TAPER ROLLER BEARING Russian patent published in 2016 - IPC F16C33/51 F16C19/36 F16C33/36 F16C33/46 

FIELD: machine building.

SUBSTANCE: invention relates to a taper roller bearing used as a support with a possibility of rotation of the first machine part relative to the second machine part, in particular, for the support with a possibility of the rotor shaft rotation of a wind-driven plant. The taper roller bearing contains taper rolling bodies (6) and cage segments (7). The segment (7) contains two opposite peripheral jumpers (10), that pass, each, between the first peripheral end and the second peripheral end of the segment (7), and at least two opposite connecting jumpers (11), connecting with each other both the jumpers (10) and together with the jumpers (10) creating at least one pocket (12) for the rolling body (6) location. The jumpers (10, 11) have pocket sides limiting the pockets (12). The jumpers (10) and the jumpers (11) located in the zone of the first peripheral end and second peripheral end have peripheral sides opposite to the pocket sides. The jumpers (11) have, each, on their pocket side the first guide surface, having a concave shape, and the second guide surface, having a concave shape, and the jumpers (11) located in the zone of the first peripheral end or the second peripheral end have, each, additionally on their peripheral side the first guide surface, having a concave shape, for partial surrounding of the rolling body (6) in its circumferential direction. The first guide surfaces and the second guide surfaces on the pocket sides of the jumpers (11), adjacent to the same pocket (12) lock with geometrical closure the rolling body (6) located in the same pocket (12) protecting against fall out in the first direction and in the second direction opposite to the first direction, thus locking the rolling body (6) in the pocket (12) without the possibility of loss. The cage segments (7) are directed by the rolling bodies (6).

EFFECT: development of the cage design, suitable for the use in especially large roller bearings, in particular in the roller bearing of the wind-driven plant, wherein the cage segments are provided with good installation ability upon low weight, and the pocket shape ensures the possibility of reliable location of the rolling body and reliable directing of the cage segment over the rolling body.
