Journal Bearing Friction Apparatus- Engineering Lab Training Systems

Technical Description The basic tribological phenomena of journal bearings can be investigated using this unit. The journal bearing to be investigated consists of a stainless steel bearing journal and the free-moving gunmetal bearing housing. A three-phase AC motor with a frequency converter for speed control serves as the drive. A lever with a sliding weight attached to it is connected to the bearing housing. This enables an external moment to be set corresponding to the friction moment generated in the bearing. Another lever, combined with a set of weights, applies the defined load to the bearing. It is possible to view the bearing journal and the lubrication gap through the transparent cover. Lubricant is supplied by a wick oiler that feeds oil to the shaft via two lubrication channels. A drip tray collects the oil that leaks out. The continuously adjustable speed, as well as the temeperature of the lubricant, is indicated digitally on the control unit. The well-structured instructional material outlines the fundamentals of the theory and provides a step-by-step guide through the experiments
