Abstract
The utility model relates to a three-layer composite self-lubricating bearing of aluminum base alloy. The utility model forms a shaft sleeve shape. The surface of an aluminum base alloy base plate is combined with a spherical bronze powder layer. The surface of the spherical bronze powder layer is coated with antifriction and wear-resistance materials which mainly use polytetrafluoroethylene. The utility model has the advantages of light weight, difficult corrosion, self lubrication and high combination strength.
Description
Affiliated technical field
The utility model belongs to the bearing group in international Patent classificating number, i.e. F16C, particularly self oiling bearing.
Background technique
Known three-layer composite self-lubricating bearing draws West Asia company to be formulated by Britain's lattice.It is matrix with the steel plate, and sintering has spherical bronze bisque in the above, auxilliary again antifriction, the wear-resistant material layer that rolls based on teflon in surface.Make sleeve-like with this three-layer composite self-lubricating material webs, be called for short the DU bearing.This series products great advantage is selflubricating, but the matrix easy-to-rust, quality is heavy, can not be suitable for lightweight operating mode occasion.Existing No. 02295349.3 patent of our company, be on the acieral sticker based on two layers of composite bearing of the wearing layer of teflon, there is its aluminum matrix alloy to be difficult for the characteristics of corrosion, light weight, but aluminum substrate and wearing layer easily peel off, adhesive strength is undesirable, causes bearing reliability decrease in service.
The model utility content
The purpose of this utility model is to provide a kind of selflubricating, light weight, and matrix is difficult for the bearing of corrosion, composite bed adhesive strength height and rapid heat dissipation.
It is as follows to disclose new technological scheme: a kind of acieral three-layer composite self-lubricating bearing, be sleeve-like, it is characterized in that the acieral substrate above be combined with spherical bronze bisque, the surface of this metal bisque is combined with antifriction, the wear-resistant material layer based on teflon again.The junction plane of substrate and spherical bronze bisque is and melts mixed state.Metal bisque and teflon are that main antifriction, the junction plane of wear-resistant material layer are mutual embedding state.The wall thickness of bearing is between the 0.5mm to 5.0mm; The internal diameter nominal size of bearing is between Φ 6mm to the Φ 100mm; Bearing has an open seam with the nature of parallel axes.
Press the bearing products that such scheme is made, have selflubricating, light weight, matrix and be difficult for corrosion, rapid heat dissipation and adhesive strength height, long advantage of life-span.Be specially adapted to weight and require light occasion, for example: aerospace equipment, automobile, motorcycle, bicycle, fitness equipments, outdoor mobile device and household electrical appliances office machinery etc.
Description of drawings
Fig. 1 is an embodiment's of the utility model a schematic representation; Fig. 2 is the left view of Fig. 1; Fig. 3 is Fig. 1 profile.Wherein 1 is the acieral substrate; 2 is spherical bronze bisque; 3 are antifriction, wear-resistant material layer.
Embodiment
A kind of acieral three-layer composite self-lubricating bearing is sleeve-like, is combined with spherical bronze bisque 2 above the acieral substrate 1.The surface of this metal bisque is combined with antifriction, the wear-resistant material layer 3 based on teflon again.On the junction plane of substrate 1 and spherical bronze bisque 2, be and melt mixed state.Metal bisque 2 is that main antifriction, the junction plane of wear-resistant material layer 3 are mutual embedding state with teflon.The wall thickness of bearing is between the 0.5mm to 5.0mm; The internal diameter nominal size of bearing is between Φ 6mm to the Φ 100mm; Bearing has an open seam 4 with the nature of parallel axes.
Described substrate 1 is mainly acieral except that fine aluminium.
