The article presents an analysis of methods of calculating the internal dynamic load of high-speed cylindrical gears (spur and helical ones) of external gearing, presented in the ISO, AGMA, DSTU ISO, BS ISO, DIN, GOST 21354-87, and a method developed by A.I. Petrusevich. Internal dynamic load is one of the main factors affecting the lifetime and vibration level of high-speed gears. The need to analyze the existing methods of calculation is caused by the need to choose a modern method of designing high-speed gears that meet the requirements of their usage in electromechanical power units of mobile machines with high-speed AC traction motors with permanent magnet excitation. The example of calculation of high-speed helical-toothed cylindrical gear of the reducer of the power unit of the electric vehicle is given.
