发明名称 Two stage seal for a bearing assembly
摘要 A bearing assembly includes an inner member having an outer engagement surface and an outer race. The outer race has an inner surface defining a first end and a second end and an inner engagement surface therebetween, the inner engagement surface is positioned on the outer engagement surface of the inner member. A first annular groove is formed in the inner surface, proximate one of the first end and the second end. A second annular groove is formed in the inner surface and is positioned axially inward from the first annular groove. An external seal is positioned in first annular groove and slidably engages the inner member. An internal seal is positioned in the second annular groove and slidingly engages the inner member.

主权项 1. A bearing assembly, comprising: an inner member having an outer engagement surface; an outer race having: an inner surface defining a first end and a second end and an inner engagement surface therebetween, the inner engagement surface being positioned on the outer engagement surface of the inner member and contoured to a shape complementary to the outer engagement surface of the inner member such that the outer engagement surface of the inner member is slidably and rotatably engaged with the inner engagement surface of the outer race;a first annular groove formed in the inner surface, proximate one of the first end and the second end;a second annular groove formed in the inner surface and being positioned axially inward from the first annular groove, the second annular groove defining a mounting channel section; an external seal positioned in the first annular groove and slidably engaging the inner member; and an internal seal positioned in the second annular groove and slidingly engaging the inner member, the internal seal defining an inner lip, an outer lip and a base therebetween, the base directly engaging the mounting channel section; wherein the internal seal is stiffer than the external seal; and wherein the inner lip and the outer lip are flexibly compressed.
