Problems solved by technology

[0002] Axial flow fans are widely used in ventilation and cooling of telecommunications, electrical appliances and other equipment. The bearing structure of the existing axial flow fans is generally composed of bearing housings, bearings and oil rings. During the die-casting process, it was found that the motor rotor and stator of the axial flow fans The gap between them is small and difficult to control. In use, there are often problems such as concentricity and verticality deviation between the motor rotor and the bearing. However, the reason is found to be poor lubrication due to lack of oil or less oil in the motor bearing. Over time, the phenomenon of jamming between the stator and the rotor caused by the burning of the motor
Thus affecting the service life of the motor, which in turn affects the ventilation and cooling of electrical equipment and communication equipment

Embodiment Construction

[0006] The present invention will be further described below in conjunction with accompanying drawing:

[0007] A kind of motor bearing of the present invention (as attached figure 1 , 2 , 3), composed of bearing housing 1, bearing 2 and oil ring 3, 4, its characteristics: bearing 2 is composed of bearing 21 and bearing 22 and at least one oil storage area 5 is arranged therebetween.

[0008] One embodiment, described motor bearing (as attached Figure 4 Shown), its characteristic: bearing 2 side is provided with an oil filling hole 6.

[0009] In another embodiment, the motor bearing (as attached Figure 5 Shown), its feature: bearing 21 lower ends and bearing 22 sockets.

[0010] The motor bearing of the present invention is characterized in that the oil seals 31 and 41 are single-lip mechanical oil seals.

[0011] In a preferred embodiment of the present invention, the motor bearing described above is characterized in that the bearing 21 and the bearing 22 are made of ...

Abstract

The bearing for motor is composed of bearing seat, bearing and upper and lower grease seals. Characters are that the original bearing is divided so that at least one oil storage region is setup at middle. Lubricating oil or grease is contained inside bearing. Thus, oil content in bearing is raised from 18% to 32% so as to prolong service life of motor in axial fan about 1.5 times.

Description

Technical field: [0001] The invention relates to a motor bearing, in particular to a motor bearing structure suitable for an axial flow fan. Background technique: [0002] Axial flow fans are widely used in ventilation and cooling of telecommunications, electrical appliances and other equipment. The bearing structure of the existing axial flow fans is generally composed of bearing housings, bearings and oil rings. During the die-casting process, it was found that the motor rotor and stator of the axial flow fans The gap between them is small and difficult to control. In use, there are often problems such as concentricity and verticality deviation between the motor rotor and the bearing. However, the reason is found to be poor lubrication due to lack of oil or less oil in the motor bearing. Over time, it will cause jamming between the stator and the rotor, which will cause the motor to burn out. As a result, the service life of the motor is affected, which in turn affects th...
