1.
Gear A, at the end of the drive shaft, and gear B, on the countershaft, are in constant mesh.
齿轮A位于驱动轴的末端，齿轮B在副传动轴上，它们恒定啮合。
2.
countershaft (excl. motor vehicle and aircraft parts which are not internal parts of engines)
副传动轴（非发动机内部零件的机动车辆和航空器的零件除外）
3.
Hence, the countershaft and all its rigidly connected gears are in motion whenever the drive shaft revolves.
因此，当驱动轴旋转时，副传动轴及与其刚性连接的齿轮都处于运动中。
4.
When none of the sliding gears is in mesh with its countershaft gear, the gears are said to be in“ neutral.
如果没有变速齿轮组与副传动轴上的齿轮啮合，这时，就叫做空挡。
