Dynamic model of planetary gear set is developed. This model allows to calculate dynamic transmission error, dynamic stresses in gears of planetary set. Based on the developed dynamic model, recommendations to reduce dynamic loads in planetary gearbox were developed. It is shown that effective way to reduce dynamic loads in planetary gearboxes is to use gears with a high contact ratio.
