Patent JP-2001173655-A (JP)
Title: Journal bearing
Inventor: ARIKABE TAKEO
IPC: F16C32/06
Filed: 1999-12-17
Abstract: PROBLEM TO BE SOLVED: To provide a journal bearing having a large load carrying capacity and a low vibration. SOLUTION: A plurality of recesses 11 are disposed in a helical tooth form in a multi-recess type hydrostatic bearing 1. Each recess 11 is formed in a belt-shaped area slanting with respect to the generating line of a curvature in the inner wall of the hydrostatic bearing 1. Accordingly an inner wall area in which the load carrying capacity is small is evenly distributed in a central axis direction as it circumferentially rotates, thereby reducing a vibration due to the rotational constituent of a load applied to the hydrostatic bearing 1. When a recess 31 of dogleg shape is formed, a thrust load is not generated in a hydrostatic bearing 3.
