Effect of centrifugal tension on power transmission in belt drive

Usually, power transmission is proportional to belt speed.
However, at very high belt speeds which are usually above 1500 m/min, the power decreases with increase in the belt speed due the to rapid rise of centrifugal force acting on the belt. This centrifugal force reduces the pressure between the belt and the rim of the pulleys, and thus, move the belt away from the pulley and reduce the wrap angle. Therefore, the belt tensions and power transmission also are reduced.
