Abstract
A kind of push-bench is with 13 " twolip middle tooth cutter, this device mainly by: cutter shaft, Zuo Daogai, You Daogai, floating seal, cutter hub assembly, taper roll bearing, wearing layer, wedge shape carbide alloy form.Cutter hub assembly is double blade, and cutting edge place is provided with wedge shape carbide alloy; The carrying of this hobboing cutter is mainly installed to the positive cutter position on cutterhead by cutter shaft, support cutter hub assembly, and then ensure that hobboing cutter has larger bearing capacity by a pair taper roll bearing; The sealing of this hobboing cutter is made up of two pairs of floating seals, can prevent the intrusions such as outside foul, dust, muddy water and abrasive material, can prevent inner fluid or lubricating grease from revealing simultaneously; Cutter hub inlayed wedge shape carbide alloy and build-up wear-resistant layer, effectively can improve the service life of hobboing cutter body, reduce construction cost, improve efficiency of construction.
Description
Technical field
The utility model relates to push pipe machinery, specifically a kind of push-bench is with 13 " twolip middle tooth cutter.
Technical background
Show according to on-the-spot push-bench hobboing cutter Using statistics, what cause rolling blade losing efficacy because of bearing damage accounts for 80% of inefficacy Hob for cutting rock, and what cause bearing heavy wear because of seal failure accounts for 30% of failing bearings.Wherein knife body surface surface wear is also one of reason causing rolling blade losing efficacy.So push-bench in the course of the work, on its cutterhead, the carrying of hobboing cutter and the anti-wear performance of impact resistance, sealing property and cutter hub play decisive role the service life to hobboing cutter.
Summary of the invention
Technical problem to be solved in the utility model is to provide a kind ofly has relatively high bearing capacity, the push-bench hobboing cutter of stronger sealing property and good anti-wear performance, thus improve hobboing cutter service life, reduce construction cost, improve efficiency of construction.For achieving the above object, the utility model adopts following technical scheme: a kind of push-bench is with 13 " twolip middle tooth cutter, mainly by: cutter shaft (1), Zuo Daogai (2), floating seal (3), cutter hub assembly (4), taper roll bearing (5), wearing layer (6), You Daogai (7), wedge shape carbide alloy (8) form.Described cutter hub assembly (4) is double blade, and cutting edge place is provided with wedge shape carbide alloy (8); A pair taper roll bearing (5) is coaxially set up in parallel in cutter hub assembly (4); A pair taper roll bearing (5) is contained on cutter shaft (1) with left cutter lid (2), You Daogai (7) concentric; Left cutter lid (2), a pair floating seal (3) is respectively set between You Daogai (7) and cutter hub assembly (4); Fixedly realizing by arranging arc step between left cutter lid (2) and cutter shaft (1); Fastening between right cutter lid (7) and cutter shaft (2) is realized by screw threads for fastening.
Further: adopt a pair taper roll bearing, improve the adjustment performance of hobboing cutter starting torque and the bearing capacity of hobboing cutter; The two pairs of floating seals adopting pairing to use improve the sealing property of hob device.
Further: in this hob device, a pair taper roll bearing adopts back-to-back mounting means.
Further: the interior exit orifice of taper roll bearing all adopts interference fit with the fit system of each phase accessory, complete pretension amount between bearing by regulating the pretightning force of right cutter lid.
Further: often pair of floating seal is arranged in independent chamber face-to-face, wherein only there is one in rotation, such that two matched seals surfaces are relative in the plane orthogonal with cutter shaft to rotate.
Further: the uniform wedge shape carbide alloy of cutting edge, and around cutter hub assembly surface wedge shape carbide alloy build-up wear-resistant layer, such a construction increases impact resistance and the anti-wear performance of hobboing cutter cutter hub.
Owing to adopting technique scheme, the utility model has following superiority:
Taper roll bearing be adopt standard round taper roller bearing, its versatility is good, and foozle is little, and precision is high, and according to Practical Project geological condition adjustment pretension amount, can ensure that each roller can both carry stressed in assembling process; The floating seal of paired use realizes sealing function by the contacting with each other of matched seal surface of precise finiss, and sealing property is stronger, and has better centring property.Meanwhile, cutting edge inlays wedge shape carbide alloy, knife body surface surface build-up welding wearing layer, improves impact resistance and the anti-wear performance of hobboing cutter.While the service life extending hobboing cutter greatly, reduce construction cost, improve efficiency of construction.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model.
In figure: cutter shaft (1), Zuo Daogai (2), floating seal (3), cutter hub assembly (4), taper roll bearing (5), wearing layer (6), You Daogai (7), wedge shape carbide alloy (8).
Detailed description of the invention
Below in conjunction with accompanying drawing, the utility model is described in further details:
Cutter hub assembly makes finished product by blank forging, roughing, heat treatment, semifinishing, boring, tungsten carbide button's ball tooth, fine finishining; Hard alloy spherical-teeth makes finished product through Making mold, sintering, compacting, grinding; Cutter shaft, cutter lid make finished product by blank forging, roughing, heat treatment, fine finishining; After each cleaning parts of hobboing cutter is clean, the outer ring of taper roll bearing 5 is respectively charged in the endoporus of cutter hub assembly 4; Left cutter lid 2 is connected as a single entity by arc step and cutter shaft 1, is loaded by a floating seal 3 in the chamber of left cutter lid 2, is installed on axle by the inner ring of taper roll bearing 5 simultaneously, and locates at the inner face of Zuo Daogai 2; Another floating seal 3 is loaded in the chamber of cutter hub assembly 4 left end, then cutter hub assembly 4 is installed on cutter shaft 1, this completes the installation of hob device left end; The inner ring of another set of bearing 5 is installed on axle, a floating seal 3 is loaded in the chamber of right cutter lid 7 simultaneously, another floating seal 3 loads in the chamber of cutter hub assembly 4 right-hand member, then right cutter lid 7 is installed on cutter shaft 1, screwed by the screw device on right cutter lid 7 and fix hobboing cutter parts, assembling so far completes.
