Sealing arrangement
View Patent ↗The invention relates to a sealing arrangement that seals at least one radial intermediate space between at least one inner bearing ring and at least one outer bearing ring. Said sealing arrangement comprises at least one first support that supports at least one elastic seal and a second support which supports at least one encoder located outside the intermediate space. The encoder is radially oriented towards at least one sensor that is disposed above the encoder in a radially outward direction.
1. A sealing arrangement which seals at least one radial interspace between an outer lateral surface of at least one inner bearing ring and an inner lateral surface of at least one outer bearing ring, the radial interspace being a hollow region bounded radially by the inner lateral surface of the outer bearing ring and bounded axially by an imaginary plane which is oriented perpendicularly to the bearing axis and extends from the end surface of the outer bearing ring, the sealing arrangement, comprising:
at least a first support being at least partially rotationally fixed on an outer lateral surface of the outer bearing ring;
at least one elastic seal fixed to the first support; and
a second support having at least one encoder, which is orientated radially outwardly, arranged outside the interspace;
wherein the encoder engages around the inner bearing ring, and the encoder is covered fully at least in a radial direction and at least partially in an axial direction by means of a covering element, the covering element being rotationally fixed on one of the bearing rings and rotatable relative to the encoder, and
wherein neither the encoder, nor the sensor penetrate into the interspace, the first support being formed integrally with the covering element, and the covering element being interposed between the encoder and the sensor.
2. The sealing arrangement as claimed in claim 1 , wherein the seal abuts the inner ring.
3. The sealing arrangement as claimed in claim 1 , wherein the covering element at least partially covers the seal.
4. The sealing arrangement as claimed in claim 1 , wherein the first support is made of sheet metal.
5. The sealing arrangement as claimed in claim 4 , wherein the covering element is fixed on a radially outer surface section of the outer bearing ring.
6. The sealing arrangement as claimed in claim 5 , wherein, starting from the outer bearing ring, the covering element first of all extends axially away from the outer bearing ring and radially beyond the encoder, and covers the encoder in the radial direction in the process, in that the covering element then extends radially inward and covers the encoder and the interspace in the axial direction in the process, and in that the covering element, finally, extends axially in the direction of rolling bodies and accommodates the seal.
7. The sealing arrangement as claimed in claim 4 , wherein the covering element is fixed on an inner surface of the outer bearing ring.
