Application
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
