Embodiment Construction

[0018] see figure 1 , shows the cooling fan motor structure of the present invention.

[0019] The cooling fan motor structure includes a frame body 10 , a stator 22 , a seat body 40 and an oil-repelling collar 70 .

[0020] Wherein, a positioning seat 12 is provided in the middle of the frame body 10 , and a hollow bushing 13 extends vertically upward in the middle of the positioning seat 12 . The upper end of the bushing 13 has an end surface 14 and a middle hole 15 inside.

[0021] A rubber gasket 16 , a retaining ring 18 and a self-lubricating bearing 20 are arranged in the middle hole 15 of the shaft sleeve 13 .

[0022] The stator 22 is sleeved on the periphery of the shaft sleeve 13, and the stator 22 has a through hole 28, the inner diameter of the through hole 28 is smaller than the inner diameter of the hollow 15 of the shaft sleeve 13, and the through hole 28 The upper end is provided with an extending portion 24 extending inward.

[0023] The extension portion 2...

Abstract

A cooling fan motor structure comprises a frame, a stator, a seat and an oil retaining ferrule. A positioning seat is arranged in the middle of the frame, a hollow shaft sleeve extends in the middle of the positioning seat in a vertically upward manner, the upper end of the shaft sleeve is provided with an end face, a middle hole is formed inside the shaft sleeve, a stator sleeve is arranged on the periphery of the shaft sleeve, a through hole is formed in the stator, an extending portion which extends inwards is arranged at the upper end of the through hole, an inner ring and an outer ring extend downwards in the middle of the seat, a spindle is arranged in the inner ring in a sleeved manner, the oil retaining ferrule contains a first end and a second end, diameter of the first end is larger than that of the second end, the first end is closely matched with the inner wall of the outer ring and the outer wall of the inner ring of the seat, the second end extends into the through hole of the stator, and a seam is formed between the second end and the extending portion of the stator. Consequently, the cooling fan motor structure is simple in structure and convenient to use and can realize good lubricating effect.

Description

technical field [0001] The invention relates to a cooling fan motor structure. Background technique [0002] In the fan motor, due to the fast rotation speed of the fan, the lubrication performance of the motor shaft is required to be high. Existing fans often have problems such as abnormal noise and damage, which are all caused by poor lubrication. [0003] For this reason, in view of the above-mentioned defects, the designer of the present invention researches and designs a cooling fan motor structure to overcome the above-mentioned defects by concentrating on research and design, and integrating experience and achievements in related industries for many years. Contents of the invention [0004] The technical problem to be solved by the present invention is: due to the high rotation speed of the fan and high requirements on the lubrication performance of the motor shaft, the existing fans often have problems such as abnormal noise and damage, all of which are caused by p...
