船舰用齿轮箱轴承孔的中心位移及轴线偏移量计算

The Calculation of Center Displacement and Axis Deviation of Marine Gear Box Bearing Hole

以某舰用齿轮箱为例,用有限元法计算出轴孔周边各离散点的位移;然后确定变形后的齿轮箱体轴孔中心位移量,最后确定出变形后的箱体主动轮轴线和从动轮轴线的夹角。

Taking a certain marine gear box as an example, this paper calculated the displacement of every discrete point on a bearing hole periphery by use of finite element method and then determined the center displacement of gear box bearing hole following a distortion of the gear box and also the included angle between the post-deformation gear box body driving wheel axis and driven wheel axis.
