Description
Technical field
The utility model relates to the power circle shear in steel finishing operation field, especially relates to a kind of circle shear based on becoming the transmission of centre-to-centre spacing gear pair.
Technical background
The full name of circle shear is metal-slitting machine.Circle shear is arranged on band steel finishing line conventionally, is used for the moving longitudinal edge with steel to trim or be cut into ribbon steel, make steel edge portion after cutting neat, accurately, without burr.The blade of circle shear is the disk of upper and lower two rotations, thereby steel plate or the steel band can continuous vertical to shearing motion.Blade is fixed on the overhanging end of cutter shaft.When shearing, the rotation of circle shear cutter shaft, the linear velocity of knife cut point equals to do continuous circular motion with the movement velocity of steel, has formed a pair of shearing without end points.
By the kind of drive, circle shear can be divided into drawing to cut with power to be cut.Draw that to cut be that the rotation of blade does not have transmission device, by before cutting, cut the equipment such as backward pull roller and band is pulled through to circle shear shears.Power is cut has independently motor independently to rotate as power source.Shear transmission system and make cylinder blade realize movement at the uniform velocity relatively, go up bottom knife constant speed and rotate.For ensureing that upper bottom knife is in strict accordance with constant-speed ratio transmission, conventionally adopt a power source to drive the cutter shaft of bottom knife simultaneously.
Blade overlap adjusting system (being worm gear device) can be according to the lap of bottom knife in the parameter adjustments such as belt steel thickness.Conventionally adopt spiral lift or upper cutter shaft (or lower cutter shaft) overcoat excentric sleeve, the structures such as adjustment excentric sleeve angle (another cutter shaft radial direction is fixed) realize cutter and depress (or bottom knife presses) adjustment, the i.e. adjustment of lap.
Blade side to clearance adjustment mechanism (being worm gear device) according to the sideshake of bottom knife in the parameter adjustment such as belt steel thickness and intensity.Conventionally pass through along cutter shaft under axis vibration (or upper cutter shaft), another cutter shaft is motionless along axis direction, to realize the adjustment of blade lateral space self.
Therefore, upper and lower cutter shaft axis centre is apart from being that variation is adjustable, needs to realize to become centre-to-centre spacing, constant speed ratio (angular speed ratio is 1), transmission that rotation direction is contrary.For realizing this requirement, in engineering application, mainly adopt two kinds of versions (the following cutter shaft of following explanation can be adjusted blade lateral space self along axis vibration, and upper cutter shaft moves up and down and adjusts blade lap is example explanation, and vice versa):
(1) by idle wheel transmission: be followed successively by from top to bottom upper cutter shaft, axle of carrier pulley, power shaft, lower cutter shaft (axis is not in same vertical guide), gear is all housed on each axle.Gear on power shaft, engages with the gear on lower cutter shaft, the gear on axle of carrier pulley respectively, and the gear on axle of carrier pulley also engages with the gear on upper cutter shaft.Wherein the axial location of power shaft, lower cutter shaft is fixed, and upper cutter shaft axial location requires to adjust its position according to blade lap, and according to gear, engagement requires to adjust its position to axle of carrier pulley.Upper cutter shaft axial location requires adjusted position postpone according to blade lap, adjusts the position of axle of carrier pulley, ensures that the gear centre distance on the gear on axle of carrier pulley and gear, the upper cutter shaft on power shaft is constant, realizes correct engagement.The shortcoming that this structure exists has: 1. gear wheel-train is more complicated, for realizing the reverse rotation of upper and lower cutter shaft, has set up two idler gears (being the gear on axle of carrier pulley and power shaft); 2. axle of carrier pulley position accuracy demand is high, and position regulator is more complicated.3. whole transmission mechanism radial dimension is large, and transmission case body size is large.
(2) adopt Belt Drive: be followed successively by from top to bottom cutter shaft, lower cutter shaft, steering spindle one (working to increase flat rubber belting cornerite), steering spindle two (band tensioning function), belt pulley is all housed on each axle, and wherein descending cutter shaft is power shaft.Belt canoe: forward is wound around the belt wheel on upper cutter shaft, then the belt wheel on cutter shaft under reverse-winding, and then forward is wound around the belt wheel in steering spindle one, and forward is wound around the belt wheel in steering spindle two, finally gets back to the belt wheel place on cutter shaft.Wherein descend the axial location of cutter shaft, steering spindle one to fix, upper cutter shaft axial location requires to adjust its position according to blade lap, and steering spindle two requires to adjust the position of axis according to belt tension, realize the tensioning of belt.The shortcoming that this structure exists has: 1. belt wheel train is more complicated, and for realizing the reverse rotation of upper and lower cutter shaft, flat rubber belting is two-way winding on belt wheel, and belt is subject to compound bending, and belt life is short and change difficult; 2. be with the flexible slip of transmission, can not ensure changeless gearratio; 3. be with transmission efficiency lower (gear drive relatively), single-stage band transmission efficiency 90% left and right; 4. larger to the pressure ratio of axle after belt tensioner pulley device.
