High frequency noise of gears is mainly from tooth error and base pitch, and low frequency noise from accumulated errors of toothspacing.
齿轮高频噪声产生的主要原因是齿形误差和基节偏差；低频噪声产生的主要原因是齿距积累误差。

The radial runout of tooth ring of the coniflex gear, which is an important test item, is an important factor influencing the accumulated error of toothspacing and the error of toothspacing.
直齿锥齿轮的齿圈径向跳动是重要的检验项目，是影响齿距累积误差和齿距误差的重要因素。

The faster the pulse repetition rate, the wider the spacing between the teeth, making each individual tooth easier to identify.
