An engine timing belt is a fiber reinforced, toothed drive belt manufactured using durable compounds such as highly saturated nitrile. The timing belt allows the crankshaft to drive the camshafts in the cylinder head at half the RPMs of the crankshaft. The camshafts then open and close the engine's intake and exhaust valves in time with the

As a general rule, sheave misaligment on V-belt drives should be less than 1/2˚ or 1/10" per foot of drive cen-ter distance. Misalignment for synchronous, Polyflex® and Micro-V® belts should be within 1/4°or 1/16" per foot of drive center distance. The greater the misalignment, the greater the chance of

V-Belt Drives Section 1 2. Select Replacement Belts B-1, B-2, B-3, B-4 After you have made any necessary corrections in your V-belt drive elements, the next step is the selection of the

In general, flat belt drives are horizontal and not vertical. 7. V belts are endless which results in smooth and quiet operation even at high operating speeds. 8. The force of friction between the surfaces of the belt and V grooved pulley is high due to wedge action which results in increase in

V-Belt sheaves of close grain, high-tensile cast iron are machined to provide safe, vibration-free operation at speeds up to 6500 FPM. Made to order sheaves of ductile iron material can be provided for speeds up to 10,000 FPM. V-Belt drives are only the beginning of what Wood's can do.

Gates Super HC V-Belts combine modern high capacity material with the revolutionary "narrow" cross section pioneered by Gates. They can transmit up to 3 times the horsepower of conventional V-belts in the same drive space—or the same horsepower in 1/2 to 2/3 the space. Super HC belts can be used on all industrial integral horsepower drives.

V-belt tensioning For the initial installation of optibelt RED POWER 3 V-belts, the same methods are used as for standard Optibelt V-belts. The tension values are to be calculated on the same basis or to be taken from the table on page 147. Once correctly tensioned optibelt RED POWER 3 V-belts need no re-tensioning. Application areas

V-belt Drive Design Process. 1. Rated power of the driving motor/prime mover. 2. Service factor based on type of driver and driven load. 3.

V-Belt Drives Section 1 2. Select Replacement Belts B-1, B-2, B-3, B-4 After you have made any necessary corrections in your V-belt drive elements, the next step is the selection of the correct replacement belts. When replacing sets of V-belts, here are some very important reminders: • Never mix new and used belts on a drive.
