Assembling quality diagnostics

Automatic system for condition assessment of electric-driven rolling stock assemblies. Including wheel-motor units and wheel pairs.

The quality of production and repair of wheel-motor units and wheel pairs was always a priority, since the failures of such equipment are more hazardous over the consequences they can cause. The failures of rolling stock units of railway transport reduce the technical readiness coefficient, which leads to high operating costs in the sector.

The main reason of such situation is the high wear of a rolling stock and also lack of control of units` condition during their manufacture, repair and operation. It is possible to significantly reduce the number of unscheduled repairs and, as a result, the operating costs, by applying the quality diagnostic systems at plants and depots, control and monitoring systems of assemblies of rolling stock in the process of maintenance and current repair.

The system should allow to assess the quality of manufacture and/ or repair of wheel motor units and wheel reduction gear units to detect the hidden defects of bearings, gearbox gears, the lubrication quality and defects of assemblies’ balancing, alignment and fastening.

The various systems for diagnostics of the wheel-motor unit (WMU) of EMU-trains, which are notable not only for design features, but for a methodology, a diagnostic process, methods for defects determining, etc. are introduced and operated in Russian locomotive depots. The disadvantage of these systems is the low degree of the diagnostic process automation, that increases its duration, reduces the reliability and throughput of the systems. The automatic system for vibroacoustic diagnostics of WMU – COMPACS®-EXPRESS is described in the present article.
