Bearing assembly having a floating seal

摘要

The bearing assembly concept includes a floating seal arrangement. In one form, a bearing assembly comprises a first bearing member and a second bearing member that is oriented adjacent to the first bearing member. A plurality of bearings is positioned between the first bearing member and the second bearing member. A shield is engaged with the first bearing member, and a floating seal is slidably engaged with the shield and the second bearing member. The shield captures the floating seal adjacent to the second bearing member.

1. A bearing assembly, comprising:
an outer ring having an outer race; an inner ring having an inner race, the inner ring oriented radially inward of the outer ring relative to a longitudinal axis; a plurality of bearings positioned between the outer ring and the inner ring, the plurality of bearings seated in the inner race and the outer race; a shield coupled to the outer ring and defining an axially inner face and an axially outer face; and a floating seal slidably engaged with the shield and the inner ring during operation of the bearing assembly, the floating seal made of at least one of a metallic material and a ceramic material; wherein the floating seal defines an arcuate bearing face engaged with the inner ring, a radial face positioned radially outward from the arcuate bearing face, and a flange extending radially outward from the radial face defining an axial shield face that is engaged with the axially inner face of the shield; wherein the arcuate bearing face that is engaged with the inner ring extends longitudinally beyond the axially inner face and the axially outer face of the shield; and wherein the shield restrains the floating seal adjacent to the shield and the inner ring such that the floating seal can glide relative to the shield and the inner ring during relative rotation between the outer ring and the inner ring.
