Abstract

1.청구범위에 기재된 발명이 속한 기술분야1. Technical field to which the invention described in the claims belongs

본 발명은 하드디스크 드라이브의 데이타 저장매체인 디스크를 스핀들 모터에 고정시키기 위한 장치에 관한것이다.The present invention relates to an apparatus for fixing a disk, which is a data storage medium of a hard disk drive, to a spindle motor.

2.발명이 해결하려고 하는 기술적 과제2. Technical Challenges to be Solved by the Invention

본 발명은 디스크의 고정부 응력분포를 고르게 유지할 수 있으면서 단단한 고정을 이루는 디스크 고정장치를 제공하는데 있다.Disclosure of Invention Technical Problem [8] The present invention is to provide a disk fixing apparatus capable of uniformly maintaining the stationary stress distribution of a disk while firmly fixing the disk.

3.발명의 해결방법의 요지3. The point of the solution of the invention

본 발명은 통상의 디스크 고정장치에 있어, 스핀들모터의 허브상에 여러개의 고정홈을 형성하고, 허브의 중심에 나사구멍을 형성하며, 또한 클램프는 상기 고정홈에 끼워지도록 하는 테이퍼진 돌기를 형성하고, 클램프 중앙에 나사구멍을 형성하여, 상기 돌기와 1개 나사체결만으로 디스크를 고정시킨다.The present invention relates to a conventional disk fixing apparatus in which a plurality of fixing grooves are formed on a hub of a spindle motor and a screw hole is formed at the center of the hub and a clamp is formed to form a tapered projection A screw hole is formed in the center of the clamp, and the disk is fixed only by screwing the projection and the one screw.

4.발명의 중요한 용도4. Important Uses of the Invention

본 발명에 따른 디스크 고정장치는 한번에 체결을 해줌으로써 고정시 디스크의 치우침이나 어긋남을 줄일수 있고, 또한 체결토오크를 디스크 체결 부위에 균일하게 가져갈 수 있게 됨에 따라 디스크의 휨 또는 비틀림등을 방지하게 되는 잇점이 있다.The disk fastening device according to the present invention can reduce the deviation and misalignment of the disk when fastened by tightening the disk fastening unit at once, and also can prevent the disk from being warped or twisted as the fastening torque can be uniformly carried to the disk fastening site There is an advantage.
