Technical Description
The journal bearing apparatus for
investigating the distribution of pressure in slide bearings illustrates
the principle of hydrodynamic lubrication. The distribution of pressure
and the carrying capacity can be determined on a sliding bearing model
at different bearing loads and speeds. The sliding bearing consists of a
bearing journal driven by an electrical motor and the freely moving
bearing housing. The bearing is loaded with different, interchangeable
weights. In order to view the shifting of the bearing journal in
operation as clearly as possible, the model has a large gap and a
transparent housing. Both the radial and axial distribution of pressure
can be recorded in the bearing gap at 12 measuring points around its
perimeter and four along the length. The measurements are shown by means
of 16 tube manometers mounted on a board. The system is mounted on a
rolling support and is well suited for demonstration as well as for use
in laboratory experiments.
