Abstract
A bearing shield is mountable on a bearing outer ring such that the bearing shield extends radially inward toward a standardized bearing inner ring. An inner ring insert is mountable on the inner ring such that the inner ring insert extends a predetermined axial length beyond the inner ring and is engaged by a resilient seal member fixed to the bearing shield to seal an inner ring/outer ring annulus. The inner ring, inner ring insert, and an insert spacer provide a modular inner ring assembly of a predetermined length. Optionally, the inner ring insert can provide a "slinger" or join two inner rings together to form a bearing assembly with multiple rows of rolling elements.
Claims17
A sealing structure for a rolling element bearing having inner and outer rings and rolling elements within an annulus between the inner and outer rings, the sealing structure comprising:
- a bearing shield mountable on the outer ring such that the bearing shield extends radially inwardly toward the inner ring;
- resilient seal means fixed to the bearing shield for sealing the annulus;
- an inner ring insert mountable on the inner ring such that the inner ring insert extends a predetermined axial length beyond the inner ring and is engaged by the resilient seal means as a seal seat;
- and
- insert support means between the inner ring and the inner ring insert for supporting an extension portion of the inner ring insert extending axially beyond the inner ring.
A sealing structure for a rolling element bearing having inner and outer rings and rolling elements within an annulus between the inner and outer rings, the sealing structure comprising:
- a bearing shield mountable on the outer ring such that the bearing shield extends radially inwardly toward the inner ring;
- resilient seal means fixed to the bearing shield for sealing the annulus;
- an inner ring insert mountable on the inner ring such that the inner ring insert extends a predetermined axial length beyond the inner ring and is engaged by the resilient seal means as a seal seat;
- and
- an inner ring spacer between a radially oriented portion of the inner ring insert and the inner ring such that the inner ring spacer provides support for the inner ring insert and spaces a radially oriented end portion of the inner ring insert a predetermined axial distance from the inner ring.
A rolling element bearing comprising:
- an outer ring;
- an inner ring;
- rolling elements within an annulus between the outer ring and the inner ring;
- and
- an inner ring insert mounted on the inner ring such that the inner ring insert extends a predetermined axial length beyond the inner ring;
- and
- insert support means between the inner ring and the inner ring insert for supporting the inner ring insert such that the inner ring insert provides a predetermined axial extension of the inner ring.
A rolling element bearing comprising:
- an outer ring;
- an inner ring;
- rolling elements within an annulus between the outer ring and the inner ring;
- and
- an inner ring insert mounted on the inner ring such that the inner ring insert extends a predetermined axial length beyond the inner ring;
- and
- an inner ring spacer between a radially oriented portion of the inner ring insert and the inner ring such that the inner ring spacer provides support for the inner ring insert and spaces a radially oriented end portion of the inner ring insert a predetermined axial distance from the inner ring.
