摘　　要：基于船用齿轮箱相关技术条件,考虑轴、轴承、箱体等变形及传动过程中的相互影响,提出以联轴器跳动值作为船用齿轮箱刚度评价的新方法。采用有限元法建立船用齿轮箱的刚度分析耦合模型,得到箱体与轴变形、轴承与轴承座刚度等参数,计算出齿轮箱联轴器跳动值;结合理论分析设计刚度测试实验,根据实验结果与理论分析相对比,误差在11%以内,且满足技术要求,说明以联轴器跳动值作为船用齿轮箱刚度评价的新方法是有效的。Based on correlate technique conditions of marine gearbox,it is proposed to take run-out value of input and output couplings as the stiffness evaluation of marine gearbox. This new method is put forth on rated load by considering the deformation interrelationship in transmission of some main parts, such as shaft, bearing,gear and box. Finite element analysis of strength and deformation of marine gearbox under forward and backward conditions are conducted. Parameters, such as box and axis deformation, bearing and shaft block stiffness, etc. are obtained and run-out value of input and output couplings is calculated. Experiments are carried out at gear drive test bench to verify the reliable of stiffness evaluation method. Compared with the experimental results, the error is in 11%~,which shows the proposed stiffness method is valid.
