Abstract
Изобретение может быть использовано в уплотнени х подшипниковых узлов, работающих в среде, содержащей гр зь, шлам, мелкие частицы твердых веществ. Цель изобретени - повышение эффективности лабиринтного уплотнени путем направлем- ного выдавливани загр знений во внешнюю среду. Выступы вращающегос диска 3 вход т в пазы неподвижного диска 4 и образуют зигзагообразную уплотнительную щель 5. Щель выполнена расшир ющейс в сторону внешней среды. Внутренн поверхность осевого участка щели 5 расположена с подъемом угла наклона в сторону внешней среды. 2 ил.The invention can be used in seals for bearing assemblies operating in an environment containing dirt, sludge, fine particles of solids. The purpose of the invention is to increase the efficiency of labyrinth compaction by direct extrusion of contaminants into the external environment. The protrusions of the rotating disk 3 enter the grooves of the stationary disk 4 and form a zigzag sealing gap 5. The slot is made expanding towards the external environment. The inner surface of the axial portion of the slit 5 is located with the rise of the angle of inclination towards the external environment. 2 Il.
