Detailed Description
Example (b): the utility model provides a fan integral type bearing structure, including axle center 1, flabellum 2, magnet 3, integral type bearing 4, circuit board 5, fan frame 6 and coil assembly 7, there is integral type bearing 4 fixed mounting that self-lubricating material made on fan frame 6 base 61, the inboard blind hole that forms of integral type bearing 4, axle center 1 can be pivoted insert locate in this blind hole, the motor housing 21 fixed mounting of flabellum 2 is in axle center 1 tip, magnet 3 fixed mounting is on flabellum 2, the integral type bearing 4 outside is located to coil assembly 7 fixed cover, and coil assembly 7 is just right with magnet 3 position, circuit board 5 fixed mounting is on fan frame 6's base 61.
Through adopting the material preparation integral type bearing 4 that has self-lubricating function, axle center 1 direct mount is in integral type bearing 4, and axle center 1 rotates smoothly under integral type bearing 4 lubricating function, and integral type bearing 4 direct mount has avoided the use of axle sleeve, solid fixed ring and wear pad on the base 61 of fan frame 6, has simplified fan inner structure, has simplified the equipment process, is favorable to reducing the fan height.
The integrated bearing 4 is of a self-lubricating plastic integrated structure. But may be made of other materials with self-lubricating properties, such as graphite materials, etc., which are equivalent structures that can be easily conceived by those skilled in the art based on the present patent.
The integrated bearing 4 and the base 61 of the fan frame 6 are of an integrated structure.
The base 61 of the fan frame 6 and the integrated bearing 4 are of a split structure, and the integrated bearing 4 is fixedly connected with the base 61 of the fan frame 6 in a mode of in-mold injection molding, gluing or connecting piece connection.
