One of the reasons for unforced train delays happen during the operation of 2ES6 freight electric locomotives is sliding down, gear cuts from the cone shanks of heavy electric motor shafts. The situation becomes worse when mechanical defects occur in the joints after pressing. Solving the problem is impossible without improving the fit technology. To simulate an interference fit, a finite element shaft-gear model is developed. A static analysis is performed in Simulation module of Solidworks, which includes an analysis of the stress-strain state and determination of the safety margin of objects according to several destruction criteria. Theoretical positions in conical joints are presented, in particular, the conditions of non-moving and strength of the joint. Based on simulation results, the range of diametrical interference values is adjusted, which ensures a favorable margin of gear safety.
