Abstract

A bearing rotatably supporting a shaft of a rotating body immersed in a molten-metal-plating bath, comprising at least two partially cylindrical ceramic bearing members each having a sliding surface coming into sliding contact with the shaft and end surfaces directly or indirectly connected to the sliding surface; and a holding member comprising a movement-restricting member arranged with a recess, in which at least two bearing members being circumferentially arranged with their one-side end surfaces opposing via a gap, the movement-restricting member abutting the other-side end surfaces of the bearing members for restricting the circumferential movement of the bearing members; at least one bearing member being circumferentially movable to or away from the other bearing member or members in at least two bearing members, such that the one-side end surfaces opposing via the gap come into contact or are separated from each other.

First claim

What is claimed is:

1. A bearing rotatably supporting a shaft of a rotating body immersed in a molten-metal-plating bath, comprising
at least two partially cylindrical ceramic bearing members each having a sliding surface coming into sliding contact with said shaft and end surfaces directly or indirectly connected to said sliding surface; and
a holding member comprising a movement-restricting member arranged with a recess, in which the at least two bearing members being circumferentially arranged with their one-side end surfaces opposing via a gap, said movement-restricting member abutting the other-side end surfaces of the bearing members for restricting the circumferential movement of the bearing members;
at least one bearing member being circumferentially movable to or away from the at least one other bearing member in the at least two bearing members, such that the one-side end surfaces opposing via said gap come into contact or are separated from each other.

2. The bearing according to claim 1 , wherein said gap crosses a centerline of said sliding surfaces when said centerline is viewed through said gap.

3. The bearing according to claim 1 , wherein said movement-restricting member has circumferentially projecting curved end surfaces abutting the other-side end surfaces of said bearing members.

4. The bearing according to claim 3 , wherein the other-side end surfaces of said bearing members, or the end surfaces of said movement-restricting member opposing the other-side end surfaces of said bearing members are provided with radially extending grooves.

5. The bearing according to claim 3 , wherein said movement-restricting member has circumferentially extending grooves communicating with said recess.
