摘　　要：对BFT型多柔传动现行计算公式进行了修正和补充。按新坐标系推导出该传动在有关结构对称布置条件下的双向传动的精确理论计算公式,在此基础上讨论了不均载系数,导出了均载时的计算公式,指出了BFT型多柔传动在双向传动时的均载性能是不相同的。为了保证良好的均载性能,必须进行优化设计。所给出的计算实例验证了计算公式的正确性。The current theoretical calculation formulas of the BFT type driving are amended and complemented in this paper. On the condition of symmetrical structure, we got the precise theoretical formulas under two-way transmission. Based on that, we discussed the unbalanced load coenfficient and derivated the formulas at balanced load, and concluded that balanced load performance of BFT type driving are different under two-way trnsmmission. To ensure well balanced load performance, optimization design should be done. The calculating examples have verified the corrctness of these formulas.
