Bearing assembly and locking collar
A bearing assembly comprising an inner ring for mounting on a shaft, an outer ring disposed concentrically about the inner ring, a plurality of roller elements interposed between the inner and outer rings. The inner ring includes fingers which extend axially from a side thereof and terminate in outer annular end walls. A compressible annular locking collar is positioned circumferentially about the fingers. The locking collar has a larger inside diameter and a smaller inside diameter. The larger inside diameter has an axial length not greater than the axial length of the fingers. The larger inside diameter is sized to fit over and engage the fingers. The smaller inside diameter is sized to define an annular radially extending wall which engages the outer annular end walls of the fingers. The locking collar has a fastener screw for causing the larger diameter of the locking collar to compress the fingers into locking engagement with the shaft.
1. A bearing assembly comprising an inner ring for mounting on a shaft,
an outer ring disposed concentrically about said inner ring, a plurality of roller elements interposed between said inner and outer rings, said inner ring including fingers extending axially from a side thereof and terminating in outer annular end walls, a compressible annular locking collar positioned circumferentially about said fingers, said locking collar having a larger inside diameter and a smaller inside diameter, said larger inside diameter having an axial length not greater than the axial length of said fingers, said larger inside diameter sized to fit over and engage said fingers, said smaller inside diameter sized to define an annular, radially extending wall which engages said outer annular end walls of said fingers, and said locking collar having a fastener screw operable for causing said larger diameter of said locking collar to compress said fingers into locking engagement with said shaft.
2. The bearing assembly of claim 1 in which said axial length of said larger inside diameter is less than said axial length of said fingers.
