Description
Technical field:
The invention belongs to the vibration screening machinery field, mainly relating to linear vibrating screen housing seat formula vibrator is split type, as can to improve the vibratory sieve screen frame greatly rigidity, two component body seat formula vibrator linear vibrating screens of raising vibrator motor synchronizing operational effect.
Background technology:
In the box vibrator of existing linear vibrating screen, general what use is that diaxon motor synchronizing form or band gear force two kinds of synchronous versions, realization all be the straight-line oscillation track.These two kinds of box vibrators, its casing is the foundry goods of an integral body, and two main shafts are installed on the casing of an integral body through four bearings, and four eccentric blocks are installed on the main shaft respectively.Along with the increasing of vibratory sieve model, its vibrator appearance and size and weight are also strengthening, and all make troubles for like this maintenance, installation, debugging, and changing bearing also has certain degree of difficulty.In addition, the vibrator of this form, because of receiving structure and foundry goods reason, the increasing of two alignment of shafts distances receives certain restriction.When needing many vibrators for large-scale vibrating screen, vibrator can only be on a whole crossbeam on the screen frame arranged in series, the integral rigidity of screen frame is weakened, be prone to early stage the damage.Most critical be that less because of the centre-to-centre spacing of two main shafts when adopting the box vibrator of diaxon motor synchronizing in large-scale linear vibrating screen, the synchronism that makes the screen(ing) machine operation is instability very, and screen(ing) machine torsional oscillation or vibrating deflection are changed.The good of motor synchronizing operation is the important technology index of diaxon motor synchronizing linear vibrating screen with bad, so; According to screen(ing) machine model size and motor synchronizing theory demand; The centre-to-centre spacing of two main shafts of adjustment vibrator, to improving the motor synchronizing operational effect, the stability that improves linear vibrating screen is necessary.
Summary of the invention:
The purpose of this invention is to provide a kind of two component body seat formula vibrator linear vibrating screens; Two main shafts of this linear vibrating screen vibrator are split settings; Its casing is mounted on two crossbeams; Improve the integral rigidity of vibratory sieve, made screen frame stress and vibrator motor synchronizing respond well, can realize the maximization of linear vibrating screen.
The present invention realizes through following measure.Linear vibrating screen mainly is made up of screen box, compass screen surface, vibrator, transmission gear for electric motor and base vibration absorber etc.; It is characterized in that: the screen frame of screen box is provided with two vibrator mounting rails that spacing is bigger, and one group of single shaft seat formula vibrator respectively is housed on each mounting rail.The main shaft of single shaft seat formula vibrator is installed on the casing of vibrator through two bearings, and two eccentric blocks are installed in the two ends of main shaft.Every group of single shaft seat formula vibrator is cascaded at the screen(ing) machine width by a plurality of single shaft seat formula vibrators and forms, and the direction of rotation of two groups of single shaft seat formula vibrator main shafts is opposite, is connected with the transmission gear for electric motor that is positioned at the screen box one or both sides respectively.Assemble together through bearing beam in the middle of two groups of corresponding single shaft seat formula vibrators.For adapting to the variation of distance between two vibrators that cause by processing or alignment error, guarantee the centre-to-centre spacing of two vibrators, in the end of bearing beam, be provided with the wedge shape governor motion of fine-tuning two groups of vibrator joint gaps.
According to the requirement of the specifications and models and the screen(ing) machine parameter of vibratory sieve, one group of single shaft seat formula vibrator on each mounting rail can be cascaded at the screen(ing) machine width by one, two, three, four or a plurality of vibrator and form.The length of bearing beam is changeable with the requirement of the centre-to-centre spacing of two groups of vibrators, can require to be provided with according to vibratory sieve model size or motor synchronizing, and the wedge shape governor motion of bearing beam end can be arranged on the one or both ends of bearing beam.The wedge shape governor motion is made up of wedge, adjusting screw(rod) and Fixed Nut, and the wedge that screw rod passes between fixing screw and bearing beam and the vibrator casing flexibly connects; Install for ease of the moving of wedge, adjustment and bearing beam, wedge is provided with the installing hole of strip.
The invention has the beneficial effects as follows; Because with the vibrator of a casing of vibratory sieve twin shaft, split is two groups of single shaft seat formula vibrators, is installed in respectively on two mounting rails; So the centre-to-centre spacing between two groups of vibrators does not receive the restriction of casing, can strengthen or reduce according to designing requirement.The motor synchronizing effect of two groups of vibrators can obviously improve, and makes straight-line track more stable.In addition, two groups of vibrators lay respectively on two mounting rails, and are connected and fixed through bearing beam, the synthetic and vibrator lower margin set bolt stress equalization of the exciting force that vibrator diaxon eccentric block is produced, and the integral rigidity of vibratory sieve is strengthened.Having vibrator can wide spacing setting, rational in infrastructure, synchronous effect good, vibrator installation, maintenance, characteristics such as easy to adjust.Be applicable to the large-scale linear vibrating screen of various uses.
