INTRODUCTION
“EEE†Journal Bearing Apparatus consists of a plain steel shaft encased in a bearing and directly driven by a small electric motor. The bearing is freely supported on the shaft and sealed at the motor end. The motor speed is precisely controlled and adjusted by specially designed control unit and can be run in both directions.
The bearing contains twelve equispaced
pressure tapings around its circumference and four additional ones along its topside and one vertical radial plane. All are connected by light and flexible plastic tubes to the rear manometer panel so that pressure head of oil at all sixteen points can be clearly observed at all times. Oil is supplied to a law pressure region at both ends of the bearings by an adjustable reservoir fitted at the side of the rear panel. The bearing can be loaded by attaching various weights to the arms supported beneath it. A table is conveniently provided at front of the apparatus.
FEATURES
1. Acrylic Bearing Housing allows clear observation of the oil film at all ties
2. Pressure profiles along and around the bearing continuously monitored on large manometer panel.
3. Theoretical pressure profile (Sommerfeld Analysis) can be carried out and compared with practical
results.
4. Wide range of speed and loads possible.
5. Ideal for group studies and demonstrations.
6. DC motor is used with speed control unit.
6. Digital pressure indicator- 1no. for pressure measurement for each tapping
RANGE OF EXPERIMENTS
1. Simple Demonstrations
2. Observation of the pressure profile at the various conditions of load and speed
EXPERIMENTAL INVESTIGATION
3. After noting the pressure profile for any chosen conditions, the following analysis may be
conducted.
4. Plotting the Cartesian and polar pressure curves.
5. Plotting the theoretical Sommerfeld curves. -k sin (2+ncos)
