Description
Technical field
The utility model relates to a kind of processing unit (plant), particularly a kind of bearing inner race raceway and profiled rollers processing unit (plant), belongs to the Grinding Technology field of bearing.
Background technology
In the roller bearing that quality requirement is higher, the surface of raceway, namely with the position of roller contact all with certain convexity, namely roller is not a line with the lateral contact face of raceway within the bearing, but a point, this is because when bearing operation, the bearing great majority damaged because of fatigue flake start at the edge of raceway, test and practice result show, at the edge one of raceway with very large contact stress concentration phenomenon.Its reason has two: one to be edge effect, and this point is extremely important, and often edge stress is than the stress several times greatly of raceway mid portion.Another reason is bearing lasso generation in the running deflection, and the contact stress of roller and lasso raceway changes, and edge stress significantly increases, larger than the stress calculated 1-2 times of its stress.Due to the superposition of these two stress, larger than the stress calculated 4-9 times of total stress.In order to eliminate the working life concentrating and improve raceway of edge stress, generally taking the approach changing raceway element line, making raceway become the raceway of band convexity.
In addition, roller runs in the raceway of band convexity, can also play minimizing rolling frictional resistance, and lubricating oil also can be relatively easy to enter rolling faying face.
The grinding of bearing inner race raceway and profiled rollers has multiple processing scheme, conventional is that emery wheel outer rim is trimmed to certain shape in the market, and then go to crush grinding workpiece outer ring with the emery wheel trimmed, workpiece inner ring outer surface is ground to the protuberance shape on emery wheel, the key of this kind of method for grinding is the finishing of emery wheel, and grinding wheel dressing method conventional in current city has, single-point oblique line dressing method, interpolation (two servo) feeding method, pattern (profiling) method etc.; Wherein single-point oblique line dressing method, emery wheel is around the center line movement of oneself, diamond pen is in emery wheel outer rim side, have a certain degree with the centre of gyration line of emery wheel and move, just the outer rim of emery wheel can be repaired dished protuberance shape, regulate the angle θ of the motion of diamond pen, just can obtain the convex value of different size, and then remove our workpiece lasso of grinding with the emery wheel trimmed, just can obtain the protuberance shape needed, the convexity of repairing out is in this way hyperbolic shape.
Along with the progressively raising of market demands, also more and more higher to the requirement of protuberance shape at present, do not require shape (as long as projection is a bit), orthodrome finally, hyperbola from initial.The logarithmic curve etc. that requires again of more producer till now.Bearing grinder manufacturer is forced to produce more and more high-end product.
More flat in the middle of the shape of logarithmic curve, be more suitable for high-precision raceway convexity and use.So under more high-precision requirement, increasing producer more trends towards the grinding of logarithmic curve, logarithmic curve has generally been repaired by two servomotor moving interpolations.Not only need the program of a set of complexity, and require also higher to the design of machinery and assembly precision, complex structure, symmetry is also not easy to control, the curve moved out often poor stability.So requiring relatively not too high occasion, orthodrome (pattern or profiling finishing), hyperbola (finishing of diamond pen single-point oblique line) also have very large market.
