Abstract
The utility model discloses a shield constructs owner and drives HBW grease chamber labyrinth structure, including inside seal clamp ring, end cover, external seal clamp ring, sealed spacer and lip seal, multi -seal spacer and lip seal set up in the cavity that is formed by inside seal clamp ring, end cover and external seal clamp ring, and HBW grease chamber is provided with labyrinth seals before first lip seal. The utility model discloses a sealed form of labyrinth seals and lip seal combination makes sealing performance further strengthen, and it is sealed and lubricated to implement first way to the cutter connection flange, keeps apart main drive and muddy water, dregs and the grit granule of blade disc side, provides good operating environment for the main drive.
Description
Technical field
This utility model relates to a kind of shield owner and drives HBW oils and fats chamber labyrinth structure, belongs to Tunnel Engineering
Technical field.
Background technology
Moment of torsion needed for shield machine is the special engineering machinery of a kind of tunnel piercing, shield machine driving is driven by main
Dynamic device provides, shield owner drive by drive case, base bearing, decelerator, sealing etc. form whole
Build parts, are one of the core components of shield machine, and main drive seal and be mainly used in being main driving in
Base bearing and miscellaneous part provide good running environment.Existing shield owner is driven through in two seals
Between cavity inject and keep the lubricant grease of certain pressure, beyond oils and fats during certain pressure scope forward
Extrusion is forced in one cavity or shield machine excavation storehouse, and ensures that the lubricant grease of previous lubrication cavity will not reflux,
Thus realize sealing function.Wherein, the oils and fats chamber formed between first lip packing and sealing hold-down ring
The HBW oils and fats that general employing viscosity is bigger seals, the lip packing size driven due to shield owner
Relatively big, rigidity is less, and stress is easily generated deformation, and the dregs of cutterhead side or sand particles are easily by sealing
Gap at hold-down ring and lip packing, Water And Earth Pressures and lip packing on stratum rotate the spiral produced
Enter main drive case under gearing, and then damage base bearing and miscellaneous part.
Summary of the invention
Technical problem to be solved in the utility model is the defect existed for prior art, it is provided that a kind of
Shield owner drives HBW oils and fats chamber labyrinth structure.
For solving this technical problem, this utility model provides a kind of shield owner and drives HBW oils and fats chamber
Labyrinth structure, including interior sealing hold-down ring, end cap, external seal hold-down ring, seals spacer and lip packing,
Multiple-sealed spacer and lip packing are arranged on and are formed by interior sealing hold-down ring, end cap and external seal hold-down ring
Cavity in, before first lip packing, HBW oils and fats chamber is provided with labyrinth seal.
This utility model also includes cutterhead adpting flange, main drive case, base bearing and rotary drum, described cutter
Dish adpting flange is connected with rotary drum, and interior sealing hold-down ring is connected with rotary drum with cutterhead adpting flange, end cap,
External seal hold-down ring is connected with main drive case, and base bearing is arranged in main drive case.
Beneficial effect: this utility model uses the seal form of labyrinth seal and lip packing combination, makes close
Sealing property further enhances, and cutterhead adpting flange is implemented first and seals and lubrication, by main driving and cutter
The muddy water of dish side, dregs and sand particles isolation, be the main running environment driving and providing good.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model；
Fig. 2 is this utility model main drive flange schematic side view.
In figure: 1 cutterhead adpting flange, seal hold-down rings, 3 end caps, 4 external seal hold-down rings, 5 close in 2
Packer, 6 lip packing, 7 main drive case, 8 base bearings, 9 rotary drums.
Detailed description of the invention
Below in conjunction with the accompanying drawings and this utility model is specifically described by embodiment.
Fig. 1 show structural representation of the present utility model.
Fig. 2 show this utility model main drive flange schematic side view.
This utility model includes that cutterhead adpting flange 1, interior sealing hold-down ring 2, end cap 3, external seal compress
Ring 4, sealing spacer 5, lip packing 6, main drive case 7, base bearing 8 and rotary drum 9.
Described cutterhead adpting flange 1 is connected with rotary drum 9, interior sealing hold-down ring 2 and cutterhead adpting flange 1
Being connected with rotary drum 9, end cap 3, external seal hold-down ring 4 are connected with main drive case 7, and base bearing 8 is installed
In main drive case 7.
Multiple-sealed spacer 5 and lip packing 6 are arranged on interior sealing hold-down ring 2, end cap 3 and external seal pressure
In the cavity that tight ring 4 is formed, common by the self-tightening of each chamber pressure of grease and lip packing
Effect realizes sealing function.
First lip packing 6, the oils and fats chamber formed between interior sealing hold-down ring 2 and end cap 3 are typically adopted
The HBW oils and fats bigger by viscosity seals, at interior sealing hold-down ring 2, end cap 3 and external seal hold-down ring
In 4 cavitys formed, before first lip packing, HBW oils and fats chamber arranges one labyrinth sealing, makes high viscosity
HBW pressure grease be not only full of the gap between hold-down ring and sealing lip, and keep overflowing continuously,
The joint face of cutterhead adpting flange 1 is implemented first sealing and lubrication, by the mud of main driving Yu cutterhead side
Water, dregs and sand particles isolation.
On the basis of above-mentioned a kind of shield owner drives HBW oils and fats chamber labyrinth structure, improve lip packing
Machining accuracy and quality of fit, ensureing to reduce on the premise of flooded traffic the gap of grease seal passage,
Thus be preferably the main running environment driving and providing good.
This utility model uses the seal form of labyrinth seal and lip packing combination, makes sealing property enter one
Step strengthens, and cutterhead adpting flange is implemented first and seals and lubrication, by the muddy water of main driving and cutterhead side,
Dregs and sand particles isolation.
This utility model the embodiment above, is merely illustrative, and is not only, all in this practicality
Change in novel scope or in the range of equivalent this utility model is all surrounded by this utility model.
