Description
Technical field
The present invention relates to is a kind of plastic packaging bearing arrangement, belongs to the technical field of bearing structure.
Background technique
In the prior art, existing oil-impregnated bearing commonly used adopts copper base or iron-base powder metallurgy material, and through powder metallurgical technique sintering and compression and moulding, material internal is covered with a large amount of cellular capillary gaps after the moulding, kind of lubricant storage can be received in these spaces, for the lubricated for a long time usefulness of bearing.This type of oil-impregnated bearing is installed in the pivoting support occasion that should not add oiling agent once more after the product assembling usually, must store enough oiling agents to prolong service life so bearing is inner.As shown in Figure 1, oil-impregnated bearing A1 is the spherical shape bearing of powdered metallurgical material among the figure, and the centre is provided with the through hole that cooperates with axle, can store enough oiling agents in order to make its inside, this bearing needs bigger oil-containing volume, contain asphalt felt A4 surround oil-impregnated bearing A1 around.In existing commonly used oil-impregnated bearing device, with the i.e. front cover A2 riveted fixing formation bearing chamber cavity among the figure of gland A5 and electric machine casing.Hold spherical powder metallurgy oil-impregnated bearing A1 in the bearing chamber cavity, pressing metallurgical oil-impregnated bearing A1 sphere as the compression spring A 3 of support shape, and by the elastic reaction of compression spring A 3 oil-impregnated bearing A1 is made axial elasticity and oppress, make its sphere fit tightly the inner ball surface of housing front cover A2, the location of having finished spherical oil-impregnated bearing A1.The rotary freedom of the spherical oil-impregnated bearing A1 in back, location can be adjusted automatically, thereby adjusts the amount of deflection of correcting axle automatically.The Location accuracy of this structure is subjected to the restriction of riveted joint precision between casing front cover A2 and the gland A5 and two s' machining accuracy, and coaxial accuracy is relatively poor, thereby causes the service behaviour conformity of oil-impregnated bearing in motor poor.And, unlubricated dose of locking device in the existing oil-impregnated bearing fixed structure commonly used, lubricant oil in service overflows loss easily from oil-impregnated bearing, and even dry, makes bearing bearing performance variation, shortens the machine run life-span.
Summary of the invention
The present invention seeks to for a kind of plastic packaging bearing arrangement is provided, this kind plastic packaging bearing arrangement can improve the Location accuracy to oil-impregnated bearing, the oil reserve of increase oil-impregnated bearing.
Plastic packaging bearing arrangement of the present invention is by the following technical solutions:
Plastic packaging bearing arrangement, its structural feature is: comprise plastic base, oil-impregnated bearing, the pedestal end face is provided with attachment hole, is provided with an inner chamber that is complementary with oil-impregnated bearing in the pedestal; Described internal chamber wall is provided with the groove of placing the immersion oil felt, and the immersion oil felt is placed in the described groove; Oil-impregnated bearing places in the described inner chamber, and the axis hole in described attachment hole and the oil-impregnated bearing is communicated with.
The technological scheme of plastic packaging bearing arrangement of the present invention, can also take following measure:
Aforesaid pedestal is made of bearing support and lubricating cup, and bearing support and lubricating cup link into an integrated entity.
Aforesaid pedestal is made of upper and lower symmetrical two-part, the one-body molded or process connection back formation one of described two-part.
Aforesaid groove is a circular groove, and the axis hole axial direction in the axial direction of circular groove and the oil-impregnated bearing is on same straight line.
Also establish the oiling aperture on the aforesaid pedestal, the oiling aperture is communicated with described groove.
Aforesaid oil-impregnated bearing) is spheroidal.
Aforesaid material is that main raw material constitutes by ABS, PC, PP plastic materials.
Aforesaid pedestal profile is cylindrical or cube.
The present invention has following outstanding effect:
1, owing to is provided with a chamber that is complementary with the oil-impregnated bearing profile in the pedestal of the present invention, this chamber can provide high Location accuracy to oil-impregnated bearing, make oil-impregnated bearing have flexibly rotating shaft deflection and correct the adjustment performance automatically, rotation dead point, vibration when effectively preventing the rotating shaft running, improve the service behaviour of oil-impregnated bearing, also helped stablizing its service behaviour.Noise when plastic materials formation pedestal can effectively reduce the rotating shaft running in addition.
2, because the chamber wall in the pedestal of the present invention is provided with the groove of placing the immersion oil felt, the immersion oil felt is placed in the described groove.The immersion oil felt can be laid in abundant oiling agent to replenish the lubricated of bearing.And groove is by the outer surface of oil-impregnated bearing sealing, makes outside the immersion oil felt can not be directly exposed to, effectively prevented oiling agent to external leakage, can prolong the working life of bearing element, thereby prolonged the working life of oil-impregnated bearing.
3, the present invention's assembling is finished and can be become a self-contained unit, is easily installed in the motor casing or other all suitable places that this class bearing is installed.
4, also establish the oiling aperture on the pedestal of the present invention, the oiling aperture is communicated with described groove, when the immersion oil felt in the pedestal does not have oil, and can be by oiling aperture make-up oil, and then with Sealing sealing oiling aperture, can further prolong the working life of bearing element.
5, pedestal of the present invention can use the fire retardant plastic material manufacturing, as plastic materialss such as ABS, PC, can reduce cost.
6, production craft step of the present invention is simple, and the component of base part can once injection moulding.Utilize ultrasonic welding process to assemble, it is easier to make part assemble, encapsulate.
