Described cutter plate driver mechanism front end face and periphery pass through cutterhead face seal components by the force transmission ring moving with quiet
Power block clearance seal only, inner circumferential and rear portion end face pass through cutterhead radial seal assembly by the force transmission ring moving with static
Center storehouse clearance seal.
The invention has the beneficial effects as follows：
Slewing bearing is installed with cutter plate driver mechanism seals assembly and is positioned on force transmission ring by the present invention, revolving support
The motion outer ring bolt of bearing is fixedly connected with force transmission ring, then integral assembling is on power block.Power case lid periphery spiral shell
Bolt is fixed on power block, and bearing static inner ring bolt is fixedly connected with power case lid.Bolt and power are passed through in center storehouse
Case lid is fixedly connected.In work progress, once there is critical failure in shield excavation machine cutter plate driver mechanism slewing bearing,
The dismounting troubleshooting maintenance of part can be carried out or update, so that equipment is run well and work with effective, thus ensureing that engineering can be smoothly
Completion.
In addition, cutter plate driver mechanism front end face and periphery are to be moved, by black box, the force transmission ring moving with static
Power block carries out clearance seal, and inner circumferential and rear portion end face are to be entered the force transmission ring of motion with static center storehouse by black box
Row clearance seal.Cutter plate driver mechanism seals effectively be completely to maintain slewing bearing cleaning, lubrication, room temperature building ring
The guarantee in border, so that cutter plate driver mechanism can normally run.

Specific embodiment
The invention will be further described with embodiment below in conjunction with the accompanying drawings.
As shown in Figure 1 to 11, the fixing dress of the detachable slewing bearing of a kind of shield excavation machine cutter plate driver mechanism
Put, including cutterhead face seal components 1, transmission ring 2, cutterhead radial seal assembly 3, center storehouse 4, center storehouse screw 5, headstock
Seat bolt 6, drive pinion positioning bearing 7, power block 8, drive pinion 9, center storehouse and power case lid connecting bolt 10,
Power case lid and power block connecting bolt 11, force transmission ring and floating bearing connecting bolt 12, slewing bearing 13, headstock
Lid 14, slewing bearing and power case lid connecting bolt 15, motor and reducing gear 16, cutter plate driver mechanism seals assembly,
Cutter plate driver mechanism etc..
Slewing bearing 13 is installed with drive mechanism black box and is positioned on force transmission ring 2, slewing bearing 13
Motion outer ring bolt is fixedly connected with force transmission ring 2, then integral assembling is on power block 8；Slewing bearing 13 static
Inner ring bolt is fixedly connected with power case lid 14, and power case lid 14 is fixed by bolts on power block 8；Center storehouse 4 is passed through
