Abstract

What is ISO 31657 ‑ 1 about?

ISO 31657 ‑ 1 is the first part of a series of documents on multi-lobed and tilting pad journal bearings. ISO 31657 ‑ 1 specifies the general principles, assumptions and preconditions for the calculation of multi-lobed and tilting-pad journal bearings using an easy-to-use calculation procedure based on numerous simplifying assumptions. For a reliable evaluation of the results of this calculation method, it is indispensable to consider the physical implications of these assumptions as well as practical experiences for instance from temperature measurements carried out on real machinery under typical operating conditions. Applied in this sense, this document presents a simple way to predict the approximate performance of plain journal bearings for those unable to access more complex and accurate calculation techniques. The calculation method serves for the design and optimisation of plain bearings, for example, in turbines, compressors, generators, electric motors, gears and pumps. It is restricted to steady-state operation, i.e. in continuous operating states the load according to size and direction and the ang...
