Abstract
A roller bearing comprises at least two rows of rollers disposed between an inner ring and an outer ring. At least two tracks guide the respective rows of roller and are defined in the axial direction of the inner ring or the outer ring. At least one flange abuts axial ends of axially-adjacent rows of rollers and extends radially from a radially outer side or a radially inner side of the inner ring or the outer ring. At least one recess is defined on the side of the inner ring or the outer ring that is opposite of the radially outer side or the radially inner side of the inner ring or the outer ring, from which the at least one flange radially extends. The at least one recess at least partially overlaps the at least one flange in the axial direction.
Claims20
A bearing assembly including an at least two-rowed roller bearing comprising:
- at least one outer ring,
- at least one inner ring and
- at least two rows of roller bodies disposed between the inner ring and the outer ring,
- wherein at least one of the inner ring and the outer ring includes at least two tracks disposed axially adjacent to each other and configured to respectively guide the at least two rows of roller bodies,
- at least one flange is configured to abut axial ends of the roller bodies and extends radially from a radially outer side or a radially inner side of at least one of the inner ring and the outer ring between the at least two tracks,
- at least one recess is defined on the at least one of the inner ring and the outer ring, from which the at least one flange radially extends, within a length of the at least one flange in an axial direction of the roller bearing, and
- the at least one recess is disposed on the radially outer side or the radially inner side of at least one of the inner ring and the outer ring that is opposite of the radially outer side or the radially inner side, from which the at least one flange radially extends.
A roller bearing comprising:
- at least one outer ring,
- at least one inner ring,
- at least two axially-adjacent rows of roller bodies disposed between the inner ring and the outer ring,
- at least two tracks configured to respectively guide the at least two rows of roller bodies, the at least two tracks being defined in an axial direction of at least one of the inner ring and the outer ring,
- at least one flange configured to abut axial ends of axially-adjacent rows of roller bodies, the at least one flange extending in a radial direction from a radially outer side or a radially inner side of at least one of the inner ring and the outer ring, and
- at least one recess defined on a side of the at least one of the inner ring and the outer ring that is opposite of the radially outer side or the radially inner side of at least one of the inner ring and the outer ring, from which the at least one flange radially extends, the at least one recess at least partially overlapping the at least one flange in the axial direction.
