Abstract
The utility model discloses a novel self-lubricating bearing for a butterfly valve. The novel self-lubricating bearing adopts a high-quality carbon constructional steel plate as a substrate; a spherical bronze powder layer is sintered on the substrate; a lead-free plastic working layer made from lead-free and polytetrafluoroethylene-based fillers is rolled and sintered on the spherical bronze powder layer; the bearing body made from three layers of lead-free composite materials is formed; a bonding surface of the substrate and the spherical bronze powder layer is in a fusion state; the thickness of the bearing body made from three layers of lead-free composite materials is 1-2.5mm, wherein the thickness of the spherical bronze powder layer is 0.20-0.35mm; and the bearing body is manufactured into a cylindrical shape with an opening seam by using a rolling process. The novel self-lubricating bearing has the characteristics of excellent wearing resistance, large bearing capacity, long service life and convenience for maintenance.
Description
Technical field
The utility model relates to a kind of sliding bearing, particularly various fluids are carried the novel butterfly valve self oiling bearing on butterfly valve.
Background technique
Traditional various butterfly valves generally adopt copper/copper alloy bearing, it adopts lubricating grease to be lubricated usually, could satisfy butterfly valve rotates in the 0-90o scope and enables, for the unlatching moment that makes valve little, be unlikely to produce the retardance phenomenon in opening-closing process, must often add grease lubrication, so troublesome maintenance, cost are high.The professional factory of some well-known butterfly valve products of recent year successfully uses international advanced technology, be arranged in the butterfly valve bearing support from a kind of self oiling bearing of external import, be used for replacing traditional copper/copper alloy bearing, also there is no in the market similar domestic self oiling bearing.
Summary of the invention
The purpose of this utility model be the to integrate with needs of international advanced technology and upgrading can work under unlubricated state and provide a kind of, have a friction factor low, and wear-resisting property is good, the self oiling bearing of the novel butterfly valve of long service life.It can be arranged on the butterfly valve product, can be widely used in the fields such as oil, chemical industry, food, medicine, light textile, urban water supply and sewerage.
The purpose of this utility model is completed by following scheme: it is take carbon constructional steel plate as matrix, described substrates sintering has the spherical bronze bisque of one deck, also apply on this spherical bronze bisque and roll and unleaded plastic working layer that sintering one deck forms with teflon and lead-free stuffing, and consist of the bearing support that a kind of unleaded 3-layer composite material is made.
The junction plane of described matrix and spherical bronze bisque is molten state, and the thickness of the bearing support that described unleaded 3-layer composite material is made is 1-2.5mm, and the thickness of wherein said spherical bronze bisque is 0.20-0.35mm.
Described bearing support employing rolling technology is made the drum with open seam.
The utility model is tested under unlubricated condition, and load reaches 8N/mm
2, friction factor during linear velocity 0.2m/s≤0.2, wear extent≤0.03mm has wear resistance good, bearing capacity, long service life power is convenient to the characteristics such as maintenance.

Label in figure: 1. spherical bronze bisque 3. plastic working layer of matrix 2..
Embodiment
Below in conjunction with accompanying drawing, the utility model is described in detail: shown in Fig. 1,2,3, the self oiling bearing of novel butterfly valve described in the utility model, it is take quality carbon structural steel as matrix 1, above described matrix 1, sintering has the spherical bronze bisque 2 of one deck, also apply on this spherical bronze bisque 2 and roll and unleaded plastic working layer 3 that sintering one deck forms with teflon and lead-free stuffing, and consist of the bearing support that a kind of unleaded 3-layer composite material is made.
The junction plane of described matrix 1 and spherical bronze bisque 2 is molten state, and the thickness of the bearing support that described unleaded 3-layer composite material is made is 1-2.5mm, and the thickness of wherein said spherical bronze bisque 2 is 0.20-0.35mm.
Described bearing support employing rolling technology is made the drum with open seam.
The utility model has not only solved the oiling agent of often will regularly annotating, troublesome maintenance, the hard nut to crack that cost is high, and have the characteristics such as the moment of unlatching reduces, long service life.Research and develop this novel butterfly valve self oiling bearing and not only make the domestic butterfly valve international advanced technology that integrates with, and save a large amount of non-ferrous metals, thoroughly eliminated simultaneously the toxic substance of requisite lead element in the Cu alloy material, from import substitutes, the needs of production domesticization have not only been solved, and the cost ratio imported product is low, and the supply of material in time is subjected to user's welcome deeply.
