Groove V-belt 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.

Groove V-Belt Double Pulley Features:
Double Groove V-belt pulleys are excellent for distributing torque to many belts. They are available with a single or double groove for varying power transmission capacities. The double grooves ensure proper torque distribution across the v-belts and provide mechanical redundancy.
Double Groove V-belt pulleys are made from solid cast iron and are statically balanced. They are designed to work with “A” series belts. This allows them to increase the efficiency and life of your drive. They are also available with adjustable pitch.
Double Groove V-belt pulleys have many features that make them the best option for your application. They are designed with thin cross sections that allow them to operate over smaller pulleys, which is advantageous for many applications. In addition, their design can accommodate larger ratios and shorter center distances, saving weight and space.
Double Groove V-belt pulleys are great for industrial applications because of their wear resistance. The V-shaped belt wedges tightly into the Groove, increasing friction and operating torque. The V-belts are also designed to prevent slipping. Wear grooves can be a problem in some machines, however.
Double Groove V-belts provide excellent power transmission, and their heavy-duty wrapped covering makes them durable and resistant to heat, grease, and abrasive wear. Besides their superior power transmission capabilities, they also provide smooth horsepower transmission.
