【摘要】：以双压力角非对称细高齿齿轮为研究对象,首先建立了齿轮参数设计的模型方法,采用ANSYS对齿轮啮合的综合应力和接触应力进行仿真。结果显示,双压力角非对称细高齿主动轮的综合应力峰值出现在中间齿的根部,从动轮应力峰值为主动轮的1.7倍;双压力角非对称细高齿轮的接触应力最大值出现在曲率半径最小的位置,当齿轮重合度小于2.4时,局部应力峰值急剧增加,接触应力的峰值出现在齿面中部的位置。
[Abstract]:In this paper , a model method of gear parameter design is established based on the asymmetric high - tooth gear with double pressure angle . The synthetic stress and contact stress of the gear mesh are simulated by ANSYS . The results show that the peak of the composite stress of the asymmetric high - tooth driving wheel of the double - pressure angle appears at the root of the middle tooth , the stress peak of the driven wheel is 1.7 times of the driving wheel , and the peak value of the contact stress of the double - pressure angle asymmetric fine high gear appears at the minimum curvature radius . When the coincidence degree of the gear is less than 2.4 , the peak of the local stress increases sharply , and the peak value of the contact stress appears in the middle of the tooth surface .
