METHOD OF MANUFACTURING A DYNAMIC GROOVE BEARING BY MEANS OF A METAL-REMOVING TOOL, AND DATA STORAGE UNIT PROVIDED WITH SUCH A DYNAMIC GROOVE BEARING |
摘要 |
A method of manufacturing a dynamic groove bearing having parts rotatable relative to one another. The bearing parts include cooperating bearing surfaces and a pattern of grooves by means of a metal-removing tool. A first bearing part is fastened to a rotatable support of a machine tool, which is rotated in a constant direction. The tool is periodically displaced relative to the first bearing part parallel to a direction transverse to the bearing surface of the first bearing part by a positioning device with a frequency which is determined by a product of a rotation frequency of the support and a number of grooves on the bearing surface of the first bearing part. The tool is periodically displaced in a sinusoidal movement and the positioning device may include a piezoelectric actuator (95). A data storage unit including dynamic groove bearings is also provided. |
