Description
Technical field
The present invention relates to a kind of grinding of peach type raceway groove and lapping technique.
Background technology
The overall grinding of peach type raceway groove and lappingout processing are always the difficulties of processing, specific as follows：
1st, using manual equipment, by adjusting emery wheel with respect to trimmer position, emery wheel is accomplished into peach-shaped, is ground, but
Channel location can not ensure.
2nd, peach-shaped raceway groove detection is carried out using ditch shape model, the manufacture of ditch shape model is difficult, it is impossible to meets required precision, causes
Detection is inaccurate.
3rd, the processing method that raceway groove finishing uses felt buff polishing.It is coarse that felt buff polishing is only capable of raising workpiece surface
Degree, but the shape and precision of channel surface can be destroyed.Channel surface can be made to produce tension simultaneously, bearing service life is influenceed.
The content of the invention
The present invention is to solve the deficiency of the existing overall grinding of peach type raceway groove and microstoning, there is provided a kind of bearing ring is whole
Body peach type raceway groove is ground and lapping technique.
The overall peach type raceway groove grinding of bearing ring of the present invention and lapping technique, are carried out according to the following steps：
First, from high precision numerical control cylindrical grinding apparatus, by bearing ring channel grinding into peach type；
2nd, overall peach type channel shape detection：
1. milling radius R is detected：By circular curvature ball along 45 ° of centerline dip, remove circular curvature ball about 1/3
Sphere, it is therefore an objective to interfered when preventing from using with channel surface, groove curvature then detected using painting process with curvature ball
Radius R；
2. channel location eccentric amount e is detected with contourgraph；
Milling radius R or the non-compliant workpiece of channel location eccentric amount e is cylindrical with high precision numerical control again
Equipment for grinding carries out grinding；Milling radius R and the standard compliant workpiece of channel location eccentric amount e are proceeded
Slightly grind；
3rd, overall peach type raceway groove is slightly ground：
1. by peach type raceway groove using symmetrical center line as boundary, both sides semlsulcus is slightly ground respectively, i.e., by oil stone clip be tuned into
Centered on semlsulcus center line, swing, bottom of trench can leave 1~2mm or so width afterwards, it is impossible to grind；
2. after both sides are ground, from the oilstone equal with overall peach type raceway groove furrow width, oilstone is first directed at center, no
Pendulum, oilstone carries out lappingout after carrying out lapping-in, lapping-in；
4th, overall peach type raceway groove lappingout：
1. by peach type raceway groove using symmetrical center line as boundary, lappingout is carried out respectively to both sides semlsulcus, i.e., by oil stone clip be tuned into
Centered on semlsulcus center line, swing, bottom of trench can leave 1~2mm or so width afterwards, it is impossible to grind；
2. after both sides are ground, from the oilstone equal with overall peach type raceway groove furrow width, oilstone is first directed at center, no
Pendulum, oilstone carries out carrying out lappingout after lapping-in, lapping-in, and feasibility study completes the overall peach of bearing ring except the pickling layer of peach type ditch bottom of trench
Type raceway groove is ground and lapping technique.
The step of step 3 1. described in oilstone half ditch roomy 0.8~1.2mm of the width than overall peach type raceway groove, step
The model SG/SCW400# of oilstone in rapid three.
The step of step 4 1. described in oilstone half ditch roomy 0.8~1.2mm of the width than overall peach type raceway groove, step
The model SGW5# of oilstone in rapid three.
The inventive method can not be swung due to grinding oilstone during bottom of trench, really carry out lappingout, bottom of trench 1mm in the method for incision
Surface roughness can be more slightly worse at left and right, due to three, 4 contact ball bearing groove bottoms be nonclient area, can meet technique will
Ask.
Beneficial effects of the present invention：
1st, the present invention solve overall peach type raceway groove can not lappingout the problem of.
2nd, the present invention solves overall peach type raceway groove detection and forbidden, and influences the problem of product quality.
Existing method has the following disadvantages：
1. model manufacture is difficult.Conventional detection method is manufacture ditch shape model, and model precision is by ditch curvature, offset
At least compressed by full size tolerance 10% precision, manufacture ditch shape model.This just brings very big difficulty to processing, often occurs
The unqualified phenomenon done over again of model.
2. concrete values can not be detected, it is qualified to judge whether.Model is to use light gap method when detecting ditch type.Pass through
The large and small model of model is placed on raceway groove, it is qualified to be judged whether by the light passed through between raceway groove and model, is only capable of determining whether
In acceptability limit, it is impossible to determine exact value.Technical merit to tester requires high, and is easy to the mistake due to visual fatigue
Sentence.
The detection method of the present invention detects ditch curvature with circular curvature ball.The accuracy of manufacture of curvature steel ball is easily met
4 μm of deviation from circular from requirement.Ditch curvature is detected using painting process with curvature ball, efficiency and the degree of accuracy with model is high all than being permitted
It is many.Channel location eccentric amount e is detected with contourgraph, actual value can be accurately measured.Both approaches are integrated and used, greatly
Improve the accuracy of detection.
3rd, lappingout further improves the geometry and percent ripple of channel surface, removes grinding skin, in raceway groove table
Face forms compression, improves the performance and surface quality of bearing.Lappingout uses oilstone and lapping liquid, eliminates well
The Wave crest and wave trough produced is ground, the percent ripple of channel surface is greatly improved, and form compression.At this moment bearing machining is extensive
Using one of the reason for lappingout.
4th, the present invention has filled up the blank of overall peach type raceway groove lappingout.
Brief description of the drawings
Fig. 1 is the profile of bearing ring peach type raceway groove.
