10、f retaining rings ,thrust bearings,grooves and steps in the shaft are used to take up axial loads and locate the rotating elements.傳動軸一般用滾動或滑動軸承支承， 用推力軸承、 鍵槽、 軸肩和定位環(huán)等為旋轉(zhuǎn)零部件定位 并且承受軸向載荷。2.A solid shaft is obtainable commercially in round bar stock up to 15cm in diameter.It is produced by hot -drwing a

11、nd cold -drawing or by machining -finishing with diametes in increments of 6mm or less.實心軸可利用直接購置的直徑最大可到達 15cm 的棒料通過熱拔，冷拔或機加工制成，軸的 直徑可由 6mm 或更小開始遞增。3. High speed spindles are designed with the spindle motor flangedto the spindle shaft,whileconventional or normal spindles are mostly gear or belt driv

12、en.高速主軸一般通過法蘭與主軸電動機連接，而普通主軸常常通過齒輪或傳動帶驅(qū)動。4. The cold rolled shafts are stronger than hot rolled shafts but with higher residual stresses.The residual stesses may cause distortion of the shaft when it is machined,especially when slots or key ways are cut.冷軋加工的傳動軸強度比熱軋加工的高， 但是會存在較大的剩余應力。 在對傳動軸進行機加 工特別是

13、車槽或加工鍵槽時，剩余應力的存在會導致軸發(fā)生撓曲變形。5. Both the squarte and the rectangular keys are referred to as parsllel keys because the top,bottom and the sides of the keys are parallel.方鍵和矩形鍵都是平鍵，其上下左右側(cè)面互相平行。6.
