SPLIT CYLINDRICAL ROLLER BEARING

摘要

A split cylindrical bearing assembly having a first split outer ring with an inner radial self-aligning feature aligning axially with a second split outer ring having an outer radial self-aligning feature, the second split outer ring having two sections that are fixedly assembled and circumferentially aligned. A split inner ring having two sections fixedly assembled and circumferentially aligned is assembled within and axially aligned with the second split outer ring, and a split cage retaining rolling elements disposed between the second split outer ring and the split inner ring. Also the split cylindrical bearing assembly assembled onto a shaft and into a housing assembly.

主权项

1. A bearing comprising:
a first split outer ring including:
a first section having a first self aligning surface on an inner radial surface and a first mounting surface on an outer radial surface;a second section having a second self aligning surface on an inner radial surface and a second mounting surface on an outer radial surface; and,the first section and the second section at least partially circumferentially aligned such that the first self-aligning surface is at least partially circumferentially aligned with the second self-aligning surface and the first mounting surface is at least partially aligned with the second mounting surface; a second split outer ring assembled within the first split outer ring including:
a first section having a first bearing raceway on an inner radial surface, a first self-aligning surface on an outer radial surface and at least two retention shoulders at opposite axial ends;a second section having a second bearing raceway on an inner radial surface, a second self-aligning surface on an outer radial surface and at least two retention shoulders at opposite axial ends;a plurality of fasteners joining the first section and the second section such that a first continuous bearing raceway, a first continuous self-aligning surface and at least two continuous retention shoulders are formed; and,the first continuous self-aligning surface at least partially aligned with the first split outer ring first and second self-aligning surfaces; a split inner ring axially aligned with the second split outer ring and assembled within the second split outer including:
a first section having a first bearing raceway on an outer radial surface and a first shaft mounting surface on an inner radial surface;a second section having a second bearing raceway on an outer radial surface and a second shaft mounting surface on an inner radial surface; anda plurality of fasteners joining the first and second sections such that a second continuous bearing raceway is formed from the first and second section bearing raceways; and, a plurality of rolling elements retained by at least two circumferentially aligned semi-circular cage halves and disposed between the second split outer ring and the split inner ring.
