Michell Tilting Pad Bearing Apparatus

The unit is designed to provide visual demonstration and measurement of longitudinal and transverse pressure distribution over Michell Thrust Bearing. Students can vary speed, gap and viscosity of oil. It gives visual demonstration of cavitaion. The unit consists of a belt moving on two identical pulleys driven by variable speed d.c.motor. The belt passes through a oil tank and carries oil film along with. This oil passes through tilting pads and develops pressure, which is measured by manometer through pressure tapings on tilting pad. Different types of pads can be used.

Specifications:

• Drive Motor - 0.5 HP, 1,500 RPM, variable speed D.C.Motor with speed controller.
• Tilting Pad -
  1. Convergent Type - Rectangle
  2. Convergent Divergent Type - Rectangular.
• Multitube Manometer.
• Manometer for cavitation demonstration.
• Oil Tank - 0.5 X 0.2 X 0.2 m approx.
• Loading arrangement on pads.

Experimentation :

1. Determination of pressure development.
2. Plotting pressure Variation curve in longitudinal & Transverse direction of a pad for various speeds.
3. Demonstration of cavitation phenomenon.

Service Required :

• 230 V.,A.C. stabilised power supply.
