The AA of Fig. 4 is to sectional view.Fig. 6 shows the structural representation of the locating plate of one embodiment of the present of invention.First, refer to
Fig. 2 and Fig. 3, main steel construction 200 include mouth 201 under main steel construction, main steel construction suitable for reading 202 and floating bearing 203.Main steel construction
Lower mouth 201 and main steel construction suitable for reading 202 are respectively provided with through hole, conventional, mouth 201 and main steel under the main steel constructions of 300 Jing of slew gear
The through hole of structure suitable for reading 202 is assembled on main steel construction 200.
A kind of row's dress method 100 of slew gear of present invention offer is specifically described below in conjunction with Fig. 1, and which includes following
Step：
Step 110, first processing technique location-plate 210, make locating plate 210 consistent with lower 220 structure of location-plate.I.e.
Locating plate 210 is identical with lower 220 size of location-plate, with an equal amount of external diameter and internal diameter.Lower location-plate 220 has the
One installing hole 221, locating plate 210 have quantity and the aperture of the second installing hole, the first installing hole 221 and the second installing hole
Also it is identical.
Lower location-plate 220, with reference to Fig. 2, is fixed on the bottom surface of mouth 201 under main steel construction by step 120, by locating plate
210 top surfaces for being fixed on mouth 201 under main steel construction.Equivalent to locating plate 210 and lower location-plate 220 from upper and lower both direction
Close up, mouth 201 under main steel construction is clipped between the two, make mouth under locating plate 210, lower location-plate 220 and main steel construction
201 through hole is mutually communicated and keeps coaxial.
Step 130, with reference to Fig. 3 and Fig. 4, slew gear 300 is assembled in place, makes slew gear 300 under main steel construction
The through hole of mouth 201 is passed through, and the gear ring 204 for adjusting the gear ring 301 and the floating bearing 203 of main steel construction 200 of slew gear 300 is nibbled
Close.
Step 140, with reference to Fig. 5, according to the first installing hole 221 of lower location-plate 220 under main steel construction on mouth 201 by under
At least two location holes 205 are processed up.The position of 205 adjusting process location-plate 210 of located hole, makes locating plate
210 the second installing hole is alignd with location hole 205, and then makes locating plate 210 complete in vertical direction with lower location-plate 220
Full weight is closed.By taking the lower location-plate 220 in Fig. 6 as an example, lower location-plate 220 is annular in shape, offers 24 in the periphery of lower location-plate 220
Individual second installing hole 221.Due to locating plate 210 it is identical with lower location-plate 220 therefore same on locating plate 210
It is provided with 24 the first installing holes.As shown in figure 5, two the second installing holes 221 are chosen on the location-plate 220, by this two
Location hole 205 processes two location holes 205 from lower to upper under main steel construction on mouth 201.Preferably, above-mentioned two second is pacified
The line in dress hole 221 so as to the position of easily adjusting process location-plate 210, makes locating through the center of circle of location-plate 220
Plate 210 is completely superposed in vertical direction with lower location-plate 220.
Step 150, the second installing hole of Jing locatings plate 210 bore periphery of mouth 201 under main steel construction open up spiral shell
Bolt installing hole.As locating plate 210 is completely superposed in vertical direction with lower location-plate 220, therefore open up bolt installation
The work in hole can be transferred to its top surface by the bottom surface of mouth 201 under main steel construction.In other words, originally by lower location-plate 220 by
Lower to be changed into by locating plate 210 from top to bottom opening up bolt mounting holes opening up bolt mounting holes toward on, this kind turns
Change can improve the working (machining) efficiency and precision for opening up bolt mounting holes.Still with the above-mentioned locating plate with 24 the first installing holes
Illustrate as a example by 210, two first installing hole is overlapped with two location holes 205, according to remaining 22 the first installing holes
Under main steel construction, the bore periphery of mouth 201 opens up 22 bolt mounting holes.Aforesaid two location holes 205 also can be used as two
Bolt mounting holes.
Step 160, removes locating plate 210 and lower location-plate 220.From bolt mounting holes position installation bolt, will return
Rotation mechanism 300 is fixed under main steel construction on mouth 201.
A kind of row's dress method 100 of slew gear that the present invention is provided utilizes locating plate 210 and lower 220 phase of location-plate
Mutually overlap, so as to change the machine direction of bolt mounting holes, improve under main steel construction mouth 201 with boring precision and processing effect
Rate, lifts whole work efficiency.
In one embodiment, before assemble slew gear 300 in place, upper location-plate 230 is fixed on
The bottom surface of main steel construction suitable for reading 202.It is preferred that adjusting the gear ring 301 of slew gear 300 and the gyroaxis of main steel construction 200
After holding 203 gear ring engagement, upper location-plate 230 is weldingly fixed on into the bottom surface of main steel construction suitable for reading 202.More preferably, upper
After location-plate 230 is weldingly fixed on the bottom surface of main steel construction suitable for reading 202, the gear ring and main steel construction of slew gear 300 are tested
The degree of engagement of the gear ring of 200 floating bearing 203.If degree of engagement not enough, needs to remove upper location-plate 230, readjust
The gear ring 301 of slew gear 300 is engaged with the gear ring of the floating bearing 203 of main steel construction 200.If degree of engagement meets the requirements,
Step 140 is entered then.
It is preferred that the step of removing locating plate 210 includes destroying locating plate 210.
It is preferred that Fig. 3 is referred to, during lifting slew gear 300, using the lifting lifting slew gear of steel wire rope 302
300, make slew gear 300 be arranged into the lower section of mouth 202 under main steel construction with upright state.More preferably, the mouth under main steel construction
202 lower section arranges moulding bed, slew gear 300 is assembled in place.
Those skilled in the art can be obvious, various modifications and variations can be carried out to the above-mentioned example embodiment of the present invention and
Without departing from the spirit and scope of the present invention.Accordingly, it is intended to make the present invention cover in appended claims and its equivalence techniques
Modifications of the present invention and modification in aspects.
