SPROCKET DRIVE

grabcad

Sprockets are used in the conveyor system to drive the chain. Conveyor sprockets typically have an odd number of teeth although sprockets with an even number have become more prevalent over the last thirty years. Most sprockets are made from fabricated steel and are parallel or taper keyed to a through shaft. Conveyor sprockets are also available in double pitch and shear pin varieties. Double pitch sprockets wear evenly and offer a longer service life than standard sprockets. Shear pin sprockets break when overloaded, stopping the conveyor and saving considerable expense and downtime.[
