Part it is desirable to its manufacture material has the heat treatment performance of high intensity and high-quality, with meet the intensity of cutter plate driver axle, toughness and
Hardness requirement.
The center that cutterhead is connected with drive shaft, need to be met the high-quality welding performance being connected with cutterhead simultaneously and require and and knife
The high-quality heat treatment performance that disk drive shaft connects requires.
Utility model content
The purpose of this utility model is exactly to provide one kind can be to overcome the defect that above-mentioned prior art exists simultaneously
Meet the center that the center difference welding requirements of connecting portion and the novel shield cutterhead of heat treatment requirements are connected with drive shaft
Nested structure.
The purpose of this utility model can be achieved through the following technical solutions:
The center nested structure that a kind of novel shield cutterhead is connected with drive shaft, by the outer cylinder body in interference fit and inner barrel
Constitute,
Described outer cylinder body is connected with the disk body of shield cutter,
Described inner barrel is connected with cutter plate driver axle through spline.
Described outer cylinder body is made using the low-alloy high-tensile structural steel of trade mark q345 and obtains, and has higher structure strong
Degree and the welding performance of high-quality.
Described outer cylinder body is welded to connect with the disk body of shield cutter.
Described inner barrel adopts the alloy structure steel making of trade mark 35crmo, has higher structural strength and high-quality
Heat treatment performance.
The conditioned heat treatment of described inner barrel.
Inner barrel Tempering and Quenching adopts following steps:
1) quench: control temperature to be 850 DEG C～870 DEG C, be incubated 70 minutes, then oil bath cooling, 20 DEG C～80 DEG C of oil temperature；
2) it is tempered: control temperature to be 550 DEG C, be incubated 4 hours, then air cooling.
Brinell hardness hb320～hb350 is reached after the conditioned heat treatment of described inner barrel.Inner barrel material is in this hardness
Scope interior energy takes into account material static strength, impact flexibility and fatigue limit well.
Cutter head of shield machine center belongs to the key components and partss connecting cutter head of shield machine and drive shaft, will hold in work process
It is hit, reverses contour load, Structure of need material has the welding performance of high-quality and very high static strength, impact tough simultaneously
Property and higher fatigue limit and material hardness.But existing homogenous material cannot meet this requirement.
Compared with prior art, this utility model adopts two kinds of different steel machining center nested structures, outside and shield machine
Cutterhead welding for steel structure, therefore using the low-alloy high-tensile structural steel with the trade mark q345b of cutterhead steel construction same material, belong to low
Carbon alloy steel, has the welding performance of high-quality, and inner side is connected with cutter plate driver axle, and this structure needs transmission enough to drive cutterhead to turn
Dynamic high pulling torque is it is desirable to material has very high static strength, impact flexibility and higher fatigue limit and material hardness, therefore adopts
With the structural alloy steel of trade mark 35crmo, the welding requirements of center difference connecting portion can be met simultaneously and heat treatment will
Ask, and structure is simple, solid and reliable, material cost and low cost of manufacture, cutterhead is fitted with cutter plate driver axle connection request
Answering property is good.
