Задача №22.21
Условие
Камень A качающейся кулисы механизма строгального станка приводится в движение зубчатой передачей, состоящей из зубчатки D и зубчатки E, несущей на себе ось камня A в виде пальца. Радиусы зубчаток R=0,1 м, R1=0,35 м, O1A=0,3 м, расстояние между осью O1 зубчатки E и центром B качания кулисы O1B=0,7 м. Определить угловую скорость кулисы в моменты, когда отрезок O1A либо вертикален (верхнее и нижнее положения), либо перпендикулярен кулисе AB (левое и правое положения), если зубчатка имеет угловую скорость ω=7 рад/с. Точки O1 и B расположены на одной вертикали.Решение
