New description: [New technical field] This creation is about a stable structure of cooling fan operation, especially a fan stable structure that can effectively locate the center of the bearing and improve the lubrication effect. [Prior Art] According to the assembly mode of the general cooling fan, the shaft core is covered by the blade body to form a body, and then the metal motor casing and the magnetic strip are respectively accommodated in the body of the fan, and the motor is energized by the motor. The rotation of the fan blades is used to heat the information products. The centering of the axis is easy to shift during the injection molding process and when the magnets are assembled, causing the instability of the vibration when the fan is running. There is also noise. In addition, in order to provide lubrication for the rotation of the rotating shaft, the oil sleeve or oil groove is usually formed on the inner wall of the bearing to reduce the friction of the rotating shaft. However, the assembly of the fan bearing is not entirely in the same direction. It will also be reversed in response to the fan function of different products. When the bearing is reversed, it will easily leak the lubricating oil to the motor and cause damage to the fan. [New content] The purpose of this creation is to provide a fan running stable structure capable of effectively positioning the bearing center 3' and improving the lubrication effect; mainly comprising a cooling fan, a motor casing fixed in the cooling fan frame, and The motor casing is formed into a plastic bearing and a fan frame with a shaft center at the center. The self-lubricating engineering plastic bearing and the motor casing are integrated into one structure, and the motor casing can be easily positioned when combined with the inner frame of the cooling fan. The centering and verticality of the plastic bearing combination is also set on the axis that has been centered on the center, and the corresponding degree of centering is maintained to improve the smoothness and stability of the fan operation and reduce noise. In order to enhance the smooth operation efficiency of the cooling fan, the creation is particularly suitable for the combination of the motor casing and the inner frame of the cooling fan, and at the same time, an oil storage space is formed to enable the micro-oil release to reduce the friction of the rotating shaft in the plastic bearing, thereby enhancing the wind shape. Smooth operation and efficiency, and reduce the sound of _. [Embodiment] θ 1~Q 7 feathers, - motor casing 2, blade frame 3; wherein the blade i includes a frame 100 having a concave space 10 and a blade integrally protruding from the outer periphery of the frame The fairy is combined with the inner casing 2 for the motor casing 2; the motor (10) is - with the opening of a 2G and the towel of the gold g. 2 the central perforated inner edge of the secret structure 21G gift of the regular shot In the type, the bearing 22 is molded and integrated in the center of the metal casing 21 to form an integral body, and the micro-warping structure 210 absorbs the deformation generated during the injection molding process and the thermal deformation during the operation to make the structure of the plastic bearing 22 more The upper end of the plastic bearing 22 has an accommodating space 22 〇, and the central axis of the bottom of the accommodating space 220 penetrates through a shaft hole 23 to the lower end of the plastic bearing 22; and the accommodating space 22 is used for The positioning piece having the central through hole 241 and the plurality of oil storage groove holes 24 is accommodated (for example, when the second piece 24 is used to accommodate the shaft center in the shaft hole 23 of the plastic bearing 22, the blade 1 can be used with the blade 1 The clamping position is set in the accommodating space 22 〇; The inside of the space 22 is filled with lubricating oil in the oil reservoir hole 24 of the positioning piece 24, and is directly received in the fan blade 丨 space through the upper end surface of the motor casing 2, and is attached to the surface. 2 and the elasticity of the blade 1 is combined with the Malay 2 and the light cloth in the combination of the service towel, in addition to the plastic bearing 22 view 23 center degree take shape, but also the motor shell 2 "fan blade 1 The combined paste state space is used as the oil storage space, and the axial center 3G for the center of the fan blade frame 3 is inserted into the shaft hole of the human plastic bearing 22. When the shaft hole 23 of the 卩230 is used, the shaft center 3 () top card slot That is, the central perforation of the set position piece % is positioned by the positioning piece 24, and the oil storage slot holes 240 of the positioning piece 24 are communicated with the shaft center 30, and the lubricating oil pre-stored in the oil storage slot hole 24 provides the shaft. The heart 30 is used for lubrication (such as the fourth and fifth figures); and when the assembly is completed, when the shaft 30 penetrates the shaft hole 23, a compression space is formed to facilitate the armor assembly, so as not to generate a rebound force. Liu Tuqing's squad configuration can prevent lubricant from leaking to the motor and not in the forward or reverse direction. Damage to the fan motor & when the blade is directly above the 1st position (as shown in Figure 6), the centrifugal force generated by the operation of the blade 1 will cause the oil in the space of the plastic bearing to be split outward, and the shaft The lubrication of the outer wall of the heart 30 is limited due to a small amount, and it will stop flowing downward due to the upward suction generated by the fan blade operation, so that it does not flow to the motor for safety, and if the reverse configuration is used, the motor is located above, and the lubrication is performed. The oil does not flow to the motor, and thus protects the motor. This creation is a relatively flat and stable fan of the domain fan, and the other preferred embodiment formed by the double motor 2 structure of the seventh figure is mainly plastic. The joint surface of the bearing 4 covers the concave bottom surface of the motor casing 2, thereby forming the arc-side of the concave bottom surface of the motor casing 2 to form a flat abutting surface 40, and the arrangement of the magnetic strip 5 is flatly attached to prevent magnetic The deformation of the strip 5 produces a sentence that maintains the magnetic stripe. "• It is then integrated with the fan assembly, and the shaft is fixed in the plastic bearing. The inspection is transferred to the bearing hole of the traditional money purchase to improve the fan operating efficiency. According to the eighth embodiment, another embodiment of the motor casing of the present invention is mainly characterized in that the central casing of the motor casing 2 has a vertical flange 2〇〇, and the shaft is made by its own center degree and verticality. The heart 3〇 is positioned, and the plastic 2〇1 is used to reinforce the rotation axis d to touch the towel and the silkness, providing better operational stability.
