Checking adjusting and refitting drive belts How a Car Belt Resources Conveyor Belt Training Shipp Belting

Drive belts always stretch a little in use because of the strains put on them by driving the water pump and generator as well as the fan itself if it is in the system Age and continual flexing also cause belts to crack and deteriorate Stretching slackens a belt so that it slips on the pulleys A cracked belt will eventually breakWhen reducing counter weight to relax conveyor belts in concave curves or just to get the proper sag on rollers for tracking it is imperative that the drive pulleys on the conveyor be lagged with a 60 durometer rubber material to prevent slippage of the conveyor belt on the drive pulley

History The mechanical belt drive using a pulley machine was first mentioned in the text the Dictionary of Local Expressions by the Han Dynasty philosopher poet and politician Yang Xiong 53 18 BC in 15 BC used for a quilling machine that wound silk fibers on to bobbins for weavers shuttl The belt drive is an essential component to the invention of the spinning wheel3 To adjust the position of drive pulley and bend pulley The mounting position of all conveyor pulleys must be perpendicular to the centerline of longitudinal direction of conveyor belt and too much offset leads to belt deviation The adjustment method is similar to that of carrier roller group

As a rough guideline use 1 5 elongation for textile belts and 0 2 for steel cord belts Note For long distance conveyors dynamic start up calculations may be required because not all elements are set in motion simultaneously due to the elastic properties of the conveyor beltThe efficiency of standard V belts will decrease over time from a peak of 95 98 to less than 93 due to ageing and failure to adjust the belt tension Cogged belts have a greatly reduced bending resistance compared to standard V belts and can be used on the same pulleys as equivalent V belts

A loss of lagging material off a drive pulley will cause a belt to swing on the track It can move from the right to the left If you find that you have to adjust a roller in the opposite way as described before so if you tighten on the right side and the belt moves to the right it is a sign that your belt In a friction drive system the pulley moves slightly faster than the belt If not controlled belt creep in a friction drive metal belt results in a loss of repeatability affecting the precision of the application Using Type I or Type II timing pulleys is the best way to avoid
