Sprockets And Idler Wheels

Product Description

Exim Engineering offers sprockets and idler wheels made from plastic (PA6), cast iron, and steel (ST52), depending on the specific application. Split plastic sprockets are the most commonly used type.

The design of the sprocket is determined by the type of flat-top chain being used. Drive sprockets have a keyway for secure power transfer, while idler wheels do not have this feature. Alternatively, a deflection roller can be used instead of an idler wheel.

The benefit of split sprockets is that technicians do not need to remove the sprocket from the shaft to perform maintenance. The sprocket is separated for removal, with no other components impacted.

The stresses on the base of a tooth in a sprocket are significantly lower than those in roller chain sprockets. This difference is related to the sprocket width, determined by the flat top chain. Therefore, plastic is a suitable material for these sprockets. Additionally, plastic sprockets can be used in various applications under differing conditions because plastic is more chemically resistant.
