The function of the control arm is preventing rotation of the adjustment mechanism relative to the actuator 控制臂的功能是在于阻止调整装置相对传动装置做旋转运动
Transmission of rotary motions ; types of connection to gears , intermediate gears , flexible drive shafts and equipment 旋转运动的传动装置.第1部分:连接齿轮中间齿轮挠
They can be pressed into the housing bore directly . linear ball bearings are only suitable for linear motion 直线运动球轴承只能用于直线运动，不能作为旋转运动部件的支承。
Input a revolution to the handle to drive the helical gear set to rotate another rotation system 手把输入旋转运动于转轮，转动小齿轮和大齿轮。由小齿轮转动另一组的转动系统。
The handle inputs rotation upon the wheel , then transmitted to another shaft by the belt transmission mechanism 加上皮带传动机构，手把输入旋转运动于转轮，用皮带传输转动另一个轴。
The resulting standing wave is a swirling motions such as might result if we swirled water in a round - bottomed cup 所产生的驻波是一种旋转运动，它是在我们转动圆底杯中的水时会产生的现象。
In motions of rotation angular momentum appears in much the same way as linear momentum appears in motion of translation 在旋转运动中的角动量产生的方式与平移运动中的线动量的产生是基本相似的。
The crankshaft , in conjunction with the connecting rod , converts the reciprocating motion of the piston to the rotary motion needed to drive the vehicle 曲轴，和连杆一起，把活塞的往复运动转化为驾驶车辆需要的旋转运动。
Cam mechanism can transfer the revolvement of cam to the motion of follower by rule , so it has been be very widely applied in various machinary 凸轮机构能将凸轮的旋转运动变成从动件有规律的运动，被广泛应用于各类机械中。
It swirls , as circular motion in air masses is the response to conflicting forces , as seen in the circular motion of tornadoes and hurricanes 它形成旋风，因为旋转运动是空气在碰到阻力时的反应，就象在刮龙卷风和飓风时看到的那样。
