According to the fact that a universal coupling was constantly broken in a mine, the paper gave a common formula of the drive rate of a bi universal coupling on the basis of other people s work, and thus a universal conclusion was obtained that the drive rate can be kept constan
本文根据某矿山万向节频繁扭断事故的实例 ,在文献 [1]、 [2 ]的基础上 ,导出了双万向联轴节传动比的普遍公式 ,并得出了保持传动比恒定的普遍性结论。
For eliminate redundant stress in spring unit brought by continuously variation of strain,in wind spring device,the adopt spiral output wheel with continuously variant radii was used and the variation of moment can be canceled out by variation of radii,the approximate constant output force can be obtained.
为消除弹簧装置中应力随应变不断变化而产生的多余应力 ,在卷簧结构中 ,采用螺旋变径输出轮 ,用半径的变化抵消力矩的变化 ,获得近似恒定的输出力 。
