Abstract
The invention discloses a flocculus steel ball process used for a mute ball bearing. A smooth steel ball is first prepared and then grinded by a special grinding plate with a composite brush-plating coating to prepare the flocculus steel ball with web veined surface. Based on the original casting steel ball grinding plate, the invention adopts ultra-hard ultra-fine grinding material with particle size ranging from 0.2 to 0.8 Mum; the special grinding plate with nickel, iron and ultra-hard ultra-fine grinding material composite brush-plating coating is prepared by the method of composite brush plating on the original casting grinding plate grinding troughs. The flocculus steel ball with web veined surface can be processed; furthermore, the grinding mark and direction on the surface of the steel ball is arranged trimly and the width and depth of the grinding mark are small. The fitting and vibration testing are carried out, the vibration value of the bearing is obviously improved, and the vibration and noise of the bearing are reduced.
Description
Technical field
The present invention relates to processing technology for steel ball, mainly is ' Suede ' steel ball processing technique for silent ball bearing.
Background technology
Bearing industry is one of pillar industry of Chinese national economy development, is one of China's emphasis outlet electronic product.China has now become the world the 4th Production of bearing big country, but has big gap with developed country aspect bearing life, vibration and noise.
Usually the technological method for processing of steel bearing balls is: to steel ball tarry matter or buffing, heat treatment, select group and hard grind and intensive treatment and cleaning rust-proof after, adopt steel ball lapping machine, cooperate cast iron abrasive sheet and free abrasive to carry out steel ball grinding processing.Steel ball surface is " light face " shape geometric shape, causes the shakiness of bearing oil membrane stage, thereby bear vibration, noise and life-span have been produced great influence.And adopt the cast iron nog plate to carry out last attrition process, exist skidding to make the surface thick stroke of bar occur inevitably, and in the process of lapping of exerting pressure repeatedly, also form darker damaged surface layer inevitably.Cause bearing low noise life-span, reliability to reduce.
Summary of the invention
The purpose of this invention is to provide the low ' Suede ' steel ball processing technique for silent ball bearing of a kind of vibration noise.
For achieving the above object, the present invention adopts following technical scheme: a kind of ' Suede ' steel ball processing technique for silent ball bearing, at first prepare " light face " steel ball, use special abrasive sheet to carry out attrition process " light face " steel ball of making, make " matte " steel ball that the surface presents the reticular texture pattern with composite brush coating.
The manufacture craft of described " light face " steel ball comprises hot and cold rammer or hot rolling, and cleaning is deoiled, tarry matter or buffing, and group is selected in heat treatment, hard grind, intensive treatment and cleaning rust-proof, early grind, outward appearance is observed, is selected group, lappingout to make " light face " steel ball; Described attrition process operation stock removal is at 1-2 μ m.
Described special abrasive sheet is to grind on the basis of groove at the cast iron abrasive sheet, and adopting granularity is the superhard ultra-fine abrasive material of 0.2～0.8 μ m, the special abrasive sheet of making by the method for composite brush plating with Ni-Fe-superhard ultra-fine abrasive material composite brush coating; On the plain ball grinder, utilize the special abrasive sheet of described special composite brush coating to carry out steel ball processing, under the grinding aid of grinding fluid, sphere is imposed micro cutting processing, can make " matte " steel ball that the surface presents the reticular texture pattern.
Described superhard ultra-fine abrasive material is diamond or cubic boron nitride.
The present invention is on the basis of original cast iron steel ball grinding plate, having adopted granularity is the superhard ultra-fine abrasive material of 0.2～0.8 μ m, grind on the groove at original cast iron abrasive sheet,, made and have Ni-Fe-the special abrasive sheet of superhard ultra-fine abrasive material composite brush coating by the method for composite brush plating.Can process steel ball surface and present " matte " state of reticular texture pattern, and the grinding trace of steel ball surface and direction marshalling, the width and the degree of depth of grinding trace are less.The trap vibration measuring, the bearing vibration value is significantly improved, and has reached the purpose of bearing vibration and noise reducing.
The specific embodiment
At first pass through hot and cold rammer or hot rolling, cleaning is deoiled, tarry matter or buffing, and group is selected in heat treatment, hard grind, intensive treatment and cleaning rust-proof, early grind, group is observed, selected to outward appearance, and the lappingout operation obtains " light face " steel ball.Adopting granularity is the superhard ultra-fine abrasive material (diamond) of 0.5 μ m, original processing steel ball cylinder iron abrasive sheet grind on the basis of groove, by the method for composite brush plating, make and have Ni-Fe-the special abrasive sheet of diamond composite brush coating.Adopt steel ball lapping machine (vertical or horizontal) under the grinding aid of grinding fluid, sphere to be imposed the processing of trace correct grinding then.The micro cutting processing of through for a long time, repeatedly carrying out, stock removal is made " matte " steel ball that the surface presents the reticular texture pattern at 1-2 μ m, at last " matte " steel ball cleaning rust-proof, the finished product inspection to processing.
To " matte " ball test result:, find that the steel ball surface of making presents netted superficial makings pattern under light microscope by " matte " steel ball that obtains with above-mentioned technology is observed.To the various DATA REASONINGs that the steel ball that processes carries out, the roughness value of steel ball surface has reached 0.015 μ m as can be seen, and steel ball circularity has reached 0.010 μ m, and surface waviness has reached 0.06 μ m, and ball lot diameter variation is less than 0.015 μ m.And under 500 power microscopes, observe steel ball surface and present deep mixed overlapping curve, assert to be " matte " steel ball.
Carried out trap vibration measuring test in certain accurate ball bearing company, result of the test shows under the condition that the parameters such as single ball vibration at steel ball are more or less the same, after making the steel ball trap vibration measuring that Ni-Fe-diamond lap plate processes by oneself, and the vibration values 5～7dB that descended.
Steel ball trap vibration measuring result of the test: see the following form
