 Full text | Abstract: The subject of this paper is the theoretical investigation of low-speed, mechanically and thermally heavy loaded journal bearings of calendaring and similar type machines operating under identical conditions. A heated press cylinder had hollowed journals of large diameters with a heating system inside. The temperature of the heated cylinders even reaches 300 °C and the temperature of the journal reaches about 250 °C. These large overall dimensions, journal bearings, heavy loaded mechanically and thermally, require a very precise analytical investigation. Application of the developed program of calculations of heavy loaded, pressurized or not journal bearings should allow the durable and reliable design of bearings to be obtained. |
