Abstract

A roller bearing seal assembly for supporting the drive rolls of a continuous casting machine including an angle ring forming a sealing gap and a lamellar ring seal between the angle ring and a bearing or bearing housing. The angle ring has an axially directed shank and a radially oriented shank mounted in either the outer ring of the bearing, or in the bearing housing in such a way that its axially oriented shank projects beyond the end surface of the roller bearing or housing. The lamellar ring seal is installed between the radially oriented shank of the angle ring and the lateral surface of the inner ring of the bearing. A rotary shaft lip seal is installed on the side of the angle ring facing the interior of the bearing. The axially oriented shank of the angle ring extends into a ring-shaped groove in a drive roll end surface opposite the end surface of the roller bearing or housing.

Claims

1. A roller bearing and seal assembly for supporting the drive rolls of a continuous casting machine including an angle ring forming a sealing gap and a lamellar ring seal between the angle ring and a bearing or bearing housing, comprising:

an angle ring having an axially directed shank and a radially oriented shank mounted in the outer ring of the bearing or in the bearing housing in such a way that its axially oriented shank projects beyond the end surface of the roller bearing or housing;

a lamellar ring seal installed between the radially oriented shank of the angle ring and the lateral surface of the inner ring of the bearing;

a rotary shaft lip seal installed on the side of the angle ring facing the interior of the bearing; and

said axially oriented shank of the angle ring extending into a ring-shaped groove in a drive roll end surface opposite the end surface of the roller bearing or housing.

2. The roller bearing and seal assembly of claim 1, further characterized in that the lamellar ring seal is mounted in a ring-shaped groove in the bore surface of the radially oriented shank of the angle ring, and rests on the lateral surface of the inner ring of the bearing.

3. The roller bearing seal assembly of claim 1, further characterized in that the bore surface of the radially oriented shank of the angle ring is opposite the lateral surface of the inner ring of the bearing and is separated from it by a short distance.

4. The roller bearing seal assembly of claim 1, further characterized in that the rotary shaft seal is mounted between the end surface of the angle ring facing the interior of the bearing and a shoulder in the bore of the outer ring of the bearing or of the housing.

5. The roller bearing seal assembly of claim 1, further characterized in that the angle ring and the rotary shaft seal are split in the axial direction.

6. The roller bearing seal assembly of claim 5, further characterized in that the angle ring has a flange on its peripheral surface, said flange engaging in a corresponding peripheral groove in the bore of the outer ring or housing.
