Diagnostics and reconstruction of bearing units

Abstract

This paper presents new research results aimed at ensuring reliability and durability of equipment due to its diagnostics including monitoring and recording parameters changes of bearing units technical conditions determined before the moment of equipment shutdown, dismantling and fault detection of units as well as development of new methods for their restoration. As a method of operability recovery of unique bearing units a progressive approach is offered based on use of composite material 'Multimetal Stahl 1018'. A new field of application of composite material 'Multimetal Stahl 1018' to create temporary bearing sliding support instead of failed unique design construction with rolling bearings is described. Successful operation of majority of industrial equipment units restored using composite materials evidences broad prospects for solving various repair tasks mechanics of repair industries face including protection of foundations from destruction during vibration loads.
