Abstract

Official abstract text for this publication.

A bearing isolator seal includes a rotor and stator wherein the stator has inboard and outboard radial projections which define a groove bounded by groove side faces and a groove bottom face. The rotor extends radially and then axially so as to lie closely adjacent to the terminal end of the outboard radial projection on the stator to define an entrance passageway. The bearing isolator seal includes a surface geometry which is believed to result in improved exclusion of contaminants, particularly from high velocity water spray, wherein the entrance passageway is angled to increase the rotational effects of exclusion during shaft rotation, and wherein the groove side faces are also angled to assist in redirecting spray and other contaminants away from the passageway.

First claim

Opening claim text (preview).

What is claimed: 1. A bearing isolator seal for sealing a bearing cavity between an equipment housing and a rotatable shaft, said bearing isolator seal comprising: a housing-mountable stator having a mounting portion engagable with an equipment housing, an inboard radial flange located for axial abutment against an exterior end face of an equipment housing, and an outboard radial flange spaced axially from said inboard radial flange, said inboard and outboard radial flanges being…
