Abstract
The utility model discloses an electric vibration exciter which is suitable for various vibrating apparatus in mine industry, metallurgy industry, coal industry, chemical engineering industry, building material industry, etc. The electric vibration exciter comprises a vibrator, a casing, bearings and motors. The utility model is characterized in that the outboard shaft ends of the two bearings of the vibrator are respectively provided with the same motors through cantilevers; two motor rotors are coaxial with the vibrator; the two motor rotors are respectively fixed in motor casings; the two motor casings are connected with a vibrator casing by flanges; the two motors shares one power leading wire. The utility model adopts power division, as a result, the heat source is dispersed, and the average temperature rise is below 25 DEG C. The utility model has simple structure, small volume, light weight, long service life and low cost.
Description
The utility model relates to the common mechanical vibration, and the electric activator that particularly a kind of power source and exciting source are integrated is applicable to all kinds of vibratory equipments of industry such as mine, metallurgy, coal, chemical industry, building materials.
Existing exciting source has electromagnetic vibrator, vibrating motor and mechanical vibration exciter etc., and the electromagnetic vibrator noise is big, weight big, the dust influence is big; Vibrating motor is shorter useful life; Mechanical vibration exciter needs adapted power source and transmission device, and volume is big, complex structure, and power demand is big.
The purpose of this utility model is the electric activator that design a kind of power and vibration two sources simple in structure, that volume is little, the life-span is long, function is strong are integrated.
Task of the present utility model is finished as follows, this electric activator includes oscillator, housing, bearing and motor, it is characterized in that: oscillator two bearings outside axle head respectively cantilever identical motor is arranged, two rotors are coaxial with oscillator, two motor stators are separately fixed in the motor casing, be connected with flange between two motor casings and the oscillator housing, two motors are totally one power outlet.
The utlity model has following effect; Be connected in one because of there are two identical motor coaxles at oscillator axle two ends, guarantee that vibration source two ends amplitude equivalence, the vibration shape are identical, have saved transmission device, reduced the bearing consumption, weight and volume is reduced, power sets up separately simultaneously, thermal source disperses, and average temperature rising is lower than 25 degree, long service life.Directly be loaded on vibratory equipment, saved and passed the parts that shake, designs simplification, cost is low.
Fig. 1 is the structural representation of the utility model electric activator.
Describe embodiment in detail in conjunction with above accompanying drawing.
The utility model electric activator includes an off-centred dipole 6 and housing 5 and two cover block bearings 3, two bearings 3 outside axle heads of oscillator 6 respectively cantilever identical motor is installed, rotor 9 and oscillator 6 are coaxial or connect with shaft coupling, there is flange at housing 5 two ends of oscillator 6, two motor stators 2 are separately fixed at 7 li of motor casings, the two ends of motor casing 7 are provided with flange, the outer end is used for assembling with vibratory equipment, inner flange with oscillator housing 5 passes through Bolt Connection, and two motors are totally one power outlet 1.Motor casing 7 is provided with towards the oil filler point 8 of each bearing 3 and outage 4, the friction temperature when being used for reducing work.During work, this electric activator directly is contained on the vibratory equipment by its shell two end flanges, energized, two motors are by the electromagnetic induction of stator and rotor, produce rotating magnetic field and promote the rotation of two rotors, drive oscillator 6 rotations, produce entad circular vibration power, make vibratory equipment do the vibration of circle track.According to the purposes needs, also can be loaded on and do straight-line oscillation on the vibratory equipment with the two electric activators of the electric activator disjunctor of two direction of rotation composition arranged side by side.
