Abstract
A roller bearing cage includes a first side ring, a second side ring and a plurality of axially-extending bridges connecting the side rings. A pocket for retaining a roller body is defined between the side rings and each two adjacent bridges. The two side rings and the bridges are integrally formed in one-piece. Reinforcement rings are disposed on one or both outer axial sides of the side rings. One or more connecting elements extend axially through the respective bridges, side rings and reinforcement rings. At least one axial end of the connecting element(s) directly or indirectly affixes the reinforcement ring(s) to the side ring(s).
Claims20
A roller bearing cage comprising:
- a first side ring,
- a second side ring,
- a plurality of axially-extending bridges having first and second axial ends that respectively adjoin the first and second side rings, wherein a pocket configured to retain a roller body is defined between the side rings and each two adjacent bridges in a circumferential direction, wherein the two side rings and the plurality of bridges are integrally formed of the same material without gaps or internal breaks,
- at least one reinforcement ring disposed on an axial side of at least one of the first and second side rings that is opposite of the bridges, and
- at least one connecting element extending axially through at least one bridge, at least one side ring and the at least one reinforcement ring, wherein at least one axial end of the connecting element abuts directly or indirectly on the at least one reinforcement ring and connects the at least one reinforcement ring to the adjacent side ring.
A roller bearing cage comprising:
- a first side ring,
- a second side ring,
- a plurality of axially-extending bridges connecting the first side ring to the second side ring, wherein a plurality of pockets configured to retain respective roller bodies are defined between the side rings and circumferentially-adjacent bridges, and wherein the side rings and the plurality of bridges are integrally formed from a single material without gaps or internal breaks,
- a first reinforcement ring disposed on a first outer axial side of the first side ring,
- a second reinforcement ring disposed on a second outer axial side of the second side ring, and
- at least one connecting element extending axially through each bridge, the first and second side rings and the first and second reinforcement rings, wherein outer axial ends of the connecting elements abut, directly or indirectly, on the respective reinforcement rings and affix the reinforcement rings to the respective side rings in an interference fit.
