Description and Specification for Lab Tenders
Astra Scientific Journal Bearing Apparatus.
The experimental 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.
