Abstract
The present invention provides a labyrinth sealing assembly for placement between a shaft and a bearing housing comprising an annular stator having a body portion, an axially inner engagement surface, an axially inner extending portion extending from a radially outer end of the stator, an axially inner extending member extending from a radially inner end of the stator, and a keeper lip extending radially outward from the axially inner extending surface of the radially inner end of the stator, and an annular rotor having an axially outer engagement surface having a plurality of wear ridges on a radially outer engagement surface, and a keeper notch arrangement on a radially inner surface comprising a recess. The keeper lip engages the keeper notch to provide a snap fit between the rotor and stator.
Claims19
A labyrinth sealing assembly for placement between a shaft and a bearing housing comprising:
- an annular stator statically associated with an axle and having at least one rotor engagement surface;
- an annular rotor associated with a hub, wherein the rotor comprises at least one wear ridge that is associated with the at least one rotor engagement surface of the stator and the rotor and stator engage so as to form a labyrinth path on the radially inward side of the sealing assembly.
A labyrinth sealing assembly for placement between a shaft and a bearing housing comprising:
- an annular stator statically associated with an axle;
- an annular rotor associated with a hub, wherein the rotor comprises at least one wear ridge that is associated with a rotor engagement surface on a bearing face, said rotor and said stator being configured to form a labyrinth pathway on the radially inward side of the sealing assembly.
