It is tried to use the S 2 type of gear rolling tester at the high rotational speed where the meshing frequency is about 1/2-2 times as large as the natural frequency of a pair of gears. This trial is based on the simplified measuring principle. As a result, it is found that the gear rolling tester can measure the dynamic transmission error of gears with the accuracy enough for practical use. Next, the dynamic transmission error of hobbed gears which have large profile errors is measured under light load condition, and the vibration of gears is studied experimentally. As a result, the following phenomena are observed : the large and irregular vibration skipping several teeth occurs near the resonance speed of gears, and it does not decrease even at the higher rotational speed than the resonance one, the period, where the teeth of gears separate and do not mesh during rotation, reaches 70%-80% of the total rotational period and also do not decrease at the higher rotational speed than the resonance one.
