Patent number: 9033580Abstract: The fluid dynamic bearing system has at, least one stationary part, and at least one rotating part that is supported rotatable about a rotational axis with respect to the stationary part. A bearing gap filled with bearing fluid is formed between mutually opposing surfaces of the stationary and of the rotating part. The bearing system includes at least one fluid dynamic radial bearing and at least one fluid dynamic axial bearing that are disposed along sections of the bearing gap. In one aspect of the invention, an annular sealing gap for sealing open ends of the bearing gap has one end connected to the bearing gap and one end connected to an annular reservoir, the outside radius of the reservoir measured from the rotational axis being larger than the outside radius of the sealing gap.Type: GrantFiled: December 3, 2013Date of Patent: May 19, 2015Assignee: MINEBEA CO., LTD.Inventors: Thomas Fuss, Martin Engesser, Atsushi Yanagawa, Werner Schmid, Carsten Etling

Publication number: 20100124387Abstract: The fluid dynamic bearing system has at least one stationary part, and at least one rotating part that is supported rotatable about a rotational axis with respect to the stationary part. A bearing gap filled with bearing fluid is formed between mutually opposing surfaces of the stationary and of the rotating part. The bearing system comprises at least one fluid dynamic radial bearing and at least one fluid dynamic axial bearing that are disposed along sections of the bearing gap. Moreover, sealing means for sealing the open ends of the bearing gap are provided. According to the invention, one of the sealing means comprises an annular sealing gap that has one end connected to the bearing gap and one end connected to an annular reservoir, the outside radius of the reservoir measured from the rotational axis being larger than the outside radius of the sealing gap.Type: ApplicationFiled: November 17, 2009Publication date: May 20, 2010Inventors: Thomas Fuss, Martin Engesser, Atsushi Yanagawa, Werner Schmid, Carsten Etling

Patent number: 7305759Abstract: In order to improve a device for the manufacture of a shaft assembly for a hydrodynamic bearing by pressing a shaft into a fit bore in a bearing disk, comprising a first pressing tool and a further pressing tool, in such a way that enables high accuracy to be achieved when the shaft is pressed into the bearing disk, with the lowest possible cost and effort in setting up the press, it is proposed that a shaft receiving portion which receives and guides the shaft aligned exactly to a central axis is associated with the first pressing tool, that a bearing disk receiving portion which receives and guides the bearing disk with a flat surface aligned exactly perpendicular to an axis is associated with the first pressing tool, and that for the pressfitting process, the first pressing tool acts on the shaft or the bearing disk by means of a first pressing element and a second pressing tool acts on the bearing disk or the shaft by means of a second pressing element.Type: GrantFiled: September 8, 2004Date of Patent: December 11, 2007Assignee: Minebea Co., Ltd.Inventor: Carsten Etling

Patent number: 7127939Abstract: To provide a measuring method on an electric motor with a rotor and a stator for determining the fly height and/or axial play, the rotor being mounted, and in particular fluid-mounted, on the stator, with which method the axial position of the rotor in relation to the stator can be determined with high levels of accuracy and reproducibility, it is provided that the electric motor is operated at a defined measuring speed, at which the rotor is in a specific axial position in relation to the stator, with this relative axial position being determined in that the rotor is brought in a defined manner, with the motor at a standstill, into a first stop position in relation to the stator, in that the rotor is brought in a defined manner, with the motor at a standstill, into a second stop position in relation to the stator, lying opposite the first stop position, and in that the relative axial position between the rotor and the stator is respectively measured in the two stop positions.Type: GrantFiled: April 7, 2004Date of Patent: October 31, 2006Assignee: Minetea Co., Ltd.Inventors: Norbert Irmer, Carsten Etling, Guido Schmid

Publication number: 20050060875Abstract: In order to create a device for the manufacture of a shaft assembly for a hydrodynamic bearing by pressing the shaft into a fit bore in the bearing disk, the device comprising a first pressing tool accommodating the shaft and a second pressing tool accommodating the bearing disk, in which the said disadvantages can be remedied to a great extent so that particularly one-sided “touching” and the resulting “seizing” hardly ever take place, leading to a considerable reduction in the percentage of rejected parts, it is proposed that the second pressing tool has a supporting member carried by the base member and accommodating the bearing disk that is to be pressed and that the supporting member is supported with respect to the base member in a radial direction to a central axis of the pressing tools by means of a media cushion formed from a medium, the supporting member floating on this media cushion and its movement in this radial direction being restricted.Type: ApplicationFiled: August 16, 2004Publication date: March 24, 2005Applicant: Minebea Co., Ltd.Inventors: Carsten Etling, Eduard Hudec
