Description
Technical field
A kind of hobboing cutter in Shield Tunneling field is the utility model is related to, particularly a kind of configuration heavy bearing
Double-edged hobbing cutter.
Background technology
The double-edged hobbing cutter used in shield tunnel construction is because the limitation arrangement of existing tool assembly size is plain spindle at present
Hold, be that basic rated static load is relatively low the characteristics of kind of bearings, unit price is cheap, and being constructed in conventional ground consisting of hard rock, can still meet will
Ask.Though the problem of such a Bearing configuration form advantageously reduces cutter holistic cost, existed is, soft or hard uneven in high intensity
Service life is short when being tunneled in compound rock stratum, and changing different type cutter ring, improvement rotating property, adjustment hobboing cutter in trial starts torsion
It still can not alleviate central hob after the measures such as square, reduction fltting speed and the problem of bearing falls apart occur.
Double-edged hobbing cutter especially center double-edged hobbing cutter tunnels in the soft or hard uneven compound rock stratum of high intensity, due to geology rock
Layer hardness is larger, and the discontinuous of compound stratum occurs, and great impact is brought to shield hobboing cutter, and hobboing cutter is easy to occur close
Envelope failure, bearing, which falls apart, causes the phenomenon of whole knife locking, so that cutter ring easily eccentric wear even cutter integrally tears deformation and blocked
In girff.Taking-up can only be cut when progress tunnel bottom opens a position tool changing to scrap, not only cutter loss is big, also due to hobboing cutter
Easily failure causes cutterhead to damage, and influences shield-tunneling construction progress.
