非线性方程法计算链传动中心距

给出了计算链传动中心距的非线性方程法，当链传动的链条总长是链节的偶数倍时，由该方法计算出的链传动中心距最大值和最小值几乎和Winklhofer方法的计算值相同，而其他计算方法（如渐开线法）只能近似计算链传动中心距，不能计算链传动中心的最大值和最大值，非线性方程法可用于参数是任何值的链传动，可计算出链轮在任何位置时的链传动中心距，且可计算链传动中调整的重要链传动，或在同一中心距上有多挂链条的平行传动，具有重要的意义。

Determination of Center Distance of a Roller Chain Drive

A series of nonlinear equations are used to calculate the center distance of a roller chain drive. The maximum and minimum distances are found to be almost the same as by the Winklhofer method which applies only when the length of chain is an even number of chain pitches. Other methods can only give approximate values. The presented method can be used in any roller chain drive where the two sides of the chain are straight. The method is significant for a roller chain drive with fixed center distance.
