The chainring carrier is rotatably connected to a chainring shaft, which in turn is rotatably connected to the shaft. The sprocket shaft has a section on a magnetization. A sensor is provided which detects a change in the magnetization at a torque present in the region of the magnetization.

This area is formed in a transducer, which sits as a cylindrical sleeve, for example, on a shaft. The torque sensor faces the transducer.

From the DE 692 22 588 T2 For example, an annular magnetized torque sensor is known.

The sensor comprises a magnetically coded primary sensor, which may be formed from a seated on the roll stabilizer sleeve. Alternatively, the magnetically encoded primary sensor may be formed by a sleeve which is introduced into a cavity of a hollow flange of the roll stabilizer.

From the DE 10 2015 202 240 B3 An arrangement is known for measuring a force acting on a machine element and / or a moment acting on a machine element using the inverse-magnetostrictive effect. The machine element has at least two circumferentially extending magnetization regions with magnetically neutral regions therebetween. The arrangement comprises at least three magnetic field sensors which are each designed to measure a directional component of a magnetic field caused by the magnetization and by the force or the moment.

The object of the present invention, starting from the state of the art, is to be able to make the measurement of forces and moments on a bearing arrangement more accurate, for which purpose in particular the effect of magnetic interference fields is to be minimized and a differentiation of differently aligned forces and moments is to be enabled.

The stated object is achieved by a bearing arrangement according to the appended claim 1.

The bearing arrangement according to the invention is primarily used for rotational bearing of a rotating machine element with respect to a further machine element. For this purpose, the bearing assembly comprises a first bearing ring and a relative to the first bearing ring rotatable about an axis second bearing ring. In that regard, the bearing assembly according to the invention represents a rotary bearing. On the bearing assembly, in particular on the first bearing ring, acts at least one force and / or at least one moment. The force or the moment acts on the first bearing ring, which leads to mechanical stresses and the first bearing ring usually deforms slightly.

The bearing arrangement according to the invention further comprises a measuring arrangement for measuring the force acting on the first bearing ring and / or the torque acting on the first bearing ring. The force acting on the first bearing ring or the force acting on the first bearing ring moment can act directly or indirectly on the first bearing ring.

The measuring arrangement comprises at least one ring of a magnetostrictive material. The one or more rings sit on the first bearing ring. The axis of the bearing assembly also represents each an axis of the rings; ie that the ring or rings and the bearing rings coaxial are arranged to each other. The one ring or the plurality of rings have in their entirety at least one permanent magnetization revolving around the axis. If there are several of the circulating permanent magnetizations, these are adjacent in the axial direction. The circulating permanent magnetizations are preferably the same except for their sense of rotation. The axis of the bearing assembly also represents in each case an axis of a rotating permanent magnetization or the plurality of rotating permanent magnetizations. The one circumferential permanent magnetization or the plurality of circumferential permanent magnetizations are each closed around the axis. The one circumferential permanent magnetization or the several circumferential permanent magnetizations preferably each extend on a circular path. The one circumferential permanent magnetization or the several circumferential permanent magnetizations can each also be regarded as a trace along a circular path in the respective ring.

The magnetic field sensors are each arranged opposite the one circumferential permanent magnetization or with respect to one of the several circulating permanent magnetizations, ie. H. in the vicinity of the respective permanent magnetization, but spaced from the respective permanent magnetization. The spacing leads to a distance in the radial direction, in the tangential direction and / or in the axial direction. The magnetic field sensors are each arranged opposite the one circumferential permanent magnetization or with respect to the individual circulating permanent magnetizations. Thus, the magnetic field sensors are arranged opposite to a circulating permanent magnetization or with respect to the individual revolving permanent magnetizations and designed to measure a magnetic field caused by the respective permanent magnetization and by the force and / or by the moment. The measuring arrangement is thus based on the inverse magnetostrictive effect. The one ring or the plurality of rings form a primary sensor within the measuring arrangement and therefore each represent a measuring ring. For this sits one ring or sit the multiple rings on the first bearing ring, so that the forces acting on the first bearing ring and / or Moment acting on the first bearing ring also leads to stresses in the one ring or in the plurality of rings. The mechanical stresses in the ring or in the rings lead, together with the respective permanent magnetization due to the inverse-magnetostrictive effect to a magnetic field which is measurable outside the ring or the rings. The magnetic field sensors are designed to measure the magnetic field caused by the respective permanent magnetization and by the force or the magnetic field caused by the respective permanent magnetization and by the moment. Consequently, the magnetic field sensors form a secondary sensor within the measuring arrangement based on the inverse magnetostrictive effect. The primary sensor, d. H. one ring or the plurality of rings with the at least one circumferential permanent magnetization serves to convert the force to be measured or the moment to be measured into a corresponding magnetic field, while the secondary sensor enables the conversion of this magnetic field into an electrical signal. The magnetic field sensors are each designed at least for measuring a directional component of the magnetic field produced.
