摘要
Abstract
From the principle ot generating method,an accurate model of involute helical gear was built using three - dimensional modeling software. Based on the deformation compatibility equation for gear pair, the load distribution on each meshing pitch point was calculated with linear programming technique. Then the total load coefficients between different teeth were calculated. U-sing finite element software - ANSYS, the maximum tooth root bending stress in meshing process of the whole gear model was found, thus it can provide evidence for checking tooth bending strength. The results show that the maximum root bending stresses for helical gears are likely to appear when
more teeth are engaged, which is different from spur gears.关键词
