在机械传动中,齿轮在负荷作用下会产生弹性变形。为了保证一对齿轮的正确啮合,对于重载大马力齿轮箱的齿轮都要求齿形“修缘”:即在齿轮的齿顶或齿根部按一定的高度与修正量修正渐开线齿面。修正量△大小的选择应该容纳下基节偏差和轮齿在负荷状况下的弹性变形,齿形修正量的数 In mechanical transmission, the gear will produce elastic deformation under load. In order to ensure the correct meshing of a pair of gears, the tooth shape “repair” is required for the gears of the heavy-duty high-power gear box: the involute tooth surface is corrected according to a certain height and correction amount on the tooth top or root of the gear. The choice of the amount of correction △ size should accommodate the lower base section deviation and gear tooth load in the elastic deformation, the number of tooth correction
