New description: [New technical field] This is a kind of bearing, especially a kind of bearing structure which can generate circulating oil supply between mandrel and bearing. [Prior Art] According to the conventional motor, the rotor can operate smoothly, mainly because the bearing shaft of the rotor and the seat body, the housing or the sleeve are pivotally arranged with bearings, and when the rotation is rotated, let The mandrel reduces energy loss due to friction. It is a key issue for the bearing of the hammer to rotate smoothly. The types of bearings can be roughly divided into ball bearings, linear bearings, oil-impregnated bearings, sleeve-type bearings, etc. In the operation of these bearings, different bearing applications are used depending on the rotor speed, so that when the rotor is rotating, Can meet the designer's requirements. The most commonly used bearings in the H-type fan are the oil-impregnated bearings and sleeve-type bearings mentioned above. A bearing is provided at the center of the bearing. The through-hole can be pivoted to the mandrel of the rotor. The bearing and the mandrel are filled with lubricating oil' to facilitate the smooth rotation of the mandrel in the bearing. Although the above-mentioned conventional bearings are filled with lubricating oil, the mandrel of the rotor is smoothly rotated in the bearing, but there is no structural design for the lubricating oil recovery cycle and the lubricating oil in these bearing designs. Therefore, when the mandrel of the rotor and the bearing run for a period of time, the mandrel and the bearing will be: gravity, centrifugal force and internal pressure, causing the lubricating oil in the bearing to be pulled out of the bearing due to the rotation of the mandrel, so that the lubricating oil is lost. Causes less and less lubricating oil in the bearing' and loses the lubrication function' even the phenomenon of dryness', which leads to: 5 M294157 The method rotates smoothly in the bearing, causing serious loss of the mandrel and bearing due to friction, and noise. occur. [New content] The main purpose of this creation is to solve the above-mentioned shortcomings and avoid the lack of existence. 'This creation redesigns the bearing and the mandrel, so that the bearing and the mandrel of the rotor have a cyclic oil supply design, so that the mandrel can be smoothed. Operation, so that the bearing and the shaft do not cause serious wear and noise problems. For the purpose of the above, the present invention is a structural improvement of a bearing, comprising: a mountain bearing having a central hole and at least a first-class channel, each of which has a capillary groove and a cross section communicating with the central hole The groove has a spiral ring groove which is connected with the capillary groove and the cross section. [Embodiment] The technical content and detailed description of the creation are as follows: See the following paragraphs: The second figure shows the bearing stereoscopic appearance of the first example of the creation and the bearing profile state diagram of the first figure. ^(4) is the bearing i, and the axis W has at least the flow path η. The two 11th extension has a capillary groove m and a slit 112 which communicate with the central hole 12. Please refer to "the third figure is ^^w" r/T. The shaft is slidably disposed in the sleeve 3 of the seat body, and a spindle 2 is pivotally connected to the central hole 12 of the 6 M294157 bearing 1. The collar of the spindle 2 is provided with a ring groove 21 communicating with the flow passage 11 . The ring groove 21 is formed by a spiral ring on the surface of the mandrel 2 (this ring groove can also be placed in the bearing ring) The inner wall of the core hole is described later in detail. When the mandrel 2 rotates, the lubricating oil in the bearing ring is pushed down along the spiral ring groove 21 of the mandrel 2 by the flow path slit 112. The oil flows out so that the lubricating oil is sucked into the capillary groove ui by the flow path u, and is again sucked into the bearing oil and the mandrel 2 by the capillary groove 111. Thus, when the bearing 1 is applied to an upright, horizontal or inclined position, the lubricating oil can be re-recovered by forced drainage due to the capillary phenomenon of the capillary groove 111, and the mandrel 2 and the bearing 1 are cyclically supplied. The oil state achieves the effect of making the mandrel 2 run more smoothly. Please refer to the fourth and fifth figures, which are the perspective