Bearing isolator seal for rotating shaft |
| abstract |
A bearing isolator seal (10) includes a rotor (23) and stator (24) wherein the stator (24) has inboard (26) and outboard (32) radial projections which define a groove (34) bounded by groove side faces (36, 37) and a groove bottom face (38). The rotor (23) extends radially (35) and then axially (36) so as to lie closely adjacent to the terminal end (33) of the outboard radial projection (32) on the stator (24) to define an entrance passageway (39). The bearing isolator seal (10) includes a surface geometry which is believed to result in improved exclusion of contaminants, particularly from high velocity water spray, wherein the entrance passageway (39) is angled to increase the rotational effects of exclusion during shaft (12) rotation, and wherein the groove side faces (36, 37) are also angled (38A, 38B) to assist in redirecting spray and other contaminants away from the passageway (39). |
