摘要:
A device for measuring rotation speed or rotation direction of a rolling-contact bearing which is attached to the bearing. The bearing has an inner and an outer bearing ring with a row of bearing rolling elements between them. A respective sensor unit is at each axial end of the bearing rings. Each sensor unit includes a pulse transmitter ring on one of the inner and outer bearing rings and a sensor on the other of the bearing rings, and the sensor units operate independently. Each sensor unit is force-fit or positively connected to one of the bearing rings, with the pulse transmitter ring connected to one of the bearing rings and the sensor to the other bearing ring.

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).

The invention relates to a roller bearing comprising curved running paths, in addition to roller bodies and strain gauge sensors which are arranged between said running paths, said sensors being located in a groove on the outer diameter of the outer ring and/or on the inner diameter of the inner ring. The length of two adjacent strip conductor sections of the strain gauge sensor varies in such a way as to measure the angular position of the roller bodies between the strip conductors.

A metal window cage for a rolling bearing and supporting cylinder rollers. The cage having at least one ladder-shaped bent segment which is bent around to define the window cage. A joint is formed at adjacent cage segment ends which are interlocked in a dovetail shape lock at the segment ends. A connecting element connects the segment ends. The crosspieces at intervals along the cage segment and the connecting element at the joint are encapsulated by being molded over. Cylinder roller retaining clips are provided at the connecting element at the segment ends at the joint and also at the crosspieces between neighboring windows for cylinder rollers. The clips project radially inwardly to prevent the rollers from leaving the cage prior to installation of the cage and rollers in a bearing. The crosspieces and clips there are also molded over to retain them at the cage.
