Abstract
Belts are the cheapest utility for power transmission between shafts that may not be parallel. Power transmission is achieved by specially designed belts and pulleys. The demands on a belt drive transmission system are large and this has led to many variations on the theme. They run smoothly and with little noise, and cushion motor and bearings against load changes, albeit with less strength than gears or chains. However, improvements in belt engineering allow use of belts in systems that only formerly allowed chains or gears.
V belts (also known as V-belt or wedge rope) solved the slippage and alignment problem. It is now the basic belt for power transmission. They provide the best combination of traction, speed of movement, load of the bearings, and long service life.
Drive commences by the power source applying a torque to the shaft of the small drive pulley, causing it to rotate at a steady speed n1. The tension in the 'tight' upper straight strand will then exceed while the tension in the 'slack' lower strand will become less than. This tension difference applies a torque to the drive load pulley, equilibrating the load torque, while the pulley rotates at uniform speed n2, thus transmitting the power to the load pulley shaft.
Introduction
A Belt is a looped strip of flexible material, used to mechanically link two or more rotating shafts. They may be used as a source of motion, to
