Problems solved by technology

But there are also some problems, such as: the oil deflecting ring is a powder sintered ring, which can only absorb the lubricating oil at the top of the oil bearing, and cannot recover the lubricating oil thrown out from the edge
In addition, the fan disclosed in the above patent does not provide a good installation method, and the working stability of the fan needs to be further improved

Abstract

The invention provides a fan mounting mechanism. The fan mounting mechanism comprises a mounting base, a magnetic sleeve assembly, a graphite separation blade, a stator core, an oil-containing bearing and a motor shaft, wherein the motor shaft is arranged in the oil-containing bearing, and can rotate relative to the bearing; one end of the motor shaft is fixed to a blade main body; the oil-containing bearing is nested in the stator core; the stator core is arranged on a circuit board; a limiting sleeve is arranged between the oil-containing bearing and the blade main body; the mounting base is provided with an accommodating hole; the magnetic sleeve assembly is arranged in the accommodating hole. By adopting the fan mounting mechanism, self-circulation of lubricating oil and further fixing of a fan are realized.

Description

technical field [0001] The invention relates to a mounting mechanism, in particular to a fan mounting mechanism. Background technique [0002] Axial fans are widely used in heat dissipation of machines such as laptops and refrigerators. In addition to having good low-noise characteristics, it also needs to be able to work stably for a long time. There are two main factors that affect the service life of the fan: the circulation effect of the lubricating oil and the smoothness of the fan when it is working. Patent No.: 200710077333.4 discloses a fan, the main improvement of which is to add an oil deflector ring above the oil bearing to realize the self-circulation of lubricating oil. But there are also some problems, such as: the oil deflecting ring is a powder sintered ring, which can only absorb the lubricating oil at the top of the oil bearing, and cannot recover the lubricating oil thrown out from the edge. In addition, the fan disclosed in the above patent does not pr...
