Annotations languages:

The tasks of technical diagnostics of bearings, cooperant maintenance at high level of their efficiency and operating reliability are formulated. Ostensible, that diagnosing of bearings must be carried out on diagnostic signs and diagnostic parameters, to bearings information about the technical state of bearings and allowing to find out in them the hidden refusals, and also estimate a remaining technical resource. The methods of diagnostics are selected as evaluated by vibrations and noises, temperature condition, state and composition of butter, as most perspective. The selected methods of diagnostics fully correspond a modern level and prospects of its development.Formulas are offered for the estimation of time of diagnosing, remaining technical resource of bearings.
Keywords: technical diagnostics of bearings, tasks of diagnostics, diagnostic signs, diagnostic parameters, perspective methods of diagnostics, structurally-investigation chart of bearings
