Description
Technical field
The present invention relates to shield machine technical field, particularly relates to a kind of integral type cutter ring hobboing cutter.
Background technology
Underground space development is the engineering development direction of following great prospect, with widening for underground space development market,
Rock tunnel(ling) machine is also gradually applied to more complicated geological environment, and therefore, the cutter of rock tunnel(ling) machine is also just receiving arduousness
Challenge.Hobboing cutter is to make a kind of cutter of rock crushing by carrying out rolling extrusion on rock mass surface, and hobboing cutter cutter ring and rock mass are direct
Contact, the thrust for bearing rock tunnel(ling) machine excavate rock mass.Except the normal pressure of cutter ring to be born circumferential direction when hobboing cutter works
Outside, also it is subject to acting on for alternate stress on the tangential frictional force of cutter ring and lateral, stress is complicated, and working environment is disliked
It is bad, sewage and dregs are filled with, therefore it is higher to the reliability requirement of hobboing cutter；In major diameter rock tunnel(ling) machine, the disk of cutterhead
The characteristic that shape structures shape cutterhead is changed from small to big by the rotation linear velocity of internal diameter to outer diameter zone, therefore in outer diameter zone, rolling
The impact that knife is born also greater than inner diameter zone hobboing cutter, in this case, it is desirable to which the hobboing cutter cutter ring of outer diameter zone can be born
The shock loading of higher is without damaging.In addition, existing hob-cutter structure is unreasonable, parts are more, installation is inconvenient, and because of structure
Complicated, parts cause high failure rate more, and since hob-cutter structure is unreasonable, parts are more also so that installation space is corresponding
It is larger, cause the arrangement quantity of hobboing cutter in limited space to be restricted.
The content of the invention
For the deficiency in above-mentioned background technology, the present invention proposes a kind of integral type cutter ring hobboing cutter, solves the prior art
The technical problem that middle hobboing cutter impact strength is low, complicated and high failure rate and installation space are big.
