Abstract: A bearing unit is provided which includes a shaft (51) to support rotatably, radial bearing (55) to support the shaft (51) circumferentially, a thrust bearing (66) to support the shaft (51) in the direction of thrusting, and a housing (56) having the radial bearing (55) and thrust bearing (66) disposed therein and in which a viscous fluid (57) is filled. The housing (56) has a sealed structure except for a shaft insertion hole (65) formed therein and through which the shaft 51 is introduced. Between the outer surface of the shaft (51) and the inner surface of the shaft insertion hole (65), there is defined a gap (69) having a sufficient width to prevent the viscous fluid (57) filled in the housing (56) from leaking out of the latter. The housing (56) is formed as a one-piece structure by molding a synthetic resin.

Abstract: A bearing for the blade assembly of the cooling fan, the bearing is made of the plastic steel material having an integrally formed cylindrical hollow body and outward extended large diameter seat. The seat bottom has a recess with screw thread cut along the inside wall. The bottom recess will receive a powerful magnet and a shield cap to cover. The hollow cylindrical body is a long accommodating cavity and extends upward to form a plurality of claws, each claw has a project point. The rotor shaft of the blade assembly will enter the accommodating cavity. The rotor shaft has a round groove to hold the project points of the claws in place. The rotor shaft is further attracted by the power magnet in the bottom recess so the rotor shaft is always kept along vertical center line, rotates in balance to achieve a stable floating rotation.

Abstract: The material of the wall inside a hole in a housing is squeezed toward the center of the using a staking tool with a diameter larger than that of the hole. The material necessary for forming a locking section can be obtained from only a small part of the entire area of the wall of the hole. The amount of material necessary for the entire process is secured and the material is pressed so as to contact with an end face of the outer race using the staking tool, forming the locking section. Accordingly, the locking section provides sufficient strength. Also, since only the small part of the entire area of the wall is necessary as described above, there is no decrease in strength or deformation as to the thin housing.

Abstract: A race for a bearing, which is mountable to a mount, has an annular bearing surface with a center axis defining an axis of rotation for the bearing and mutually perpendicular radial and transverse directions relative thereto. The race also has a radial wall that is adapted for mounting the race to the mount in a manner such that a bearing transfer load is transferred between the mount and the race in the transverse direction and the race bearing surface maintains its substantially annular shape independently of a load applied to the mount causing distortion of the mount when the race is mounted to the mount and the mount is loaded.

Abstract: A locking device and its assemblage are provided for confining an object such as a shaft of a motor. The locking device is used to confine the shaft having an end with a recess portion having a defining surface to prevent the shaft from being displaced in an axial direction. The locking device is a geometrically closed-loop body having an opening, and having a flexibility so that the shaft will pass through the opening and the end of the shaft will thus be confined by the locking device while the force disappears. The locking device is free from contact with the recess portion of the shaft when the shaft is spinning. A simple process can be used to assemble and disassemble the locking assemblage.
