Method for optimizing a grooved bearing pattern on a bearing surface of a fluid dynamic bearing for the purpose of improving the bearing properties and an appropriate grooved bearing pattern

摘要

The invention relates to a method for optimizing a grooved bearing pattern on a bearing surface of a fluid dynamic bearing for the purpose of improving the bearing properties as well as an appropriately designed grooved bearing pattern, the grooved bearing pattern having a defined length, width and depth, and the bearing surface being moveable with respect to another associated bearing surface in at least one direction of movement, having the following steps:;selection of a bearing property to be improved, optimization of the geometry of the grooved bearing pattern in respect of the bearing property to be improved by adjusting one or more of the following parameters of the grooved bearing pattern:depth, width, length, angle with respect to direction of movement of the bearing surface or its normal, contour, geometry of the transition to adjacent surfaces.
