双万向联轴节恒定传动比条件推广及应用

本文讨论了双万向联轴节具有瞬时恒定传动比需要的条法。证明了当中间轴的两个叉面不在同一个平面内时,仍有一组瞬时传动比为1的双万向联轴节存在。这种联轴节的输入轴与输出轴成空间交错轴关系。这种机构的存在使双万向联轴节瞬时传动比为1所要求的条法得以扩展,而且这种机构还可用于传递空间交错轴之间的运动,且瞬时传动比为1。

EXPANDING OF CONDITION OF DOUBLE UNIVERSAL COUPLINGS TO TRANSMIT MOVEMENT IN CONSTANT ANGULAR VELOCITY RATIO AND APPLICATION

The paper discussed the condition double universal couplings need in order to transmit movement between the two shafts that parallel or intersect in constant angular velocity ratio during one revolution, Proved there exist a group of double universal coplings which can transmit movement in constant angular velocity ratio under circumstance that the two v-shapcd forks don't lie in a same plane, And so expanded the condition double universal couplings need to transmft movement in constant velocltyratio. The input shaft and output shaft of this kind of double universal couplings are non-parallel, non-intersecting. this kind of mechanism can be used to transmit morement between non-parallel, Non-intersecting shafts in constant angular velocity ratio instead of crossed helicial gearing in some place.
