Abstract
Elevator motor, including motor, motor is provided with output shaft, worm screw it is provided with on output shaft, worm and wheel coordinates, and motor lower surface is provided with thrust bearing, is provided with current monitoring device in motor, the upper surface of motor is provided with ball bearing, the outer ring of ball bearing is fixedly installed elastic ring, and the outer ring of elastic ring is fixing with motor to be connected, and the both sides of elastic ring are provided with push rod, push rod is controlled by current monitoring device by air cylinder driven, cylinder.This utility model has the advantages that after using ball bearing instead, and ball can be finely adjusted joint, when worm and gear coordinates bad, current monitoring device starts cylinder, utilizes push rod to promote elastic ring, is finely adjusted the position of whole worm screw, reduce abrasion, extend electrical machinery life.
Description
Technical field
This utility model belongs to car up/down motor field, is specifically related to elevator motor.
Background technology
Glass-frame riser is the lowering or hoisting gear of a kind of door/window glass of automobile, and glass lifter motor is in glass-frame riser
Power source, glass lifter motor mainly includes the motor shaft with rotor, and motor shaft is fixed with worm screw, and worm and wormwheel coordinates
Using, complete the self-locking of glass, but motor shaft is in installation process in lifting process, upper and lower two ends use originally
Thrust bearing, when filling in motor shaft, it is easy to causes motor shaft to tilt to install, the worm and wheel on motor shaft after inclination
Interference fits or when not having fully mated, can serious wear, produce substantial amounts of chip, produce noise time serious, to motor
Turbine injury is 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 elevator motor, when solving the assembling of existing motor,
Worm and gear tilts to coordinate the problem causing abrasion.
This utility model is achieved through the following technical solutions.
Elevator motor, including motor, described motor is provided with output shaft, described output shaft is provided with snail
Bar, described worm and wheel coordinates, and described motor lower surface is provided with thrust bearing, is provided with electric current in described motor
Monitoring device, the upper surface of described motor is provided with ball bearing, and the outer ring of described ball bearing is fixedly installed flexible
Circle, the outer ring of described elastic ring and motor fix and 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.By current monitoring, judge that the position of output shaft is installed
Time either with or without inclination, utilize wireless technology simultaneously, control startup and the closedown of cylinder.
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.
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, reduces abrasion,
Extend 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.
Detailed description of the invention
Below in conjunction with the accompanying drawings with detailed description of the invention, this utility model is described further.
Elevator motor, including motor 7, described motor 7 is provided with output shaft 3, described output shaft 3 is provided with
Worm screw 1, described worm screw 1 coordinates with worm gear 2, and described motor 7 lower surface is provided with thrust bearing, sets in described motor 7
Being equipped with current monitoring device, the upper surface of described motor 7 is provided with ball bearing 5, and the outer ring of described ball bearing 5 is fixed
Being provided with 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 provided with and push away
Bar 6, described push rod 6 is controlled by current monitoring device by air cylinder driven, described cylinder, described current monitoring device bag
Include the control circuit being installed on motor 7 rotor coil, described control circuit be in series with a resistance, described push rod 6 with
By being welded and fixed between elastic ring 4.
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.
Protection domain of the present utility model includes but not limited to embodiment of above, and protection domain of the present utility model is with power
Profit claim is as the criterion, and replacement that any those skilled in the art making this technology is readily apparent that, deforms, improves and each fall within
Protection domain of the present utility model.
