The present invention is directed to an adjustable counterweight assembly for association with a vertical, rotatably mounted shaft. We offer screens that meet specifications from these and other industry organizations. In operation, the appropriate weights 32 are bolted to the upper eccentric weight assembly 14. Thus, an easily adjustable counterweight assembly has been disclosed. After tightening the weight clamp bolt, double-check to make sure that the weight didn’t move while being tightened onto the shaft, if the punch mark is off the desired scale plate mark, loosen the bolt and reposition the outer weight. Parks and Recreation The bowl vibratory machine has weights attached to the top and bottom of a vertical shaft mounted to the center column of the bowl that can be added and subtracted from the top and bottom weight carriage. First, let’s delve into everyone’s favorite subject, math, to get a better understanding of the importance of weight setting and its impact on the operation of the vibrator and, more importantly, the piece of equipment. Even unusual shapes and sizes discharge easily. Please enter your name, email and a comment. Vibration is accomplished by eccentric weights on the upper and lower ends of the motion-generator shaft. If the openings are tight compared to the size of the media, forward feed needs to be reduced to eliminate media carryout over the screen deck. The slots 64 and the pins 66 and 68 are so arranged that the pins fit into the slots without substantial play. These First and second eccentric weight assemblies are fixed to the shaft. A counterweight assembly on a vertical, rotatably mounted shaft which is adjustable. It’s critical that what is done to one end of the vibrator must be done to the other end. This completes our step-by-step process on how to adjust the weights on a rotary electric vibrator. Adjustments in finishing action are easily made by varying lead angle and motor weight settings. Want to see these steps in action? JavaScript seems to be disabled in your browser. When the screen opening sizes are much larger than the media, forward feed can be increased. Increasing the weights and positioning the top weight carriage 90 degrees behind the bottom weight carriage is a good starting point for faster unload. a first eccentric weight assembly fixed to the shaft; a second eccentric weight assembly displaced from said first eccentric weight assembly along the shaft, said second eccentric weight assembly including a support fixed to the shaft to extend laterally of the shaft, said support having a ring of slots displaced laterally of the shaft, a first eccentric weight rotatably mounted about the shaft and having a first pin extending to said ring of slots, a second eccentric weight rotatably mounted about the shaft and having a second pin extending to said ring of slots. In the preferred embodiment, slots 64 are defined at 5" intervals. Rotation of the top weight creates vibration in the horizontal plane, which causes material to move across the screen cloth to the periphery. Time-tested technology provides three-dimensional Vibro-Energy motion for all SWECO Finishing Mills. In adjustment of the eccentric weight assembly 40, maximum eccentricity is achieved by lining the weights 54 and 56 up with one another. Consequently, changing and adjusting such systems is inconvenient, requires experience and takes substantial time. Additionally, SWECO offers Gyratory Sifters, Pharmaceutical Aseptic Separators, Decanter Centrifuges and aftermarket parts and screens for multiple industries. The unbalanced is the weight of the rotating mass x the distance from the center of gravity of that mass to the center of rotation, units being inch-pounds. Such devices typically are advantageously operated using a variety of vibration amplitudes and lead angles. Manufactured in the USA for over 25 years, Industry Use One of the eccentric weight assemblies includes a support fixed to the shaft to extend laterally of the shaft.
