Background technology
Finnish patent 62575 discloses a kind of cylinder group drive unit of traditional paper machine baker, and in this device, the drive unit of a plurality of cylinders is integrated as a whole.The axle of each cylinder all can be rotated by master gear, and whole cylinder group can be rotated by a driving shaft.A pinion that is arranged on this driving shaft makes selected idler gear rotation, and pulling force can be assigned on the most contiguous master gear by a plurality of idler gears by this idler gear, and continues to be assigned on the master gear of back by idler gear.The axle and the power shaft of these cylinders and idler gear are installed on the housing by bearing.This structure does not allow the cylinder dislocation, but in fact, when this structure has been made shaping, for example because the problem of cylinder dislocation still may appear in the sinking of ground.Finland's utility model patent 4507 has solved this problem from technical standpoint.According to this patent, the master gear of drum shaft rotation is installed on the housing with bearing, and engages with axle by a gear coupling.This gear coupling comprises the internal tooth that is arranged in the master gear, is arranged on external tooth and a sleeve on the described axle, and is provided with corresponding tooth between them.The tooth of this gear coupling is crown, so just allows to occur tangible inconsistent phenomenon.
But, are a kind of expensive solutions that are used for revising the problem of misalignment that the conventional ADS driving device exists according to the gear drive of this utility model patent 4507.A kind of technical scheme that can address this problem with low cost like this, just need be provided.
Summary of the invention
The object of the present invention is to provide a kind of being used for that traditional travelling gear is transformed into a kind of simple technique scheme that allows the structure of drum shaft dislocation.Feature of the present invention is as described in the appended claim.For replacement assembly according to the present invention, still can adopt the critical piece of existing travelling gear, so just make repair work from viable economically.And, easy to the maintenance of the base bearing of travelling gear and master gear according to the present invention.New drive unit need not be provided with expensive welding bearing for master gear in housing.
This driven wheel and bearing cap preferably are installed on the position at corresponding component place of conventional ADS driving gear, and different with traditional master gear, and the interior section of gear coupling is installed on the axle.After these assembly works are finished, the sleeve and the base bearing of gear coupling is in place.More preferably, the bearing cap of an integral type comprises the bearing housing that is used for drum shaft and master gear, but bearing cap also can be combined by a plurality of parts.In the present invention, important part is: all bearings of master gear all are installed in the bearing housing of bearing cap, in this case, do not need the housing frame is made variation.
Replacement assembly according to the present invention can utilize base bearing, the hood of traditional shell gear and the parts that some is less.

The specific embodiment
The conventional ADS driving device of the cylinder/roller in paper machine or the board machine is shown in Fig. 1 and 2, and for example open in the above-mentioned patent FI62575 that mentions.And, can also adopt drive unit according to this Finnish patent application 20035025 (HM U20040062).In Fig. 1 and 2, housing is represented that by letter r cylinder is then represented with Reference numeral 10.Can see from the outside: in this housing, maintain bearing cap 34 and hood 24.Fig. 1 shows the supply coupling part 34 of the drive unit according to the present invention.In other words, there are not difference in novel driving device and conventional ADS driving device from seeing in appearance.Fig. 1 shows interconnecting between each driver element, will be described in detail these connections below.These driver elements are linked together by their flange 14.Driving force can utilize single-stage or multi-stage gear drive disk assembly to be transferred to one of them idler gear, the whole assembly (not shown) of this intermediate gear drives.
With reference to Fig. 2, the axle of baker 10 according to traditional approach be provided with a master gear 21 ', this master gear is by on the flange 29 of bolt 26 ' be fixedly installed to axle 22.Each master gear 21 ' link together by a plurality of idler gears 18.The axle 19 of these idler gears is bearing on the bearing 20, and these bearings are supported on the frame R by its bearing housing.The bearing cap 24 of traditional type ' the supporting bearing 23 of axle 22 as the functional part of housing R.In this structure, if the problem of misalignment that on axle, occurs, master gear 21 ' can not remain in the limit of permission so with the indented joint of idler gear 18.In this case, can utilize replacement assembly this drive unit to be changed according to mode shown in Figure 3 according to Fig. 4.
(by providing support for cylinder bearing load being eliminated the back) disassembles bearing box cover 25 from structure shown in Figure 2, so just the nut 17 that is used to bearing is remained on the correct position can be backed out and retaining ring 17.1 is disassembled.After this, bearing 22 can be taken out in its casing.Then, with bearing cap 24 ' open, so just can be with by the old master's gear 21 on the flange 29 of bolt 26 ' be fixed to axle 22 ' disassemble.
After finishing inspection work, just can begin the replacement assembly of installation diagram 4b, to reach the state shown in Fig. 4 b.Assemble sequence is shown in Fig. 4 b.At first, utilize bolt 26 that the internal part 11 of gear coupling is fixed on the flange 29 of axle 22.Then, new bearing cap 24 and new master gear 21 are pushed vertically.Utilize 28 pairs of new bearing caps 24 of old bolt to carry out fastening.Then, the axle sleeve 12 of gear coupling is installed, vertically its pushing tow is put in place simply.So just tooth 12a, 12b and tooth 11a, 15a can be linked together.Utilize locating ring 12.1 vertically with its locking then.Then, just old bearing 23 and retaining ring 17.1 thereof, locking nut 17 can be in place.At last, second hand cases lid 25 is in place.
It should be appreciated by those skilled in the art: in design scope of the present invention, can also modify and modification the present invention in several ways.For example, except the sort of type that proposes above, gear coupling can be other type, as long as can assemble vertically.Similarly, the bearing assembly of bearing cap and master gear also can be other parts of bearings that is different from the above-mentioned type.
