Rolling bearing sensor with anti-rotational means
View Patent ↗A rolling bearing sensor, especially a rotational speed sensor, having a housing and a signal pick-up which is arranged in the housing in a manner secured against rotation and is arranged, with the housing, in a stationary receptacle in a stationary part of a rolling bearing or in a stationary component adjoining a rolling bearing, for example, an axle journal, where the housing has an outer design via which the rolling bearing sensor in the receptacle is secured against rotation in a form-fitting manner. The sensor may have a groove which runs in the axial direction and interacts with a screw or a projection. Alternatively, a securing element which predefines a defined angular position may be pushed onto the sensor.
1. A roller bearing sensor secured to a non-rotatable portion of a roller bearing, comprising:
a retainer secured to said non-rotatable portion of said roller bearing;
a housing mounted in said retainer;
a holding part arranged within said housing and at least partially co-planar with said housing; and,
a signal pickup mounted with anti-rotation locking within said housing and said holding part, said signal pickup arranged at least partially co-planar with said housing and said holding part and said signal pickup positioned a distance from a rotatable portion of said roller bearing,
wherein said housing has an outer shaping by which the roller bearing sensor is secured against turning with form fit in the retainer.
2. The roller bearing sensor recited in claim 1 , wherein said shaping is formed by a groove running in an outer wall of said housing in a mounting direction of said roller bearing sensor.
3. The roller bearing sensor recited in claim 1 , wherein said housing is formed of a thin-walled metal part and the shaping is implemented by a plastic deformation of the metal part.
4. The roller bearing sensor recited in claim 1 , wherein said housing is designed as a plastic injection molded part.
5. The roller bearing sensor recited in claim 1 , wherein the shaping is formed by a securing element connected to said housing so it cannot rotate, supported on the fixed part of the roller bearing.
6. The roller bearing with a roller bearing sensor recited in claim 1 , wherein the roller bearing sensor is secured against rotation by means of a securing part supported on the shaping.
7. An arrangement of a roller bearing sensor comprising:
a retainer secured to a fixed (part of a roller bearing;
a housing mounted in said retainer;
a holding part arranged within said housing and at least partially co-planar with said housing; and,
a signal pickup locked against rotation mounted in the housing and said holding part, said signal pickup arranged at least partially co-planar with said housing and said holding part and said signal pickup arranged a distance from a rotatable part of the roller bearing;
wherein the housing has an outer shaping by which the roller bearing sensor is secured against rotation with form fit in the retainer.
8. The arrangement of a roller bearing sensor recited in claim 7 , wherein the roller bearing sensor is designed according to claim 1 .
9. The arrangement of a roller bearing sensor recited in claim 7 , wherein the roller bearing sensor is designed according to claim 2 .
10. The arrangement of a roller bearing sensor recited in claim 7 , wherein the roller bearing sensor is designed according to claim 3 .
11. The arrangement of a roller bearing sensor recited in claim 7 , wherein the roller bearing sensor is designed according to claim 4 .
12. The arrangement of a roller bearing sensor recited in claim 7 , wherein the roller bearing sensor is designed according to claim to 5 .
13. A roller bearing sensor, comprising:
a retainer secured to a fixed component adjacent to a roller bearing;
a housing mounted in said retainer;
a holding part arranged within said housing and at least partially co-planar with said housing; and,
a signal pickup mounted with anti-rotation locking within said housing and said holding part, said signal pickup arranged at least partially co-planar with said housing and said holding part and said signal pickup positioned a distance from a rotatable portion of said roller bearing;
wherein said housing has an outer shaping by which the roller bearing sensor is secured against turning with form fit in the retainer.
14. The roller bearing sensor recited in claim 13 , wherein the shaping is formed by a securing element connected to said housing so it cannot rotate, supported on the adjacent component.
