screwed hole for installing pedestal bearing 1 and out frame 4, the stator are offered on the upper surface of the base 3
The screwed hole corresponding with the screwed hole opened up on base 3, out frame 4 and two are also provided with support 4 and two pedestal bearings 1
Individual pedestal bearing 1 is bolted on base 3 by with what the screwed hole matched, and between pedestal bearing 1 and base 3
It is lined with insulation spacer, it is to avoid rotor 5 forms the path of electric current with base 3, burns out motor；Described two pedestal bearings 1 distinguish position
In the two ends outside of out frame 4, and end where two pedestal bearings 1 are not contacted end cap 2, the two ends point of the rotor 5
Not Chuan Guo the two ends of out frame 4 set end cap 2 and be supported on two pedestal bearings 1, preferably two pedestal bearings 1 are distinguished
It is 70 ~ 100mm, negative pressure and pedestal bearing when can internal fan be rotated inside out frame 4 with the distance of place end end cap 2
1 is completely isolated, and after running for many years, zero oil leak is very clean inside out frame 4, reduces on-site maintenance work for motor
The risk of work amount and burn-down of electric motor.
Dowel hole is previously provided with described pedestal bearing 1 and also on out frame 4, after the completion of overall test,
It is using alignment pin 11 that pedestal bearing 1 and out frame 4 is urgent on the base 3 on the base 3 with drilling is twisted, in electronic captain
When time is run, it is ensured that out frame 4 and pedestal bearing 1 are not produced and axially and radially loosened, motor longtime running is improved
Reliability, the top of base 3 is also welded with the radial direction adjustment link stopper of adjustment out frame 4, is conveniently adjusted motor air gap.
In sum, the present apparatus is supported on two pedestal bearings 1 by by rotor 5, and one side end cap 2 is not re-used as branch
Support part part, the thickness of end cap 2 can be thinned to 10mm by conventional 60mm；On the other hand, because of pedestal bearing 1 and the weight of rotor 5
On the base 3, it is necessary to the rigidity of out frame 4 mitigates significantly, the thickness of out frame 4 can be subtracted by conventional 45mm for whole load-bearing
It is small to 20mm, the weight of out frame 4 mitigates significantly, has saved raw material；Again, because the weight of rotor 5 is born in A seating
On bearing 1, out frame 4 is subjected only to the effect of motor electromagnetic force, is not subjected to the weight of bearing and rotor 5, and base 3 increases
Big lifting surface area, so that the complete machine oscillation value of motor is reduced to 1.8mm/s by conventional 2.3mm/s, enhances motor
The stability of longtime running；The pedestal bearing 1 of last this transposition is isolated away from end cap 2, and the inner chamber of out frame 4, it is to avoid
Cause the generation of bearing Leakage because of the fan inside out frame 4 at a high speed the formed negative pressure of rotation, reduce motor
Maintenance cost, improve the reliability of motor.
Finally it should be noted that：Above example is only used to illustrate the technical solution of the utility model, rather than its limitations；
Although being described in detail to the utility model with reference to foregoing embodiments, one of ordinary skill in the art should manage
Solution：It can still modify to the technical scheme described in previous embodiment, or to which part or whole technologies
Feature carries out equivalent；And these modifications or replacement, the essence of appropriate technical solution is departed from the utility model reality
Apply the scope of a technical scheme.
