大模数齿轮齿条试验装备轴承座刚度优化研究

Stiffness optimization research of bearing block for large module gear-rack test equipment

采用有限元法,通过对不同结构型式的轴承座的刚度、强度进行对比分析,给出了高可靠性、大刚度轴承座结构;结合试验台特点,对轴承座组进行整体设计,采用平板通过螺钉和销钉连接将四个轴承座组合成一体,通过提高整体结构刚度来最大程度地减小单个轴承座变形对试验结果的影响,经过分析验证达到了预期的效果。

Using the finite element method,through a comparative analysis on stiffness and strength of different structure types of bearing blocks,the high reliability and large stiffness bearing block has been obtained. Combined with the characteristics of test equipment,the four bearing blocks are combined into one group by screws and pins,to minimize the effect on test results of the deformation for every single bearing block. After analysis and validation,the desired results are achieved.
