n.對(duì)軸

Countershaft assembly uses tapered bearings to reduce end play and extend gear life. 中間軸組合使用錐形滾柱軸承以減少軸向間隙并延長齒輪使用壽命。

Hence, the countershaft and all its rigidly connected gears are in motion whenever the drive shaft revolves. 因此，當(dāng)驅(qū)動(dòng)軸旋轉(zhuǎn)時(shí)，副傳動(dòng)軸及與其剛性連接的齒輪都處于運(yùn)動(dòng)中。

Gear A , at the end of the drive shaft, and gear B, on the countershaft, are in constant mesh. 齒輪A位于驅(qū)動(dòng)軸的末端，齒輪B在副傳動(dòng)軸上，它們恒定嚙合。

When none of the sliding gears is in mesh with its countershaft gear, the gears are said to be in “neutral. 如果沒有變速齒輪組與副傳動(dòng)軸上的齒輪嚙合，這時(shí)，就叫做空擋。

Practice indicated that applying this process can realize mass production of automotive countershaft. 結(jié)果表明，采用這種工藝實(shí)現(xiàn)了汽車中間軸毛坯的大批量生產(chǎn)。
