Abstract
The invention relates to a triaxial power balance device used for a high-speed tube cold rolling mill. The triaxial power balance device is characterized in that a driving shaft, a crank shaft, a balance shaft, a small balance block, a large balance block, a transmission gear, a crank pin and a rack are included; the triaxial power balance device is connected with the rack through a connecting bar. When the tube cold rolling mill of the triaxial power balance device provided by the invention runs, six balance blocks at both sides of a central line are used for balancing the inertia force of the rack and the centrifugal force between the balance blocks, thereby not only greatly reducing the acting force exerted by the inertia force generated in the operation of machines to the device and the device base, increasing the speed of alternate motion of the mill and increasing the productivity for the rolling mill, but also reducing the investment cost for construction of the device.
Description
Technical field
The present invention relates to a kind of dynamic balancer, particularly disclose three dynamic balancers on a kind of high speed cold tube-rolling mill.
Background technology
With reference to the pattern manufacturing of the cold tube-rolling mill of the former Soviet Union, its driven equilibrium device adopts simple crank block tactic pattern, no counterweight to the cold tube-rolling mill of China for a long time.Along with the per minute of cold tube-rolling mill frame moves back and forth increasing of number of times, the foundation of civil work that the inertia force of milling train work housing increases greatly, the bearing of this inertia force by crank axle is passed to equipment gets on, and the per minute that has limited the frame of two roller cold tube-rolling mills moves back and forth the raising of number of times.The production efficiency of leading is low.The KPW50LC type of present German SMS MeeR company and two roller cold-rolling mills of KPW75LC type adopt four balance weights to come the inertia force of balance work housing, but this balance mode produces the moment loading of a pair of alternation repeatedly inevitably on Equipment Foundations, the vibration of foundation is bigger, thereby foundation of civil work is had relatively high expectations.KPW50DMR (K) is to adopt four balance weights to come the inertia force of balance work housing with KPW75DMR (K) type two roller cold tube-rolling mills equally, but adopt the pattern of two limit balance weight reversed arrangement, the moment of alternation repeatedly and the torque of generation are all born by casing, do not bear by Equipment Foundations and do not resemble LC type milling train.The moment of inertia that the pattern that two roller cold tube-rolling mills of KPW18HMR (K) type and KPW25HMR (K) type adopt Gear Planet Transmission to add the complete equipilibrium of counterweight is come the inertia force and the rotary main shaft of balance work housing, balance quality is good, vibrate little, but this pattern only is only applicable to little work housing weight, thereby only is only applicable to the cold tube-rolling mill of type specification.KPW100VMRK adopts the slide block direction of balance slide block to become 90 ° VE with the glide direction of frame with KPW125VMRK type two roller cold tube-rolling mills, the balance weight of the milling train of this pattern is the inertia force that produced of balance frame weight and slide block weight preferably, and balance moment of inertia on the most crank axle, but need very dark very expensive foundation of civil work.
France Vallourec company relies on the inertia force that centrifugal weights is come balance milling train work housing is installed on the power transmission shaft, but for avoiding producing a pair of bigger moment of alternation repeatedly, a pair of travelling gear and centrifugal weights adopt vertical layout, and a pair of travelling gear of two roller cold tube-rolling mills and the centrifugal weights that do not resemble German SMS MeeR adopt horizontally disposed pattern.
The domestic cold tube-rolling mill of China is a same position except large-sized rolling mills adopts crank-pin, but the glide direction of balance slide block becomes the design of 90 ° VE to also have outward when work housing is in preceding (back) extreme position balance slide block to be in the design of horizontal equilibrium in the centre position of stroke with the frame glide direction, this design is because the inertia force of horizontal equilibrium milling train work housing and slide block can not get good balance, so the rotating speed of crank axle is lower.The milling train of other pattern does not structurally all have the bascule of work housing inertia force, thereby can only be the cold tube-rolling mill of low-speed running.
Summary of the invention
The objective of the invention is to provide a kind of novel dynamic balancer, disclose three dynamic balancers on a kind of high speed cold tube-rolling mill, to improve the productivity ratio of milling train.
The present invention is achieved in that three dynamic balancers (hereinafter to be referred as three dynamic balancers) on a kind of high speed cold tube-rolling mill, it is characterized in that three dynamic balancers comprise driving shaft, crank axle, trunnion shaft, little balance weight, big balance weight, travelling gear, crank-pin and frame, are connected with frame by connecting rod.The parts that its medium and small balance weight and travelling gear are formed by connecting are contained in the center line both sides of driving shaft, and the two ends of driving shaft are contained on the bearing; The parts that big balance weight and travelling gear are formed by connecting are contained in the center line both sides of crank axle, and crank axle is installed on the bearing; The parts that little balance weight and travelling gear are formed by connecting are contained in the center line both sides of trunnion shaft, and trunnion shaft is installed on the bearing.Crank-pin is installed in the pin-and-hole on the parts that big balance weight and travelling gear be formed by connecting, and is connected with an end of connecting rod, and the other end of connecting rod is connected with work housing by pin.Described travelling gear meshes each other, and large and small balance weight place in a straight line.All travelling gears, balance weight, crank-pin and bearing are installed in the transmission balance box.In three dynamic balancers, its planform of described balance weight is: big balance weight is general sector structure, and little balance weight is the sector structure of middle band concave arc shape, so that shorten casing length, reduces the diameter of travelling gear.
Three dynamic balancers of the present invention compared with prior art, its main feature is: after 1, adopting three dynamic balancers, balance work housing inertia force in the horizontal direction not only when crank turns to each position, and also balance mutually of the centrifugal force between the vertical direction balance weight, thereby frame inertia force is to the active force of equipment and Equipment Foundations when significantly reducing the machine high-speed motion, improve the reciprocating motion speed of machine, also just improved the productivity ratio of milling train.
2, owing to alleviated the vibration on transmission tandem-driving bogie casing and basis thereof, make the transmission of machine more steady.
3,, thereby can reduce the investment cost of equipment foundation of civil work owing to alleviated active force to equipment and Equipment Foundations.
