The pressure and temperature distributions are measured in a full journal bearing. The journal bearing has 219.94m dia., length-to-diameter ratio of L/D = 0.8 and clearance ratio of 0.004.
The effects of journal speed and bearing load on pressure distributions and the temperatures of bearing surface are discussed. Journal has a built-in transducer for measuring pressure distributions in the mid plane of the bearing. The journal speed is varied from 300rpm to 2500rpm and the bearing load from 300N to 5900N.
As the load is increased under constant speed, the location maximum pressure moved to the location of minimum film thickness, and maximum pressure and absolute value of minimum pressure are increased. The temperature distribution in the vicinity of oil inlet show that the heated lubricant's carry-over exist around the oil inlet. The maximum bearing temperature of bearing surface is increased with the increased of bearing load.
