Description
[technical field]
The present invention relates to pit kiln coke pusher technical field, a kind of vertical 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 be three grades of slowing-down structure: i=2.045 * 3.962 * 4.923=39.9, pushing ram gear Z=15, the m=40 of one-level cone tooth+secondary parallel-axes gears drive tooth bar realize pushing ram advance or retreat, coke pushing speed 27.4m/min, stroke 25774mm.
[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 vertical 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 make driving gear have certain amount of floating in order to sideshake and the bottom clearance of compensation with tooth bar with spending strong being slidingly connected, and long rack bar side is loaded on the pushing ram inwall.During according to paper " research of 6m vibration of pushing rod of coke oven " the reciprocal work done of pushing ram, pushing ram " waist collapses " deflection occurs up to 60mm, and its result makes gear-tooth bar sideshake and bottom clearance substantial deviation theoretical value (sideshake 3.5-5mm, bottom clearance 8-12mm): the anterior tooth bar sideshake 6.8-8mm of place of actual measurement pushing ram, bottom clearance 14.8-18mm.After the present invention will long rack bar side be loaded on the pushing ram inwall, its side dress section rigidity is far above sleeping dress section, long tooth bar deflection is descended, simultaneously according to Theoretical Calculation: establishing the tooth bar deflection is 30mm, coke pushing stroke 25774mm, then the pitch angle of tooth is 0.0012 ° only, illustrates that the sideshake of gear-tooth bar and bottom clearance still can be in theoretical value, guarantees the accuracy of mesh of gear-tooth bar, thereby gear-tooth bar stable drive greatly reduces the vibration of gear-tooth bar surging force and pushing ram;
(B) slow down with single-stage three Cycloidal Wheel and replace three grades of deceleration: 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 " 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 " cone tooth+secondary reducer with hardened tooth surface " (bearing capacity 72000Nm) is suitable with DCY-500 type reducer with hardened tooth surface (seeing JB/T9002-1999), 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 centre circle of gear pins 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; Cycloidal gear teeth and half imbedding needle pin can not break, thereby supporting capacity is large, and reliability is high.
[description of drawings] Fig. 1. embodiment of the invention structural representation
[embodiment] encyclopaedizes the present invention below in conjunction with accompanying drawing:
With reference to Fig. 1. a kind of vertical cycloid-tooth bar coke pusher, comprise coke pushing bearing 1, support roll 2, pushing ram 3 and transmission mechanism, described pushing ram 3 (comprises the coke pushing head, crawler shoe) is body structure, be bearing on the support roll 2, have in the support roll 2 three groups with the side roller to prevent pushing ram 3 sideslips, support roll 2 is connected in the bottom of coke pushing bearing 1, described transmission mechanism comprises rotor axis of electric 17 and is contained in first on the rotor spindle 17, two capacity eccentric bearings 11,14, Cycloidal Wheel, pin wheel housing 18, needle pin 19 and output mechanism, output mechanism comprises output shaft 6, pin 10 and column sleeve, described output shaft 6 is bearing in the endoporus of vertical support 8 by two bearings 7, it is characterized in that:
Described motor, pin wheel housing 14 and vertical support 8 are integrally togather in turn, output shaft 6 shaft extension end outer flower-keys and driving gear 8 internal splines are slidingly connected, make driving gear 8 have certain amount of floating in order to sideshake and bottom clearance between compensation and the long tooth bar 5, driving gear 8 and long tooth bar 5 engagements, described long tooth bar 5 sides are loaded on pushing ram 3 inwalls, when driving gear 8 turns clockwise, long tooth bar 5 promotes pushing ram 3 and moves forward, otherwise, when driving gear 8 turns counterclockwise, it is mobile backward that long tooth bar 5 promotes pushing ram 3, because long tooth bar 5 sides are loaded on pushing ram 3 inwalls and long tooth bar 5 very long (greater than the coke pushing stroke), therefore when " waist collapses " appears in pushing ram 3, the sideshake of gear-tooth bar and bottom clearance still can be in theoretical value, the inboard anchor ring upper joint of described output shaft 6 disks one dome 9 is used for covering bearing 7, purpose is to prevent that lubricating oil from entering bearing 7 and spilling from oil sealing, the identical Cycloidal Wheel 13 in both sides and 180 ° of middle Cycloidal Wheel 16 phase differential in the described Cycloidal Wheel, both sides Cycloidal Wheel 13 is taken turns half of Cycloidal Wheel 16 in the middle of wide the equaling, thereby the rotating mass on the input shaft is in statical equilibrium, dynamic equilibrium state, make transmission more steady, column sleeve 12,15 correspond respectively to Cycloidal Wheel 13,16, needle pin 16 half is embedded in the pin wheel housing 14, claim partly to bury toothing (Zhu Xiaolu " 828 pages of Gear Transmission Design handbook), make needle pin have very high bending force.
