Experimental investigation of a highly-loaded half-journal bearing
Abstract
Dataset from experimental rig is presented for a half-journal bearing operating under highly loaded, well-controlled hydrodynamic lubrication conditions relevant to turbomachinery. The apparatus combines pressure measurement in the film, distributed temperature measurement in the shaft and bush, and ultrasonic film thickness measurements that map the circumferential film height profile across the lubrication region. Experiments are reported for normal loads of 5–20 kN and shaft speeds of 1000–4000 rpm with controlled oil supply conditions.
