Description
Technical field
The present invention relates to a kind of online magnetic variation power vibrator, it is mainly used in the every profession and trades such as coal, metallurgical mine, chemical industry, building materials, casting, oil, grain, the vibrator of online magnetic variation exciting force is provided for all kinds of vibrating machines such as oscillating feeder, vibration ore dumping machine, vibratory sieve, vibration blankers.
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 both forms all can not in equipment running process its size of on-line tuning; all must be under stopped status; adjust the coincidence angle of vibrating motor eccentric block or the size of the eccentric block quality of eccentric stiffener vibrator, change the size of exciting force.Now, in the vibratory equipment of coal in China, metallurgical mine, it is accordingly required in particular to a kind of size that can change exciting force in running easily, thus the vibrator of on-line tuning production capacity size.
Summary of the invention
For adapting to mine needs, the shortcoming overcoming current various vibrator, it is an object of the invention to provide a kind of size that can change exciting force in equipment running process easily, thus adjust the online magnetic variation power vibrator of 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 support power transmission shaft, the bearing group at two ends is connected with the sidewall of housing by bolt, the centre of power transmission shaft is provided with movable eccentric block and the fixed eccentric block being connected with power transmission shaft by key, electromagnetic mechanism is installed on fixed eccentric block, being communicated with the collecting ring being 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 can be freely rotatable on power transmission shaft, fixed eccentric block then rotates together with power transmission shaft, leaves certain interval, keep this gap by the spring of electromagnetic mechanism between movable eccentric block and fixed eccentric block.When drive axis, movable eccentric block does not also rotate together with power transmission shaft, after electromagnetic mechanism switches on power, produced electromagnetic attraction attracting with movable eccentric block and, movable eccentric block is made to rotate together with fixed eccentric block, when, after electromagnetic mechanism power-off, movable eccentric block disengages with fixed eccentric block.
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, it is also possible to is connected with power source motor by belt pulley.When vibrator is installed, can be connected with vibratory equipment by the bed bolt hole of housing, motor is connected with basis.
Movable eccentric block, fixed eccentric block, electromagnetic mechanism, collecting ring and the brush of the online magnetic variation power vibrator of said structure can be designed as being arranged in the two end axles of special double shaft threephase asynchronouses, and guard shield is connected with motor housing.
The present invention uses said structure compared with prior art to have following features.
1, the present invention is to utilize 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 now is that monolithic produces, and the exciting force relatively spread out of is less.If needing to increase at the volley exciting force, the vibrating motor of prior art is irrealizable, it is necessary under stopped status, increases the registration of eccentric block, strengthens exciting force.The technology of the present invention is exactly in the case of motor is with fixed eccentric block High Rotation Speed, connect the electromagnetic mechanism being arranged on fixed eccentric block online, its powerful magnetic force produced and the movable instantaneous adhesive of eccentric block, make the eccentric block at motor two ends increase eccentric mass, and strengthen exciting force.If desired for when reducing exciting force, electromagnetic mechanism power-off, magnetic force disappears, and utilizes the spring on electromagnetic mechanism to make fixed eccentric block and movable eccentric block quick separating, and exciting force diminishes.
2, the present invention is that the one of vibrator design aspect is innovated greatly, has filled up the blank in terms of domestic online magnetic variation power vibrator.
