Abstract
The invention discloses a process for manufacturing a roller bearing cage, and belongs to the technical field of manufacture of bearings. The process particularly includes steps of fusing iron at a high temperature to obtain liquid iron, controlling the As content of the liquid iron to range from 0.004% to 0.005% and performing forming and cooling for the liquid iron to obtain a formed part; cleaning surfaces of the obtained formed part; washing the formed part by 5 minutes; phosphating the formed part after the surfaces of the formed part are dried by air, particularly, placing the formed part in phosphoric acid solution with the concentration ranging from 3% to 8% to phosphate the formed part, and continuously slowly stirring the formed part for 45 minutes; washing the formed part by clear water for 5 minutes; and immersing the formed part in oil for 2 minutes. The process has the advantages that the bearing cage is superior to the traditional cage in aspects of tensile strength, elongation, abrasion resistance and hardness, and a polyether-ether-ketone plastic layer is further arranged on the surface of a body of the roller bearing cage, so that the service life of the bearing cage is prolonged.
Description
Technical fieldThe present invention relates to a kind of roller bearing retainer production technology, belong to the Production of bearing technical field.
Background techniqueGenerally, the retainer of bearing is selected softer material, first-selected low carbon steel.Under the environment of high temperature or humidity, corrosion, operating conditions also has the retainer of the materials such as iron, copper in addition than using stainless steel, nylon, phenolic resin under complex situations.The effect of retainer is to make the arrangement of rolling element in bearing race to keep fixed range, prevents from running pearl, avoids stinging mutually mill between rolling element, makes simultaneously being uniformly distributed along the circumference of rolling element, reduces the adverse effect that the on-stream play in bearing play brings.The first-selected soft material of retainer is the wearing and tearing of avoiding aggravating rolling element in bearing, can extend the working life of bearing.and under complex environment, owing to hanging down the anti-oxidant of charcoal steel, anticorrosive, heat-resisting ability is relatively poor, bearing can produce huge heat and wearing and tearing in the process of running up, retainer is easy to damage under this situation, cause the infringement of bearing integral, therefore, the selection of retainer material is very important, not only to resistance to wear, and heat-conducting property will be got well, the retainer that present stage uses mostly is copper, aluminium, the material manufacturings such as steel plate, although can keep certain intensity, but perishable, easy to wear, and difficulty of processing is large, research and develop novel roller bearing retainer imperative.
Summary of the invention
Defective in view of prior art exists the purpose of this invention is to provide a kind of resistance to wearing, the roller bearing retainer production technology of long service life.
For achieving the above object, the technology used in the present invention solution is: a kind of roller bearing retainer production technology, it is characterized in that concrete steps are as follows: 1, high temperature is fused into molten iron with iron, As content is controlled at 0.004%-0.005%, be poured in mould moulding roller bearing retainer, natural cooling processing; 2, the profiled member that obtains is carried out surface clean: be to soak 6-8 minute in the sodium carbonate of 4%-5% and sodium hydroxide mixed solution at the content of 95-100 ℃, then add 3.5% tertiary sodium phosphate in the dipping fluid, continue to soak 6-8 minute; 3, put into 12% dilute sulfuric acid acidification; 4, clear water rinsed 5 minutes; 5, after the surface is air-dry, carry out phosphatization and process, place phosphatization and process in the phosphoric acid solution of 3%-8%, and slowly stir, continue 45 minutes; 6, clear water rinsed 5 minutes; 7, oil immersion is 2 minutes.
A kind of roller bearing retainer comprises body, and along the positioning hole that is used for positioning rolling body that radially is evenly arranged of body, this external surface coating poly ether ether ketone plastic layer is characterized in that each constituent mass ratio is: Cu, 62%-64%; Zn, 26%-27%; Al, 4.6%-6.5%; Mn, 2.4%-3.8%; Fe, 2.3%-3.8%; As, 0.004%-0.005%.
The thickness of described poly ether ether ketone plastic layer is 14 μ m-4 μ m.
Described body adopt As casting Cu in conjunction with material.
A kind of roller bearing retainer production technology, its beneficial effect is: utilize the retainer tensile strength, specific elongation, wear resistance, hardness of this explained hereafter all higher than traditional retainer, body surface also has the poly ether ether ketone plastic layer, extends retainer working life.
