Worm gear uses, and completes the self-locking of glass, but motor shaft is in installation process in lifting process, and upper and lower two ends are originally
Use thrust bearing, when filling in motor shaft, it is easy to cause motor shaft to tilt to install, the snail on motor shaft after inclination
Worm and wheel interference fits or when not having fully mated, can serious wear, produce substantial amounts of chip, time serious, produce noise,
The turbine of motor is injured big especially, so makes be greatly shortened the service life of motor.
Summary of the invention
For deficiency of the prior art, this utility model provides a kind of elevator motor, solves existing group of motors
During dress, worm and gear tilts to coordinate the problem causing abrasion.
This utility model is achieved through the following technical solutions.
A kind of elevator motor, including motor, described motor is provided with output shaft, described output shaft is provided with
Worm screw, described worm and wheel coordinates, and described motor lower surface is provided with thrust bearing, is provided with electricity in described motor
Stream monitoring device, the upper surface of described motor is provided with ball bearing, and the outer ring of described ball bearing is fixedly installed bullet
Property circle, the outer ring of described elastic ring and motor are fixing to be connected, and the both sides of described elastic ring are provided with push rod, described push rod
By air cylinder driven, described cylinder is controlled by current monitoring device, and the upper surface of described motor is provided with air-out apparatus, institute
The bottom of the air-out apparatus stated is provided with electric magnet, at described air-out apparatus alignment worm and wheel cooperation.Supervised by electric current
Control, judges when the position of output shaft is installed either with or without inclination, utilizes wireless technology simultaneously, controls startup and the pass of cylinder
Close, utilize blowing device, the chip originally sticked on worm gear is blown off.
As preferably, described current monitoring device includes the control circuit being installed on motor-spin-coil, described
A resistance it is in series with in control circuit.Owing to resistance is relatively big, when electric current changes, according to Ampere theorem, the change of voltage
Change big.
As preferably, by being welded and fixed between described push rod and elastic ring.Fixation, intensity is big.
As preferably, described electric magnet is by current monitoring device control.The power on/off of electric magnet is also by current monitoring
Device controls, only when wearing and tearing bigger, and just meeting attracting debris, using electricity wisely.
Compared with prior art: after using ball bearing instead, ball can be finely adjusted joint, when worm and gear coordinates bad
Time, current monitoring device starts cylinder, utilizes push rod to promote elastic ring, is finely adjusted the position of whole worm screw, blowing device
Blow off chip, electricity consumption magnet adsorption, reduces abrasion, extends electrical machinery life.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model.
Fig. 2 is ball bearing of the present utility model and the top view of output shaft cooperation.
Fig. 3 is the enlarged drawing in this utility model at Figure 1A.
Detailed description of the invention
Below in conjunction with the accompanying drawings with detailed description of the invention, this utility model is described further.
A kind of elevator motor, including motor 7, described motor 7 is provided with output shaft 3, described output shaft 3 sets
Being equipped with worm screw 1, described worm screw 1 coordinates with worm gear 2, and described motor 7 lower surface is provided with thrust bearing, described motor 7
Inside being provided with current monitoring device, the upper surface of described motor 7 is provided with ball bearing 5, the outer ring of described ball bearing 5
Being fixedly installed elastic ring 4, the outer ring of described elastic ring 4 is fixing with motor 7 to be connected, and the both sides of described elastic ring 4 are arranged
Push rod 6, described push rod 6 is had to be controlled by current monitoring device by air cylinder driven, described cylinder, described motor 7 upper
End face is provided with air-out apparatus 9, and the bottom of described air-out apparatus 9 is provided with electric magnet 8, and described air-out apparatus 9 is directed at snail
Bar 1 coordinates place, described current monitoring device to include the control circuit being installed on motor 7 rotor coil with worm gear 2, described
Being in series with a resistance in control circuit, by being welded and fixed between described push rod 6 and elastic ring 4, described electric magnet 8 is by electricity
Stream monitoring device controls.
In use, when worm screw 1 and worm gear 2 interference fits or when coordinating inadequate, the abrasion between worm gear 2 and worm screw 1
Increasing, the current monitoring device in motor 7 is monitored in real time, after the electrical current of coil increases, and the resistance of series connection in control circuit
The voltage instantaneous at two ends increases, and transmits wireless signals to cylinder, due to do not know worm screw 1 and worm gear 2 interference fits or
Cooperation causes not.
First driving left cylinder to start, push rod 5 promotes elastic ring 4, carries out the most micro-skew, drives ball bearing 5 and defeated
The most micro-skew of shaft 3, so that worm screw 1 separates slightly with worm gear 2, if now the voltage of resistance two ends feedback is just recovering
Often, then quit work.
If the voltage of resistance two ends feedback continues to increase, then closing left cylinder, start right cylinder, push rod 5 promotes elasticity
Circle 4, offsets to the right, drives ball bearing and output shaft 3 to offset to the right, so that worm screw 1 is the most close with worm gear.
The upper surface of motor 7 is provided with air-out apparatus 9, start by set date air-out apparatus 9, and air-out apparatus 9 is towards worm screw 1 and snail
Take turns and blow at 2 cooperations, cause being further worn out preventing the chip worn and torn from continuing to stick on worm gear 2, the chip simultaneously blown off, will
Can be adsorbed by electric magnet 8.
The energising of electric magnet 8 and power-off control with current monitoring device, when current monitoring device has signal to launch
Time, electric magnet 8 is energized.
