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
