Hydrodynamic Bearing Apparatus- Engineering Lab Training Systems.
Technical Description
The behaviour of a classical journal
bearing with hydrodynamic lubrication can be investigated with the
apparatus . The experimental capability ranges from the measurement of
friction torque under load, to determine the pressure distribution in a
journal bearing, to plot a locus curve of a journal and to determine the
bearing attitude for different conditions of load and speed. The radial
load of max. 500N is adjusted manually with a hand wheel. The drive is
an asynchronous motor with frequency converter. All variables (speed,
load, friction torque, oil supply pressure, oil peak pressure, oil
temperature, X-displacement, Y-displacement) are indicated on 4-digit
displays. Five different journals are used to examine bearing clearance.
X and Y positions are measured using inductive displacement sensors.
The friction torque is measured by means of a lever arm equipped with an
electronic force sensor.
