　　烟草收获机的后轮传动采用链传动，其张紧机构的可靠性直接影响到烟草收获机的整机性能。为此，对烟草收获机的竖直链张紧机构中的鼠牙条，进行了传统分析，在 Solidworks 中建立了其三维模型，并将该模型导入ANSYS有限元分析软件建立有限元模型。通过静力结构分析得到了鼠牙条的应力大小与分布情况，找到了该机构的薄弱环节，而后将改进的两种鼠牙条与原鼠牙条进行比较，找到了较好牙形的鼠牙条。

Tobacco harvester's rear transmission is adopted chain-drive, the reliability of whose tensioning institution di-rectly influences the performance of tobacco harvester .Aiming at gear rack of vertical chain of tobacco harvester , first I carried on the traditional analysis, then established its 3D-model in Solidworks, and then led the model into Ansys to build finite element model , then I got the size and distribution of stress of gear rack and found the weak links of the insti-tution through analyzing the static structure .Compared the improved and original gear rack , I found a better tooth shape.
