Problems solved by technology

[0004] As mentioned above, since the covering member 302 can only provide axial blocking, and also due to the interference between the sleeve 21 and the covering member 302, the inner diameters of the bearing 301 and the covering member 302 are easily reduced, resulting in contact with the rotating shaft. 101 worries
In addition, when the covering member 302 has a bearing torsion resistance by dispensing, it is also easy to vary due to materials or operating environments.

Embodiment Construction

[0035] The motor and its bearing structure according to preferred embodiments of the present invention will be described below with reference to the relevant drawings, wherein the same elements will be described with the same reference symbols.

[0036] Please refer to figure 2 and image 3 As shown, the motor 4 according to the preferred embodiment of the present invention includes a rotor structure 40 , a stator structure 50 and a bearing structure 60 .

[0037] The rotor structure 40 includes a hub 401 and a shaft 402 , and the shaft 402 is connected to the hub 401 . Such as figure 2 As shown, the rotating shaft 402 is embedded in the hub 401 . In addition, the rotating shaft 402 and the hub 401 can also be integrally formed, that is, the rotating shaft 402 and the hub 401 form a single body.

[0038] As mentioned above, the inner surface of the hub 401 is sequentially fixed with a magnetically conductive shell 403 and a magnet 404 . Wherein, the magnetically conduct...

Abstract

A bearing structure, which fits on a rotating shaft, includes a bearing and a cover. Wherein, the bearing fits on the rotating shaft, the covering part abuts against the bearing and covers at least a part of one end of the bearing, the covering part has a turning part, and the turning part has a groove.

Description

technical field [0001] The invention relates to a motor and its bearing structure, in particular to a motor and its bearing structure capable of overcoming components and assembly errors thereof. Background technique [0002] Motors have been widely used in electronic equipment. With the miniaturization trend of electronic equipment, motors also tend to be miniaturized and designed for high-speed operation. Therefore, how to reduce shaking and noise during high-speed operation is one of the important issues. [0003] Such as figure 1 As shown, a conventional electric machine 1 includes a rotor structure 10 , a stator structure 20 and a bearing structure 30 . The stator structure 20 drives the rotor structure 10 to rotate, and the rotating shaft 101 of the rotor structure 10 is axially set in the shaft hole 201 formed by the sleeve 21 of the stator structure 20 . The bearing structure 30 has a bearing 301 and a cover 302 . The bearing 301 is placed in the sleeve 21 and fit...
