Abstract
The coating device (10) for coating a metal band or strip (12, 12′) in a melted metal mass (14 ) comprises a shaft (16, 18) rotatably supported in the melted metal mass (14) by a slide bearing (261, 262) is formed by a bearing housing (32) and an open bearing shell (34) held therein, with two bearing surfaces (36) . Between the two bearing surfaces (36), the bearing shell (34) comprises a deformation zone (40) with a deformation element (44) . With high radial forces of the shaft occurring, the two bearing shell halves (381, 382) are slightly spread. The flexible deformation zone ensures that the two bearing shell halves remain interconnected and resist breaking in this area.
Claims8
A coating device for coating a metal band in a melted metal mass, comprising:
- a shaft, rotatably supported in the melted metal mass by a slide bearing, for guiding the metal band,
- the slide bearing being formed by a bearing housing and an open bearing shell held therein, the bearing shell comprising:
- exactly two bearing surfaces,
- the two bearing surfaces having a straight configuration in cross section,
- the two bearing surfaces being inclined to each other at an angle of about 130°,
- a deformation element which allows distortions of the bearing surfaces relative to each other, the deformation element being mounted between the two bearing surfaces,
- the bearing housing defining:
- a segment-like recess into which the bearing shell is inserted.
A coating device for coating a metal band in a melted metal mass, comprising:
- a shaft, rotatably supported in the melted metal mass by a slide bearing, for guiding the metal band,
- the slide bearing being formed by a bearing housing which defines a segment-like recess and an open beating shell received in the bearing housing segment-like recess, the bearing shell including:
- bearing surfaces, wherein the bearing surfaces consist of first and second bearing surfaces which are inclined to each other at an angle of about 130°, each bearing surface having a straight configuration in cross section and defining a line of contact with the shaft,
- a continuous radial gap formed in the bearing shell between the first and second bearing surfaces, and
- a deformation element is arranged in the gap between the first and second bearing surfaces.
An apparatus for coating a metal strip with a coating metal, the apparatus comprising:
- a pair of slide bearings, each defining a bore;
- a roller over which the metal strip passes disposed within a melted mass of the coating metal, the roller including journals at each end, each journal being rotatably received in a corresponding one of the slide bearing bores;
- first and second bearing elements disposed within each slide bearing bore in frictional engagement with one of the journals;
- and
- a resilient deformation element mounted between and in engagement with the first and second bearing elements of each slide bearing to provide a deformation zone between the bearing elements to protect the bearing elements against breakage.
A coating device for coating a metal band in a melted metal mass at a temperature of 400°C.–1000°C. comprising:
- a shaft for guiding the metal band, the shaft being rotatably supported in the melted metal mass by a slide bearing,
- the slide bearing including:
- a bearing housing.
- a plurality of bearing surfaces each having a cross-section in a straight configuration and being received in corresponding recesses of the bearing housing with the bearing surfaces being inclined to each other at an angle of about 130°, and
- a graphite sheet mounted between two adjacent bearing surfaces.
