Abstract
A method for finishing the surface of a rolling contact component, such as a bearing rolling element, a bearing ring or a traction drive rolling element, comprises the steps of: carrying out a cutting operation on the surface, subsequently calendering or burnishing the surface by means of a ball comprising a material harder than the bearing component material whereby the maximum calendering or burnishing pressure exerted on the surface is less than 7 Gpa.
Description
Invention field
The present invention relates to the fine finishing on rolling contact element surface.This element constitutes the part of roller bearing, just bearer ring or ball or roller.In the element that constitutes a rolling traction driving body part also is included in, the disk of live roll and stepless change or stepless change transmission for example.
Background technique
In finishing step, utilize ball calendering (polishing) instrument to make violent turning processing or corase grind process the position plastic deformation of the left roughness maximum in back, thereby described surface is homogenized and reinforcement.Described instrument comprises a clamp holder, and in its end, ball is supported rotationally by pressure fluid usually.Usually, the diameter of calendering ball is 2～13 millimeters.
As the result of calendering or polishing operation, the position plastic deformation of roughness maximum, formation has the surface in the lubricious material zone of equal height.Therefore of this sort surface state is just separated by groove and is had the zone of equal height and not exclusively smooth, is applicable to the application of above-mentioned anticipation, for example rolling element element, live roll etc.
Japanese patent application JP-A-9137854 has introduced a kind of method that is used to make traction drive rolling element element.According to this prior art, apply 7GPa or higher surface pressure.Therefore, there is compressive residual stress in the lower face after the processing, and the fatigue resistance that causes rolling increases, and stops surface layer to peel off.The method of being discussed is declared in 0.1～0.2 millimeter compressive stress of locating to produce about 1.5GPa of lower face.
Yet find that under specific condition although improved the anti-strip resistance, descend to working life.Therefore should improve this method, so that eliminate side effect.
Summary of the invention
The method that the purpose of this invention is to provide a kind of fine finishing rolling contact element surface, this element have good frictional behaviour and have long contact fatigue life, good resistance to marring and the good ability of setting up lubricant film.
Utilize the method on rolling contact element surfaces such as a kind of fine finishing such as bearing element body member, bearer ring or traction drive rolling element element to achieve this end, this method comprises the steps:
The cutting operation is carried out on this surface;
Utilize ball subsequently, calendering or polishing are carried out in this surface, the material that described bag contains is harder than the material of rolling contact element, thereby is applied to this lip-deep maximum calendering or polish pressure less than 7GPa.
By control calendering or polish pressure, make it less than 7GPa, at first obtain to have zone or crestal surface after the pressing of desirable pattern or tissue, described zone is separate by groove.Zone after the pressing has identical height, makes each several part all bear load equably.On the other hand,, make the compressive stress on residual surface and inferior surface reduce to the restriction that calendering pressure is carried out, thus life-saving.
Be preferably in or produce compressive stress in lower face, this compressive stress is anything but greater than 1GPa.
Preferably this compressive stress is anything but greater than 0.8Gpa
Because the element surface of being discussed stands overrolling, therefore produce plastic deformation, so can expect having carried out running in the fabrication stage.Therefore bearing no longer needs running in.
By with (acutely) cutting and calendering operative combination in single track turning is processed, can adopt quick and economic mode to carry out the processing of being discussed,
The calendering ball can be roll type or sliding-type.
Can partly carry out repeatedly calendering or polishing to special surface in addition.
Gait of march by selection tool can realize repeatedly calendering or polishing, and this instrument carries ball with this mode, and promptly with respect to the turning rotational velocity of target, described lip-deep each point is more than once, is contacted by described ball but be no more than 5 times.
Hereinafter will at length introduce the present invention in conjunction with the accompanying drawings.
Brief description
Fig. 1 has shown by grinding the state on the surface that obtains;
Fig. 2 has shown the surface that utilizes method processing of the present invention to be obtained.
Preferred embodiment is introduced
Utilize cutting and grinding subsequently, obtain the surface of bearer ring or live roll just, surface shown in Figure 1.
This surface has the regular pattern of being made up of groove 2 and ridge 1, and the iso standard RA of acquisition is 0.2 micron.
By violent machining operation and calendering subsequently or polishing, obtain surface shown in Figure 2, this surface comprises the groove 3 between the zone 4.Usually roughness RA is 0.27, and wherein the roughness on described zone (not needing flat fully) is the RA0.1 micron.
It is extremely important that zone 4 has identical height, thereby obtain perfectly evenly to bear load capacity.Therefore fatigue life is almost with very smooth surperficial identical.
According to the present invention, the compressive residual stress on surface and inferior surface is less than 0.8GPa.
