To reduce the size of reduction gears where big power is transmitted through crossed shafts, it is necessary to increase rotational speed and decrease the transmitted torque and load. To know dynamic behaviour of high speed bevel gears, the experiments were carried out and tooth root stress and temperature were measured. Also a spiral bevel gear set analysis has been developed that makes use of mesh stiffness calculations based on finite-element methods. The analysis enables the calculation of dynamic loads. And then, the following results were obtained. (1) A power absorbing gear testing machine (960 kW) could be operated up to high pitch line velocity (〜110 m/s) and it is found that dynamic loads is nine times as much as static loads under the condition of 110 m/s. (2) Analytical results of dynamic load agreed with the experimental results. It was confirmed that the analytical method has practical accuracy and usefulness.
