摘要： Disclosed is a fluid dynamic bearing device in which it is possible to prevent detachment of the shaft member reliably and at low cost without involving any increase in the device size. In a thrust bearing portion T, the lower end surface of the shaft member is held in contact with a thrust plate, and the shaft member is rotatably supported in the thrust direction. Protrusions extending radially inwards are provided on a sealing portion attached to an opening of the housing, and these protrusions are engaged with a small diameter portion formed on the outer peripheral surface of the shaft member, thereby preventing the shaft member from coming off.

摘要： The inner peripheral surface of the larger-outer-diameter portion 11a is pressed against the upper forming portion 20 of the sizing core rod 12, so that the bearing surface of a shape corresponding to the forming portion 20 is formed in the inner peripheral surface. As the upper punch 14a and the sizing core rod 12 are further moved in operative association with each other, the end of the smaller-outer-diameter portion 11b reaches the tapered portion 21b1 of the drawing portion 21b, so that it is subjected to a radially inwardly directed pressurizing force. Thereby, the inner peripheral surface of the smaller-outer-diameter portion 11b is pressed against the lower forming portion 20 of the sizing core rod 12, so that the bearing surface of a shape corresponding to the forming portion 20 is formed in the inner peripheral surface.
摘要翻译：大外径部分11a的内周表面被挤压在定型芯棒12的上部形成部分20上，使得在内周表面上形成与形成部分20相对应的形状的支承表面。当上冲头14a和上胶芯棒12彼此进一步移动时，较小外直径部分11b的端部到达拉伸部分21b的锥形部分21b1，使得它经受径向向内的加压力。由此，小外径部11b的内周面被压靠在定型芯棒12的下部形成部20上，使得与形成部20对应的形状的支承面形成在内周表面。

摘要： Fine particles (6) are retained by an electroformed portion (4) in a dispersed state, and the fine particles (6) exposed from an outer peripheral surface (4a2) of the electroformed portion (4) are molten so as to form micro projections (60) integrated with a resin portion (5). The micro projections (60) enters into fine-particle traces (4c) formed in the electroformed portion (4) to exert an anchor effect, to thereby increase a fixation force between the resin portion (5) and the electroformed portion (4).

摘要： A hub portion of a fluid dynamic bearing device is formed from a resin composition in which polyphenylene sulfide (PPS) is employed as a base resin and with which carbon fibers are mixed. In this manner, the wear resistance and the conductivity can be improved. Alternatively, both portions of a stationary body and a rotating body of the fluid dynamic bearing device which portions face to each other through a bearing gap are formed from a resin composition in which polyphenylene sulfide (PPS) is employed as the base resin. In this manner, excellent wear resistance can be obtained.

摘要： Two bearing bodies 1 each having a bearing surface 17 are force-fitted into a housing 7 which is opened at one end and closed at the other end thereof, and a shaft 2 (rotary shaft) is inserted in the bearing bodies 1, thereby forming two axially spaced porous oil-impregnated bearings A. The inner peripheral surfaces of the bearing bodies 1 and the oil leak preventing member 11 are formed with a plurality of inclined grooves (hydrodynamic-pressure-generating grooves 5 and air current producing grooves 12). A solid lubricating composition 3 composed of synthetic resin as a base material and oil as a lubricating component by blending lubricating oil or lubricating greases is disposed between the two bearing bodies 1.
