Journal Bearing Tester (Basic)

The Ducom Journal Bearing Tester (Basic) is designed to demonstrate and study pressure distribution behavior of lubricants in journal bearings.

The system consists of a vertically mounted journal driven by a variable speed motor. The load is applied radially to the bearing with a loaded lever. Journal bearing assembly is immersed in lubricant. An electronic sensor measures the oil film pressure. The angular position of the pressure senor with respect to the load line is varied and pressure is recorded.

Pressure is plotted as a function of angular position of Cartesian or polar form to demonstrate the pressure distribution. Test variables are journal speed, radial load and lubricant viscosity.
