对数型铁路轴承圆锥滚子的试制

Trial-producing logarithmic tapered roller of railway bearing

为了提高铁路轴承圆锥滚子的凸度值,采取改变原加工中接触角的方法,使圆锥滚子的凸度值达到工艺要求。

For the sake of improving the camber of tapered roller of railway bearing,a method of changing contact angular was adopted during producing,it also make the camber meet all requirements for technology.
