摘要

对复合行星齿轮技术的特点作简要分析,并对其均载性能及均载系数的取值作了重点论述,给出了各啮合点最大相位差的计算方法和齿轮扭转角均载效果的计算方法。复合行星除太阳轮浮动外,内齿圈也有一定的浮动量;且其双联行星轮轴、内齿圈和主轴的连接段都会产生一定的扭转变形;通过算例说明,太阳轮和内齿轮的扭转变形量都比简单行星大的多,补偿制造偏差的能力要强的多;因此会有更低的均载系数。根据理论分析及已经取得的测试数据和实际设计的成功应用证明,风电齿轮设计中4个行星轮的复合行星的均载系数取1.10是适宜的。

Abstract

A brief analysis of the characteristic of the compound planetary gear technology is carried out,and the performance and the values of the mean load factor of the compound planetary are discussed. The calculation method of the maximum phase difference of the meshing points and the calculation method of mean load share performance for turning angle are put forward. In a compound planetary,there is a certain amount of floating in the inner gear ring,except for the float of the sun,the connecting segments of the twin planetary shaft,inner gear ring and the spindle produce certain torsional deformations. Through numerical examples illustrate that the torsional deformations of the sun and inner gear are more than simple planetary,the compensation manufacturing deviation caused by the uneven load ability is stronger,so there will be a lower mean load factor.According to theoretical analysis and test data which has been obtained and the successful application of actual design,it is appropriate to take 1. 10 as the planetary mean load factor of the compound planetary of four planets in the design of wind power gear.
