TM 280: Journal Bearing Apparatus

Print Ask to this Articlel

Journal Bearing Apparatus

Journal Bearing Apparatus

Product Details


Technical Description 
 
The journal bearing apparatus for investigating the distribution of pressure in slide bearings TM 280 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.

Learning Objectives / Experiments
 
- Relocation of the shaft journals in relation to speed
- Pressure distribution in the bearing with constant
  load and at various speeds
- Critical speed in relation to load
- Critical speed and viscosity in relation to oil
  temperature
