Abstract
The utility model relates to a ceramic bearing transferred structure of fans, which is characterized in that a metal ring sleeve with a larger friction coefficient than the ceramic bearing is sleeve-arranged at one end of the ceramic bearing, the friction coefficient of the contact surface is increased by the embossing of the inner and the outer ring surfaces of the metal ring sleeve, and the metal ring sleeve and the fan are jointly inject-molded to be combined to reduce the loosing of the fan from the ceramic bearing.
Description
Technical field
The utility model relates to a kind of ceramic bearing adapter structure of fan, and the particularly a kind of bearing that is used for fan is a ceramic material.
Background technique
The fan that is used for the contour arithmetic element of microprocessor at present, cause is along with arithmetic speed day by day improves, traditional fan that utilizes metal bearing to make can not satisfy use, main cause is to be raise gradually by the temperature of radiator, and the deficiency in draught that fan provided, running speed is also fast inadequately, thereby cause the metal bearing life-span to shorten significantly, therefore, the existing bearing that adopts stupalith to make substitutes, and utilizes ceramic material own hard, and characteristic wear-resisting, heat resistanceheat resistant, and can increase substantially rotation speed of the fan, and then reach the purpose of enough heat radiations.
But, existing technician's very big problem of discovery in making test process of making ceramic bearing is demanded urgently improving, because general bearing is that mutual group is connected into type when fan is injected, but the smooth surface of ceramic bearing own, friction factor is extremely low, when fan when running up, being subjected to centrifugal force pulls, ceramic bearing breaks away from fan easily and forms skidding, and be to improve this situation, intimate engagement when having only the ceramic bearing of increasing skin friction to come with the fan injection, but the purpose of using stupalith originally is exactly because the high advantage of its hardness, that is to say, the embossing facility that are used in every metal at present for the basic performance of ceramic bearing not effect, even embossing achieves the goal reluctantly, but institute takes time and cost does not meet economic benefit.
Summary of the invention
Main purpose of the present utility model, be to solve the aforesaid drawbacks, avoid the existence of shortcoming, the utility model adopts original metal bearing easily and the advantage of fan combination, directly be arranged with the metal ring set of a friction factor greater than ceramic bearing at ceramic fan one end, in this metal ring set, the outer ring surface embossing increases the friction factor of surface of contact, can firmly combine when utilizing metal ring set outer ring surface with the common injection moulding of fan, and metal ring set inner ring surface is except that providing the friction tight power of tightening, also provide the frictional force of embossing to make the ceramic bearing difficult drop-off, and metal ring set of the present utility model is made and assembling is all quite simple and easy, and real for the technician of existing making fan is a big Gospel.
Relevant detailed description of the present utility model and technology contents, existing as follows with regard to accompanying drawings:
Description of drawings
Fig. 1 is a stereoscopic schematic representation of the present utility model;
Fig. 2 is a STRUCTURE DECOMPOSITION schematic representation of the present utility model;
Fig. 3 is a section combination schematic representation of the present utility model;
Fig. 4 is another an embodiment's of the present utility model schematic representation.
Embodiment
See also Fig. 1,2,3, be the utility model stereoscopic and STRUCTURE DECOMPOSITION schematic representation, as shown in the figure: the utility model is the adapter structure that is used for fan 10 and ceramic bearing 13, be arranged with the metal ring set 14 of a friction factor at these ceramic bearing 13 1 ends greater than ceramic bearing 13, wherein, the inner ring surface 141 of this metal ring set 14 utilizes the facility embossing to increase the friction factor of its inner ring surface 141, outer ring surface 142 also utilizes the facility embossing to increase the friction factor of its outer ring surface 142, and this metal ring set 14 provides one to tighten power with friction tight mode socket ceramic bearing 13, combine with fan 10 common injection mouldings by this metal ring set 14, reduce the come off purpose of fan 10 of ceramic bearing 13 and reach.
By can obviously finding out among Fig. 3, when fan 10 utilizes its upper magnetic ring 11 runnings, because metal ring set 14 is with friction tight mode socket ceramic bearing 13, perhaps shown in Figure 4, be to offer a short slot 143 as C type clasp mode at metal ring set 14, utilize the sheathed ceramic bearing 13 of anchor clamps again, these two kinds of modes all provide the tighten power of metal ring set 14 with ceramic bearing 13, and metal ring set 14 inner ring surfaces 141 fully embossing increase frictional force, therefore, ceramic bearing 13 will be difficult for deviating from from metal ring set 14, also not having skidding produces, again the ceramic bearing 13 of sheathed metal ring set 14 is put into the injection mould of fan 10, when fan 10 injection mouldings, fan 10 will have a winding protuberance 12 in order to winding ceramic bearing 13, since ceramic bearing 13 with 14 one-tenth fixedly connected relations of metal ring set, and metal ring set 14 itself can be undressed, the iron that surface friction coefficient is high, the copper metal, make is that the fan 10 of plastic material combines fully closely with metal ring set 14 originally, in addition, the utility model also utilizes the embossing technology to increase its friction factor at metal ring set 14 outer ring surfaces 142 equally, metal ring set 14 is run up at fan 10 more can not produce skidding down, and guarantee the quality of fan 10.
The above, it only is preferred embodiment of the present utility model, can not be in order to limit the scope that the utility model is implemented, i.e. equivalent substitutions and modifications of being done according to the utility model claim generally all should still belong in the scope that the utility model contains.
