DRIVE INFORMATION FOR FLATWIRE CONVEYOR BELTS
SPROCKET DRIVE
Sprockets provide a positive drive of the belt and help keep the belt properly aligned. Conveyor lengths of 50' or less for standard weight belts and 100' or less for heavy duty belts are generally recommended for sprocket drive.
Center to center spacing of sprockets should not exceed 6". In heavy load conditions, spacing of the sprockets should be as close as possible. Sprocket spacing greater than 6" can lead to premature belt failure due to the excessive straon on the connecting rods. Drive sprockets should be keyed to the shaft and tail sprockets should be collared on the shaft to permit free idling - one tail sprocket should be keyed to assure shaft rotation.
FRICTION DRIVE
Friction driving of the belt is preferable to sprocket drive when the loads are relatively heavy and the conveyor lengths are long. Lagged flat face pulleys of as large a diamter as practical are recommended for friction drive. A friction drive system evenly distriubutes the drive tension across the belt and are not subject to rod wear as in a sprocket driven system. To prevent tracking problems, friciton driven belts must be run on an accurately alinged conveyor.
SPROCKET LOCATION DIAGRAM
Proper sprocket location as shown in the drawing below is essential for smooth belt operation. Sprocket teet must always drive against the connector rods. This is accomplished by locating the drive sprockets so that the teeth are in the odd numbered mesh opening and locating the Tail sprockets so that the teeth are in the even numbered mesh openings.
It is very important when mounting sprockets to have the long side of the hubs all facing the same direction. Avoid placing drive sprockets so that they drive on the outside the mesh openings.
