Description
[technical field]
The present invention relates to pit kiln coke pusher technical field, a kind of horizontal cycloid-rack drives coke pusher.
[background technology]
Coke oven factory of Baogang paper " research of 6m vibration of pushing rod of coke oven " points out: can produce vibration during the reciprocal work done of pushing ram in the coke pusher, its major cause is the distortion that " waist collapses " trend is progressively arranged after pushing ram is heated, and the pushing ram distortion makes gear-tooth bar sideshake and bottom clearance substantial deviation theoretical value (sideshake 3.5-5, bottom clearance 8-12): the anterior tooth bar sideshake 6.8-7.2 of place of actual measurement pushing ram, bottom clearance 14.8; Middle part sideshake 7.5-7.8, bottom clearance 18; Rear portion sideshake 7.6-8, bottom clearance 17.2 (units: mm).
Vibrating in various degree all appears in the 6m coke oven coke-pusher bar of domestic Baosteel, Wuhan Iron and Steel Plant, Handan Iron and Steel Co, elder brother's steel, mountain Jiao and Baogang etc., produce resonance when serious and cause that bottom brick becomes flexible, cracks, the positive displacement of jamb brick and combustion chamber string leak etc. (6m coke oven principal dimension: the long 15140mm of coking chamber, high 5650mm, average wide 450mm);
Coke pusher comprises pushing ram, coke pushing bearing and transmission mechanism: motor YZR355L110kW, n
1=582rpm, n
2=14.6rpm, pushing ram (comprising coke pushing head, crawler shoe) is bearing in above the support roll, have in the support roll three groups with the side roller to prevent the pushing ram sideslip, pushing ram is a body structure, tooth bar is located at the top of bar, in pushing ram enters stove after, in order to support pushing ram, be provided with crawler shoe, its bottom height is adjustable.Adopt magnetic eddy-current brake WZ355L and hydraulic pressure block brake YWZ-400/90-10 to carry out the speed setting of coke pushing whole process to realize without impacting coke pushing.For pushing ram in the anti-incinerator that has a power failure suddenly, be provided with hand gear.
Transmission mechanism is " cone tooth+secondary reducer with hardened tooth surface " three grades of deceleration: i=2.045 * 3.962 * 4.923=39.9 gear-tooth bars (m=40), realizes pushing ram forward and back, coke pushing speed 27.4m/min, stroke 25770mm.
[summary of the invention]
Gear-tooth bar stable drive, pushing ram did not vibrate and low with price, that efficient is identical single-stage cycloidal replaces the horizontal cycloid of background technology-rack drives coke pusher when the object of the invention provided a kind of work done.
Technical scheme:
(A) driving gear and output shaft are with spending strong being slidingly connected, make driving gear have certain amount of floating in order to sideshake and the bottom clearance of compensation with tooth bar, long and narrow tooth bar places the corresponding elongated slot of pushing ram, running fit, the tooth bar bottom supporting is on slide roller, slide roller is connected in the pushing ram bottom, therefore in the reciprocal work done of pushing ram, when " waist collapses " distortion appears in pushing ram, owing to tooth bar is not to be fixed on to make tooth bar can not produce moderate finite deformation on the pushing ram, the sideshake of gear-tooth bar and bottom clearance still are in theoretical value and guarantee the accuracy of mesh, and the steady transmission of gear-tooth bar greatly reduces the vibration of gear-tooth bar surging force and pushing ram.
(B) with the efficient of single-stage cycloidal: Zhu Xiaolu " 6 pages of Gear Transmission Design handbook, " 1-12 page or leaf on the gear handbook: cycloid efficiency eta=0.9～0.98 ≈ 0.94, thereby can replace background technology " cone tooth+secondary reducer with hardened tooth surface ".
According to background technology, its creativeness is embodied in [beneficial effect]:
(1) in the reciprocal work done of pushing ram, guarantees the gear-tooth bar accuracy of mesh, greatly reduce the vibration of surging force and pushing ram;
(2) background technology bearing capacity 72000Nm and DCY-500 type reducer with hardened tooth surface (seeing JB/T9002-1999) are suitable, 113930 yuan of the heavy 4340kg of machine, prices; Weight saving 45-60% of the present invention, price can reduce 50-65%.The Theoretical Calculation data are as follows: the center circle radius R
z=275, contact coefficient Y
Lmax=1.43, B=21,42
Contact stress σ
Jmax=(8914/R
z) { Y
LmaxT

0.5=1605 (MPa)
Allowable contact stress [σ
H]=1617 (MPa) (HB600-600) (see Xu Hao " mechanical design handbook " volume 1.4-289 page or leaf);
(3) breast wheel thickness is both sides uniform thickness wheel twices, 180 ° of the two phase differential, thereby the rotating mass on the input shaft is in statical equilibrium, dynamic equilibrium state, makes transmission more steady; The gear teeth and half imbedding needle pin can not break, thereby supporting capacity is large, and reliability is high.
