Abstract
Abstract In order to keep at least part of the axial and tilting forces that act on a bearing away from the stub shaft (99) supporting the bearing rollers (3) (5), the inner ring of the bearing is constructed of a removable section (4) that supports a first set of ball bearings (5). A second set of ball bearings (3) is supported directly on the stub shaft. The removable section (14) extends from the free end of the stub shaft (99) to a point located between a first plane containing the ball centers of the second set (3) and a second plane contacted by the outer surfaces of the balls in the second set. The second plane being between the ball centers of the first and second sets.

Claims Analysis
Total Claims: 10
Claim 1
Independent Claim
249 words
An anti-friction bearing including: outer ring means, inner ring means, axially spaced first and second sets of rolling elements interposed between said inner and outer ring means, a hub having an axial projection supporting said inner ring means and having an axial passage, a bolt entered into said passage through one end thereof, and a closure member at the other end of said passage in operative engagement with said bolt; said first and second sets of rolling elements being rotatably supported, respectively, on first and second separable sections of said inner ring means; said inner ring means including a removable ring section constituting said first section; said projection having a free end, said removable ring section having an axial bore into which the projection extends to mount said removable ring section on said projection at said free end, said closure member operatively engaging said removable ring section at one end thereof that is closer to said free end than is the other end of said removable ring section; said second set of rolling elements being comprised of balls as rolling elements; said other end of said removable ring section being located between first and second planes that are perpendicular to the rotational axis of said bearing; said balls having their centers disposed in said first plane; said balls having their outer surfaces in contact with said second plane; said second plane being interposed between the other end of the removable ring section and the other end of said passage.
Claim 2
Dependent Claim
249 words
An anti-friction bearing including: outer ring means, inner ring means, axially spaced first and second sets of rolling elements interposed between said inner and outer ring means, a hub having an axial projection supporting said inner ring means and having an axial passage, a bolt entered into said passage through one end thereof, and a closure member at the other end of said passage in operative engagement with said bolt; said first and second sets of rolling elements being rotatably supported, respectively, on first and second separable sections of said inner ring means; said inner ring means including a removable ring section constituting said first section; said projection having a free end, said removable ring section having an axial bore into which the projection extends to mount said removable ring section on said projection at said free end, said closure member operatively engaging said removable ring section at one end thereof that is closer to said free end than is the other end of said removable ring section; said second set of rolling elements being comprised of balls as rolling elements; said other end of said removable ring section being located between first and second planes that are perpendicular to the rotational axis of said bearing; said balls having their centers disposed in said first plane; said balls having their outer surfaces in contact with said second plane; said second plane being interposed between the other end of the removable ring section and the other end of said passage.
Claim 3
Dependent Claim
46 words
An anti-friction bearing as set forth in claim 1 in which each rolling element of said first set of rolling elements is of slightly smaller diameter than the diameter of each of said balls; and said removable ring section being force fitted on said axial projection.
Claim 4
Dependent Claim
53 words
An anti-friction bearing as set forth in claim 1 in which said axial bore extends to said one end of said removable ring section and meets same at an edge that is formed with a radius that approaches zero; said closure member engaging said one end at portions thereof adjacent to said edge.
Claim 5
Dependent Claim
37 words
An anti-friction bearing set forth in claim 1 in which said first and second planes have a spacing therebetween which is substantially greater than the spacing between said first set of rolling elements and said second plane.
Claim 6
Dependent Claim
288 words
An anti-friction bearing including: outer ring means, inner ring means, axially spaced first and second sets of rolling elements interposed between said inner and outer ring means, a hub having an axial projection supporting said inner ring means and having an axial passage, a bolt entered into said passage through one end thereof, and a closure member at the other end of said passage in operative engagement with said bolt; said first and second sets of rolling elements being rotatably supported, respectively, on first and second separable sections of said inner ring means; said inner ring means including a removable ring section constituting said first section; said projection having a free end, said removable ring section having an axial bore into which the projection extends to mount said removable ring section on said projection at said free end, said removable ring section being force fitted on said projection, and said closure member operatively engaging said removable ring section at one end thereof that is closer to said free end of said removable ring section; said first set of rolling elements being disposed between first and second planes that are perpendicular to the rotational axis of said bearing; said second set of rolling elements being positioned between third and fourth planes that are perpendicular to the rotational axis of said bearing; said second plane being disposed between said first and third planes, and said third plane being positioned between said second and fourth planes; said other end of said removable ring section being located substantially closer to said third plane than to said second plane; and said third and fourth planes having a spacing therebetween that is substantially greater than twice the spacing between said second and third planes.
Claim 7
Dependent Claim
288 words
An anti-friction bearing including: outer ring means, inner ring means, axially spaced first and second sets of rolling elements interposed between said inner and outer ring means, a hub having an axial projection supporting said inner ring means and having an axial passage, a bolt entered into said passage through one end thereof, and a closure member at the other end of said passage in operative engagement with said bolt; said first and second sets of rolling elements being rotatably supported, respectively, on first and second separable sections of said inner ring means; said inner ring means including a removable ring section constituting said first section; said projection having a free end, said removable ring section having an axial bore into which the projection extends to mount said removable ring section on said projection at said free end, said removable ring section being force fitted on said projection, and said closure member operatively engaging said removable ring section at one end thereof that is closer to said free end of said removable ring section; said first set of rolling elements being disposed between first and second planes that are perpendicular to the rotational axis of said bearing; said second set of rolling elements being positioned between third and fourth planes that are perpendicular to the rotational axis of said bearing; said second plane being disposed between said first and third planes, and said third plane being positioned between said second and fourth planes; said other end of said removable ring section being located substantially closer to said third plane than to said second plane; and said third and fourth planes having a spacing therebetween that is substantially greater than twice the spacing between said second and third planes.
