Purpose. To check meeting the requirements of Standards for experimental specimens of traction gear boxes for electric trains of series ER2, ER9 with housings of welded construction by Kiev Electric Wagon Repair Works (KEVRZ). Methodology. To reach the objective in hand, performing the work, some computational models for theoretical determination of the stress levels in the reduction-gear housing of welded construction by simulating the loading conditions that can take place during the operation have been developed and the stresses at different points of the reduction-gear housing as well as the levels of vertical accelerations of the reduction-gear housing and loading of the unit of connecting the housing to the bodies frame have been experimentally evaluated. Findings. On the basis of analysis of the calculation results obtained meeting the requirements of Standards for traction reduction gears with the housings of welded construction by KEVRZ has been found. Originality. Based on the experimental and theoretical investigations, the scientific support of works on developing and putting into operation the renovated traction reduction gears for electric trains of series ER2, ER9 has been completed. Practical value. A technical solution with the measures to be fulfilled in operation of electric trains of the mentioned series with traction reduction-gear housings of welded construction by KEVRZ has been developed and given to experts of Ukrzaliznytsia to introduce the proposed measures during repairs.
