9. The apparatus of claim 1, wherein the socket tool is selected from the group consisting of a socket wrench, an adjoining extension, a universal joint and a socket.
10. The apparatus of claim 1, the apparatus further comprising a seal disposed on the socket interface and forming a seal between the socket interface and the socket.
11. The apparatus of claim 1, the apparatus further comprising a diversion channel selected from the group consisting of a groove, a flume, flashing, corrugation and a deflecting shield.
12. The apparatus of claim 1, wherein the socket interface is magnetized.
13. A method for shield module comprising:
providing a shield having a maximum radius in the range of 5.7 to 10 centimeters (cm); and
providing a socket interface that connects a socket to a socket tool through the shield.
14. The method of claim 13, wherein the method further comprises diverting oil from a drain with the shield.
The claims below are in addition to those above.
All refrences to claim(s) which appear below refer to the numbering after this setence.
1. A spindle motor comprising:
a lower thrust member fixedly attached to a base member;
a shaft having a lower end portion coupled to the lower thrust member and an upper end portion provided with a flange portion;
a rotating member including a sleeve rotating based on the shaft; and
a fixed member including a fitting protrusion protruding upwardly in an axial direction and fitted into and fixed to a fixation groove recessed upwardly from a lower end of the shaft in the axial direction and a flange caught by a lower surface of the lower thrust member.
2. The spindle motor of claim 1, wherein the fitting protrusion is slidably inserted into the fixation groove.
3. The spindle motor of claim 2, wherein an adhesive is applied between an outer surface of the fitting protrusion and the fixation groove, such that the fitting protrusion and the fixation groove are bonded to each other.
4. The spindle motor of claim 1, wherein the fitting protrusion is at least partially press-fitted into the fixation groove.
5. The spindle motor of claim 1, wherein the fitting protrusion is screw-coupled to the fixation groove.
6. The spindle motor of claim 1, wherein a seating groove on which the flange is seated is provided in the lower surface of the lower thrust member.
7. The spindle motor of claim 1, wherein a coupling length between the lower thrust member and the shaft in the axial direction is 10 to 15% of a length of a bearing span formed between the shaft and the sleeve.
8. The spindle motor of claim 1, wherein a through hole is provided in the lower thrust member, such that the lower end portion of the shaft is fitted into the through hole.
9. The spindle motor of claim 8, wherein the shaft is slidably inserted into the through hole.
10. The spindle motor of claim 8, wherein the shaft is press-fitted into the through hole.
11. The spindle motor of claim 9, wherein an adhesive is interposed between the shaft and the lower thrust member.
12. The spindle motor of claim 10, wherein an adhesive is interposed between the shaft and the lower thrust member.
13. A hard disk drive comprising:
the spindle motor of claim 1, rotating a disk by power applied thereto through a substrate;
