Abstract
The invention discloses a method for processing a reinforcing ring of a large-sized thin wall complex structure bearing ring, which improves the strength of an outer ring by reducing the diameter size of the external inner diameter of the outer ring (01) so as to make the external inner diameter achieve the effect of the reinforcing ring; the size of the external inner diameter is reduced by 7.2 mm to phi 434.8 mm, so that the maximum wall thickness of the bearing ring reaches 12.6 +/- 0.2 mm; and the strength of an inner ring is improved by increasing the diameter size of the internal outer diameter of inner rings (02)(22) so as to make the internal outer diameter achieve the effect of the reinforcing ring, the size of the internal outer diameter is increased by 5.7 mm to phi 434 mm, and the maximum wall thickness of the whole bearing ring reaches 11.8 +/- 0.2 mm. The method adopts the processing mode of making the bearing ring form the reinforcing ring by reducing the diameter size of the external inner diameter of the outer ring and increasing the diameter size of the internal outer diameter, thereby facilitating the lathe processing of products, and simultaneously reducing the deformation brought by the lathe processing and thermal treatment processing of products due to thin wall and complex structure.
Description
Technical field
The invention belongs to the bearing ring processing technique field, what relate generally to is a kind of processing method of reinforcing ring of large-sized thin wall complex structure bearing ring.
Background technique
At present, in the bearing ring course of working since part carry out turning processing, therefore the heat-treatment quenching process can produce bigger part deformation, will increase a stiffening ring on part in part processing.Method for the bearing ring routine of ordinary construction is that stiffening ring is added in bearing face one side, cuts away after finally processing.But (mantle groove is directly than being 1.021 for large-sized thin-wall bearing, interior cover ditch is directly than the part that is 1.023), because the outer fissure both sides of overcoat 01 (as shown in Figure 1) have the slope, stiffening ring can't be placed on any side of lasso, otherwise have influence on the processing on slope, same two inner rings 02,22 (as Fig. 2, shown in 3), if stiffening ring is placed on datum end face one side, stiffening ring is after cutting, the position dimension precision of septal fossula can't guarantee at all, if stiffening ring is placed on the non-datum end face of interior cover, inner ring 22 its end face upper flanges is processed difficulty strengthen, efficient is extremely low, even can't process.
Summary of the invention
The processing method that the purpose of this invention is to provide a kind of reinforcing ring of large-sized thin wall complex structure bearing ring.Because of the lasso thin-walled, complex structure can't adopt normal increase stiffening ring to increase the difficult problem of lasso intensity in the processing of solution large thin-wall labyrinth bearing ring.By adopting lasso to carry the processing mode that stiffening ring increases lasso intensity, reach the amount of deformation that effective minimizing Vehicle Processing and heat treatment produce, be beneficial to the purpose of product processing.
The present invention realizes that the technological scheme that above-mentioned purpose is taked is: the outer internal diameter diameter dimension that reduces the outer ring increases outer ring intensity, make outer internal diameter play the effect of stiffening ring, its outer internal diameter size reduces 7.2mm to φ 434.8mm, makes the thickest of whole lasso reach 12.6 ± 0.2mm; The inside and outside footpath diameter size that increases inner ring increases inner ring intensity, and external diameter plays the effect of stiffening ring in making, and its inside/outside diameter size increases 5.7mm to φ 434mm, makes the thickest of whole lasso reach 11.8 ± 0.2mm.
The present invention makes lasso form the processing mode that carries stiffening ring by footpath diameter size inside and outside taking to reduce internal diameter diameter dimension outside the outer ring and increasing inner ring, be beneficial to product vehicle processing time, reduce the distortion that brings to Vehicle Processing and heat treatment process because of product thin-walled, complex structure.
The internal diameter diameter dimension increases outer ring intensity outside the minimizing outer ring, makes outer internal diameter play the effect of stiffening ring.The finished size of internal diameter is φ 444.2mm outside the outer ring, calculate by normal allowance 1.2mm, turner is of a size of about φ 443mm, adopts normal stiffening ring, generally should make the wall thickness of stiffening ring at 20mm, about width 15mm, as reduce outer internal diameter size by this, it is too big that back operation is returned the car allowance, contrast by experiment, finally determine outer internal diameter size is reduced 7.2mm to φ 434.8mm, the thickest of whole lasso is reached about 12.6 ± 0.2mm, played good stiffening effect and processing effect.
The inside and outside footpath diameter size that increases inner ring increases inner ring intensity, and external diameter plays the effect of stiffening ring in making.The finished size of interior external diameter is φ 428.3mm, calculate by normal allowance 1.0mm, turner is of a size of about φ 429.3mm, equally adopt normal stiffening ring with the outer ring, generally also should make the wall thickness of stiffening ring at 20mm, about width 15mm, as increasing inside/outside diameter size by this, it is too big that back operation is returned the car allowance, contrast by experiment, finally determine now to increase inside/outside diameter size 5.7mm, the thickest of whole lasso is reached about 11.8 ± 0.2mm, played good stiffening effect and processing effect to φ 434mm

Embodiment
Processing method of the present invention and embodiment are as follows:
The described lasso of the embodiment of the invention is a large thin-wall labyrinth bearing ring.As shown in Figure 1, the finished product boundary dimension of outer ring 01 is respectively: external diameter: φ 458mm, and the ditch footpath: φ 448.572mm, outer internal diameter: φ 442.2mm, highly: 48mm.Because the outer fissure both sides of this outer ring have the slope, stiffening ring can't be placed on any side of lasso, otherwise has influence on the processing on slope, at this situation,
As shown in Figure 2, taked to reduce outer internal diameter diameter dimension, make outer internal diameter diameter dimension enough little, outer internal diameter turner size: φ 434.8mm, the degree of depth in external diameter hole gets into just and to guarantee when returning the outer internal diameter of car behind the face grinding and external diameter that its hole is logical and get final product, and turner can not bored, and does not all process when the dustproof groove 1 on other Fig. 1 finished product two sides and end face groove 2 turners, just returning the dustproof groove on car two sides behind face grinding and the external diameter after the heat treatment and the dustproof groove in mill two sides during in fine grinding, the ring face groove is the line cutting process after fine grinding.Make outer internal diameter turner, heat treatment and just when face grinding, external diameter to play the effect of stiffening ring.Shown in Fig. 3,5, the finished product boundary dimension that two inner rings are 02,22 is respectively: the imperial palace external diameter: φ 428.3mm, and little interior external diameter: φ 423.5mm, the ditch footpath: φ 421.458mm, internal diameter: φ 412mm, highly: 24mm (not comprising flange 5 height).If stiffening ring is placed on datum end face one side, stiffening ring is after cutting, the position dimension precision of septal fossula can't guarantee at all, if stiffening ring is placed on the non-datum end face of interior cover, 22 its end face upper flanges 5 are processed difficulty to be strengthened, efficient is extremely low, even can't process, therefore as Fig. 4, shown in 6, with increasing the turner inside/outside diameter size, and make greatly to φ 434mm, little two inside/outside diameter size unanimities are at first face grinding, interior external diameter, it is big to return car behind the internal diameter, step 3 in little two on external diameter and the interior external diameter, carefully, whole grinder preface is regrinded greatly, end face groove 4 line cutting process after fine grinding of external diameter and step 3,02 in little.
