Abstract
Solid lubricant for slide-plate of bow collector is a kind of conductivity that has, and is applicable to the solid lubricant of electric locomotive powder metallurgy current-collecting member.The present invention's paraffin, low molecular polyethylene, ethylene-vinyl acetate resin is made binding agent, by melting mixing with graphite, MOS
2, WS
2, and Zn, Sn, Pb, Bi metal-powder particulate is consolidated.The present invention and electric locomotive powder metallurgy current-collecting member are used the work-ing life that has prolonged contact line conducting wire and slide plate.
Description
The present invention relates to a kind of solid lubricant that certain conductivity is arranged, be specially adapted to the lubricated of electric locomotive powder metallurgy current-collecting member.
The powder metallurgy current-collecting member that adopts on the block of bow collector of electric locomotive is bigger to the abrasion of contact system copper conductor at present.Once adopted the way of butter or other grease lubrication in order to reduce abrasion.Can only work at short notice because lipid is lubricated, in Exposure to Sunlight, rain dashes and the dust storm effect is descended very fast ineffectively, and causes roof to pollute, and the maintenance work amount increases.
Order of the present invention ground is the shortcoming that overcomes existing lubricant, and a kind of solid lubricant that has certain conductivity and good lubricity is arranged is provided.
Technical scheme of the present invention is achieved in that solid lubricant for slide-plate of bow collector is a kind of solid lubricant with conductivity, is applicable to the lubricated of electric locomotive powder metallurgy current-collecting member.Its special character is to use paraffin, and low molecular polyethylene, ethylene-vinyl acetate resin are made binding agent, and fusion adds graphite, MOS
2, WS
2And Zn, Sn, Pb, Bi metal-powder particulate.Method with casting is made, and its concrete proportioning process is: with graphite, MOS
2, WS
2In one or more and 5-40% weight and one or more 0-15% weight among Zn, Sn, Pb, the Bi, with paraffin, low molecular polyethylene, one or more 40-90% weight in the ethylene-vinyl acetate resin melt in 120-180 ℃ constant temperature molten bath.Stir, be poured in the special model and be frozen into solid lubricant.
Solid lubricant of the present invention in use, can form uniform lubricant film at powder metallurgy slide plate and contact wire surface, thereby reduce abrasion greatly, get in slip and to flow through in the journey, under certain pressure, the metal-powder particulate forms a large amount of conductive channels, has increased effective contact area, improve conductivity, reduced the consumption of electric energy.
Now describe embodiments of the invention in conjunction with the accompanying drawings in detail:
Technical process of the present invention as shown in Figure 1
Paraffin, low molecular polyethylene and ethylene-vinyl acetate resin are put into temperature bath, stir 120-180 ℃ of heat fused.With graphite, MOS
2, WS
2Add the molten bath, mix.Add Zn, Sn, Pb, Bi metal-powder particulate, stir.Keeping casting under the 120-180 ℃ of temperature, be cooled to room temperature, obtain the solid lubricant of desired size at last by machining.
The example explanation:
With 29% weight paraffin, 20% weight low molecular polyethylene, 15% weight ethylene-vinyl acetate resin are put into 120-180 ℃ constant temperature molten bath Rongization And and are stirred, and add 30% weight graphite and 1% weight MOS again
2, mix, add 5% weight Zn powder at last, stir, under keeping 120-180 ℃ of temperature, be poured in the special model, cool to room temperature obtains required size with machine-tooled method.
Solid lubricant of the present invention and powder metallurgy slide plate are used, and make the abrasion of contact line conducting wire and slide plate self reduce more than 40%.
