在差速器中,这些都是指减速比。
Gears of first stage are changeable so that the operator can change the gear ratio based on current field condition.第一级传动齿可变,驾驶员可根据电流与磁场情况来改变齿数比。
Then we conclude the five-bar's classification and the gear ratio and phase Angle in each classification to be full rotatability.然后详细的讨论了五杆机构在每一种分类情况下机构中存在双曲柄时机构的传动比及相位角的范围。
