10、ft 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 and cold-drawing or by machining-finishing with diametes in increment

11、s of 6mm or less.實心軸可利用直接購買的直徑最大可達到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 flanged to the spindle shaft,while conventional or normal spindles are mostly gear or belt driven.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動。4.The cold rolled shafts are stron

12、ger 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，但是會存在較大的殘余應力。在對傳動軸進行機加工特別是車槽或加工鍵槽時，殘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 ref

13、erred 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，其上下左右側面互相平行。6.Rigid couplings should be used only when the alignment of the two shafts can be maintained very accurately,not only at the time of installation but also during operation of the machines.剛

14、性聯(lián)軸器只能用于連接在安裝和使用過程中對中性都有很好的兩根傳動軸。第六單元1.The main functions of lubricant system can not only cut down friction by coating moving parts with oil,but also produces a seal between the piston rings and the cylinder walls.潤滑系統(tǒng)不但可以通過在運動零件上涂油而減小摩擦，還可以通過在活塞環(huán)和氣缸壁之間儲存機油，產生密封的作用。2.The basic job of the suspension

15、 sysrem is to absorb the shocks caused by irregular road surfaces that would otherwise be transmitted to the vehicle and its occupants,thus helping to keep the vehicle on a controplled and level coures,regardless of road conditions.懸掛系統(tǒng)的基本功能是吸收不平坦路面引起的震動，否則該震動會被傳遞給車輛和乘坐人員。因此，懸掛系統(tǒng)有助于在各種路況下保持車輛可控并水平行駛

16、。第九單元1：In summation,as the production volume increases,the combination of productivity gains and the ability to spread the setup cost over many parts makes CNC machining the obvious choice.總的來說，由于生產量增加，生產率提高，配置成本分散到眾多部件上，數(shù)控加工成為顯而易見的選擇。2：The pallet is a removable table on which the workpiece is mount
