| Abstract: | The precise pressure distribution in the range of negative pressure of journal bearings was measured dynamically by a semiconductor pressure transducer fitted in the journal. Characteristics of the pressure distribution in the range of negative pressure were investigated and tensile stress was detected. A special apparatus was constructed to investigate the characteristics of tensile stress generation in lubricating oils. Currently available mineral oils of low viscosity, within a short standing time, were in a condition under which tensile stress could be generated. |
