塔吊回转机构中蜗杆传动优化设计

The OptimumDesign of The Worm Gearing for the Tower Crane Tutning Mechanism

采用随机方向法对塔吊回转机构的蜗杆传动进行了优化设计，并用图形表示了在优化搜索过程中各个设计变量之间的关系，设计结果表明，可以明显地节约有色金属用量。

This paper presents the optimum design with Pandom Direction Method for the worm gearing of turning mechanism of tower crane.The optimum answer by the computer compered with the regular design is that the nonferrous metal will be saved 38％ in thegearing of worm wheel .In this paper，it also showes the relations of the desigh changesin the course of optimum searching.
