Hydrodynamic Bearing Apparatus

Product Description

Hydrodynamic Bearing Apparatus Technical Description of Hydrodynamic Bearing Apparatus 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.
