Bearing with an energy production unit, in particular self-aligning roller bearing for the mounting of a roller

Abstract

The invention relates to a bearing, in particular rolling contact bearing (1), comprising 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) comprises 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 problem 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 means of a second support ring (18), wherein the magnetic poles (14) are connected in a magnetically conductive manner to one another by means of 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 means of a flux-conducting ring (17).

Description

technical field [0001] The invention relates to a bearing according to the preamble of claim 1 and to a bearing arrangement according to claim 11 for the rotatable mounting of a roll, in particular a guide roll for a paper web. Background technique [0002] It is known from practice that, during operation, electrical energy is generated from the rotational movement of bearings, in particular rolling bearings or sliding bearings. For this purpose, in particular rolling bearings are known in which the energy generation unit is structurally integrated. In particular rolling bearings are known in which the energy generating unit is designed as a claw pole generator. The claw pole generator here comprises a first claw ring with a series of first claws extending in the circumferential direction of the rolling bearing, a second claw ring with a series of second claws extending in the circumferential direction of the rolling bearing, separated by two An induction coil surrounded b...
