Embodiment Construction

[0057] A fan, a motor and its bearing structure according to a preferred embodiment of the present invention will be described below with reference to related drawings, wherein the same components will be denoted by the same reference numerals.

[0058] See Figure 3. As shown in FIG. 3 , the bearing structure 2 of the first preferred embodiment of the present invention cooperates with the rotating shaft 31 , and the bearing structure 2 is arranged in the shaft tube 32 . When the bearing structure 2 is applied to a motor, the rotating shaft 31 can be the rotating shaft of the rotor structure in the motor, and the shaft tube 32 can be the shaft tube of the stator structure in the motor.

[0059] In this embodiment, the shaft tube 32 is integrally formed, that is, the shaft tube 32 is a single body. In addition, the bottom of the shaft tube 32 has a wear-resistant structure 321 (such as a wear-resistant sheet). Of course, in other embodiments, the shaft tube 32 can also be a sh...

Abstract

The present invention discloses one kind of bearing structure matching with a rotation shaft and set inside a shaft tube. The bearing structure includes one self-oiling bearing and one cylindrical sealing structure, the self-oiling bearing has one shaft hole for the rotation shaft to be set inside, and the cylindrical sealing structure covers the top and at least one part of the side wall of the self-oiling bearing and has one central through hole for holding the rotation shaft. The bearing structure has no leakage of lubricant oil, and the motor and the fan with the bearing structure has long service life.

Description

technical field [0001] The invention relates to a fan, a motor and its bearing structure, in particular to a fan, a motor and its bearing structure for preventing oil leakage. Background technique [0002] Nowadays, many devices (such as fans) use motors to achieve the function of transmission. Therefore, the quality of the motor has a considerable proportion to the quality of the whole device. If the motor is not working stably, it will inevitably affect the operation of the whole device. It is one of the important parts that affect the quality of the motor. [0003] Most of the existing motors use ball bearings, but the cost of the ball bearings is relatively high, they cannot resist external shocks, and cannot provide sufficient lubrication when the motor is running at a high speed. Therefore, in the prior art, oil bearings are mostly used to replace ball bearings. However, when assembling the oil-impregnated bearing on the shaft tube, it is necessary to apply sufficien...
