摘要： A method for manufacturing a bearing mechanism used in an electric motor includes (a) inserting an annular member into a substantially cylindrical closed-bottom cup member to bring a first end portion of a shaft fitted to the annular member into contact with a thermoplastic resin member arranged on an inner bottom surface of the cup member, bringing the annular member into contact with the shaft in a direction leading from an opening of the cup member to a bottom portion of the cup member, and fixing the annular member to the cup member; and (b) deforming the resin member by externally heating the bottom portion of the cup member and applying a load acting toward the bottom portion on a second end portion of the shaft. Further, an electric motor includes a rotor unit, a stator unit, and the bearing mechanism manufactured by this method.

摘要： A thrust plate used in a fluid dynamic pressure bearing of the present invention includes a concave portion in which a lower end portion of a shaft is accommodated. The thrust plate is immersed in a lubricant, and is disposed between the lower end portion of the shaft and a bottom-portion upper surface of a bearing housing without being fixed to the bearing housing.Accordingly, the thrust plate radially moves in accordance with the position in which the lower end portion of the shaft is in contact with the concave portion of the thrust plate. As a result, the centers of the shaft and the thrust plate motor can be aligned satisfactorily.

摘要： A sleeve has a thrust dynamic pressure generating groove arrangement for generating a dynamic pressure in a thrust direction between another member and the sleeve. The sleeve is formed in the following manner. First, a mold is prepared which is provided with a portion corresponding to the thrust dynamic pressure generating groove arrangement. Injection molding is carried out by using this mold and material containing binders and metal particulates, thereby forming a work-in-process piece having the thrust dynamic pressure groove arrangement in a cavity of the mold. Then, binders in the work-in-process piece are removed by heating, and thereafter metal particulates in the work-in-process piece are sintered.

摘要： A hydrodynamic bearing device comprises a shaft bush having a substantially conical inclined dynamic pressure surface around the outer circumference thereof which is relatively rotatably inserted in a bearing sleeve having a substantially conical inclined dynamic pressure surface around the inner circumference thereof. A substantially conical inclined bearing space is created in the gap between the inclined dynamic pressure surfaces of the bearing sleeve and shaft bush. Lubricant fluid is filled inside the inclined bearing space. A proper dynamic pressure generating means is formed on at least one of the inclined dynamic pressure surfaces of the shaft bush and bearing sleeve. The lubricant fluid is pressurized by the dynamic pressure generating means to generate dynamic pressure, by which the shaft bush and the bearing sleeve are relatively elevated in the radial and thrust directions so that their rotations are supported in a non-contact manner. A fluid sealing portion is provided in the inclined bearing space to prevent the lubricant fluid from leaking outside of the inclined bearing space. A fluid pressurizing means is provided between the inclined bearing space and the fluid sealing portion to pressurize the lubricant fluid in the direction to push it toward the inside of the inclined bearing space.

摘要： A suitable the inner point is set on a vapor-liquid face of lubricating fluid formed in a composite capillary seal section that utilizes capillary force and rotational centrifugal force acted on the lubricating fluid. An inner peripheral surface of a ring-shaped portion is formed such that the minimum value R1 in radial-direction distances of the inner peripheral face of the ring-shaped portion becomes greater than a radial-direction distance R2 of the inner point (R1>R2). This can observe the inner point of the lubricating fluid from the immediately-above position, whereby the filling amount of the lubricating fluid can easily and surely be measured, thereby being capable of adjusting the filling amount of the lubricating fluid to a preset amount.

摘要： A hydrodynamic bearing apparatus for use in a spindle motor. The bearing includes at least two hydrodynamic bearing sections for supporting a rotary member with respect to a fixed member, a hydrodynamic pressure generating mechanism, a space between the two hydrodynamic bearing sections, a lubricant, two capillary sealing sections, and a lubricant reservoir. In the hydrodynamic bearing apparatus, the hydrodynamic pressure generating mechanism is positioned at the hydrodynamic bearing sections, and the capillary sealing section of the two capillary sealing sections has a space capacity which allows for an increased amount of lubricant. The lubricant is moved by a predetermined amount in one direction by a differential pressure generated at the hydrodynamic bearing sections when the rotary member rotates.

The core is constituted by laminating two cores, that is, a first core and a second core, which are different from each other in shape of a surface facing to a rotor magnet. At least a part of a cogging torque generated at the second core can be cancelled by a cogging torque generated at the first core.
