| 摘 要： | 齿轮的鼓形修整可以大大减小因齿向啮合误差而引起的局部应力集中。但如果鼓形量取得过大,齿面会产生很高的接触应力;如果取得太小别又不足以补偿齿向啮合误差,同样引起载荷集中。鼓形修整量的选择一般是按经验估值。本文讨论了一种通过理论计算来确定鼓形修整量的方法。鼓形齿轮各齿对接触栽荷的分布情况可以看作为一些几何参数相同的半椭球或部分半椭球分布。这些半椭球或部分半椭球分布载荷的总和等于一对齿轮传动时的总栽荷。按这一假定导出了计算最大接触应力的一组公式。考虑存在不同齿向啮合误差的接触应力的计算,将十分有助于选出最适当的鼓形修整量。

| Abstract: | The yarn is twisted by ring and traveller in ring frame. The fluctuation of twisting and winding speed, caused by the continuous changes of the ring rail position, the winding diameter and the balloon shape during the ascending and descending motion of the ringrail, is reflected directly in the variation of cop twist density, which affects the winding performance and the product quality. Therefore, in this paper, the relationship among all the main relevant twisting and winding parameters and the resulting twist unevenness is analysed. |
