Index Mechanism – Rob IvesIndex mechanism. Essential Mechanisms. An indexing mechanism or intermittent drive is a mechanism that turns a wheel or shaft a small amount then stops for a set amount of time the turns again repeating this process over and over as the drive handle is turned. Indexers are used for all sorts of things including digital displays when a sequential number can be displayed or in machines used to ...
