Detailed description of the invention
Below in conjunction with the accompanying drawings, the present invention is described further:
As shown in Figure 1, Figure 2, Figure 3 shows, variable element pressure balance cutter driving device of shield machine, including be connected with cutterhead
Driving box 15, is positioned at the reductor of driving box 15, motor and sealed lubrication system, and described driving box 15 is semiclosed annular
Casing, its front end face is opening shape, and its rear end is the enclosed construction leaving power drive installing hole, is hollow-core construction in the middle part of it；
The outside of described driving box 15 is provided with driving box flange, and driving box 15 is fixing even by the 3rd stud 9 with shield body
Connect；Base bearing is installed in described driving box 15, drives ring, reductor, motor, driving gear ring, driving pinion, sealing system
System and lubricating system；
Described base bearing includes base bearing inner ring 4 and base bearing outer ring 8, between base bearing inner ring 4 and base bearing outer ring 8
For bearing roller；Described base bearing outer ring 8 is connected, relative to driving box by the 4th stud 7 is fixing with driving box 15
15 transfixions；Base bearing inner ring 4 is fixing with driving ring 5 to be connected；
Described driving ring 5 is fixed be connected with cutter head support, driving gear ring 14 simultaneously；Cutterhead is installed on cutter head support,
Make base bearing that whole cutterhead is played the effect of support；Described driving gear ring 14 engages with driving pinion 12；
As shown in Figure 7, Figure 8, described driving ring 5 front end is by the first stud 3 and cutterhead flange and base bearing inner ring 4
Connecting, rear end is connected with driving gear ring 14 by the second stud；
Described sealing system includes external seal system 6 and interior sealing system 1；Described external seal system 6 is positioned at driving
Between ring 5 and driving box 15；Described interior sealing system 1 is between driving box 15 and big spacer ring 2；Described big spacer ring 2 with
Driving box 15 and driving ring 5 collectively constitute Tu Cang；Reduce the inner space of driving box 15, reduce gear oil usage amount；
As shown in Figure 5, Figure 6, described lubricating system includes being arranged on driving box 15 base bearing connected with base bearing
Lubrication channel 10；The clutch shaft bearing lubrication channel 11 connected with driving pinion 12 surrounding bearing and the second lubrication bearing passage
13。
Owing to using above-mentioned design, it is possible to achieve be individually replaced or keep in repair driving gear ring 14 and base bearing；Can install and have
The driving gear ring 14 of different reference diameters, the driving pinion 12 installed simultaneously with drive gear ring 14 to mate.As shown in Figure 4,
It is driving gear ring 14 and the driving pinion 12 of two kinds of different collocation uses.
When shield machine carries out digging advance when, driving pinion drives and drives ring gear against rotation, is further driven to drive
Ring, base bearing inner ring, cutter head support rotate, and the cutterhead on cutter head support rotates under power drive, thus excavates cutterhead front
Earth.The cutter driving device of shield machine of the present invention, it is achieved that drive gear ring to separate with the inner ring of base bearing, can individually add
Work drives gear ring with maintenance, effectively reduces processing maintenance cost；
When different geology difference bid section construction, driving means needs to export two kinds of parameters (moment of torsion, rotating speed): when cutterhead needs
When wanting the high pulling torque slow-speed of revolution, use the driving pinion as shown in Fig. 2 and Fig. 4 (a) and drive gear ring；When cutterhead needs little moment of torsion
During high rotating speed, use the driving pinion as shown in Fig. 3 and Fig. 4 (b) and drive gear ring.Above-mentioned design, is being changed without deceleration
