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.

Cage segment of a tapered roller bearing, and tapered roller bearing

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.

A bearing cage for a rolling-element bearing includes a plurality of bearing cage segments configured to receive rolling elements in rolling-element pockets. Also included is at least one assembly wire, and each of the cage segments includes a coupling arrangement configured to thread the bearing cage segment onto the at least one assembly wire such that at least one rolling-element pocket is formed by two of the plurality of bearing cage segments adjacent in the circumferential direction that are threaded on the assembly wire. The bearing cage also includes an assembly device configured to convey an end of the assembly wire from an installation position to an axially far-side coupling arrangement of a bearing cage segment, through the axially far-side coupling arrangement of all bearing cage segments located on a bearing inner ring, and back again towards the installation position.

Bearing cage, bearing cage segment, and method for assembling the bearing cage

A pocket cage of synthetic material for roller bearings including a plurality of rollers spaced circumferentially, consisting of side rings and ribs arranged between them, whose pocket-side working faces are adapted to the roller shape, each rib having a first section arranged in the region of the arc separating the rollers in the circumferential direction of the bearing, and a second section holding the rollers in the radial direction of the bearing, characterized in that the pockets are widened at least in the region of a side ring by reduction of the holding sections.
