一下是一段外文设计,金山翻译太乱,请高手帮忙翻译个大概,现在急用,最后还会追加赏分.
In a testing machine for producing substantially linear vertical vibration the amplitude of which is continuously adjustable,the combination of a base; a motor supported on the base; a .movable table for supporting articles to be tested; a lower pair of parallel shafts journalled in said base; an upper pair of parallel shafts journalled in said table; a pair of eccentrics on each shaft;a substantially vertically extending link element undereach of the four corners of the table,each element having a journalled connection with an eccentric on one of the base-journalled shafts at one end of the element and a journalled connection with an eccentric on one of the table一ournalled shafts at the other end of the element;means for guiding the table in a substantially linear vertical path; means operably connected to said motor forrotating one of said shafts; a transmission housing; a pairof lower transmission shafts journalled an said housing,each lower transmission shaft .being coupled to one of said base一ournalled shafts; a pair of upper transmission shafts journalled in said housing,each upper transmission shaft having a flexible coupling connection to a respective one of said table一ournalled shafts; and transmission means including toothed rotating means secured on each of said transmission shafts and including means interconnecting said toothed rotating means for rotating them at the same speed,said transmission means also including differential means operably connecting said upper pair of transmission shafts to said lower pair of transmission shafts,and means for changing the orientation of said differential means far changing the phase relation between said upper and lower transmission shafts.
前面几楼都是翻译词典的，我需要的人工理顺一下。
