Abstract : the therortical calculation of the bending stress of the root and experimental stress analysis on the modified profile and the standard involute tooth profile were made with the finite element method and the electric resistance strain film method . this indicated that the modified profile was supe rior to the standard involute profiles in terms of the bending strength 文摘:分别用有限元和电阻应变片法对修形齿形和渐开线齿形进行齿根弯曲应力计算与实验应力分析.结果证明在弯曲强度方面修形齿形比标准渐开线齿形更优越
Set up the following 2d parametric models : ( dinitial contour of cone . ( 2 ) six types of inserts : cut insert , conical insert , ovoid insert , chisel insert , gage insert and scoop chisel insert . ( 3 ) twelve types of slots : six slots between the rows of inserts ; six slots on the head of cone 建立了以下几种二维参数化模型： ( 1 )牙轮初始轮廓； ( 2 )六种牙齿，包括平顶齿、锥形齿、球形齿、楔形齿、边楔齿和勺形齿； ( 3 )十二种齿槽，其中六种牙轮齿圈之间的齿槽、六种牙轮顶端的齿槽。
