Determining the Roughness of Contact Surfaces of the Rolling Bearings by the Method of Shock Pulses
One of the most effective methods for bearing diagnostics is the method of shock pulses. The fixed pulse levels for specific type of bearings and a specific working position are in corresponds with the parameters, characterizing the resource of the bearing. Roughness is one of those parameters. Adaptation and application of that method to slow-revolutionary large rolling bearings of wheel excavators, spreaders and belt conveyers is commented in the paper. A diagnostic system for control directed towards repair is worked out as a result of the adaptation of standard diagnostic approach for application to non-standard (from a vibrodiagnostics point of view) bearing nodes of mechanization at the bulgarian open-pit mine “Maritza-East Mine” Ltd. In Bulgaria.
