Description
本發明係關於一種定位構造，尤其是一種軸承定位構造。 The invention relates to a positioning structure, in particular to a bearing positioning structure.
本發明係關於一種馬達，尤其是一種具軸承定位構造之馬達。 The invention relates to a motor, in particular to a motor with a bearing positioning structure.
請參照第1圖，其係一種習知的馬達9，該習知的馬達9具有一殼座91、一軸承組件92、一定子93及一轉子94。該殼座91具有一容置空間911；該軸承組件92具有一第一軸承921及一第二軸承922，該第一軸承921及該第二軸承922固定於該容置空間911並形成上下相對；該定子93係設置於該容置空間911；該轉子94具有一轉軸941及一永久磁鐵942，該第一軸承921及該第二軸承922係緊配結合於該轉軸941外周面，使該轉軸941與該軸承組件92之內環可轉動地設置於該容置空間911中。藉此，可輸入電流至該定子93，使該定子93驅動該轉子94旋轉作動。類似於該習知的馬達9的一實施例已揭露於中華民國公告第I539726號「馬達及其軸承組件」專利案當中。 Please refer to FIG. 1, which is a conventional motor 9. The conventional motor 9 includes a housing 91, a bearing assembly 92, a stator 93, and a rotor 94. The housing seat 91 has an accommodation space 911; the bearing assembly 92 has a first bearing 921 and a second bearing 922, and the first bearing 921 and the second bearing 922 are fixed to the accommodation space 911 and form opposite sides. The stator 93 is disposed in the accommodation space 911; the rotor 94 has a rotating shaft 941 and a permanent magnet 942; the first bearing 921 and the second bearing 922 are tightly coupled to the outer peripheral surface of the rotating shaft 941, so that the The rotating shaft 941 and the inner ring of the bearing assembly 92 are rotatably disposed in the accommodation space 911. Thereby, a current can be input to the stator 93, so that the stator 93 drives the rotor 94 to rotate. An embodiment of the motor 9 similar to the conventional one has been disclosed in the Republic of China Publication No. I539726 “Motor and its bearing assembly” patent.
然而，在該習知的馬達9中，該轉軸941必須與該軸承組件92之軸孔形成緊配合，以確保該轉軸941與該軸承組件92之內環能夠平穩地同速轉動。但，當該軸承組件92緊配結合於該轉軸941外周時，倘若該軸承組件92與該轉軸941其中一個受外力影響而震動，由於該轉軸941 與該軸承組件92一般均為金屬之硬材質製成，因此，容易使震動的力量傳遞，使該軸承組件92與該轉軸941之其中另一個也震動，進而使該轉軸941與該軸承組件92之軸孔壁因震動發生摩擦而受損，同時使該馬達9運轉時因該轉軸941與該軸承組件92震動而產生噪音，嚴重者更會影響該馬達9之性能及使用壽命。 However, in the conventional motor 9, the rotating shaft 941 must form a tight fit with the shaft hole of the bearing assembly 92 to ensure that the rotating shaft 941 and the inner ring of the bearing assembly 92 can rotate smoothly at the same speed. However, when the bearing assembly 92 is tightly coupled to the outer periphery of the rotating shaft 941, if one of the bearing assembly 92 and the rotating shaft 941 is affected by an external force and vibrates, since the rotating shaft 941 The bearing assembly 92 and the bearing assembly 92 are generally made of metal hard material. Therefore, it is easy to transmit the force of vibration, so that the other one of the bearing assembly 92 and the rotating shaft 941 also vibrates, so that the rotating shaft 941 and the bearing assembly 92 The shaft hole wall is damaged due to vibration and friction. At the same time, when the motor 9 runs, the shaft 941 and the bearing assembly 92 are vibrated to generate noise. In severe cases, the performance and service life of the motor 9 will be affected.
有鑑於此，習知的馬達確實仍有加以改善之必要。 In view of this, the conventional motor still needs to be improved.
