2BK Series Cast lron Groove Sheaves Double Pulley
A double pulley is a type of pulley system that consists of two pulleys mounted on a common axle or shaft. The two pulleys are typically of different sizes, with the larger one known as the drive pulley and the smaller one known as the driven pulley. A belt or rope is wrapped around both pulleys, and when the drive pulley is rotated, it causes the driven pulley to rotate as well. This arrangement allows for mechanical advantage, where force can be multiplied or speed can be reduced, depending on which pulley is used as the input and which is used as the output.
Double pulleys are used in a wide range of applications, from simple machines such as manual cranes and hoists, to more complex systems such as conveyor belts, elevators, and heavy machinery. In this article, we will explore the different types of double pulleys, their applications, and how they work.
