ABSTRACT:
A machine for testing and comparing chains and sprokets of various geometries and materials comprising four sprockets and two chains and having a pneumatic cylinder for loading one chain against another. A motor which drives a rotatable fixed shaft which is mounted in two pillow block bearings. This shaft contains two sprockets. A second rotatable shaft is journalized in two pillow blocks mounted on a movable platform. Means are provided for applying a predetermined load through the movable platform to the second shaft and means are also provided for measuring the total cycle to chain-sprocket system failure. Means are also provided for determining chain load, for measuring chain and sprocket temperatures, for lubrication of the chains and sprockets, for cooling the test chamber, and for automatic machine shut off at failure.
