Basics of belt drives Power transmission belting has been used for more than 200 years. The first belts were flat and ran on flat pulleys. Later, cotton or hemp rope was used with V-groove pulleys to reduce belt tension. This led to the development of the vulcanized rubber V-belt in 1917. The need to eliminate speed variations led to the development of synchronous or toothed belts about 1950 ...

Belt Drive Advantages. Wide range of speeds available. Belts permit flexibility ranging from high horsepower drives to slow speed and high speed drives. Belt drives are less expensive than chain drives for low horsepower and low ratio applications. Belts require no lubrication. Single belt drives will accept more misalignment than chain drives.

gravity and will "drift" toward the low side unless a compensating force of some kind is exerted on that belt. Pulleys/Rollers/Idlers All pulleys, snub rollers, carrying idlers, and return idlers must be square with the frame (perpendicu-lar to belt center line), parallel to each other and level. "Squaring" with the frame is a good preliminary adjustment. The final adjustment, however ...

Tail, deflection, snub, guide and tension pulleys are usually made with cylindrical shape. Rollers and pulleys that run against the coated conveying side of the belt should normally be cylindrical. Driving pulleys The principal function of the driving pulley is to transfer the peripheral force from the driving system to the conveyor belt. If the driving pulley is cylindrical-conical in shape ...

Belt tension must be great enough to prevent slip-page between the drive pulley and belt. Tension must also be enough to cause the belt to conform to the crowns, if present. Slippage will cause excessive wear to both drive pulley lagging and the belt. Further, an excessive heat buildup on the drive pulley lagging can result in rubber reversion ...
