The present invention obtains the know-why of beneficial effect, can be according to the spy of macroscopically oilstone Yu ring raceways contact area
Levy, grind principle according to superfinishing and illustrate.Restricted by superfinishing working method, initial with the oilstone that channel shape fits like a glove
Work surface, can move interference with channel surface in oilstone swing process, and this combines with oilstone wearing character so that oil
Stone is sufficiently complex with the actual contact situation of raceway groove.For tradition super precision method and oilstone used thereof, this interference is at oilstone
Four angular zones are the most serious.Although oilstone shape of working surface and channel shape in theory and are misfitted, but oilstone and raceway groove is true
In the range of real contact is positioned at their macroscopical contact area, is restricted by macroscopic view contact area, thus oilstone is connect with raceway groove macroscopic view
The analysis in tactile district superfinishing can be ground efficiency and quality problems illustrate.
Macroscopically the contact area of oilstone and raceway groove is as shown in Figure 3.Fig. 3 is oilstone when swinging to just to ring raceways, with
The view in plane that oilstone short transverse is vertical.Typical eight prism oilstone and ring raceways in Special-shaped oilstone of the present invention
Contact area be the ABCDEFGH region shown in Fig. 3, it is shaped as octagon;Tradition super precision method oilstone contacts with lasso
Region is the JKLI region shown in Fig. 3, and it is shaped as tetragon;The contact area of superfinishing method tilting for oilstone, oilstone and lasso
Territory is the MNOP region shown in Fig. 3, and its shape is also tetragon but attitude is different from tradition super precision method.
In conjunction with Fig. 3, the know-why of the present invention and the effect of acquirement are described as follows in terms of four:
(1) compared with traditional method, the present invention is at four angular zones of traditional method contact area, i.e. ABI, CDJ, EFK, GHL in Fig. 3
Represented region, does not has oilstone material, thus greatly reduces the movement interference degree between oilstone and lasso, make oilstone work
The degree of agreement of face shape and ring raceways surface configuration improves, and oilstone surface has more and is distributed widely abrasive particle ginseng
With superfinishing, thus improve microstoning efficiency;
(2) in the contact area of oilstone of the present invention and lasso, just region represented by BCFG in the rectangular area to bottom of trench, i.e. Fig. 3
Oilstone material trench bottom region can be carried out superfinishing more fully.Trench bottom region is the groundwork district of ring raceways
Territory, during bearing runs, raceway groove occurs mainly in this region with contacting of steel ball, and the superfinishing quality in this region is to bearing performance
Impact maximum.Compared with traditional method, the method for the present invention, owing to alleviating the interference of traditional method oilstone four angular zone, makes ditch
The microstoning quality of road bottom section is improved;Compared with superfinishing method tilting with oilstone, owing in Fig. 3, BCGF region area is big
In NadPcb region area, the oilstone material that this method carries out superfinishing to trench bottom region is more, and distribution is bigger, has number
Measure more and be distributed widely abrasive particle participation superfinishing (beneficially improving superfinishing efficiency and quality), and can be wider
The ripple high point on Automatic-searching trench bottom surface is ground (beneficially improving percent ripple), so that the superfinishing of trench bottom
Crudy is more preferable.
(3) in the contact area of oilstone of the present invention and lasso, ABGH and CDEF in the region of raceway groove both sides, i.e. Fig. 3
Two represented trapezoid areas, its oilstone material can carry out superfinishing to the surface of raceway groove two side areas.Compared with traditional method,
This method is owing to alleviating the interference of four angular zones, although the oilstone material participating in raceway groove two side areas superfinishing has reduced, still
The microstoning quality of raceway groove two side areas can be ensured.Compared with superfinishing method tilting with oilstone, owing in Fig. 3, ABGH region area shows
Writing more than Mad region area, the oilstone material that this method carries out superfinishing to raceway groove two side areas is more, makes raceway groove two side areas
Superfinishing is in hgher efficiency, microstoning better quality, and region, oilstone tilting superfinishing method raceway groove both sides of the edge can be overcome (i.e. to scheme
3 section line regions) the insufficient limitation of superfinishing.Oilstone tilting superfinishing method participates in the oil of region, raceway groove both sides of the edge superfinishing
Stone material, is the material in Meh and Ofg region in Fig. 3, and the two region area is the least, participates in the oilstone abrasive particle quantity of superfinishing
Less and distribution is little, inadequate to the material removal ability in region, raceway groove both sides of the edge, easily cause this region superfinishing insufficient.
(4) the inventive method saves oilstone material than traditional method, because ABCDEFGH region area is less than IJKL in Fig. 3
Region area.
Based on angular contact ball bearing and the similarity with deep groove ball bearing raceway groove character of thrust ball bearing ring raceways,
Method slightly modified to the present invention, the superfinishing being i.e. applicable to angular contact ball bearing and thrust ball bearing ring raceways adds
Work.Such amendment still falls within the protection domain of this patent.
Choose the main thickness of oilstone to need to consider that the pros and cons of superfinishing effect is affected and balanced by it.The main thickness of oilstone
When degree is chosen bigger, favourable aspect is: the abrasive particle quantity that oilstone surface puts into grinding simultaneously is many, and oilstone automatically selects raceway groove table
Face microcosmic ripple high point carries out the wide ranges of differential grinding, is conducive to improving grinding efficiency and improving percent ripple;Disadvantageously
It is: when oilstone swings, oilstone work surface increases with the interference degrees in channel shape face, diverse location oilstone working ability in contact area
Difference also increase, cause raceway groove crudy uniformity decline even working (machining) efficiency reduce.Compared with traditional method, this method
The movement interference the most serious owing to there is not traditional method contact area four angular zone, choosing the main thickness of oilstone under similarity condition can
With larger than the oilstone thickness of traditional method, thus improve superfinishing efficiency to a greater degree and improve percent ripple.Choose oilstone
Main thickness also needs to consider the size of raceway diameter.
The Main Basis choosing the main width of oilstone is channel width and oilstone pendulum angle, and the main width of oilstone to be weighed is relatively
The pros and cons impact produced time big.After given oilstone pendulum angle, the maximum of the main width of oilstone should ensure that oilstone is put
When moving extreme position, its vertical side can be completely into raceway groove outside raceway groove, and the minima of the main width of oilstone should ensure that oil
When stone swings to inverse limit position, its vertical side can measure in raceway groove and reach trench edges, and the main width of actual oilstone should be
Choose between this minima and maximum.When oilstone main width value is bigger, the Beneficial Effect of superfinishing effect is by it: raceway groove
The superfinishing in region, both sides of the edge (hatched region as shown in Figure 3) is the most abundant, should because there being more oilstone abrasive particle to put into
The grinding in region;Adverse effect is: it is less that the oilstone material of oilstone vertical lateral edge near zone puts into the chance ground, from
Body is not easy abrasion so that on oilstone surface, the central region of easily abrasion cannot better contact with raceway groove, thus affects ditch
The superfinishing effect of road central region.The oilstone material of oilstone vertical lateral edge near zone puts into grinder can less reason
It is that these materials have more chance to be swung to outside raceway groove, such as, when oilstone swings to just to raceway groove, as shown in Figure 3
It is in the oilstone material outside two shadow regions and is at outside raceway groove not putting into grinding.
Compared with traditional method, the method for the present invention due to oilstone vertical lateral edge near zone oilstone material relatively
Few, self it is not easy to wear away produced adverse effect less, chooses the main width of oilstone under similarity condition and can compare traditional method
Oilstone width larger, thus to a greater degree improve superfinishing effect.
