Abstract

PURPOSE: To obtain a high accuracy split bearing by merging machined split ring by welding, splitting the welded part after machining them so as to circularize the matching shape after splitting.
CONSTITUTION: The end surface of two hoop steels is defined preliminarily a desired split shape, pressing them to form a semi-circular shape in such a manner that an accurate circular form may be obtained when matching a semi-circular split rings 14. The matching surface of the semi-circular split rings 14 is welded 15. They are heat treated and finished in a specified outer and inner diameter dimensions of the bearing race after heat treating and grinding, and applying split pressure to the welded portion 15. This enables to split before deforming the split portion of the bearing race 13, allowing the split portion of the bearing race 13 to split before deformation and the matching shape after split to obtain the true circular shape.
