Abstract
A spindle motor is disclosed, wherein the spindle motor is formed at an outer periphery of a first protruder of a bearing housing having a gap relative to the inner periphery of the coupling hole of a base with a guide portion contacting an inner periphery of a coupling hole, whereby, the bearing housing is not moved on the base by the guide portion, and whereby the bearing housing is always coupled to a predetermined area of the base, such that when the base assembled with parts is coupled to the product, the parts are always positioned at a predetermined area of the product, thereby improving product reliability.
Claims13
A spindle motor comprising:
- a rotation shaft;
- a bearing rotatably supporting the rotation shaft;
- a bearing housing where the bearing is installed and the bearing housing formed with a first protruder being protrusively formed on one end of the bearing housing;
- and a base on which a coupling hole connected to the first protruder is formed, wherein the first protruder includes a guide portion whose region contacting an inner periphery of the coupling hole is slantedly formed.
A spindle motor comprising:
- a base on which a coupling hole is formed;
- a bearing housing having a first protruder inserted into the coupling hole through caulking and vertically installed on the base;
- a bearing fixed inside the bearing housing;
- a rotation shaft supportively and rotatably installed into the bearing;
- a rotor coupled to the rotation shaft to simultaneously rotate with the rotation shaft;
- and a stator disposed around the bearing housing to rotate the rotor, wherein the first protruder is formed at an outer periphery thereof with a guide portion that contacts an inner periphery of the coupling hole.
