It also includes 0.8 part organic oil and under 0.8 part zinc stearate. The carbon content in the finished bearing is 0.4 percent. Its manufacturing technique is as follows: mixing uniformly powder material; pressing; sintering; the sintering temperature is from 1050 centigrade degree to 1200 centigrade degree; repeating pressing or fine finishing; doing steam treatment or quenching; and doing hot immersion oil. Its advantages are no distortion and little abrasion. And it can be directly used to weld.
Description
Technical field
The present invention relates to a kind of bearing of new material, particularly a kind of weldable sintered metal powder bearing and production technology.
Background technique
The sintered metal powder bearing of Chu Xianing all passes through batch mixing-stirring-moulding-sintering-integer-double sintering-machining-heat treatment-operations such as vibration grinding-vacuum oil immersion in the market, and it is a kind of oil-impregnated bearing, realizes having oil lubrication.The critical defect of this oil-impregnated bearing in welding process is exactly that oil is easy to burning, increased the difficulty of welding.In addition, because in welding process, the high-temp combustion of electric arc reduces the oil content of bearing, has not realized oil lubrication, a kind of oil-free lubrication state occurs, does not reach the true lubrication effect, has increased frictional force, has shortened working life.Moreover; because country more and more payes attention to environmental protection; in mechanical industry; a lot of mechanical bodies change sheet metal part into by cast member; develop towards light, attractive in appearance, fairshaped direction; particularly to some low speed, rotation, the less demanding parts of slip load; it is to be directly installed on to realize on the sheet metal part and can weld that Bearing Installation requires; incorporate the lubricated characteristics of Nonlubricated bearing simultaneously; realize oil-free lubrication; but present sintered metal powder bearing can't satisfy this requirement, causes the prior art products bad adaptability.
Summary of the invention
The objective of the invention is to provide a kind of a kind of weldable sintered metal powder bearing and production technology that realizes weldability and oil-free lubrication or few oil lubrication for the deficiency that solves above-mentioned technology.
In order to achieve the above object, a kind of weldable sintered metal powder bearing that the present invention is designed, its dusty material is formed and is comprised 100 parts of iron powders, and it also comprises 0.5 to 1.2 part of plumbago, 0.4 to 0.5 part of molybdenum disulfide, 0.5 to 3 part of copper powder.In forming, dusty material also includes 0.08 part in machine oil.In order to improve self-lubricating property and to guarantee that bearing is indeformable under High Temperature High Pressure, in forming, dusty material also includes the zine stearate below 0.8 part.For the wear resistance that guarantees bearing and improve its weldability, the carbon content in the bearing completed products is percent nought point four.
The production technology of this weldable sintered metal powder bearing is that the dusty material that will determine prescription evenly mixes, suppression process adopts the one or many filling molding, pressing pressure is at 6 tons/square centimeter to 8 tons/square centimeter, sintering then, 1050 ℃ to 1200 ℃ of sintering temperatures, cool stage by stage, the temperature difference is no more than 200 ℃, multiple again the pressure or fine finishing, multiple pressure pressure can carry out steam treatment or quenching again at 1.2 tons/square centimeter to 2 tons/square centimeter, and the steam treatment temperature can be at 560 ℃ to 700 ℃, last hot dipping oil, temperature is at 20 ℃ to 160 ℃.
The resulting a kind of weldable sintered metal powder bearing of the present invention, by in mixture, adding trace elements such as the used graphite of Nonlubricated bearing, zine stearate, molybdenum disulfide, guarantee that bearing is indeformable under high temperature, high pressure, less wear realizes not having oil or few oil lubrication.Make the carbon content in the powder metallurgy composition, be increased to percent 0.4 by original 0.25 percent, thereby in welding process, be fully burned, can realize oil-free self lubrication or few oil lubrication in the working procedure; Can directly weld, change the present situation of sintered metal powder bearing weldability difference; And this weldable sintered metal powder bearing, intensity height, wear resistance are good, hardness can reach 176 and cause the 332HB stiffness units, the conventional products surface hardness can only cause the 96HB stiffness units 75, need not to add under the condition of lubricant oil, friction factor is less than 0.12, and the compression set amount is less than 0.03 millimeter, and it has very real positive effect to the development of sintered metal powder bearing.
