摘要

The present research study is carried out to study the performance characteristics of two noncircular jour-nal bearing profiles. Experiments are conducted on a phosphorous bronze hydrodynamic journal bearing test rig to measure the circumferential oil film pres-sure as well as on the temperature profile at different radial loads and constant rotational speeds to mea-sure bearing performance characteristics, such as oil flow rate, maximum temperature, and pressure. Re-sults reported that noncircular bearings can with-stand higher load and minimum power losses than circular bearings. Also, with an increase in the radial load, the oil film pressure and temperature also in-creased. However, a reduction in negative pressure gradient is reported along the circumference of the lobe resulting in lesser thermal degradation in com-parison with the cylindrical bearing.
