齿条的基本齿型和工作齿形 (根据一九四九年重型机械制造工业部提出的 OCT草案,代替 OCT 3058—45) 本标准(根据草案)适用於各种渐开线齿轮和模数大於1公厘的齿轮(蜗轮与螺旋伞齿轮除外)。 齿条的基本齿型 1.齿条的基本齿型(图1)决定於下列各变数: ( 1)啮合深度 h3=2m,m=模数;
(The OCT draft proposed by the Heavy Machinery Manufacturing Industry Ministry in 1949 instead of OCT 3058-45) This standard (according to the draft) is applicable to all types of involute gears and dies Gear larger than 1 mm (except worm gear and helical bevel gear). Basic toothed rack 1. The basic toothed rack (Figure 1) depends on the following variables: (1) the depth of engagement h3 = 2m, m = modulus;
