Journal Bearing Test Rig

The journal bearing test rig for investigating the distribution of pressure in slide bearings the principal of hydrodynamic lubrication. The distribution of pressure & the carrying capacity can be determined on a sliding bearing model at different bearing loads & speeds.

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 & viscosity in relation to oil temperature
