It is proved correct and practical to choose the meshing area as the objective function in the fuzzy optical design of ZC1 worm transmission in escalator.
实践证明，在自动扶梯zc1蜗杆传动模糊优化设计中，选择啮合面积为目标函数是正确的、可行的。
The reason of such fine transmission form can not be used widely of two packs of worm pairs lie in their design parameter more, complicated processing technology and very sensitive to the error.
平面二次包络环面蜗杆副这种优良的传动形式一直不能得到广泛应用的原因就在于其设计参数多、加工工艺复杂，并且对误差很敏感。
The results indicated that the new design declined center space 20% and sharply shorten worm transmission accessory stocking cycle, which greatly saved raw and processed materials and production cost.
计算结果表明：新的设计方案使蜗杆传动的中心距下降了20%，能缩短蜗杆传动零部件的采购周期，从而节省大量原材料和生产成本。
