Abstract

The invention provides a bearing having a first ring, a second ring, at least one row of rolling elements arranged in a rolling chamber between the first ring and the second ring and a cap attached to the first ring to close the rolling chamber. It is proposed that at least one vibration sensor is attached on the inside of the cap.

First claim

1 . A bearing comprising:
a first ring, a second ring, at least one row of rolling elements arranged in a rolling chamber disposed between the first ring and the second ring and a cap attached to the first ring configured to close the rolling chamber, wherein at least one vibration sensor is attached on the inside of the cap.

2 . The bearing according to claim 1 , wherein the cap is attached to the first ring by a material bonded connection.

3 . The bearing according to claim 2 , wherein the cap is attached to the first ring by brazing.

4 . The bearing according to claim 1 , wherein the cap includes at least one axial end face, and wherein the vibration sensor is attached to the axial end face.

5 . The bearing according to claim 1 , wherein the cap includes at least one radial end face and one axial end face, and wherein the vibration sensor is attached to the radial end face.

6 . The bearing according to claim 1 , wherein the cap is configured to damp vibrations within the cap.

7 . The bearing according to claim 1 , wherein the sensor is arranged in an encapsulation within the cap.

8 . The bearing according to claim 7 , wherein the encapsulation is formed by injection molding.

9 . The bearing according to claim 1 , wherein the vibration sensor is mounted in a metal block connected to the cap.

10 . The bearing according to claim 1 , wherein the cap is a stamped sheet metal part.

11 . The bearing according to claim 1 , further comprising a locking means for avoiding slippage of the first ring.

12 . A machine assembly comprising:
a bearing having;
a first ring,
a second ring,
at least one row of rolling elements arranged in a rolling chamber disposed between the first ring and the second ring and a cap attached to the first ring configured to close the rolling chamber, wherein
at least one vibration sensor is attached on the inside of the cap, wherein
the bearing is mounted such that the sensor is located in a loaded zone of the bearing.

13 . A cap used in a bearing, the bearing comprising:
a first ring, a second ring, at least one row of rolling elements arranged in a rolling chamber disposed between the first ring and the second ring and a cap attached to the first ring configured to close the rolling chamber, wherein at least one vibration sensor is attached on the inside of the cap, and wherein a vibration sensor is attached on the inside of the cap.
