Therefore, it is necessary and feasible to explore the effect of gear rotational speed on the gear contact fatigue life.

所以，探讨齿轮转速对齿轮传动接触疲劳寿命影响是必要且可行的。

An epicyclic gear system (34) is attached to the output shaft (33) of the motor, to produce an output of reduced rotational speed.

行星齿轮系统(34)与马达的输出轴(33)相连，以产生转速降低的输出。

Based on this, the sensitivity issue of the rotational speed and torque of the differential gear train is analyzed in detail by the experimental study.

在此基础上，对差动轮系的转速和转矩灵敏度问题进行了详细的分析，并通过试验研究加以分析。
