Abstract
The invention concerns a roller arrangement for a product to be coated in a molten metal bath, having a roller (1) which rotates in the metal bath and is retained at the ends rotatably on support arms (2) by way of rolling bearings (4), the rolling bearings (4) each being arranged in a bearing housing (5) sealed with respect to the metal bath (M), which is characterized in that in order to seal the bearing housing (5) with respect to the roller (1), sealing surfaces (15, 16) extending transversely to the roller axis (X) are configured [on a radially projecting shoulder (14) of the roller (1)] and on the bearing housing (5), and are retained under pressure against one another or against an interposed seal element (20).

A roller arrangement for a product to be coated in a molten metal bath, comprising a roller (1) which rotates in the metal bath and is retained at the ends rotatably on support arms (2) by way of rolling bearings (4), the rolling bearings (4) each being arranged in a bearing housing (5) sealed with respect to the metal bath (M), characterized in that in order to seal the bearing housing (5) with respect to the roller (1), sealing surfaces (15, 16) extending transversely to the roller axis (X) are configured on a radially projecting shoulder (14) of the roller (1) and on an inner surface of the bearing housing (5), and are retained under pressure against one another or against an interposed seal element (20).
A roller arrangement for use in a molten metal bath, comprising:
- first and second support arms;
- first and second sealed bearing housings connected to each of said first and second support arms;
- and
- a roller having first and second ends rotatably supported on rolling bearings in said first and second sealed bearing housings, said roller being immersible in a molten metal bath, and said roller first end including a radially projecting shoulder extending transversely to an axis of the roller;
- wherein said shoulder engages said bearing housing to substantially prevent the molten metal from entering said bearing housing.
The roller arrangement of 18 including means for biasing said shoulder against said bearing housing.
A roller arrangement for use in a molten metal bath, comprising:
- first and second support arms;
- first and second sealed bearing housings operably connected to each of said first and second support arms;
- a roller having first and second ends rotatably supported by rolling bearings in said first and second sealed bearing housings, said roller being immersible in a molten metal bath, and said roller first end including a radially projecting shoulder extending transverse to an axis of the roller;
- and
- a seal element mounted between said shoulder and said bearing housing;
- wherein said seal element engages said shoulder and said bearing housing to substantially prevent the molten metal from entering said bearing housing.
