Abstract
The utility model discloses a composite bearing with fillets at an oil port. The utility model aims at providing the complex bearing with fillets at the oil port which has slippery surface and good lubrication. The utility model is provided with a seam suturing round pipe on the surface; the surface of an internal hole of the round pipe is sintered with a copper powder layer; the surface of the copper powder layer is attached with a sintered anti-wear plastic layer to constitute a shaft sleeve of the composite material; an internal surface of the shaft sleeve is provided with oil holes which are distributed according to a certain rules; the utility model is characterized in that the oil port is provided with fillets. The utility model has the advantages that after the oil port is made into fillets, the surface of the matched shaft neck can be avoided scraping, furthermore, the lubricant in the oil holes is beneficial to be sucked out and the performance of the lubricant is improved.
Description
Technical field
The utility model relates to sliding bearing, relates in particular to the composite bearing of a kind of oily cave mouth band fillet.
Background technique
It is at the surface of steel plate sintering copper powder plastic layer of sintered wear-resistant again to be arranged that some composite bearings are arranged at present, and through being rolled into the sheet material of composite material, according to the specification blanking of sliding bearing, composite bearing is processed in volume circle, shaping then.In order to improve lubricating condition, generally be shaped on columniform oily cave at slidingsurface, be used to store lubricant oil or lubricating grease, and all oily cave mouths all have sharp sharp edge, lubricant oil or fat in the so both unfavorable oily cave come out, enter into slidingsurface, even also can want the match journal surface of sympodium of scratch.
The model utility content
The utility model provides a kind of smooth surface, the composite bearing of the oily cave mouth band fillet that greasy property is good.
In order to achieve the above object, the technical solution of the utility model is: it is the pipe that a joint close is arranged on the surface, surperficial sintering at the pipe endoporus has the copper powder layer, surface attachment sintering at the copper powder layer has the wear-resistant plastic layer, the axle sleeve of forming composite material, internal surface at described axle sleeve is shaped on the oily cave that distributes according to certain rules, it is characterized in that having fillet on the mouth of described oily cave.
The composite bearing of the oily cave mouth band fillet of said structure, oily cave mouth are made and can be avoided the scratch journal surface that matches behind the fillet, and help the sucking-off of lubricant oil in the oily cave, improve the lubricating oil performance.
Description of drawings
Fig. 1 is the unfolded drawing of the composite bearing of oily cave mouth band fillet; Fig. 2 is the A-A revolved sectional view of Fig. 1; Fig. 3 is the partial enlarged drawing of Fig. 2 in the K zone; Fig. 4 is the plan view of the composite bearing of band fillet; Fig. 5 is the plan view of Fig. 4.
Embodiment
The utility model will be further described below in conjunction with accompanying drawing.
Fig. 1, Fig. 2, Fig. 3 are the unfolded drawings of the composite bearing of oily cave mouth band fillet.It is as substrate 1 with low carbon steel plate or corrosion resistant plate or bronze sheet, the surface sintering has copper powder layer 2 again at the plastic layer 3 of copper powder layer 2 surface attachment sintered wear-resistant, described wear-resistant plastic 3 is meant polyoxymethylene or is the mixture that main body is added other fillers with it, make the sheet material 4 of composite material, the surface of sheet material 4 is shaped on the oily cave 5 that distributes according to certain rules, and oily cave is shaped on fillet 6 for 5 mouthfuls.According to the specification blanking of sliding bearing, wear-resistant plastic layer 3 composite bearing such as Fig. 4, shown in Figure 5 at the oily cave of inner surface belt joint close 7 mouth band fillet is processed in volume circle, shaping then.
