A tapered roller bearing (1) with two coaxial bearing rings (2, 3) and a multiplicity of tapered rollers (4) which are arranged between the bearing rings (2, 3), are guided in a cage (10, 11, 12) and roll on raceways (7, 8) on the bearing rings (2, 3), with a rim (9) at the large diameter of the inner bearing ring (3), wherein the cage (10, 11, 12) is formed of side rings (10, 11) and webs (12) which connect them, with the formation of pockets (13) for the tapered rollers (4), and elastic projections (14) are arranged on one side ring (10), which projections (14) interact with the rim (9) and prestress the cage (10, 11, 12) with the tapered rollers (4) axially against the rim (9). In order to achieve play-free and constraint-free setting of the tapered rollers against the guide rim and to make it possible to apply or introduce active or passive transmission elements to the individual components of the tapered roller bearing, fewer projections (14) than pockets (13) are arranged on the side ring (10) which is close to the rim, preferably only in the region of every second pocket (13) in the case of an even number of pockets (13). An active or passive transmission element (20, 21, 22) is arranged on the rotating bearing ring (2, 3) and/or on the cage (10, 11, 12) and/or on at least one of the tapered rollers (4), and at least one sensor is arranged on a stationary component, which sensor interacts with said stationary component for monitoring the state of the kinematic conditions of the bearing (1) during operation. |
