Abstract

Описан подшипниковый узел, который имеет новую конструкцию смазочного уплотнения, которое в одном из вариантов его воплощения объединяет преимущества с одной стороны уплотнения лабиринтного типа, а с другой – контактного уплотнения. Предложенное уплотнение содержит кожух, который не вращается и работает в тесном пространственном взаимодействии с вращательным компонентом уплотнения, образовывая канал. Вращательный компонент присоединен к оси и вращается вместе с ней, создавая в этом канале поток смазочного масла. Утечку смазочного масла предотвращает извилистая форма пути прохождения потока в канале уплотнения лабиринтного типа и силы сдвига в потоке жидкости, создаваемые вращением оси. Утечку смазочного масла предотвращает также упругое уплотнение, которое находится в контакте с поверхностью вращательного компонента и ограничивает �
