摘　　要：针对当前现有联合收割机变速箱存在的问题,提出YM60型无级变速箱。重点理论计算及有限元分析YM60型无级变速箱割台轴,获得割台轴六阶固有激振频率、变形和应力分布,为提高割台轴的使用寿命及安全可靠性及后期变速箱整机的优化设计提供一定的理论依据。Aiming at the existing problems of continuously variable transmission on combine harvester, YM60 continuously variable transmission was presented. Based on the theoretical calculation and the finite element analysis of header shaft, the distributions of first 6 orders＇ natural vibration frequency, deformation, and equivalent stress were obtained. This study provides a theoretical basis for improving the service life and safety reliability of header shaft, and the optimal design of continuously variable transmission.
