Measurement of Wear in Radial Journal Bearings
In this article, the measurement of wear i n radial journal bearings is discussed, where a distinction is made between stationa y and non-stationa y contact conditions. Starting with Holm/ArchardS wear law, equations are derived for the calculation of the specific wear rate k of the bearing material as afunction of the wear depth d, measured after an experiment or a period of use i n practice. ...

متن کاملtaylor-couette flow instabilities in journal bearings
in industry, flow instabilities are important in journal bearings at high rotational speeds. for inviscid flows between two rotating coaxial cylinders, an instability criterion was introduced by taylor-couette. however, viscosity may play as stabilizer or destabilize in such flows. in this work, stability theories were reviewed for two coaxial rotating cylinders. then, flow instability patterns...
متن کاملElectrostatic wear monitoring of rolling element bearings
Research and development work at the University of Southampton using an electrostatic condition monitoring system developed by Smiths Aerospace Information Systems has shown that electrostatic charge signals can be used to detect the onset of wear in lubricated tribo-contacts. Preliminary investigations have already demonstrated the viability of this system when tested on a laboratory-based pin...
متن کاملDesign Of Journal Bearings In Reciprocating Compressors
Journal bearings in hermetic reciprocating compressors are analyzed experimentally as well as numerically. The motor current and the load applied to the bearing are measured to obtain the performance curve of the journal bearing, from which the critical Sommerfeld number is derived. In the numerical analysis, the Reynolds equation and equilibrium equations of the journal center are solved simul...
