✦ Synopsis

by some to reduce the life of a bearing to as liffle as 48th but Mr Scott said that modern emulsions were a8 good a8 mineral oils and sometimes better.

But exactly what a modern emulsion is, nobody said.

Diagnosis of incipient failure

Four main method8 of diagnosis were mentioned Mr D. G.

Hjertsen valued noise analysis and vibration analysis for rolling-contact bearings, as a mean8 of predicting failure and of detecting bad fitting. The noise intensity al80 relates to the diametric clearance within the bearing. Two other delegates reported neutron activation analysis of oil samples a8 being accurate to 0.2 parts per million and the spectrographic analysis of oils. In all techniques, the important thing was to correlate the reading8 with bearing failures and to look for change8 in rate of wear and for a pattern of failure.
