Государственный стандарт Союза ССР ГОСТ 24737-81 (СТ СЭВ 838-78) "Основные нормы взаимозаменяемости. Резьба трапецеидальная однозаходная. Основные размеры" (введен в действие постановлением Госстандарта СССР от 30 апреля 1981 г. N 2262)

Basic norms of interchangeability. Trapezoidal single-start screw thread. Basic dimensions

Дата введения 1 января 1982 г.

Взамен ГОСТ 9484-73

в части основных размеров

1. Настоящий стандарт распространяется на трапецеидальную однозаходную резьбу с профилем по ГОСТ 9484-81, диаметрами и шагами по ГОСТ 24738-81 и устанавливает номинальные диаметры резьбы.

Стандарт полностью соответствует СТ СЭВ 838-78.

2. Номинальные диаметры резьбы должны соответствовать указанным на чертеже 1 и в таблице.

Значения диаметров вычислены по формулам:

      D  = d - 2 х H  = d - P;

       1            1

      D  = d + 2 х a ;

       4            с

      d  = D  = d - Н  = d - 0,5 х P;

       2    2        1

      d  = d - 2 х h .

       3            3
