Abstract
The invention belongs to the technical field of mechanical equipment for tunnel construction and relates to a cutter, and particularly to a multi-edge flange-type hob. The multi-edge flange-type hob disclosed by the invention comprises a hob shaft and a hob ring installed on the hob shaft; a first cutting edge and second cutting edges positioned at two sides of the first cutting edge are arranged on the hob ring; and the first cutting edge is higher than the second cutting edges. By adoption the technical scheme in the multi-edge flange-type hob disclosed by the invention, the first cutting edge in the middle is higher than the second cutting edges at two sides. As a big angle of inclination between the flange-type hob and a central line of a tunnel and a high linear velocity of the flange-type hob, through the impact of a big axial force while trimming and pore broadening in hard rocks, changes of the loads at two sides of the cutting edges is great, the stress situation is complex and the work condition is very serious, so that the hob with the structure can effectively reduce the degree of eccentric wear of the hob and improve the service life of the hob.
Description
Technical field
the invention belongs to the tunnel construction machinery equipment technical field, relate to a kind of tunnel machine cutterhead and use cutter, relate in particular to a kind of multiple-cutting-edge limit dish-type hobboing cutter.
Background technology
shield tunnel development machine; Be called for short shield machine; Be a kind of special engineering machinery of tunnel piercing; Carry out that tunnel construction has the automaticity height, saves manpower, speed of application is fast, face sedimentation controllably when cavitation, weatherproof, excavation, reduce the influence of above ground structure and do not influence characteristics such as water surface traffic when excavating under water, under the situation long at tunnel hole line, that buried depth is bigger, with shield machine with more economical rationality of shield machine construction.
are equipped with multiple cutter at the cutterhead of shield machine because of the difference of geological conditions and installation site; Wherein center line has higher than high inclination-angle and linear velocity limit dish-type hobboing cutter in the tunnel because of it; Receive bigger eccentric axial impact force when deburring in hard rock, reaming; Blade both sides load change is very big, and the work operating mode is very abominable.
Summary of the invention
the object of the present invention is to provide a kind of multiple-cutting-edge limit dish-type hobboing cutter in order to address the above problem.
are in order to reach above purpose; The technical scheme that the present invention adopts is: multiple-cutting-edge limit dish-type hobboing cutter; It comprises cutter shaft and is installed in the hobboing cutter cutter ring on the cutter shaft; Have first blade and second blade that is positioned at the first blade both sides on the hobboing cutter cutter ring, first blade is higher than second blade.
further.The two ends of cutter shaft are provided with the hobboing cutter end cap.
are provided with bearing between cutter shaft and the hobboing cutter cutter ring further.
further, the two ends of cutter shaft are provided with bearing (ball) cover.
further, are provided with sealing device between bearing (ball) cover and the cutter ring.
further, the hobboing cutter end cap is fixed on the outside of bearing (ball) cover.
owing to adopted technique scheme, multiple-cutting-edge of the present invention limit dish-type hobboing cutter, and the first middle blade is higher than second blade of both sides; When deburring, reaming; Under the effect of offset loading force, can effectively reduce the degree of cutter eccentric wear, improve the application life of cutter.
Description of drawings
accompanying drawing 1 is the structural representation of multiple-cutting-edge of the present invention limit dish-type hobboing cutter.
Label is among the figure:
1, cutter shaft; 2, hobboing cutter cutter ring; 21, first blade; 22, second blade; 23, snap ring; 3, hobboing cutter end cap; 4, bearing; 5, bearing (ball) cover; 6, sealing device; 7, bolt.
The specific embodiment
Set forth preferred embodiment of the present invention below in conjunction with accompanying drawing in detail
, thereby so that advantage of the present invention and characteristic can be easier to it will be appreciated by those skilled in the art that protection scope of the present invention is made more explicit defining.
can be found out from the structural representation of accompanying drawing 1; The invention provides multiple-cutting-edge limit dish-type hobboing cutter; It comprises cutter shaft 1 and is installed in the hobboing cutter cutter ring 2 on the cutter shaft 1; Have first blade 21 on the hobboing cutter cutter ring 2 and be higher than second blade 22 with second blade, 22, the first blades 21 that are positioned at first blade, 21 both sides.
The two ends of
cutter shaft 1 are provided with hobboing cutter end cap 3.
Be provided with bearing 4 between
cutter shaft 1 and the hobboing cutter cutter ring 2; Bearing 4 in the present embodiment is a taper roll bearing; Concentrate because the roller of taper roll bearing and the contact wire of raceway contact point correction can reduce stress, so taper roll bearing can bear big radial load and axial load.
The two ends of
cutter shaft 1 are provided with bearing (ball) cover 5.
Be provided with sealing device 6 between
bearing (ball) cover 5 and the cutter ring 2, preventing the degeneration in the bearing portion and to expose, and it is inner to prevent that outside dust, moisture, foreign matter etc. from getting into bearings, to guarantee the operate as normal of hobboing cutter.
hobboing cutter end cap 3 is fixed on the outside of bearing (ball) cover 5, and in the present embodiment shown in accompanying drawing 1, hobboing cutter end cap 3 fixes through bolt 7 and bearing (ball) cover 5.
the foregoing description only is explanation technical conceive of the present invention and characteristics, and its purpose is to let the personage who is familiar with this technology can understand content of the present invention and enforcement according to this, can not limit protection scope of the present invention with this.All equivalences that spirit is done according to the present invention change or modify, and all should be encompassed within protection scope of the present invention.
