摘要:
针对某大型传动装置中的一对斜齿轮,在Solidworks中建立了其装配模型,然后将其导入有限元分析软件ANSYS中进行接触应力分析,且将接触应力计算结果与传统接触应力计算结果进行比较;最后在ANSYS中针对该斜齿轮副的接触强度可靠性进行分析,结果表明:该斜齿轮副实际接触应力小于其许用接触应力,接触强度满足使用要求,但是其可靠度仅为83.6398% ,说明按传统的机械设计方法只进行安全系数的计算是不够的,还需要进行可靠性设计计算;此外,由各随机因素对极限状态函数的灵敏度可知,适当增大从动齿轮分度圆直径可有效提高斜齿轮副可靠度.
Abstract:
For a helical gear vice in a large transmission device,assembly model is created in Solidworks, andthen it is imported into the finite element analysis software ANSYS and stress analysis is contacted. Besides ,the contact stress calculation results and the traditional contact stress calculation results is compared;Finally ,the contact stress reliability in ANSYS is analyzed. The results show that : the helical gear vice actual contactstress is less than the allowable contact stress,and meet the requirements,but its reliability is only 83.6398%, which means by traditional method which only counts the mechanical design safety factor is not e-nough;Besides, from the sensitivity of random factors to detss , we know that increasing driven wheel diametercan improve the reliability effectively.
