Принадлежит: SEAGATE TECHNOLOGY LLC

A fluid dynamic bearing motor and method are described, wherein motor components, including complex shaped motor components, are molded of plastic. The molding ensures form control and dimensional control thereby accomplishing design requirements, and eliminating or reducing component costs and component machining. The mold can be shaped to form various motor geometries, thereby eliminating the need for multiple component assembly and related assembly costs. In an aspect, a plastic integral motor hub is formed by injection molding. Alternatively, a plastic motor hub is affixed to a metal sleeve. In another aspect, fluid containment structures are molded into the motor component, reducing the number of components as compared with machined metal components. In a further aspect, bearing structures such as grooves are molded into the motor component, thereby eliminating processes such as electrochemical machining. In yet a further aspect, a plastic hub faces a thrustplate, reducing expensive sleeve machining.

A female shaft 16 B is fitted onto a male shaft in a state of interference, and by causing the male shaft 16 A to slide back-and-forth a specified number of times in the axial direction with respect to the female shaft 16 B while applying, for example, a load in a direction that bends the male shaft 16 A with respect to the female shaft 16 B, friction heat is generated between side surfaces 411 of grooves 41 in the female shaft 16 B and the coated section 61 , which heats the coated section 61 and causes the coated section 61 to expand along the entire length in the axial direction of teeth 51 of the male shaft 16 A. Therefore, the coated section 61 plastically deforms along the entire length in the axial direction of the teeth causing compressive strain to occur. By causing the male shaft 16 A to slide back-and-forth with respect to the female shaft 16 B in this state, the grooves 41 of the female shaft 16 B and the teeth 51 of the male shaft 16 A are uniformly in contact along the entire length in the axial direction, and thus sliding friction becomes constant along the entire length of the sliding range.

An elastic bush and an electric motor using the elastic bush are proposed. The elastic bush includes a bush body having in a central portion thereof a coupling hole into which a rotating shaft is inserted, a circular separation plate spaced apart from an end of the bush body in an extending direction of the rotating shaft and coming into close contact with a neighboring associated component, and a plurality of connecting legs each connected at both ends thereof to the bush body and the separation plate, and elastically deformed to vary a relative distance between the bush body and the separation plate. An entire length of the elastic bush is varied through elastic deformation. Therefore, a gap between two components located on both sides of the elastic bush, such as a front bush and an armature assembly, may be more effectively reduced.
