Precision Timing Belt

The arcuate timing belt is made of plastic bonded to metal tape. It runs on a crowned pulley to give improved tracking and obviate the need for pulley flanges.

Crowned pulley 10 has gear teeth engaged with mating arcuate teeth on belt
11. The belt teeth are formed in plastic having a flat back on which is bonded metallic tape 12 to give added strength.

The beveled belt and pulley teeth enable better tracking of the belt between two given centers. Flanges are not necessary to keep the belt from working off the pulley, since the belt tends to move toward the crown of the pulley.
