Description of the new type: [Technical field to which the new type belongs] This creative department is a kind of dynamic pressure hybrid bearing device, which refers to a type of dynamic pressure that directly opens in the bearing _ along the diameter. It extends in the side and is curved in the side. A groove is generated, so that the slippery medium flows smoothly, and the air is not stagnant. Stay in it without any noise generator. [Previous technology] According to the press, bearings are a type of device that is used on rotating parts to support, reduce friction, and bear loads, such as spindle motors. With the advancement of technology, the relative parts are getting smaller and more precise ', but the relative requirements for bearing accuracy are getting higher and higher. Generally speaking, the most common requirements for precision bearings are ball bearings. Bearings, however, have some problems, including inadequate noise and large turning accuracy, and excessive miniaturization costs, which cannot meet the requirements of small size and precision. In order to meet the above requirements, and further reduce the friction of rotation, fluid bearings have also been introduced, not only with precision, low noise, and strong shock resistance. There are two types of fluid bearings, static pressure and dynamic pressure fluid bearings. Static pressure bearings are normally a fluid lubricating medium inside the bearing. When rotating, you can use the pressure of the fluid to support the thinner. Moving the side domain, Luming returns to the correct position; but because there is a large amount of fluid lubricating medium inside the bearing under normal conditions, it is not suitable for general small and precise rotation # age. Lai bearing has a slight reliance on the bearing material, and the groove ⑽ has a lubricating medium (because it is a fine groove, the amount of lubricating medium is quite small). When the shaft rotates, the groove is full. Meeting ^: Arrive, break up-New Zealand, Saki axis is supported at the center of the towel. Please refer to FIG. 1 'It is a motor applied to a fan. The motor has a motor base ⑽ handle up to the base 100 is provided with an upwardly extending bearing sleeve 11 〇, the bearing sleeve 穿 is sleeved with a bearing 120 As shown in FIG. 2, the bearing 120 has a shaft hole ⑵, and the wall surface around the shaft hole 121 is provided with a dynamic pressure generating groove 122 arranged similar to a fish bone and extending along the obtained direction. The dynamic pressure 5 M259867 produces a groove m and has a "herringbone" shape that gradually inwardly condenses from both ends. Between the groups that generate grooves, there are several escape holes around the shaft hole 121 in the shape of _.且, and the bearing training set is surrounded by a-motor stator 13 〇, the motor stator ⑽ is sleeved with-a motor rotor ⑽, the motor rotor 140 is provided with a fan around the other, the motor rotor _ is provided with- A shaft center 143 'is sleeved in the shaft hole 且 and a magnetic core 2 opposite to the motor stator 13 is provided. Although this device structure can use dynamic pressure generating grooves 122 to slide through the shaft hole 使用 cap during use f produces a butterfly, and further generates dynamic pressure to support and maintain the shaft center 143 at a central position. Because of the relationship between dynamic pressure and pressure, when the axis 143 is just started, the pressure has not yet been established, so it will be grinded and the iso-dynamic pressure generating groove 122 will extend straight and make the two hearts smooth. When the mass is moving, it will encounter the dynamic pressure generating groove 122 i against the vertical tangent edge of the mass, and cannot smoothly flow into its staggered place, and a small part of the compilation is retained on the dragon generating groove 122 _, and Because the dynamic pressure generating groove 122 is staggered at only one point, the lubricating medium flowing into it cannot be stored at all, resulting in the loss of the lubricating medium. [New content] Outline of creation: The creator of this creation has implemented _ in view of the manufacturing of dynamic pressure bearings. Therefore, it is aimed at the crux of the problem, and began to seek pure improvement, make up for its shortcomings, and seek to scale— After a number of researches, analyses, and designs, the dynamic pressure bearing device of this creation was finally completed. The purpose of this creation is to provide a dynamic pressure bearing device, which is a device that is used on rotating machinery to support, reduce miscellaneous loads and withstand chaotic loads, such as on the motor spindle of a computer fan. 