Abstract
The motor bearing aims at providing the improved structure of the motor bearing to prevent leakage and prolong the service life of an axial fan motor. The motor bearing of the utility model comprises a bearing base 1, a bearing 2 and at least one oil storage area 3. The utility model is characterized in that a bushing 4 is arranged between the peripheral side of the oil storage area 3 and the bearing base 1. The bushing 4 is made of materials with the same coefficient of heat expansion as the materials of the bearing 2. In this way, the oil content of the bearing is kept at about 32 percent and the service life of the motor is prolonged by one and a half times.
Description
Technical field:
The utility model relates to motor bearings, refers to a kind of improvement of motor bearings structure of suitable axial-flow blower especially.
Background technique:
Axial-flow blower is widely used in the aeration-cooling of equipment such as telecommunications, electrical equipment, the bearing structure of existing axial-flow blower generally is made up of bearing support and bearing and scraper ring, problems such as concentricity and perpendicularity deviation in use usually appear existing between rotor and the bearing, but trace it to its cause, discovery causes owing to motor bearings oil starvation or few oil lubricate not good generation friction.Though through improving,, produce seepage as ZL 2,005 2 0040991.2 motor bearingss, cause the phenomenon that produces situations such as blocking the evil spirit between the rotor and cause burn-down of electric motor in the course of time owing to still there is deficiency in it on the coupling of structure and material.Thereby influence the working life of motor, and then impact for electrical equipment and the aeration-cooling of communications equipment.
Summary of the invention:
A kind of motor bearings of the present utility model, its purpose are to reduce and have oil starvation or few oil between rotor and the bearing and lubricated not good generation friction, prolonging Axial-flow fan motor working life, and propose a kind of improvement of motor bearings structure.A kind of motor bearings of the present utility model comprises that bearing support 1 and bearing 2 and at least one reserve 3 constitute, and its characteristics are provided with a lining 4 between reserve 3 cylindrical sides and bearing support 1.Lining 4 adopts the material with bearing 2 same coefficient of thermal expansion.The oil content that keeps bearing like this is about 32%, thereby the working life that prolongs motor is near 1.5 times.
Description of drawings:
Fig. 1 is the motor bearings structure schematic representation of prior art;
Fig. 2 is an embodiment's of the utility model a structural representation.
Embodiment:
The utility model will be further described below in conjunction with accompanying drawing:
A kind of motor bearings (as shown in Figure 1) comprises by bearing support 1 and bearing 2 and at least one reserve 3 and constituting.Its characteristics are provided with a lining 4 between reserve 3 cylindrical sides and bearing support 1.
Preferred embodiment of the utility model, described motor bearings, its characteristics: lining 4 adopts the material with bearing 2 same coefficient of thermal expansion, makes as Cu alloy material.
In sum, that a kind of motor bearings of the present utility model has is simple in structure, processing is easy, the characteristics that cost is low, former powder metallurgy oil-impregnated bearing is being cut apart and be provided with betwixt on the basis of mode structure of at least one reserve, for avoiding seepage, prolong Axial-flow fan motor working life, and propose a kind of improvement of motor bearings structure.Its characteristics are provided with a lining 4 between reserve 3 cylindrical sides and bearing support 1.Lining 4 adopts the material with bearing 2 same coefficient of thermal expansion.The oil content that keeps bearing like this about 32%, thereby the working life that prolongs motor near 1.5 times, electric equipment and the aeration-cooling technology material guarantee that provides of communications equipment are provided.
Claims (2)
1. a motor bearings comprises bearing support (1), bearing (2) and at least one reserve (3), it is characterized in that: between reserve (3) cylindrical side and bearing support (1) lining (4) is set.
2. motor bearings as claimed in claim 1 is characterized in that: lining (4) adopts the material with bearing (2) same coefficient of thermal expansion.
