Belt should be stored in a cool dry place out of the direct sunlight at ambient temperatures preferably below 30 degree celsius. Belt should not be stored on the floor or near windows, radiators or airflow from heaters. Some fibres used for strengthening of belts are subject to shrinkage in storage, the amount depending on temeperature, relative humidity and storage time.
During storage avoid excess weight on belts and also avoid distortion of belts. When hung on pegs, the longer belts should be coiled so that the loops are not greater than approximately 2500 mm in circumference. Pegs should be crescent shaped and larger enough to avoid compression set from corners or from acute bends of the belt.
The proper tension for operating a V-belt drive is the lowest tension at which the belts will not slip at peak load conditions. For applications without a variable frequency drive (VFD) or starter, and the motor is “ran across the line”, the tension must be able to handle the increased motor torque during startup. For slow start VFD applications, the belt tension must handle the actual brake horsepower of the fan at the fan shaft.
For V-belts, after initial installation tensioning, a re- tensioning of the belt is recommended after a period of operation, usually one to two days. Belt tension should be checked periodically, about every three to six months. A more frequent inspection for noise or vibration is recommended. Under-tensioned belts can slip, generating heat that often results in cracking and eventual belt failure. Over-tensioned belts will create excessive stretching in the belt and reduce both belt and bearing life as the bearing loads will increase. While checking the belt tension, the belts should also be inspected for any cracks or fraying as these indicate belt wear.
