摘　　要：针对某企业SDB-19型双速绞车使用过程中低速传动齿轮出现断齿的问题,借助有限元仿真分析软件,开展了齿轮断齿问题分析与改进研究工作。结果表明,齿根位置存在应力集中,最大弯曲应力值接近齿轮材料的屈服极限是齿轮出现断齿的主要原因。通过减小低速传动齿轮齿根过渡圆角半径的方法对其进行了优化,改进齿轮的应用,降低了运行维护费用,提高了双速绞车利用率。In view of the problem of low speed transmission gear broken in the process of using SDB-19 double speed winch in a certain enterprise,the analysis and improvement of gear broken tooth problem are carried out with the help of finite element simulation analysis software.The results show that the stress concentration exists in the tooth root position,and the maximum bending stress value is close to the yield limit of gear material,which is the main reason for gear tooth breakage.It is optimized by reducing the transition radius of gear root of low speed transmission,improving the application of gear,reducing the cost of operation and maintenance,improving the utilization ratio of double speed winch.
