· A case study has been conducted on the wear problem of a set of large helical gears of a ball mill used for cement production at the Shiraz Cement Plant. The ball mill has a nominal capacity of 80 t h −1. The overall diameter and length are respectively 4000 mm and 12990 mm. The total weight of the ball mill when fully charged is about 280 t.
· Excessive vibrations on rotating equipment like pumps, gearboxes, turbines and compressors are a clear sign that the equipment is not functioning properly. Equipment that is showing excessive vibrations will most likely not achieve the expected lifespan, and can be the source of unscheduled downtime or dangerous situations. Therefore, it is important to find the root .
Gear problems looseness Rubs Oil whip Blade Pass Pipe strain Rolling element bearing defects Facts About Vibration Vibration is movement relative to a reference position, such as the center line of a shaft on rotating equipment Vibration is a result of an excitation force or forcing function and may be either random or periodic Vibration analysis can often pinpoint a failing element of a ...
A case study of a gearbox. Late last fall, routine monitoring of a gearbox showed an increase in overall vibration levels, which was not apparent in the spectra. If the gearbox failed during the winter, the process plant would not have been able to start up again until spring. Plant engineers called us in to determine whether the gearbox would run through the winter. The investigation ...
