Sprockets and idler wheels for flat top chains Sprockets and idler wheels for flat top chains are available in single-piece and split versions for the entire FLEXON range. In addition, iwis also manufactures sprockets and idler wheels made from plastic PA6, cast iron or steel ST52, depending on the application. Split plastic sprockets are the most commonly used version. The flat top chain used determines the sprocket design. Drive sprockets have a keyway for positive-locking power transmission, whereas idler wheels do not have a keyway. As an alternative, a deflection roller may be used instead of an idler wheel. The advantage of split sprockets is that technicians do not have to remove the sprocket from the shaft to carry out maintenance work. The sprocket is simply split for removal and no other components are affected. The forces in the sprocket that are exerted on the base of the tooth are much lower than those found in the sprockets used for roller chains. This is due to the sprocket width, which is in turn dependent on the flat top chain, so plastic is a suitable material here. Since plastic is more chemical-resistant, plastic sprockets are suitable for a wide variety of applications in different conditions.
