2 Uras Vibrator for Sanwest All series redesigned as all-weather types with the standard specifications! You can use our vibrators under a wide variety of weather conditions. Uras Vibrators are motor-driven high-performance vibration generators. ver since they were initially launched on the market back in 1959, they have undergone a continuous evolution, and the total number of units delivered to date has broken through the 800,000-unit barrier. Uras Vibrators are making an active contribution in various industries throughout the world, but principally in the materials industry. xamples of main Uras Vibrator applications Application o. of poles P Our multi-model lineup meets the varied needs of our customers.

Custom orders are also available. eight cover Uras Vibrators feature an extremely simple mechanism whereby extremely high level of reliability. the vibrating force is led out by rotating the unbalanced weights These vibrators, usable under all weather conditions, for instance, that are attached to both ends of the induction motor shaft. have been designed to prevent the unbalanced weights from rawing on research and a proven track record that spans a halfcentury since our vibrators were originally developed, we have complete safety. At the same time they have been designed to dropping down during adjustment so that they can be handled with perfected vibrators with tough anti-vibration structures and an extend the service life of their bearings. ow our vibrators work ow many of us remember when we were children swinging a bucket around but not totally succeeding in the experiment and getting ourselves wet in the process? f we managed not to get wet, it was thanks to the centrifugal force that was exerted when we swung the bucket. Uras Vibrators work in the same way. Unbalanced weights are attached to both ends of the shaft of an induction motor (which is a regular motor) and rotated in our vibrators. This generates a great deal of centrifugal force, which is used as the vibrating force.

7 igh-frequency Uras Vibrators asy compaction with high-frequency Uras Vibrators n the vibration range from 20 to 30 z, powder acts like a fluid with a vibration acceleration of approximately twice the gravity acceleration. n contrast, at a vibration of 50 z or higher, strong compaction will occur instead of fluidization, even with a vibration acceleration that is several times the gravity acceleration. The high-frequency Uras Vibrators generate high-frequency vibration to effectively utilize this characteristic.

As shown in the photo on the right, one fixed weight and one adjustable weight whose angle can be varied are attached to each end of the shaft. To adjust the vibrating force of the Uras Vibrator, the combined eccentric moment of the fixed and adjustable weights is changed by changing the angle of the center of gravity of the fixed and adjustable weights. The required vibrating force can be set by loosening the locking bolt used to secure the adjustable weight and aligning the indicator with the required scale marking on the scale plate. The photo shows an example of an adjustment to 80% of the maximum vibrating force at 60 z. an-shaped weight system Adjustable weight Press weight adjustment (for the S-0.5-2C/-0.5-2C, 1-2C and 2-2C) ndicator ixed weight Scale plate (* The example given here shows a vibrating force of 80% at 60 z.)

Place the bump on the adjustable weight into the recess on the fixed weight and then tighten the locking bolts.

The vibrating force for this type can be set in 10 levels from a minimum of 13% up to 100% with 50 z operation, and in 6 levels from a minimum of 19% up to 100% with 60 z operation. hen shipped, it is set to 38% of the maximum vibrating force at 50 z and to 54% of the maximum vibrating force at 60 z ø8 ø8 rop-prevention wire Circular Vibration and inear Vibration a) hen generating vibration using one Uras Vibrator b Reversible variable Uras Vibrators (vibrating force varied by changing the direction of revolution) hen one Uras Vibrator is installed and used to generate vibration, revolution occurs while the position of the unbalanced weight changes instantaneously in the sequence of a, b, c, and d. This means that the vibration direction also changes in the same way, generating circular vibration. xamples of the uses of circular vibration include the prevention of blockages in hoppers as well as applications in vibration milling machines and barrel finishing machines. b) hen generating linear vibration using two Uras Vibrators a c d d c irection of vibration a ith adjustable weight ith fixed weight Operation in forward direction Operation in reverse direction Service for setting the vibrating force (Custom orders are adjusted to the vibrating force specified by the customer) Two identical Uras Vibrators set to the same vibrating force are supported by soft springs as shown in the figure on the right and their vibrator shafts are installed in parallel. These vibrators are run concurrently in mutually opposing directions. n this configuration, a synchronous torque is produced and, even without transmission through gears or other mechanisms, the two vibrators start a synchronous operation in which the forces in the horizontal direction cancel each other out while only vertical vibration is generated. This principle is used for forced packers, vibrating feeders, conveyors, screens, and many other kinds of machines that apply vibration. a b d c b c b d a 14 15

10 avibration Prevention Transmission of vibrations to the floor The transmission of vibrations differs depending on the vibration frequency and spring constant of the vibration-proof springs. The transmission of vibrations from vibrating machinery to the floor must be minimized. The table on the right gives the general selection guidelines. (1) A vibrating machine must be operated at a vibration frequency at least two times higher than the resonance point. n fact, a vibration frequency that is 5 to 10 times higher is used as indicated in the table on the right. (2) The vibrating force transmitted to the floor is expressed as the product of the single amplitude and spring constant. Therefore, the total load applied to the floor is the sum (±) of what is exerted by the weight of the machine itself plus that exerted by the vibration. (3) Because the vibration of a vibrating machine is temporarily increased when the machine passes through the resonance point when it is stopped, it will be greater than the values given in the table on the right. Safe values for the total load are 1.5 times the machine weight for a 2-pole or 4-pole vibrator, and 2.0 times the machine weight for a 6-pole or 8-pole vibrator. (4) ote that when the resonance point of the floor and building is close to the vibration frequency of operation (especially when the vibration frequency is changed by the vibration feeder), strong vibrations may be generated in locations other than the installation location due to resonance, possibly causing trouble. o.of requency Poles (z) 2P 4P 6P Vibration requency f (z) Sag of Spring upon ounting δ (mm) Spring Constant k (/mm) *1 Resonant requency of system f 0 (z) ouble Amplitude 2α (mm) * esignation Power Supply Three-phase S Single-phase Type Standard model igh-frequency model S Stainless steel surface Version Previous ew ounting method Blank Standard V lange-type (Vertical model) orizontal model force ote 4 o. of poles 2 Two poles 4 our poles 6 Six poles 8 ight poles Additional code Blank esign B revision C order Special orld standard Corrosion-proof (for indoor/outdoor use) Protruding shaft otes: 1.
