Journal Bearing With Hydrodynamic Lubrication

Product Description

Journal Bearing With Hydrodynamic Lubrication

In hydrodynamic bearings, the shaft and the bearing shell are separated from each other during operation by a supporting lubricating film. The pressure in the lubricating film in hydrodynamic journal bearings is generated by the relative motion between bearing shell and shaft. The position of the shaft in relation to the speed and the load is important for an analysis of the tribological process in the bearing shell of a journal bearing.

Learning Objectives And Experiments

1. Determine the coefficients of friction at various loads and speeds, compare with Stribeck curves
2. Influence of speed, bearing clearance and bearing load on the displacement of the shaft
3. Influence of speed, bearing clearance, bearing load and lubricant on the frictional moment
4. Locus of the shaft

Features

1. Frictional moment under different bearing clearances and loads
2. Pressure distribution in the journal bearing
3. Locus of the shaft under different loads and speeds
