Labyrinth sealing device having a grease purgeable system

摘要: A grease purgeable dynamic labyrinth sealing device is disclosed which includes a stator having an annular engagement flange on radially inner portion thereof and rotor outer thereof. The the have coacting means for mechanically interlocking rotor. In one embodiment, means, such as, example, plurality of apertures, are operatively formed in allowing excess applied to bearing housing move through out that maintains proper position relative rotatable with shaft. another rotor, provided reducing size contacting surface area between ring or protrusion contacts vice versa. yet stator, increasing resistance away from when exits relatively more shallow portions O-ring grooves allow O-rings compress moved housing.
