摘要： PROBLEM TO BE SOLVED: To solve a problem that, although there are a method of narrowing down a gap between a sleeve and a thrust member and a method of employing a cross-sectional shape of a thrust dynamic pressure pattern raking up a lubricant more efficiently in order to increase the dynamic pressure of a thrust dynamic pressure generation part to increase rigidity of a rotary device, the thrust dynamic pressure pattern formed by plastic working such as pressing generates deformation of the shape of protrusions and variation in the height of the protrusions.
SOLUTION: The thrust dynamic pressure pattern is marked on a rotary member or fixed member set on a rest table 501. A pressure for marking is applied to a member to be marked in a cycle of applying and releasing the pressure, and a supplemental force for keeping the member to be marked still is separately applied. According to the present embodiment, the rotary device can be produced that narrows down a bearing gap and improves the efficiency of raking up the lubricant to increase the dynamic pressure by reducing the deformation of the shape of the protrusions of the thrust dynamic pressure pattern and the variation in the height of the protrusions when forming the thrust dynamic pressure pattern in a method of producing the rotary device.
