Description of drawings
Fig. 1 permanent-magnet synchnorous gearless dragging machine front view;
Fig. 2 permanent-magnet synchnorous gearless dragging machine constructional drawing.
The specific embodiment
Indicate among the figure: [1] support, [2] drg, [3] retaining rope bar, [4] connection box, [5] jiggering signalling apparatus, [6] coder, [7] stator, [8] rotor, [9] jiggering transmission gear, [10] traction sheave and axle, [11] main bearing, [12] location bearing.
Rare earth permanent magnet synchronization gear wheel free motor according to Fig. 1,2 provides because main frame rotating shaft and rotor traction sheave are integral molding, thereby has guaranteed the structural strength of rotating element and the concentricity of main frame operation effectively.Complete machine is by the location bearing carrying of the main bearing [11] and the other end.The traction wheel shaft can bear top load and high-fatigue strength.
Photoelectric encoder [6] is installed in the back of motor center rotating shaft, and it is connected to frequency converter by a plug type joint.Electric and the temperature monitoring equipment of motor is connected by connection box [4].
As seen from Figure 1, native system is equipped with two and overlaps independently brake component [2], the reset force of contained spring is realized declutching and the band-type brake action when electromagnetic force during drg utilization energising and outage, and the part overall package is an independently electric component in the drg, is convenient to assembling and dismounting and change.If needed, the hexagonal swivel release gear that can utilize the spanner that declutches of configuration to pull the drg end discharges drg.
When elevator is in urgent stop situation, open that the U-shaped cover plate exposes the circular hole in the main frame upper right corner, the switch motion feedback signal in the jiggering signalling apparatus [5].Use handwheel front end miniature gears, allow pinion shaft insert in the aperture of main frame upper right side, miniature gears is cooperated with jiggering transmission gear [9], rotate handwheel drive traction sheave and rotating shaft [8] rotation, with this moving elevator to correct position.
When normal operation, frequency converter is powered to armature loop, and the main magnetic field mutual action that this armature field and outer rotor magnet steel produce produces electromagnetic torque, drives the towing machine rotation, makes the car up-and-down movement of elevator by the steel rope on the traction sheave.
When starting, drg [2] energising, its suction overcomes the spring pressure of brake inside, and brake strip and outer rotor are disengaged.After the stator energising, electrical motor brings into operation; When electrical motor stopped, drg [2] outage leaned on the pressure of brake inside spring to produce lock torque between friction lining and outer rotor, makes elevator stopping.
In sum, the utility model provides a kind of design science reasonable, can extensively satisfy and use the towing machine that machine room or machine-roomless lift are arranged in villa and the low-rise dwelling, and it has scientific arrangement, compact conformation, volume is little, load-carrying is reasonable, saved energy consumption effectively, and safe in operation.