exploded view of the bearing of the second embodiment of the present invention and the sectional view of the use state of the fourth figure. The bearing la of the present invention is provided with at least a first-class road ua. The bottom of the flow passage 11a is formed by a 112a which communicates with the central hole 12a, and a cover 4 is provided at the top end of the bearing la, and has a central hole 43 thereon, and the cover 4 has a majority with the bearing ratio. The projection 41 forms a gap (such as a capillary groove) 42 with the capillary state between the cover 4 and the bearing la. When the mandrel 2 rotates, the lubricating oil in the bearing ia is pushed down along the spiral ring groove 21 of the mandrel 2 and flows out through the slit U2a, so that the lubricating oil is sucked to the seal through the flow passage 11a. The gap 42 between the cover 4 and the bearing la is again sucked into the bearing ia by the gap 42. Thus, when the bearing la is applied to the upright, horizontal or inclined placement, the capillary phenomenon of the gap 42 can be M294157 applies gravity to re-recover the lubricating oil through forced diversion, which causes the mandrel 2 and the bearing la to circulate, which makes the mandrel 2 run more smoothly. Please refer to the sixth figure, which is a sectional view of the bearing of the third embodiment of the present invention. In this embodiment, the annular groove 13 is ring-shaped in the center hole 12 (or 12a) of the bearing 丨 (or 1&). On the inner wall, when the mandrel 2 rotates, the lubricating oil in the bearing 1 (or la) is pushed down along the annular groove a to flow out through the slit 112 (or 112a), so that the lubricating oil flows through the flow passage. Ua is sucked into the capillary groove 111 (42) and then sucked into the bearing or 匕) by the capillary groove iH (or 42), so that the bearing 1 (or la) can be applied to the upright, horizontal or inclined position At the time of release, the capillary can be overcome by the capillary phenomenon of the capillary groove 111 (or 42) to re-recover the lubricating oil by forced drainage, so that the mandrel 2 and the bearing 丨 (or la) are circulated to achieve the mandrel 2 Smoother operation. Please refer to the seventh and eighth figures, which are the three-dimensional appearance of the bearing of the fourth embodiment of the present invention and the state of use of the seventh figure. The bearing lb disclosed in this embodiment has at least a first-class bearing lb. a channel llb, a bottom portion of the flow path iib extending through the slot 1221), and a convex shaft 13b extending from the outer surface of the shaft ibb, and a gap gap 14b formed between the outer surface of the shaft i3b and the outer surface of the bearing After the gap 14b is in the bearing lb and the sleeve 3 group f, the falling gap 14b forms a capillary space with the inner wall of the sleeve 3, and the convex shaft 13b has a capillary groove mb, and the capillary groove mb is formed with the central hole 12b. In the communicating state, a spiral ring groove 15b is formed in the inner wall of the center hole 12b (the ring groove may also be disposed on the mandrel). When the mandrel 2 rotates, the lubricating oil of the bearing ratio is pushed down along the ring groove M294157 15b and is sucked into the flow channel by the slit groove 1121), so that the lubricating oil is sucked again through the flow path lib. In a capillary space formed by the drop gap 14b and the inner wall of the sleeve 3, the lubricating oil is again sucked into the capillary groove 111b by the capillary space, and then sucked into the center hole 125 by the capillary groove nib, so that the bearing is made When lb is applied to an upright, horizontal or inclined position, the lubricating force can be re-recovered by forced diversion due to multiple capillary phenomena, so that the mandrel 2 and the bearing lb are cycled to achieve the operation of the mandrel 2. For the smoother function, please refer to the "Ninth Diagram", which is a bearing profile state diagram of the fifth embodiment of the present invention. The bearing lc disclosed in this embodiment has a center hole 12c and a bearing. The capillary groove 111c and the slit groove n2c which communicate with the central hole 12c are formed. The sleeve 3 which is connected to the bearing ic has a flow passage 31 communicating with the capillary groove 111c and the slit H2c, and is further described above. a spiral is formed on the inner wall of the center hole 12c.
