- a sensor for detecting a rotation state of a bearing is directly attached to the outer ring.
- the “rotation state of the bearing” means the number and direction of rotation of the inner ring, the vibration of the bearing, and the temperature of the outer ring. Therefore, a rotation sensor, a vibration sensor, or a temperature sensor can be applied as a sensor for detecting the rotation state.
- a double-row cylindrical roller or a double-row tapered roller can be applied as the rolling element which is one of the components of the above-described bearing.
- the sensor for detecting the rotation state of the bearing is directly attached to the outer ring, so that the sensor is firmly attached to the outer ring having high rigidity. It becomes easy to accurately measure the rotation state such as the generated vibration with a sensor.
- the present invention is applicable to a bearing that rotatably supports an axle of a railway vehicle.
- the upper portion of the outer diameter of the outer ring is limited due to the mounting structure of the bearing to the vehicle.
- a housing is provided in the housing.
- the housing is provided above the outer diameter of the outer ring, it is desirable that the sensor is disposed below the outer diameter of the outer ring. With such a structure, it is possible to directly attach the sensor to the outer ring without interfering with the housing.
- a structure may be used in which a convex portion that protrudes in the radial direction is provided on a part of the outer diameter of the outer ring, and the sensor is mounted on the end face of the convex portion.
- the protrusion formed on the outer diameter of the outer ring contacts the housing to prevent rotation, thereby preventing the sensor lead wire from breaking.
- the senor for detecting the rotation state of the bearing is directly attached to the outer ring, the sensor is firmly attached to the outer ring having high rigidity. It is easy to accurately measure the rotation state such as by a sensor. As a result, the quality and reliability of the product are greatly improved, and when used for railway vehicle axles, a bearing with a sensor that is excellent in terms of safety can be provided.
- FIGS. 1 to 10 illustrate an embodiment in which the bearing with a sensor of the present invention is applied to an axle bearing of a railway car such as a freight car.
- FIGS. 1 to 6 show an outer diameter lower portion of an outer ring.
- 7 to 10 show an embodiment in which a sensor is attached to the upper portion of the outer diameter of the outer ring. In the embodiments shown in FIGS. 7 to 10, the housing is not shown.
- the sensor-equipped bearing in the embodiment shown in Figs. 1 to 3 includes a pair of inner races 2 adjacent in the axial direction via a spacer 1, an outer race 3 arranged outside the inner race 2, and an inner race.
- a double-row rolling element 4 (tapered roller in the figure) rotatably interposed between the raceway surface 2 and the raceway surface of the outer ring 3 and the rolling elements 4 of each system IJ are kept at equal intervals in the circumferential direction Cage 5 is a main component. Since this bearing is used as an axle bearing for a railway vehicle, a housing 13 for mounting the railway vehicle is mounted on an upper portion of the outer diameter of the outer ring 3.
- An oil seal case 7 holding an oil seal 6 therein is fitted to the inner peripheral surfaces of both ends of the outer ring 3 described above, and oil draining members 8 slidingly contacting the oil seal 6 are attached to both outer sides of each inner ring 2.
- the front cover 9 is arranged at the shaft end, and the rear cover 10 is arranged on the opposite side of the front cover 9, and the front cover 9 is fastened to the axle 12 with bolts 11, so that the bearing is connected to the axle. It is fixed to 1 and 2.
- a convex portion 14 that protrudes in the radial direction is provided below the outer diameter of the outer race 3, and a rotation sensor 15 is attached to an end surface of the convex portion 14.
- the rotation sensor 15 is fixed to the projection 14 of the outer race 3 by two screws 16.
- This rotation sensor 15 For example, a reflective photoelectric switch or the like can be used, and an encoder 17 is provided on the outer peripheral end surface of the front cover 9 so as to face the light emitting and receiving unit.
- the rotation sensor 15 With the rotation sensor 15 attached to the outer ring 3 as described above, it is possible to measure the rotation speed of the inner ring 2 (axle 12), which is the rotating member, relative to the outer ring 3, which is the stationary member. Become. In this case, since the rotation sensor 15 is firmly attached to the outer ring 3 having high rigidity, the rotation sensor 15 can accurately measure the rotation speed of the bearing. In addition, since the rotation sensor 15 is attached to the lower portion of the outer diameter of the outer ring 3 to which the housing 13 is not attached, the housing 13 does not hinder the attachment of the rotation sensor 15.
