Abstract
The invention relates to an online magnetic variation force vibration exciter. The online magnetic variation force vibration exciter uses electromagnetism separation and reunion functions. A moving eccentric block and a fixing eccentric block are installed on a shaft of the online magnetic variation force vibration exciter. When the shaft of the online magnetic variation force vibration exciter rotates, the fixing eccentric block rotates along with the shaft, and during the rotation process of the fixing eccentric block and the shaft, eccentric force is generated in single chip mode, and transmitted exciting force is relatively small. If the exciting force needs to be increased in motion, an existing vibration motor can not achieve the purpose of increasing the exciting force, and the exciting force can be increased only by increasing overlap rate of the eccentric blocks. According to the online magnetic variation force vibration exciter, an electromagnetic mechanism installed on the fixing eccentric block is powered on in online mode under the circumstance that a motor rotates at high speed, the fixing eccentric block and the moving eccentric block are instantaneously attracted together through powerful magnetic force generated by the electromagnetic mechanism, eccentric mass is increased, and therefore the eccentric force is increased. If the exciting force needs to be decreased, the electromagnetic mechanism is powered off, the magnetic force disappears, the fixing eccentric block and the moving eccentric block are rapidly separated from each other, and therefore the eccentric force is decreased. The online magnetic variation force vibration exciter is mainly used in all industries of coal, metallurgical mines and the like, and provides the online magnetic variation exciting force to various vibrating machines of a vibrating feeder, a vibrating screen and the like.
Description
Technical field
The present invention relates to a kind of online magnetic variation power vibrator, be mainly used in the every profession and trades such as coal, metallurgical mine, chemical industry, building materials, casting, oil, grain, for all kinds of vibrating machines such as oscillating feeder, vibration ore dumping machine, vibratory sieve, vibration blanker provide the vibrator of online magnetic variation exciting force.
Background technology
At present, exciting source in vibrating feed (screening) equipment that the industry such as coal in China, metallurgical mine uses, one is vibrating motor (electric activator or vibration source three-phase abynchronous motor), and another kind is the vibrator with eccentric stiffener driven by common electric machine.The vibrator vibration force of these two kinds of forms all can not in equipment running process its size of on-line tuning; all must under stopped status; the size of the adjustment coincidence angle of vibrating motor eccentric block or the eccentric block quality of eccentric stiffener vibrator, changes the size of exciting force.Now, in the vibratory equipment of coal in China, metallurgical mine, a kind of size that can change exciting force in running easily of special needs, thus the vibrator of on-line tuning production capacity size.
Summary of the invention
For adapting to mine needs, overcoming the shortcoming of current various vibrator, the object of this invention is to provide a kind of size that can change exciting force in equipment running process easily, thus the online magnetic variation power vibrator of adjustment production capacity.
For achieving the above object, the technical solution adopted for the present invention to solve the technical problems is: a kind of online magnetic variation power vibrator, is made up of bearing group, power transmission shaft, eccentric block, electromagnetic mechanism, housing, shaft coupling and motor.The two ends of power transmission shaft are respectively arranged with bearing group in order to supporting shaft, the bearing group at two ends is connected with the sidewall of housing by bolt, the fixed eccentric block that the centre of power transmission shaft is provided with movable eccentric block and is connected by key with power transmission shaft, fixed eccentric block is provided with electromagnetic mechanism, communicated with the collecting ring be arranged on power transmission shaft by wire, the brush on collecting ring is connected with the binding post of housing.
The online magnetic variation power vibrator of said structure, its movable eccentric block freely can rotate on power transmission shaft, fixed eccentric block then rotates together with power transmission shaft, leaves certain interval between movable eccentric block and fixed eccentric block, keeps this gap by the spring of electromagnetic mechanism.When drive axis, movable eccentric block does not also rotate together with power transmission shaft, after electromagnetic mechanism switches on power, the electromagnetic attraction produced and movable eccentric block attracting and, movable eccentric block is rotated together with fixed eccentric block, when after electromagnetic mechanism power-off, movable eccentric block and fixed eccentric block are thrown off.
The online magnetic variation power vibrator of said structure, one end of its power transmission shaft can be connected with power source motor by the shaft coupling that is flexible coupling, and also can be connected with power source motor by belt pulley.When vibrator is installed, the bed bolt hole by housing is connected with vibratory equipment, and motor is connected with basis.
The movable eccentric block of the online magnetic variation power vibrator of said structure, fixed eccentric block, electromagnetic mechanism, collecting ring and brush can be designed as be arranged on special two shaft threephase asynchronouses two end axles on, guard shield is connected with motor housing.
The present invention adopts said structure compared with prior art to have following features.
1, the present invention utilizes electromagnetic clutch effect, movable eccentric block and fixed eccentric block is set up on vibrator power transmission shaft or on the projecting shaft at motor two ends, when power transmission shaft or motor shaft rotate, fixed eccentric block rotates together with axle, eccentric force is now that monolithic produces, and the exciting force relatively spread out of is less.If need to increase exciting force at the volley, the vibrating motor of prior art is irrealizable, under stopped status, must increase the registration of eccentric block, strengthen exciting force.The technology of the present invention is exactly when motor is with fixed eccentric block High Rotation Speed, online connection is arranged on the electromagnetic mechanism on fixed eccentric block, its powerful magnetic force produced and the instantaneous adhesive of movable eccentric block, make the eccentric block at motor two ends increase eccentric mass, and strengthen exciting force.During as needs minimizing exciting force, electromagnetic mechanism power-off, magnetic force disappears, and utilize the spring on electromagnetic mechanism to make fixed eccentric block and movable eccentric block quick separating, exciting force diminishes.
2, the present invention is that one of vibrator design aspect is innovated greatly, has filled up the blank of domestic online magnetic variation power vibrator aspect.
