BEARING

摘要

A rolling element bearing comprising inner and outer rings; a plurality of rolling elements disposed between opposing surfaces of the inner and outer rings; and a bearing shield comprising a first member having an annular surface facing the plurality of rolling elements, the first member either (1) extending from the inner ring towards the outer ring (defining a gap between the first member and the outer ring) and the inner ring having a low surface energy surface adjacent the gap, or (2) extending from the outer ring towards the inner ring (defining a gap between the first member and the inner ring) and the inner ring comprises a low energy surface adjacent the gap. The low energy surfaces each have a surface energy of ≦0.028 N/m.

1. A rolling element bearing comprising:
an inner ring; an outer ring; a plurality of rolling elements disposed between an outer surface of the inner ring and an inner surface of the outer ring; and a bearing shield comprising a first member having an annular surface that faces the plurality of rolling elements, the first member either extending from the inner ring towards the outer ring to define a gap between the first member and the outer ring, or extending from the outer ring towards the inner ring to define a gap between the first member and the inner ring, wherein the first member has a low surface energy surface adjacent the gap; a configuration of one of:
(1) in a configuration where the first member extends from the inner ring, the outer ring has a low surface energy surface adjacent the gap, or(2) in a configuration where the first member extends from the outer ring, the inner ring has a low surface energy surface adjacent the gap; and the low surface energy surfaces each have a surface energy of ≦0.028 N/m.
