Embodiment
As shown in Figs 1-4, a kind of method for the low whirlpool axle journal for more reengining low whirling, specifically comprises the following steps：
Step 1: low whirling decomposes；
(1) before carrying out low whirling and decomposing, we by design drawing requirement, measure in advance low whirling comb ring gear 3,
The bounce of bushing 5, records the low sub- primitive technology state of whirling, and data are shown in Table 1；
Dimension measurement data before 1 low whirling of table decomposes
(2) before low whirling decomposes, make a mark in low whirlpool disk 1, comb tooth lid, old low 2 relevant position of whirlpool axle journal,
Accurate rigging position is determined for follow-up assembling；
(3) on radial drilling machine, using the method for drill bit drilling, the 36 of connection comb ring gear 3 and old low whirlpool axle journal 2 is drilled out
A 3 pins of Φ, remove and obturage comb tooth 3；36 6 pins of Φ for connecting old low whirlpool axle journal 2 and low whirlpool disk 1 are drilled out, are removed old
Low whirlpool axle journal 2；63 pins of Φ of connection spacer 4 and old low whirlpool axle journal 2 are drilled out, remove spacer 4；
Step 2: measure low 1 pin hole location of whirlpool disk；
(1) required according to design drawing, by 36 Φ, the 6 pin bore dias of low whirlpool disk 1, away from distance, the pin for combining end face
The angle of nail measures, and data are shown in Table 2；Low 6 pin hole diameters of whirlpool disk Φ are up to Φ 6.34, and faying face is arrived at pin hole center
Axial distance is 7.26~7.82 (theoretical values 7.5), and pin hole angle is 9 ° 47 ' 32 "~10 ° 21 ' 25 ".From the point of view of measurement result,
36 pin holes are circumferentially and uneven, and each hole site difference is larger, by design drawing requirement, maximum group when which repairs
Allow to be worked into Φ 7, but since pin hole maximum gauge reaches Φ 6.34, surplus is not rich, subsequently to the low whirlpool axle journal of new product
Boring work in situ in it has to be ensured that hole bit integrity with low whirlpool disk 1；
The 36 pin hole measurement results of low whirlpool disk of table 2
(2) it is that low 2 fixed pin holes of whirlpool axle journal of new product are processed on boring machine, group has made horizontal boring machine special fixture；For verification
Fixture reliability, by old low whirlpool axle journal on special fixture, carries out old 36 fixed pin holes position degrees of low whirlpool axle journal
Measurement, and low whirlpool axle journal measurement size is contrasted with free state, excluding clamping influences part；
Step 3: low 2 fixed pin holes of whirlpool axle journal of new product are processed in mapping in situ；
After the low whirlpool axle journal 2 of new product is fixed on fixture, it is placed on horizontal boring machine, according to low 1 pin hole of whirlpool disk
Position degree, processes the fixed pin holes on the low whirlpool axle journal 2 of new product；First drilled with 5.5 drill bits of Ф, then with 5.8 drill bits of Ф into
Row reaming, is finally reamed with 6 reamers of Ф, and hole edge burr is removed with scraper and group file；
Step 4: the measurement of each part fit dimension；
To ensure to coordinate, the low whirlpool axle journal of new product and the part fit dimension under dividing are measured, and calculate cooperation ruler
It is very little：
Each accessory size of 3 low whirling of table and cooperation
As can be seen from the above data, bushing 5 is cylindricalSize andSize endoporus leaves surplus,
Need to carry out supplementary processing；
Step 5: the assembling and processing of bushing；
1) bushing 5The cylindrical Vehicle Processing of size
Using the method for Vehicle Processing, for processing 5 outer round surface of bushing to size Ф 179.03, fit dimension is finally interference
0.035；
2) the whirlpool axle journal 2 low with new product of bushing 5 assembles, bushing closes up
The low whirlpool axle journal 2 of new product is heated in electric furnace, bushing 5 is pressed into the low whirlpool axle journal 2 of new product up to E1 faces are withstood, is pressed
