Technical field
The present invention relates to a kind of elevator hoist.
Background technology
Existing permanent magnetic synchronous traction machine has enough traction power when the low speed in order to guarantee, need to adopt a large amount of permanent magnets, because the synchronous anodontia towing machine of rare earth permanent magnet has compact conformation, the efficient height, energy-saving effect is remarkable, need not the outstanding joint advantage of gear lubrication wet goods, therefore, the synchronous anodontia towing machine of rare earth permanent magnet has become the first-selected product of elevator, but, increase along with the rare-earth permanent magnet demand, and national regulation and control to the rare earth policy, cause the rare earth permanent-magnetic material price to rise steadily, for example: rare-earth permanent magnet needs De Praseodymium Nd alloy, from the year before 300000 yuan/ton increase to present 1,700,000/ton, to such an extent as to permanent-magnet synchnorous gearless dragging machine cost straight line rises, in addition, motor is when low cruise, its efficient generally has only more than 80%, is difficult to the efficient that reaches satisfied.And the towing machine of asynchronous interchange worm gear, worm reduction gear unit structure because the rotating speed of motor height, needs the mechanical reduction gear of bigger converter speed ratio, and this mechanical reduction gear energy consumption height, noise are big, and power factor is low.
Summary of the invention
Goal of the invention of the present invention is to provide a kind of can effectively reduce the permanent magnetic synchronous traction machine permanent magnet consumption, that efficient is high, band speed reduction gearing that noise is little, that power factor is high.
The present invention realizes like this, comprise permasyn morot, gear reducer, permasyn morot shaft extension end cooperates with the gear reducer input end, permasyn morot front end cover end face is processed with seam, cooperate with the seam of gear reducer input end, and permasyn morot and gear reducer are coupled together with bolt, permasyn morot inside is provided with brake wheel, brake wheel is installed in the rear end of the rotating shaft of permasyn morot, the both sides of permasyn morot are equipped with block brake, block brake is fixed by bolts on the support of permasyn morot, the inboard brake shoe of block brake is pressed on the brake wheel cylindrical after passing the support square hole, the processing of permasyn morot rear side housing is porose, the miniature gears of jigger wheel front end passes hole and the jiggering gear mesh that is installed in the permasyn morot, and traction sheave is connected on the gear reducer output shaft.
For reducing axial dimension, brake wheel is made bowl shaped structure, and the permasyn morot stator winding stretches in the bowl-type brake wheel, and the bowl-type brake wheel surrounds stator winding.
In order to increase radiating effect, at the p-m rotor two ends of permasyn morot, be provided with the centrifugal fan blade of radial arrangement, during rotor rotation, the centrifugal fan blade can dispel the heat to winding.
For the heat that makes motor internal comes out, be provided with ventilating heat dissipating hole in left end, right-hand member, the lower end of permasyn morot.
The jiggering gear is installed on the brake wheel end face seam, and is simple and reliable.
Principle of work
During work, band-type brake is opened in the drg energising, and the p-m rotor high speed revolution by making traction sheave be in low speed rotation after the reducer gear deceleration, like this, has just satisfied the requirement of towing machine needs slow runnings.
If when needing the jiggering rescue, the miniature gears of jigger wheel front end can be passed ending cover hole and the jiggering gear mesh that is installed in the motor; The rotating disc wheel, by miniature gears band big gear wheel, add reducer gear by at a high speed to the low speed ratio effect, jigger wheel is easy to rotate, and implements to rescue.
Reducer output shaft can the direct mount traction sheave, also can be connected by the traction wheel shaft of coupler with two ends tape spool bearing.
Beneficial effect
1 permasyn morot can be realized high-speed cruising by speed reduction gearing, can reduce motor volume, reduces the permanent magnet consumption, cost-cutting.
2 permasyn morot high-speed cruising, efficient can reach 95%, and gear reducer efficient also can reach 98%, and total electromechanical efficiency can reach 93%, and is also higher 10 percentage points than existing permanent magnetism synchronization gear wheel free structure towing machine efficient.
3 adopt permasyn morot as power, need not to draw reactive component of current from electrical network, thereby the power factor height;
4 adopt block brake, and simple in structure, volume is little.
5 two ends of rotor band centrifugal fans, to the stator good cooling results, temperature rise is low, the functional reliability height.
6 supports have breather port, and the motor internal hot air can be discharged smoothly, good heat dissipation effect.
