transmission shifting mechanism

基本解释

The other speed shifting mechanism is a shaft of the driven gear that is provided with a tooth driving wheel that puts the roll shaft in motion through transmission.
另一个动力辊变速机构是：在所述从动齿轮介轴上还装有齿系传动轮，该齿系传动轮将运动副传递给上辊轴。

The speed shifting mechanism is a two-stage or more than two-stage speed shifting mechanism formed by that at least two pairs of straight gears are made a transmission fit.
所述变速机构是由至少两对直齿轮传动配合构成的两级或两级以上的变速机构。
