Abstract
The invention relates to an elliptic vibration machine with parallel shafts and double excitation motor. The elliptic vibration machine mainly consists of a feed hopper, a vibration body, excitation motors, a swing motor base, swing motor base vibration damping springs, a vibration body support spring, a base, and the like. One excitation motor is directly arranged on the vibration body, and the other excitation motor is arranged on the swing motor base connected the vibration body, through a hinge; under the action of a group of vibration damping springs between the swing motor base and the vibration body, the swing motor base and the excitation motors swing together in a certain angle range through the excitation force generated by the excitation motors on the swing motor base, the generated centrifugal inertia force and the excitation force of the excitation motors are combined to ensure that the vibration body does an approximately linear motion, the vibration body does a circular motion through the excitation motors directly arranged on the vibration body, and the two motions are combined to form an elliptic motion of the vibration body. The elliptic vibration machine with the parallel shafts and the double excitation motors has high strength of the vibration body, even force output of the two motors and capability of realizing the needed elliptic motion.
Description
Technical field
The present invention relates to the two shock electric machine elliptical vibration machines of a kind of parallel axes that industries such as oil, coal, metallurgy, chemical industry, building are used.
Background technology
At present, the two shock electric machines of employing both domestic and external realize that the elliptical vibration machine has following several:
The elliptically vibrating screen of U.S. Pat 5265730 has adopted two identical short shock electric machines, be installed in symmetrically on the biside plate of screen box, two electrical axis are " eight " font, the inertial excitation force vector that motor produces period of motion is projected as ellipse in the screen box plane of movement, produced a component on perpendicular to the sieve box side plate direction, two motor symmetric arrangement are cancelled out each other this component.In the time will realizing the balanced elliptic motion of screen box, the line of the axis mid point of two motors will pass through the screen box barycenter, make the design of vibratory sieve be subjected to the certain condition restriction like this, when actual design, possibly can't satisfy, in addition, because this installation form of motor, on direction, be subjected to the bigger load of the screen box oscillating movement not being had contribution during work perpendicular to sieve box side plate, cause sieve box side plate to bear biaxial stress, the intensity of screen box reduces greatly.
Chinese patent ZL02235186.8 elliptically vibrating screen has also adopted axis to be two identical short shock electric machines of " eight " font, be installed in symmetrically on the crossbeam across screen box, different with US5265730 is, the eccentric block at the shock electric machine axle two ends of US5265730 is same direction, the eccentric block at each shock electric machine axle two ends of ZL02235186.8 is certain included angle, the line of the axis mid point of such two motors does not need by the screen box barycenter, also can realize the balanced elliptic motion of screen box, but, after the eccentric block at shock electric machine axle two ends is certain included angle, the exciting force of its generation has reduced, certainly will influence the disposal ability of vibratory sieve, in addition, the corner dimension of shock electric machine axle two ends eccentric block has considerable influence to the position of shock electric machine on screen box, in the use, the size of angle must can not be done any adjustment according to the design of vibratory sieve producer.
Chinese patent ZL00244620.0 elliptically vibrating screen has proposed to adopt two different shock electric machines to realize a kind of method of balanced elliptic motion, two electrical axis are abreast across the top that is installed in screen box, can adopt short shock electric machine, also can adopt long shock electric machine, screen box is stressed simple, and motor is easy for installation.In order to realize reasonably elliptic motion, the exciting force that two motors produce differs bigger, and the exciting force of small machine is 1/5th to 1/2nd of a big motor, can not give full play of the advantage of bi-motor exciting force.When adopting long shock electric machine, be subjected to the restriction of the long motor product exciting force that domestic and international up till now production firm provides, the vibration parameters of two shock electric machine elliptically vibrating screens of designing does not reach the demand of sieving technology far away.
Summary of the invention
The objective of the invention is to overcome present the grade in the two shock electric machine elliptically vibrating screens of mass-radius product, two motors must be that " eight " font is installed and the screen box stress that causes is big, or the motor exciting force reduces, and do not wait the shortcoming that two motor exciting forces differ greatly in the two shock electric machine elliptically vibrating screens of mass-radius product, a kind of mass-radius product and two electrical axis are parallel, motor is easy for installation, exciting force is big, disposal ability is big, screening efficiency is high two shock electric machine elliptical vibration machines such as adopt are provided.
For achieving the above object, the present invention has adopted following technical scheme: the two shock electric machine elliptical vibration machines of parallel axes of the present invention, mainly by feed hopper, vibrating body, shock electric machine, the swing motor cabinet, swing motor cabinet shock-absorbing spring, compositions such as vibrating body supporting shock-absorbing spring and base, vibrating body is bearing on the base by shock-absorbing spring, a shock electric machine directly is fixedly mounted on the vibrating body, another shock electric machine is fixedly mounted on the swing motor cabinet, the swing motor cabinet is installed on the vibrating body by hinge, one group of swing motor cabinet shock-absorbing spring is installed between swing motor cabinet and the vibrating body, and two shock electric machine axis are installed parallel to each other.
The exciting force that the described shock electric machine eccentric block that is installed on the swing motor cabinet produces when rotating drives the swing motor cabinet and this shock electric machine is swung together, by designing suitable rigidity, the elastic force that swing motor cabinet shock-absorbing spring produces is swung the swing motor cabinet in certain angular range, the exciting force that the centrifugal intertia force that produces when swing motor cabinet and the swing of the shock electric machine on it and this shock electric machine produce is synthetic, make vibrating body make approximate rectilinear motion, and another exciting force that directly is fixedly mounted on the shock electric machine generation on the vibrating body makes vibrating body do circular motion, two motions are synthetic, thereby realize the elliptic motion of vibrating body.
The eccentric block of two shock electric machines can adopt identical mass-radius product, also can adopt different mass-radius products; Two shock electric machines can be done the constant speed reverse rotation, also can make constant speed and rotate in the same way.
The invention has the advantages that: 1, compare with the two shock electric machine elliptical vibration machines of mass-radius product such as present, motor is across being installed in the vibrating body top, and mounting or dismounting are convenient, vibrating body intensity height; 2, compare with the present two shock electric machine elliptical vibration machines of mass-radius product that do not wait, two shock electric machine exciting forces can equate, two motors are exerted oneself evenly, can not cause the two exciting force to differ too big; 3, two shock electric machines both can adopt identical mass-radius product, also can adopt different mass-radius products, can realize needed elliptic motion easily; But 4, both reverse rotations of two shock electric machines can be rotated again in the same way, do not need as present two shock electric machine elliptically vibrating screens, and two motors can only reverse rotation; 5, pass through to adjust the eccentric mass-radius product of two shock electric machines in the use, can make the vibrating body case obtain the oscillating movement of different ovalitys.
