General guidelines for belt drive guard designs. • Complete enclosure of the drive belt system should be mandatory – the guard should limit any entry or access in ALL directions. • Ventilation – as all V-belt drives generate heat, the heat needs to be dissipated through the ventilated sides, and possibly bottom, of the drive guard.

Dimensions of V-belts and pulleys together with basic design data are covered in this manual. This manual does not apply to automotive and agricultural drives.

V-belt Drives There is no slipping under normal loads. The linear speed of the pitch line of both sheaves is the same as and equal to the belt speed, vb. vb = R1ω1 = R2ω2 •B Rut 1 = D1/2 and R2 = D2/2 vb = D1ω1 / 2 = D2ω2 / 2 The angular velocity is: ω1/ω2 = D2/D1 V-belt Drives con't 4.

V-belts and flat belts employ the use of friction to transmit power while timing belts physically engage the pulley via teeth and grooves. A friction drive

string, or ideally with a laser alignment tool. A properly aligned V-belt drive has four points of contact between belt and sheaves (see Figure 4). Total angular and parallel misalignment in a V-belt drive system should be kept within ½-degree or 1/10-inch per foot of belt span.

V-Flat Drives A V-flat drive is a V-belt drive which uses a flat pulley on one or more shafts. Single Classical V-Belts, Banded Classical V-Belts, Banded Wedge V-Belts and Hex belts are suitable for V-flat drives. Individual Wedge V-Belts are not recommended due to the narrow bottom width leading to inherent instability on the flat pulley.

The V-belt comprises a belt body having an inner compression section and an outer tension section, and longitudinally extending tensile elements embedded in the V-belt between the sections.

Never apply belt dressing as this will damage the belt and cause early failure. Tension Measurement Procedure 1. Measure the belt span (see sketch). 2.

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

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.

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
