Description
Technical field
The present invention relates to a kind of shield thermomechanical components, more particularly, to a kind of center for connecting shield cutter and cutter plate driver axle
Cover component.
Background technology
In shield machine manufacturing process, rotating speed and torque output portion of the cutter head of shield machine drive shaft as cutter head of shield machine
Part, it is connected by center nested structure with cutter head of shield machine structure.Cutter head of shield machine driving by rotating speed and moment of torsion by drive shaft →
Center → cutterhead is exported.
Because cutter head of shield machine belongs to medium-and-large-sized steelwork component, its main structure need to use welding structure, it is desirable to which it is manufactured
Material has higher-strength and high-quality welding performance.The rotating speed and torque output that cutter plate driver axle drives as cutter head of shield machine
Part, it is desirable to its manufacture material has high intensity and high-quality heat treatment performance, with meet the intensity of cutter plate driver axle, toughness and
Hardness requirement.
Cutterhead and the center of driving axis connection, the requirement of high-quality welding performance and and the knife being connected with cutterhead need to be met simultaneously
The high-quality heat treatment performance requirement of disk drive shaft connection.
The content of the invention
It is an object of the present invention to overcome the above-mentioned drawbacks of the prior art and provide one kind can meet simultaneously
The welding requirements of center difference connecting portion and the center set group of the connection shield cutter and cutter plate driver axle of heat treatment requirements
Part.
The purpose of the present invention can be achieved through the following technical solutions：
A kind of center assembly for connecting shield cutter and cutter plate driver axle, by the outer cylinder body and inner barrel in interference fit
Form,
Described outer cylinder body and the disk body of shield cutter connect,
Described inner barrel is through spline and cutter plate driver axis connection.
Described outer cylinder body makes to obtain using trade mark Q345 low-alloy high-tensile structural steel, has higher structure strong
Degree and high-quality welding performance.
Described outer cylinder body and the disk body of shield cutter are welded to connect.
Described inner barrel uses trade mark 35CrMo alloy structure steel making, has higher structural strength and high-quality
Heat treatment performance.
The conditioned heat treatment of described inner barrel.
Inner barrel Tempering and Quenching uses following steps：
1) quench：It is 850 DEG C~870 DEG C to control temperature, is incubated 70 minutes, and then oil bath cools down, 20 DEG C~80 DEG C of oil temperature；
2) it is tempered：It is 550 DEG C to control temperature, is incubated 4 hours, then air cooling.
Reach Brinell hardness HB320~HB350 after the conditioned heat treatment of described inner barrel.Inner barrel material is in the hardness
Scope interior energy takes into account material static strength, impact flexibility and fatigue limit well.
Cutter head of shield machine center belongs to connection cutter head of shield machine and the key components and parts of drive shaft, to be held in the course of work
It is hit, reverses contour load, it is necessary to structural material while has high-quality welding performance and very high static strength, impact tough
Property and higher fatigue limit and material hardness.But existing homogenous material can not meet this requirement.
Compared with prior art, the present invention uses two kinds of different steel machining center nested structures, outside and cutter head of shield machine
Welding for steel structure, therefore the low-alloy high-tensile structural steel with the trade mark Q345B of cutterhead steel construction same material is used, belong to low-carbon conjunction
Jin Gang, there is high-quality welding performance, inner side and cutter plate driver axis connection, the structure, which needs to transmit, to be enough to drive what cutterhead rotated
High pulling torque, it is desirable to which material has very high static strength, impact flexibility and higher fatigue limit and material hardness, therefore uses board
Number 35CrMo structural alloy steel, welding requirements and the heat treatment requirements of center difference connecting portion can be met simultaneously, and
And it is simple in construction, solid and reliable, material cost and manufacturing cost are low, and adaptability is required for cutterhead and cutter plate driver axis connection
It is good.
