Furthermore, the first partial section 201 is accommodated in the first accommodation space 111 and is surrounded and abutted by the flexible surrounding structure 3 so that the flexible surrounding structure 3 can pass through the first accommodation space 111. The space (or the step-like surrounding groove 100) is abutted on the first partial section 201 of the shaft body 20 in a limited manner. In addition, the second partial section 202 is connected to one end of the first partial section 201 and is accommodated in the second accommodation space 112, and the third partial section 203 is connected to the other end of the first partial section 201 and accommodated in Within the third accommodation space 113. In addition, the fourth partial section 204 is connected to the first The three-part section 203 is accommodated in the fourth accommodating space 114, and the fifth-part section 205 is connected to the fourth-part section 204 and is accommodated in the fifth accommodating space 115. Furthermore, the sixth partial section 206 is connected to the second partial section 202 and is exposed outside the bearing body 10, and the seventh partial section 207 is connected to the fifth partial section 205 and is exposed outside the bearing body 10.
值得一提的是，配合圖2、圖4以及圖5所示，軸承本體10具有一位於第一容置空間111內的第一圍繞狀內表面1001、一位於第二容置空間112內的第二圍繞狀內表面1002、一位於第三容置空間113內的第三圍繞狀內表面1003、一位於第四容置空間114內的第四圍繞狀內表面1004以及一位於第五容置空間115內的第五圍繞狀內表面1005。更進一步來說，第一圍繞狀內表面1001與第二圍繞狀內表面1002之間的第一間距H1會大於可撓性圍繞結構3被壓縮之前的一截面半徑r，並且第一圍繞狀內表面1001與第三圍繞狀內表面1003之間的第二間距H2會小於可撓性圍繞結構3被壓縮之前的一截面直徑d。 It is worth mentioning that, as shown in FIGS. 2, 4 and 5, the bearing body 10 has a first surrounding inner surface 1001 located in the first accommodation space 111, and a bearing body 10 located in the second accommodation space 112. A second surrounding inner surface 1002, a third surrounding inner surface 1003 located in the third accommodation space 113, a fourth surrounding inner surface 1004 located in the fourth accommodation space 114, and a fifth accommodation The fifth surrounding inner surface 1005 in the space 115. Furthermore, the first distance H1 between the first surrounding inner surface 1001 and the second surrounding inner surface 1002 will be greater than a cross-sectional radius r before the flexible surrounding structure 3 is compressed, and the first surrounding inner The second distance H2 between the surface 1001 and the third surrounding inner surface 1003 will be smaller than a cross-sectional diameter d before the flexible surrounding structure 3 is compressed.
舉例來說，第三圍繞狀內表面1003與第五圍繞狀內表面1005都可以是無溝槽的表面。另外，第二容置空間112的第二直徑D2可以從軸心入口100A朝第一容置空間111的方向漸漸縮小，而使得第二圍繞狀內表面1002也可以是具有斜面的錐狀表面，藉此以方便將可撓性圍繞結構3內嵌在段差式圍繞狀凹槽100內。 For example, both the third surrounding inner surface 1003 and the fifth surrounding inner surface 1005 may be groove-free surfaces. In addition, the second diameter D2 of the second accommodating space 112 may be gradually reduced from the axial center entrance 100A toward the first accommodating space 111, so that the second surrounding inner surface 1002 may also be a tapered surface having an inclined surface. This facilitates embedding the flexible surrounding structure 3 in the step-like surrounding groove 100.
藉此，配合圖2、圖4以及圖5所示，由於第一圍繞狀內表面1001與第二圍繞狀內表面1002之間的第一間距H1會大於可撓性圍繞結構3被壓縮之前的截面半徑r，所以當可撓性圍繞結構3置入第一容置空間111內(或是段差式圍繞狀凹槽100內)時，可撓性圍繞結構3將不易脫離第一容置空間111(或是段差式圍繞狀凹槽100)。另外，由於第一圍繞狀內表面1001與第三圍繞狀內表面1003之間的第二間距H2會小於可撓性圍繞結構3被壓縮之前的截面直徑d，所以當軸心本體20貫穿貫穿孔11且部分地容置在 貫穿孔11內時，可撓性圍繞結構3就能通過第一容置空間111(或是段差式圍繞狀凹槽100)的空間限位而圍繞地緊靠軸心本體20的第一部分區段201，以使得軸心本體20能夠得到有效的支撐效果，且可避免潤滑油從軸承本體10與軸心本體20之間洩漏而出，而達到防漏油與防塵的雙重效果。 Therefore, in accordance with FIG. 2, FIG. 4, and FIG. 5, since the first distance H1 between the first surrounding inner surface 1001 and the second surrounding inner surface 1002 will be larger than that before the flexible surrounding structure 3 is compressed. The cross-sectional radius r, so when the flexible surrounding structure 3 is placed in the first containing space 111 (or in the step-like surrounding groove 100), the flexible surrounding structure 3 will not easily leave the first containing space 111. (Or stepped surrounding groove 100). In addition, since the second distance H2 between the first surrounding inner surface 1001 and the third surrounding inner surface 1003 will be smaller than the cross-sectional diameter d before the flexible surrounding structure 3 is compressed, when the shaft body 20 penetrates the through hole 11 and partially housed in When penetrating the hole 11, the flexible surrounding structure 3 can be closely abutted against the first part of the shaft body 20 through the space limitation of the first receiving space 111 (or the step-like surrounding groove 100). 201, so that the shaft center body 20 can obtain an effective support effect, and the lubricant can be prevented from leaking from between the bearing body 10 and the shaft center body 20, thereby achieving the dual effects of preventing oil leakage and dust.
值得一提的是，配合圖2與圖4所示，由於可撓性圍繞結構3被容置在第一容置空間111內(或者是內嵌在段差式圍繞狀凹槽100內)，所以本發明就不需要額外再套設另外的O型環在第六部分區段206上，藉此以增加第六部分區段206的周圍區域的使用空間進而能夠有效降低本發明的風扇裝置Z及其軸承組件S的整體厚度。 It is worth mentioning that, as shown in FIG. 2 and FIG. 4, since the flexible surrounding structure 3 is accommodated in the first accommodation space 111 (or embedded in the step-like surrounding groove 100), The present invention does not need to additionally set another O-ring on the sixth partial section 206, thereby increasing the use space of the surrounding area of the sixth partial section 206, which can effectively reduce the fan device Z and The overall thickness of its bearing assembly S.

As shown in FIG. 7, the bearing body 10 may use only a plurality of first grooves 101 and omit the use of a plurality of second grooves 102, so the fifth surrounding inner surface 1005 may be a surface without grooves.
舉例來說，圖8為本發明其中一實施例所提供的軸承組件的第四種軸承結構的剖面示意圖。如圖8所示，軸承本體10可以只使用多個第二溝槽102而省略多個第一溝槽101的使用，所以第三圍繞狀內表面1003可以是無溝槽的表面。 For example, FIG. 8 is a schematic cross-sectional view of a fourth bearing structure of a bearing assembly according to an embodiment of the present invention. As shown in FIG. 8, the bearing body 10 may use only the plurality of second grooves 102 and omit the use of the plurality of first grooves 101.
