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 supporting the bearing rollers, the inner ring of the bearing is constructed of two sections (2) (3) that support individual sets of ball bearings. The inner ring sections abut one another in a plane perpendicular to the bearing rotational axis. One of these inner ring sections (3) is force fitted on the stub shaft at the free end thereof and has a larger cross section than the other inner ring section (2). A necked-down bolt and mating closure nut, the latter being adjacent inner ring section (3), cooperate to maintain the other bearing elements assembled in operative relationship.

Claims Analysis
Total Claims: 16
Claim 1
Independent Claim
190 words
An anti-friction bearing including: outer ring means, inner ring means, axially spaced first and second sets of rollers interposed between said inner and outer ring means, a hub having an axial projection supporting said inner ring 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 inner ring means including a first ring section supporting said first set of rollers and a second ring section supporting said second set of rollers; said first and second ring sections being constituted by separable elements; said first ring section being interposed between said second ring section and said closure member; said first ring section having a larger axial cross section than said second ring section; said first and second ring sections being provided with axial first and second bores, respectively, into which said projection is entered; said first bore being of slightly smaller diameter than said second bore; the thickness of said first ring section measured in a radial direction being slightly greater than that of said second ring section.
Claim 2
Dependent Claim
190 words
An anti-friction bearing including: outer ring means, inner ring means, axially spaced first and second sets of rollers interposed between said inner and outer ring means, a hub having an axial projection supporting said inner ring 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 inner ring means including a first ring section supporting said first set of rollers and a second ring section supporting said second set of rollers; said first and second ring sections being constituted by separable elements; said first ring section being interposed between said second ring section and said closure member; said first ring section having a larger axial cross section than said second ring section; said first and second ring sections being provided with axial first and second bores, respectively, into which said projection is entered; said first bore being of slightly smaller diameter than said second bore; the thickness of said first ring section measured in a radial direction being slightly greater than that of said second ring section.
Claim 3
Dependent Claim
61 words
An anti-friction bearing as set forth in claim 1 in which said first ring section has an end surface remote from said second ring section; said first bore extending to said end surface and meeting same at an edge having a radius of rounding that approaches zero; said closure member engaging said end surface at portions thereof adjacent to said edge.
Claim 4
Dependent Claim
45 words
An anti-friction bearing as set forth in claim 1 in which said bolt includes an axial portion disposed within said passage, and there is a substantial space between the outside of the axial portion of said bolt and a boundary wall which defines said passage.
Claim 5
Dependent Claim
36 words
An anti-friction bearing as set forth in claim 3 in which said closure member includes a hollow necked-down portion that extends into said passage and is provided with internal threads in operative engagement with said bolt.
Claim 6
Dependent Claim
211 words
An anti-friction bearing including: outer ring means, inner ring means, axially spaced first and second sets of rollers interposed between said inner and outer ring means, a hub having an axial projection supporting said inner ring 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 inner ring means including a first ring section supporting said first set of rollers and a second ring section supporting said second set of rollers; said first ring section being interposed between said second ring section and said closure member; said first ring section having a larger axial cross section than said second ring section; said first and second ring sections being engaged at a first plane that is perpendicular to the rotational axis of said bearing; said second set of rollers being comprised of balls as rolling elements; said first plane being parallel to and disposed between a second and a third plane; said balls having their centers disposed in said second plane; said balls having their outer surfaces in contact with said third plane; said third plane being interposed between said first plane and the other end of said passage.
Claim 7
Dependent Claim
211 words
An anti-friction bearing including: outer ring means, inner ring means, axially spaced first and second sets of rollers interposed between said inner and outer ring means, a hub having an axial projection supporting said inner ring 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 inner ring means including a first ring section supporting said first set of rollers and a second ring section supporting said second set of rollers; said first ring section being interposed between said second ring section and said closure member; said first ring section having a larger axial cross section than said second ring section; said first and second ring sections being engaged at a first plane that is perpendicular to the rotational axis of said bearing; said second set of rollers being comprised of balls as rolling elements; said first plane being parallel to and disposed between a second and a third plane; said balls having their centers disposed in said second plane; said balls having their outer surfaces in contact with said third plane; said third plane being interposed between said first plane and the other end of said passage.
