description: The given work is devoted to determining the necessary design checks for the gearing of the locomotive traction gearbox, taking into account the requirements of GOST 21354. The work set the following goals: 1. Carrying out the geometric calculation of gearing. 2. Selection of materials and methods of heat treatment. 3. Design test for fatigue and strength, taking into account the gear interference fit on the shafts. 4. Selection and calculation of tooth modifications. 5. Determination of the required characteristics of the lubricant. Calculations are performed using analytical methods, finite element methods, and finite difference methods. The gearing calculations take into account the misalignment of the teeth in operation under the influence of shaft bends and bearing gaps, as well as taking into account the rigidity of the housing. The total stresses occurring on the lateral surface of the teeth and in the area of the tooth foot are calculated. The total stresses occur under the action of the interference fit and the transmitted torque. As a result of the calculations, the most suitable initial gearing profile was selected and the modifications of the gear teeth were selected. The paper shows the necessary calculations and their sequence. The results of this work can be used in the design and calculation of gearboxes in different areas of mechanical engineering.
