  • Patent number: 9458886
    Abstract: A first rolling-element guided cage segment of a tapered roller bearing has first and second circumferential ends and first and second mutually opposing circumferential bridges extending between the circumferential ends and first and second mutually opposing connecting bridges connecting the first and second circumferential bridges. Inner pocket sides of the circumferential bridges and the connecting bridges form a pocket for receiving a rolling element. A first positioning aid is located at the first circumferential end and a second positioning aid is located at the second circumferential end, the positioning aids being configured such that a correct-position arrangement of adjacent cage segments is recognizable from the interaction of the first positioning aid and the second positioning aid.

  • Patent number: 9366293
    Abstract: A tapered roller bearing includes cage segments each having a pocket that retains one conical rolling element. The pocket is formed by two mutually-opposing circumferential bridges, which each extend between first and second circumferential ends of the cage segment, and at least two mutually-opposing connecting bridges, which connect the two circumferential bridges. The circumferential and connecting bridges have pocket sides, which delimit the pocket. The connecting bridges disposed in the region of the first and second circumferential ends each have a concavely-shaped first guide surface on their pocket and circumferential sides that partially enclose one rolling element. When a rolling element is disposed between the first circumferential end of one cage segment and the second circumferential end of the adjacent cage segment, the circumferential bridges of the two adjacent cage segments do not touch during operation.
