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.

types of belt drives: 1-light drives, these are used to transmit small powers at belt speeds up to about 10 sec m as in agricultural machines and small machines tools. 2-medium drives, these are

1 Belt drives provide flexibility in the positioning of the motor relative to the load. Pulleys (sheaves) of varying diameters allow the speed of the driven

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 

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 146. Once correctly tensioned optibelt rED POWEr 3 V-belts need no r e-tensioning. application areas

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

The V-Belt Drive is industry’s most popular means of power transmission. It is easy to select, simple to install, and will provide years of reliable performance. Even when misapplied,

V-belts, as simple as they seem, are marvels of technology. A properly designed and installed V-belt drive should deliver a long service life—unless there's an 

Q. What is the maximum speed that a drive belt can safely handle? A. A V-belt squealing is usually caused by belt slip, often due to undertensioning.

θA is the wrap angle of pulley A. θB is the wrap angle of pulley B. RA is the effective radius of pulley A. RB is the effective radius of pulley B. C is the distance between the centers of pulleys A and B. Open Belt. When you set Drive type to Open belt, the block calculates the wrap angle of the belt around each pulley as: θ A = π + 2 ∗

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.
