- 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.
