Description
Technical field
The present invention relates to bearing mnanufacture technical field, especially a kind of bearing outer ring grinding process.
Background technology
Bearing top circle centerless grinding is one of conventional bearing outer ring processing method, for application medium and small model bearing also the most extensively, processing effect is also better.Due in bearing top circle centreless grinding process, the center of circle of bearing cannot be determined, therefore grinding of bearing outer ring channel cuts the rear centerless grinding needing to carry out again external diameter, like this deviation is appearred in the center of circle causing the bearing channel center of circle with bearing outside diameter.And in the bearing outer ring groove processing technique of routine, on bearing top circle, also inevitably leave the processing marking, affect outward appearance.As the outer ring processing method of patent publication No. a kind of light and narrow series precision corner contact ball bearing disclosed in CN102996649A, manufacturing procedure is corase grind end face-corase grind external diameter-mill outer internal diameter-corase grind outer fissure-corase grind fore shaft-add tempering-whole face grinding-lappingout end face-fine grinding external diameter-grind eventually fore shaft-grind eventually external diameter-grind raceway groove-superfinishing raceway groove eventually.
Summary of the invention
The object of the invention is to solve in the processing of existing outer ring, deviation is there is in the bearing channel center of circle with the bearing outside diameter center of circle, bearing channel adds man-hour, inevitably on bearing top circle, leave the processing marking, affect outward appearance, and cylindrical needs the problem of repeatedly grinding, provides a kind of technological design reasonable, utilize guide plate, ceramic support leads, without the need to carrying out the bearing outer ring grinding process of grinding after bearing outer ring is shaping again.
Above-mentioned technical problem of the present invention is mainly solved by following technical proposals: a kind of bearing outer ring grinding process, is characterized in that having following steps:
(1) blank is prepared; (2) heat treatment; (3) Double End is ground; (4) bearing top circle grinding; Cylindrical divides 3 grindings: first remove external diameter casting skin, stock removal 0.08 ~ 0.12mm; Then external diameter is roughly ground, stock removal 0.10 ~ 0.15mm; Last fine grinding bearing outside diameter, stock removal 0.035 ~ 0.04mm; (5) grinding of bearing outer ring channel is cut, and adopts ceramic support, ceramic support width=bearing outer ring nominal height-2* bearing outer ring maximum axial chamfering length-(0.2 ~ 0.4) mm; (6) bearing outer ring channel superfine milling.
The main distinction of the technical program and conventional machining mode is in bearing top circle grinding and grinding of bearing outer ring channel are cut, when bearing outside diameter grinding, by continuous print 3 grindings, directly be ground to the final size of bearing outside diameter, because being benchmark with external diameter during outer ring raceway grinding, as long as avoid raceway groove grinding not bring bad result to outer peripheral surface, it is exactly priority scheme, the design of ceramic supporting element reaches this requirement, like this, external diameter afterwards carries out grinding again with regard to not needing, and the concentricity of raceway groove and external diameter is more perfect.The guiding width of ceramic supporting element and the outer ring engineering height of processed bearing have close position relationship.
As preferably, described workpiece, the guide wheel line of centres and guide wheel, emery wheel line of centres angle are 4 ~ 8 degree, and workpiece, the emery wheel line of centres and guide wheel, emery wheel line of centres angle are 6 ~ 10 degree.Best angle design between workpiece, guide wheel, emery wheel three, makes workpiece in process, be in best stressed and stable state.The technical program is especially applicable to external diameter 100 ~ 150mm bearing machining, and now, if work piece centre-height is 13.5 ~ 19.7mm, emery wheel is 12 ~ 16.7mm relative to the displacement of workpiece.
As preferably, described ceramic support adopts zirconia ceramics to support; Ceramic support surface roughness is Ra0.19 ~ 0.23 μm.In structural ceramics, zirconia ceramics has high tenacity, high-flexural strength and high-wearing feature, and the heat-proof quality of excellence, and thermal coefficient of expansion is close to advantages such as steel; In function ceramics, zirconia ceramics has excellent resistance to elevated temperatures.Best surface roughness design avoids ceramic support to produce vestige to bearing top circle.
As preferably, described grinding of bearing outer ring channel is cut, and adopt 120 order vitrified bonding emery wheels, corase grind speed is 8 ~ 12 μm/s, determines journey 0.30 ~ 0.35mm, and fine grinding speed is 3 ~ 5 μm/s, determines journey 0.03 ~ 0.05mm.Adopt the technical program, bearing outer ring channel is also a continuous print process, and its location base is constant, to ensure the concentricity with bearing outside diameter.
As preferably, described bearing top circle grinding is provided with guide plate in the below of bearing outer ring.Guide plate and guide wheel form lower support and the location of bearing outer ring jointly.
As preferably, described guide plate has the inclined-plane tangent with bearing outer ring, and the height point on this inclined-plane is towards bearing outer ring screw-in direction, and the low spot on this inclined-plane screws out direction towards bearing outer ring.The horizontal plane that the inclined-plane of guide plate and emery wheel, guide wheel center line are formed at angle, and supports maximum weighted position during bearing outer ring grinding just.
Effective effect of the present invention is:
1. time due to bearing outside diameter grinding, being directly ground to final size, is benchmark with external diameter during outer ring raceway grinding, then after, external diameter no longer carries out grinding, raceway groove and external diameter good concentricity.
2., by the technical program, decrease external diameter mill manufacturing procedure at least one times, reduce operation turnover, improve outer ring production efficiency, reduce grinding time and processing cost.
3. outer ring raceway and external diameter not only good concentricity, Wall-Thickness Difference controllability is strong, and outer ring raceway circularity precision improves greatly.
4. the raising of Product Precision, extends the service life of bearing.