'The device is provided with a shaft shaft, and the bearing is provided with a shaft hole penetrating therethrough. The shaft hole is provided with a plurality of neatly arranged dynamic pressure generating grooves extending radially along the shaft, and the dynamic pressure generating grooves Let the media containing fluid moisturizing π 'and the secretion groove be provided with _ axially extending bases, and the two ends of these bases are respectively connected to M259867-the sides that extend outward and extend, and these sides are curved. In this way, when the sleeve in the bearing rotates, the fluid perfused in the dynamic pressure generating groove will be pulled, and will flow from the side to the base and be concentrated in the base to form a slight bulge, and press against the axis. Make the shaft rotate smoothly, and because the side is curved, the lubricating medium will not be blocked from flowing completely into the base, and there will be no staying on the side, so the line of the bearing towel will not be affected. The quality of the branch of science Bearing 'and then there will be no noise of. The re-purpose of this creation is to provide a kind of dynamic bearing device, whose base length of the moving groove is determined by the viscosity of the lubricating medium. Another purpose of this creation is to provide a kind of _-type bearing device, a fixed part of the plane of which can be opened along the hole diameter of the shaft and has a ring-shaped escape hole, which can separate the interior of the bearing into two To several sections. [Embodiment] Please refer to Figures 3, 4, 5, and 6 for reference. This creation is a crane-type bearing device, which is a kind of application on the machine, which can reduce the county's money to bear the load. The device, for example, is applied to a fan motor. Please refer to FIG. 1. The motor has a motor base pair. The motor base ⑽ is provided with an upwardly extending bearing sleeve 110, and the bearing sleeve 11 is surrounded by a motor. The stator, the motor stator 130 is provided with a motor rotor 14o, and the fan rotor 14 is surrounded by fan blades 14. The motor rotor 140 is provided with a shaft center 143, and the motor rotor 140 is opposite to the motor stator 13o. 1 magnet. In addition, the bearing sleeve Π0 has a bearing 10 through the sleeve. The bearing 10 is provided with a hole 11 penetrating through it, and the shaft hole 11 is a barrel shape (such as As shown in the figure), a certain degree of inclination is generated. The shaft hole 11 is provided with a plurality of dynamic pressure generating grooves 12 extending in the radial direction of the shaft and arranged in a regular manner. The dynamic pressure generating grooves 12 contain a fluid lubricating medium (not shown in the figure). (Shown in Figure 4), and the dynamic pressure generating grooves 12 are respectively provided with a base 121 extending in the axial direction. In this implementation, M259867 is divided into signs A and P (as shown in Figure 5). ), And the length of these bases 121 is adjusted according to the viscous production of the medium. Two ends of the bases 121 are connected to an outwardly extending side 22, respectively. There is a certain angle between the side Qiu and the base 121. This embodiment is marked as κ and L, respectively. The angles of the K & L are less than 90 degrees, and the side portions 122 are curved. Therefore, when the axis 143 turns in the bearing 10, When moving, the fluid perfused in the dynamic pressure generating groove 12 will be pulled by the centrifugal force, and will flow from the side 122 to the base ⑵, and Concentrated on the base 121 and pressing slightly against the shaft center 143, the shaft center 143 rotates smoothly, and because the side 122 is curved, the lubricating medium will not be blocked from flowing completely into the base 完全. There will be no stagnation in Qing 122, and the air of the 1G towel will not be hindered by the lubricating medium. It will smoothly pass through the bearing 10 and will not stay in the bearing 10. This will allow the fluid to flow into each # when rotating. The pressure of the base 121 is average, which will not cause the shaft center 143 to tilt and cause friction with the bearing 10, and thus no noise will be generated. Furthermore, when the fluid flows in the generation groove 12, the shaft hole u can be oriented. The inner curved and inclined shape can block the fluid in flow, making it difficult for the fluid to be thrown out from both ends of the shaft hole u. Please refer to FIG. 4 and FIG. 5, around the shaft hole u is provided with an escape hole 13 extending in a ring shape along the shaft hole u. The escape hole 13 can separate the dynamic pressure generating groove 12 into two to Several parts, in addition, the base 121 of the dynamic pressure generating groove 12 may extend to both sides until the side 122 is reduced to a very short length (such as labeled A ′ in FIG. 6). · The above-mentioned embodiment of this case 'is only used to illustrate one of the feasible embodiments of this creation. For those who are familiar with this skill, various equivalent variations of its detailed shapes can be made, but they should be included in this creation. Within the spirit and scope.
