Abstract
A tilting pad journal bearing manufacturing method includes a first process and a second process. In the first process, a pivot fitting hole is formed on a convex curved outer circumferential surface of the tilting pad. The pivot fitting hole is recessed from the outer circumferential surface toward an inner circumferential surface and has an inner diameter smaller than an outer diameter of the distal end portion of the pivot. In the second process, a concave portion is formed on the concave curved inner circumferential surface of the tilting pad by attaching the distal end portion of the pivot to the pivot fitting hole by interference-fitting.
