Задача №24.13
Условие
В блоке системы «Триплекс» на валу a — a жестко насажен цепной блок A; на тот же вал свободно насажена втулка b с подъемной цепью и грузом, наглухо соединенная с рукояткой B. На каждый палец рукоятки свободно насажены две шестерни II и III, спаренные между собой, шестерни II сцеплены с шестерней I, заклиненной на валу a — a, шестеренки III сцеплены с неподвижным зубчатым колесом IV. Определить отношение угловых скоростей вращения вала a — a и втулки b, если числа зубцов колес I, II, III и IV соответственно равны: z1=12, z2=28, z3=14, z4=54.Решение
