Abstract
The invention belongs to the technical field of bearing production and discloses a ball bearing retainer production process. The production process includes steps: 1, fusing iron into molten iron at high temperature, controlling As content within 0.004-0.005%, shaping, and cooling; 2, cleaning the surface of the obtained shaped part; 3, putting in 12% dilute sulphuric acid for acidification; 4, flushing with clean water for 5 minutes; 5, phosphating after the surface is dried by air: namely putting into phosphoric acid solution of 3-8% for phosphating, and slowly stirring for 45 minutes; 6, flushing with clean water; and 7, soaking in oil for two minutes. The ball bearing retainer production process has the advantages that a bearing retainer produced by the process is higher than conventional retainers in tensile strength, elongation rate, abrasion resistance and hardness, and the surface of a body of the bearing retainer is provided with a polyether-ether-ketone plastic layer, so that the service life of the bearing retainer is prolonged.
Description
Technical fieldThe present invention relates to a kind of ball bearing retainer production technique, belong to the Production of bearing technical field.
Background technologyShaft drive has a wide range of applications in industrial production and daily life as with chain drive, geartransmission with transmission type of drive arranged side by side.traditional bearing mostly is the metallic substance manufacturing, its wear resistance, abrasion resistance is better, but easily be corroded, thereby easily deform and damage, in addition, metal bearing in use consumes a large amount of lubricating oil, general in order to guarantee the normal use of bearing, supporting retainers that is equipped with all, retainer can prevent the collision between bearing wall and rolling body, and can guide rolling body, but 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 conductivility 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 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 ball bearing retainer production technique of long service life.
For achieving the above object, the technology used in the present invention solution is: a kind of ball bearing retainer production technique, and it is characterized in that concrete steps are as follows: 1, high temperature is fused into molten iron with iron, and As content is controlled at 0.004%-0.005%, moulding, cooling; 2, the profiled member that obtains is carried out surface cleaning: 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 soak solution, continue to soak 6-8 minute; 3, put into 12% dilute sulphuric acid acidification; 4, flushing with clean water is 5 minutes; 5, after the surface is air-dry, carry out bonderizing, place bonderizing in the phosphoric acid solution of 3%-8%, and slowly stir, continue 45 minutes; 6, flushing with clean water is 5 minutes; 7, oil immersion is 2 minutes.
A kind of ball bearing retainer comprises an annular body, and along the pilot hole that is used for the place kick 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 ball bearing retainer production technique, its beneficial effect is: utilize the retainer tensile strength, unit 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 work-ing life.
