Abstract
The utility model relates to a two-shaft multi-trajectory variable amplitude vibrator which belongs to the field of vibration machinery. The two-shaft multi-trajectory variable amplitude vibrator can solve the problems that the motion trajectories and the amplitude of the vibrator on a vibrating screen are relatively stable and the hole blockage phenomenon is easy to occur. Two transmission shafts which are arranged in parallel are arranged on a box body of the vibrator, an eccentric block is arranged on each shaft, and the two transmission shafts are meshed and connected through gears; the gears on the two transmission shafts have different numbers of teeth, and the eccentric masses of the eccentric blocks are different; and the eccentric masses of the eccentric blocks on the two transmission shafts are in direct proportion or inverse proportion with the number of the teeth of the gears. The multiple motion trajectories and the variable amplitude, which are generated by the vibration in the structure, can periodically change the stability in vibration of a screen box of the vibrating screen so as to enable the screen separation of sticky and wet materials to be vital, stir a material layer which is deposited stably and clear a blocked hole, thereby obviously improving the screen separation efficiency. The two-shaft multi-trajectory variable amplitude vibrator is suitable for the vibrating screen for screen separation of various sticky and wet materials.
Description
Technical field
The utility model belongs to the vibrating machine field, mainly relates to the diaxon multiple mark change amplitude vibration device that vibration screening machinery is used.
Background technology
Use the vibratory sieve of diaxon vibrator, two power transmission shafts generally are to connect through isoparametric gears engaged, and the eccentric mass of the eccentric block of adorning is equal on every power transmission shaft, and the movement locus of screen box is a linear.The movement locus of vibratory sieve screen box and amplitude are all more stable, so the efficient of screening operation also is very stable.But, relatively more sticking wet if the material that is sieved contains certain moisture, on compass screen surface, form the more stable bed of material of one deck easily, stoppage phenomenon influences normally carrying out of screening operation.Have only the bed of material that destroys stable operation, material is stirred again and make up, just can obtain screening effect preferably.
Summary of the invention
The purpose of the utility model provides a kind of diaxon multiple mark and becomes the amplitude vibration device, and this vibrator can carry out periodic multiple mark and become amplitude ground screening operation the material on the vibratory sieve compass screen surface effectively, improves the screening efficiency of vibratory sieve.
The utility model is realized through following measure; Mainly form by casing, power transmission shaft, gear and eccentric block; It is characterized in that: two power transmission shafts that are set up in parallel are housed on the vibrator casing, eccentric block all is housed on the every axle, connect through gears engaged between two power transmission shafts; The number of teeth that two power transmission shafts cog and the eccentric mass of eccentric block are unequal; Cog what of the number of teeth of two axles are that the eccentric mass of eccentric block on the many power transmission shafts of one of following two kinds of forms: a, the gear number of teeth is big with the corresponding relation of eccentric block eccentric mass, and the eccentric mass of eccentric block is little on the few power transmission shaft of the gear number of teeth; The eccentric mass of eccentric block is big on the few power transmission shaft of b, the gear number of teeth, and the eccentric mass of eccentric block is little on the many power transmission shaft of the gear number of teeth.Two power transmission shafts of this vibrator can not be contained on the casing, are directly installed on the side plate of vibratory sieve screen box.
The beneficial effect of the utility model is, when working under two drives of power transmission shaft at transmission gear for electric motor of vibrator, under the effect of meshing gear, with opposite direction rotation.Because the speed of two axle rotations is different different with the eccentric mass of eccentric block, so the movement locus of vibrator is periodic time dependent many elliptical trajectories, its amplitude also is periodically time dependent.The do more physical exercises amplitude of track and variation, periodically-varied vibratory sieve screen box vibration stable, make the screening of adhesional wetting materiel go out to appear life, the bed of material of stably depositing is stirred, plug-hole has obtained cleaning, screening efficiency obviously improves.Be applicable to the vibratory sieve of the various adhesional wetting materiels of screening.
Description of drawings
Fig. 1 is the vibrator sketch map that the eccentric mass of eccentric block on two power transmission shafts is directly proportional with the gear number of teeth, and Fig. 2 is the eccentric mass of eccentric block on two power transmission shafts and the vibrator sketch map that the gear number of teeth is inversely proportional to.1 is that a gear, 2 on the power transmission shaft is the eccentric blocks, the 3rd on the power transmission shaft among the figure, the gear on another power transmission shaft, the 4th, the eccentric block on another power transmission shaft, the 5th, casing.
The specific embodiment
Embodiment below in conjunction with description of drawings the utility model.Mainly form, two power transmission shafts that are set up in parallel are housed on vibrator casing 5, eccentric block all is housed on the every axle, be connected with a joggle through gear 1,3 between two power transmission shafts by casing, power transmission shaft, gear and eccentric block; The number of teeth that two power transmission shafts cog and the eccentric mass of eccentric block are unequal; The eccentric mass of eccentric block is big on the many power transmission shaft of the gear number of teeth, and the eccentric mass of eccentric block is little on the few power transmission shaft of the gear number of teeth; The eccentric mass of eccentric block is big on the power transmission shaft that perhaps the gear number of teeth is few, and the eccentric mass of eccentric block is little on the gear number of teeth power transmission shaft how.
Claims (2)
1. a diaxon multiple mark becomes the amplitude vibration device; Mainly form by casing, power transmission shaft, gear and eccentric block; It is characterized in that: two power transmission shafts that are set up in parallel are housed on the vibrator casing, eccentric block all is housed on the every axle, connect through gears engaged between two power transmission shafts; The number of teeth that two power transmission shafts cog and the eccentric mass of eccentric block are unequal; Cog what of the number of teeth of two axles are that the eccentric mass of eccentric block on the many power transmission shafts of one of following two kinds of forms: a, the gear number of teeth is big with the corresponding relation of eccentric block eccentric mass, and the eccentric mass of eccentric block is little on the few power transmission shaft of the gear number of teeth; The eccentric mass of eccentric block is big on the few power transmission shaft of b, the gear number of teeth, and the eccentric mass of eccentric block is little on the many power transmission shaft of the gear number of teeth.
