Designed originally for operations involving timing and synchronization, timing belts have proved capable of trans足 mitting power and performing other operational functions. Grip-Tite timing belts function like timing chains or gears with great success on machines with such extremes in service requirements as electric typewriters, rugged pug mills, gasoline pumps, mud pumps, bakery machinery, lake dredges-BUT all positive and accurate in all their timing. Loading capacities of timing belt drives range from fractional horsepower to over 600 horsepower. Their torque loads range from thousands of foot-pounds to loads in inch-ounces. They have a high horsepower-to-weight ratio. The precision-molded teeth of Grip-Tite timing belts function like a timing chain or gears. Positive engagement with the mating axial grooves on the pulleys occurs in a smooth, rolling manner providing negligible friction. There is no take-up or slippage. No metal-to-metal contact is present so no lubrication or oil-retaining devices are required. Reduced bearing loads are achieved because there is less friction and reduced tension requirements with Grip-Tite timing belts. There is Virtually no backlash. These efficient timing belts often outperform precision gear drives. These belts are versatile in application. Space requirements can be greatly reduced with Grip-Tite timing belts, which permit use of small pulleys, short centers, narrow belts and high capacity. Timing belts are made in six stock pitches. On the belt, pitch is the distance between tooth centers and is measured on the pitch line of the belt On the pulley, pitch is the distance between groove centers and is measured on the pulley's pitch Circle The pitch line of a timing belt is located Within the cable tension member. The pitch circle of a timing belt pulley coincides with the pitch line of the belt mating with it. The pulley's pitch diameter is always greater than its face diameter. To facilitate selection, ordering and Identification of timing belts, the designations have been standardized Each stock pitch is Identified by Its code letter-such as H or XH. This letter represents not only a particular pitch, but also the belts construction for that particular pitch, the number and diameter of the cable tension member, the thickness and type of the facing material, the rubber compounds used. Timing belts are marked In this manner
