A stepped v-belt pulley provides a low-cost and efficient means of enabling a selection of speeds. Speed changes are made when the drive is stationary; the belt tension must first be released and manually relocated in an alternative set of grooves. In many arrangements, the pulley center distance remains virtually unchanged. Stepped v-belt pulleys are produced from a one-piece aluminum casting and are machined with groove profiles to accept standard v-belts. Where the diameters allow, wedge belts may also be used.

Stepped V-Belt Pulley Application

The typical step pulley consists of 3 to 5 grooves. This type of step pulley is found on equipment such as drill presses, lathes, and milling machines, where different operational speeds can be produced simply by changing the belt to a different pulley size. The step pulley is continuously operated in pairs, and when the belt is changed on 1 pulley, it is also changed on the corresponding pulley on the other side of the belt.

When it has been determined that the speed should be regulated on a specific step pulley-equipped machine, adjusting the rate is usually straightforward. With the motor in the off position, open the belt cover. Take note of where the belt is currently positioned on the pulleys. Remember, a small pulley driving a larger pulley will result in more power but less speed output. Conversely, a large pulley driving a smaller pulley will have more speed output but less power.

Stepped V-Belt Pulley Features

Stepped v-belt pulleys offer high concentricity and are available in single and double-row configurations. They can also be used in pairs and any combination. Stepped v-belt pulleys have an inside diameter of 0.15″ smaller than the outside diameter.

Stepped v-belt pulleys are designed with 2 pulleys, 1 fast and 1 loose. The short pulley is keyed to the driven shaft, whereas the loose pulley rotates freely on the post. This design is suitable for multi-machine applications where each machine uses a single power source.

Stepped cone pulleys are another type of stepped v-belt pulleys. These pulleys have multiple diameters, making them great for applications where the speed of the driven shaft is frequently changing. They are also commonly used for applications where different rates must be achieved using the same belt.

Stepped v-belt pulleys have unique geometry, making them an excellent option for high-speed power transmission. The trapezoidal shape helps guide the v-belt as it passes the pulley. The grooves on the top and bottom sides of the v-belt provide additional surface contact with the pulley. They also increase the wear resistance of the belt. They can be ordered in both standard and custom sizes.

The stepped v-belt pulleys are a common type of v-belt pulleys made of high-quality materials. Its design is a common choice for many industrial applications. Its flexibility, durability, and low cost make it a good choice for many different uses.
