Description
[technical field]
The present invention relates to the coke pusher technical field, a kind of vertical braking moment is from increasing few teeth difference-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 few teeth difference replaces the vertical braking moment of background technology from increasing few teeth difference-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) replace three grades of decelerations with the deceleration of single-stage involute less tooth difference: " the calculated example of 7-126 page or leaf on the gear handbook: efficiency eta=0.944 (two teeth difference Z
d=2), the contriver is according to 100 examples, tooth difference Z
d=2,3,4, calculation result draws: efficiency eta=0.934,0.96,0.97..Thereby can replace " cone tooth+secondary reducer with hardened tooth surface ";
(C) two groups of steel ball V-type slot devices in the brake component are steel ball V-type groove automatic pressurizing device improved (seeing 90 pages of Ruan Zhongtang " mechanical stepless transmission "): first group is comprised of the steel ball between active V-type slotted disk, the driven V-type slotted disk of telophragma one side and two V-type groove faces, and telophragma connects with the cone dish; Second group of steel ball by telophragma opposite side active V-type slotted disk, the second driven V-type slotted disk and two V-type groove faces centre forms.Principle of work: during energising, first group of active V-type groove face produces positive pressure to steel ball, and its axial component promotes the driven V-type slotted disk of telophragma separates friction pair, and braking moment disappears, and its circumferential component drives the output shaft work done that connects with second group of driven V-type slotted disk; During outage, the input shaft stop, moment of resistance makes the second driven V-type groove face produce positive pressure to steel ball, and its axial component compresses friction pair, and braking moment will muchly have much.
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: Z
