Description
Technical field
The present invention relates to a kind of bearing, especially relate to a kind of processing method of bearing channel.
Background technology
Bearing refers to and the turning cylinder of machine is fixed on to precalculated position and rotates the weight and the mechanical organ that be applied to load axle on of this axle with back shaft, due to bearing at top load and at a high speed its Internal and external cycle raceway groove can rub, bending, distortion, extruding, therefore need to there is high accuracy and high strength.
Existing bearing channel processing method forms (selecting from " rolling bearing manufacturing technology ") by operations such as numerically control grinder processing, Oilstone super-finishing processing.Wherein in grinding machine manufacturing procedure, the abrasion of grinding wheel of grinding machine produces larger form error to the moulding meeting of raceway groove, and the raceway groove that produces error can cause error accumulation after Oilstone super-finishing is processed.These deviation accumulations have caused the low precision of bearing, cause the life-span of bearing short, bear that rotating speed is low, the low quality phenomenon such as little of loading.
For the processing of special-shaped raceway groove, existing bearing channel processing method is difficult to it to carry out microstoning.
Chinese patent CN102275117A discloses a kind of oilstone chucking appliance grinding for bearing channel superfinishing, this oilstone chucking appliance comprises yaw body, oilstone installing hole and fork, in yaw body, be axially arranged with shoulder hole along it, fork one end is connected with yaw body by this shoulder hole, between yaw body and fork, be provided with revolute pair, yaw body is provided with two oilstone installing holes, and these two oilstone installing holes are " eight " font and are located at yaw body axis both sides, and oilstone is fixedly installed in oilstone installing hole.The yaw body of the oilstone chucking appliance that this invention is ground for bearing channel superfinishing is provided with two positions that oilstone is installed, and can realize extra coarse and essence and surpass two work steps, simplifies machine tool structure; Improve working (machining) efficiency.Between the hole of swinging head body and the axle of swing link end part, be matched in clearance, meanwhile, the length of fork axle is a bit larger tham the length of installing hole in swinging head body, is convenient to adjust the position of swinging head body.
Chinese patent CN101209531 discloses a kind of method that adopts forming rollers high-efficiency process bearing channel cutting tool, comprising: (1) first, according to the requirement design cutter of bearing channel, designs structure and size for the electrode of trimming wheel; (2) in electrode design and make after rice, taking this electrode as negative electrode, taking emery wheel as anode, on ELID orthopedic systems, install respectively, in the gap of grinding wheel cylindrical surface and electrode by there being the grinding fluid of electrolysis ability, under power supply effect, utilize the anodic solution effect in electrolytic process, the metallic matrix on emery wheel top layer is carried out to electrolysis removal, make produce anodic solution effect and remove gradually as the emery wheel metallic bond of anode, make the outstanding wheel face of abrasive particle that not affected by electrolysis, thereby realize the online finishing to emery wheel; (3) utilize the anode that profile of orthopedic emery wheel is repaired as ELID, taking carbide alloy as negative electrode, on ELID conditioning system, grinding goes out corresponding cutter.
Summary of the invention
Technical problem to be solved by this invention is that the deficiency existing for existing bearing channel processing method, provides a kind of processing method that makes bearing channel have the bearing channel of the higher accuracy of manufacture.
The present invention includes following steps:
1) reserve the surplus of 0.02～0.04mm in the inner ring of bearing matrix and the channel surface of outer ring;
2) bearing matrix is carried out to blasting treatment, the sand grains of described blasting treatment is selected diamond dust, and compressed-air actuated pressure is 6～8MPa, and the degree of depth of sandblast is 0.02～0.04mm, makes bearing channel surface form small pit;
3) bearing matrix is cleaned;
4) after matrix cleans, bearing channel is carried out to extrusion modling processing.
In step 3), the concrete grammar of described cleaning can be: bearing matrix is put into mixer, then add hot water, carry out stirring and washing; The temperature of described hot water can be 40～80 DEG C.
In step 4), the described concrete grammar that bearing channel is carried out to extrusion modling processing can be: bearing inner race is placed on fixed axis, with nut, bearing inner race is clamped again, make bearing inner race synchronize and to rotate with fixed axis, re-use molding cutter bearing inner race raceway groove is carried out to traverse feed, exert pressure, carry out extrusion modling processing; Described traverse feed can adopt slow wire feeding processing, form through microstoning; Described superlinishing dimensional accuracy is more than IT2, and surface roughness reaches
it is raw-material molding cutter that described molding cutter can adopt wolfram steel; Described molding cutter is installed higher than spindle centerline.
After numerically control grinder processing, the two procedures that directly adopts the present invention to design, i.e. blasting treatment and the extrusion modling of accurate bed.Wherein bearing channel is carried out to blasting treatment, form a large amount of uniform small pits.Adopting extrusion modling to add man-hour, because the bearing channel after blasting treatment forms a large amount of small pits, according to Hertz theory, in the time that mould contacts with raceway groove, its composite curve radius is about the radius of curvature of small rut, square being directly proportional of the extruding force of contact-making surface and composite curve radius again, therefore, extruding force when blasting treatment has reduced moulding greatly, is convenient to raceway groove through the extrusion modling of special molding cutter.The molding cutter that the present invention uses can adopt wolfram steel for raw material, carries out slow wire feeding processing, forms through superfinishing according to bearing channel shape, and more than dimensional accuracy reaches IT2, surface roughness reaches
channel dimensions precision after its extrusion modling reaches P2 level, and surface roughness reaches
meet the required precision of bearing, thereby improved the service life of bearing, reduce noise, realize high rotating speed, the high load capacity of bearing.