Room temperature tightly is air-cooled to, then to closing up at bushing 5M；Closing in quality versus's original platform part is qualified；After closing in, at closing in into
Row dyeing inspection, it is qualified；
3) bushing 5The mill processing of size endoporus
After bushing 5 is assembled on the low whirlpool axle journal 2 of new product, mill processing is carried out to 5 endoporus of bushing, is ensuredSize and
Surface roughness Ra 0.1 requires；
Step 6: the assembling of spacer 4, Combined machining；
It is attached on the low whirlpool axle journal 2 of new product, is cooled to room temperature after spacer 4 is heated；Check the whirlpool axle journal 2 low with new product of spacer 4
Compactness, 0.03 clearance gauge is not by for qualification；The low whirlpool axle journal 2 of new product with spacer 4 is loaded into fixture, on radial drilling machine,
By the hole on spacer 4,6 brill, expansion, hinge 3 pin holes of Φ are combined to the whirlpool axle journal 2 low with new product of spacer 4 extremely
Fixed pin is assembled after fraising, is closed up, it is qualified to carrying out dyeing inspection at closing in；
Step 7: the low whirlpool axle journal 2 of new product and low whirlpool disk 1 assemble, Combined machining；
The low whirlpool axle journal 2 of new product and 1 corresponding hole of low whirlpool disk are carried out into mark in advance, by the low 2 fork-shaped knot of whirlpool axle journal of new product
Structure inner wall hole burr removes, and new product low 2 inner wall of whirlpool axle journal compressed air is blown down totally；, will after low whirlpool disk 1 is heated
The low whirlpool axle journal 2 of new product is positioned with 6 positioning pin of Φ as on mark position quick press mounting to low whirlpool disk 1, is ensured low whirlpool disk
1 whirlpool low with new product axle journal, 2 hole site overlaps；
After assembling, the low whirlpool axle journal 2 of new product and low whirlpool disk 1 installation side surface fitting situation are checked, 0.03 clearance gauge is obstructed
Cross as qualification；Check that low 1 wheel rim surface of whirlpool disk bounce is not more than 0.08 on three cylindrical coordinates boring machines, survey as 0.015；
By the hole on low whirlpool axle journal, 36 brill, expansion, hinge 6 pin holes of Φ are combined to low whirlpool axle journal and low whirlpool disk；Press
The design drawing pin hole maximum can ream to Φ 7, since low whirlpool disk foramen primum full-size has reached Φ 6.34, add first
The work hole is final to ream to size to determine groupIt is qualified；The method that remaining hole uses a hole one processing, most
Final processing is extremely 36 fixed pins are assembled after fraising, ensure low 2 surface of whirlpool axle journal of the non-bulging new product of fixed pin；
Step 8: comb ring gear 3 assembles, Combined machining；
It is pressed on the low whirlpool axle journal 2 of new product, is cooled to room temperature by mark position before decomposition after comb ring gear 3 is heated；Check
The 2 surface compactness of whirlpool axle journal low with new product of comb ring gear 3,0.03 clearance gauge is not by for qualification；Check that comb 3 surface run_outs of ring gear are little
In 0.1；Low whirling with comb ring gear 3 is loaded into fixture, on radial drilling machine, by the hole on comb ring gear 3, to comb ring gear
3 whirlpool low with new product axle journals 2 are combined 36 brill, expansion, hinge 3 pin holes of Φ extremelyFixed pin is assembled after fraising, is closed up,
It is qualified to carrying out dyeing inspection at closing in；
Step 9: measurement；
After part combination completion of processing, by the project measured before decomposition, low whirling is remeasured, and and is divided
Data are contrasted before solution, as a result meet design drawing requirement, are not much different with data before decomposition, data are shown in Table 4；
4 low whirling of table repair after with data comparison before decomposition
