以80 t塔式起重机的起升齿轮箱行星传动单元为研究对象，提出行星单元等强度设计思想。将轮齿啮合过程划分为若干区域并计算对应啮合线长度，根据啮合线长度对行星轮齿间载荷进行精确分配，在此基础上建立行星轮轮辐厚度与行星架销轴直径的协调优化关系，通过交互式计确定两者最佳几何尺寸以及强度匹配条件，从而实现行星传动单元的等强设计。研究结果表明：该方法可快速指导回转类齿轮箱行星单元等的强度设计，具有减重和降噪的实际意义。

With the planetary transmission unit of lifting gearbox of 80 t tower crane as a study object, the constant-strength design idea is proposed for the planetary unit.The wheel-gear meshing process is classified into various sections, with the length of corresponding action lines to be calculated, in order to accurately distribute the load between planetary wheel and gear according to the lengths of action line.The coordinated optimization relationship between the spoke thickness of planet wheel and diameter of hinge pin of planet carrier is built to determine the optimal physical dimension and strength matching condition through interactive design, hence to realize the constant strength design of planetary gear unit.The re-search result shows that the method can rapidly instruct constant strength design for rotary gearbox planetary unit, etc., providing actual significance of weight and noise reduction.
