Задача №24.9

Условие

Редуктор скоростей с планетарной передачей состоит из неподвижного солнечного колеса 1, жестко связанного с валом I, рамки, свободно вращающейся вокруг осей I и II с угловой скоростью Ω, двух шестеренок 2 и 3, жестко связанных между собой и свободно насаженных на ось EF, вращающуюся вместе с рамкой, и ведомой шестерни 4, жестко связанной с валом II. Определить отношение угловой скорости вала II к угловой скорости рамки, если шестеренки имеют следующее число зубцов: z1=49, z2=50, z3=51, z4=50.

Решение





Предыдущая задача №8
Редуктор скоростей состоит из неподвижной шестеренки радиуса r1=40 см, двух бегающих шестеренок радиусов r2=20 см и r3=30 см, спаренных между собой, и шестеренки с внутренним зацеплением радиуса r4=90 см, сидящей на ведомом валу. Ведущий вал и кривошип, несущий оси бегающих шестеренок, делают n1=1800 об/мин. Найти число оборотов в минуту ведомого вала.
