Production method of rotating device having thrust dynamic pressure generating site on which a thrust pressure pattern is formed and rotating device produced by said production method |
摘要 |
A thrust dynamic pressure pattern is marked on a rotating member or fixed member set on a rest table. 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, a rotating device can be provided that narrows down a bearing gap and improves the efficiency of raking up a lubricant so as to increase the dynamic pressure by reducing the deformation of the shape of the protrusions of a 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 a rotating device. |
