A bearing, in particular rolling contact bearing (1), having a first bearing ring (2), a second bearing ring (3) and an energy production unit (8) designed as a claw pole generator, wherein the claw pole generator (8) includes a first claw ring (10) with a sequence of first claws (11) and a second claw ring (12) which is offset in the revolving direction of the axis of rotation (6) and has a sequence of second claws, wherein the two claw rings (10, 12) surround an induction coil (9) encircling the axis of rotation (6), wherein the claws (11) of the two claw rings (10, 12) together with a sequence of magnetic poles (14) encircling the axis of rotation (6) form magnetic circuits surrounding the induction coil (9). The objective of providing a bearing which permits retrofitting with a claw pole generator is solved according to the invention in that the claw rings (10, 12) and the induction coil (9) are fastened by a first support ring (24; 24′) on an end surface (16) of the first bearing ring (2), in that the magnetic poles (14) are fastened on the end surface (20) of the second bearing ring (3) by a second support ring (18), wherein the magnetic poles (14) are connected in a magnetically conductive manner to one another by a return-path ring made from a magnetically conductive material, and wherein the two claw rings (10, 12) are connected in a magnetically conductive manner by a flux-conducting ring (17). |
