Description
Technical field
The present invention relates to the mechanical synchronizer of main driving motor of disc shear in the metallurgical machinery sector, the mechanical synchronization of main driving motor of disc shear when this mechanism is mainly used in metallurgy industry steel rolling product cut deal Runout area shearing steel plate width adjustment.
Background technology
At present, circle shear is a Medium and Heavy Plate Rolling Production line Runout area key equipment, be mainly used in the Fixed width of medium plate is sheared, and can be that the steel plate of 6-25mm carries out high-precision bilateral Fixed width and shears to thickness, the slitter edge of cutting-out is undertaken cataclasm by scrap cutter and collects.This equipment has advantages such as shear surface is straight, smooth, distortion is little, geometric accuracy is high, shear rate is fast.Circle shear is by fixedly cutting and moving to cut and form, by the transmission respectively of two main driving motors.For guaranteeing to shear the width accuracy of steel plate, need carry out mechanical synchronization between these two main driving motors, synchronous with the cutterhead shear rate that satisfies both sides.Fixedly cutting is to be fixed by bolts on the base, and locatees with steady pin.Move and to cut that be installed in can be on the slide that slides on the traversing base.When the width of shearing steel plate changes, move and cut and on traversing base, to adjust, to satisfy the Fixed width requirement.The mechanical synchronization of main driving motor of disc shear all adopt at present both at home and abroad directly with two motors with telescopic whole jaw universal coupling with spider couple together carry out synchronous.But there are many problems in this method; Especially it is more unfavorable to work as shear rate situation high and that shearing steel plate change width amplitude is bigger; Because when the shearing steel plate is narrow, this moment, the dynamic balancing of connecting axle can't guarantee, was very easy to occur dangerous; And, make the making of the synchronous connecting axle of this kind and processing all very difficult because the wide amplitude of fluctuation of plate is bigger.Therefore the mechanical synchronizer of developing a kind of novel main driving motor of disc shear is to be badly in need of the new problem that solves.
Summary of the invention
The purpose of this invention is to provide a kind of brand-new design, technology and manufacturing philosophy; Adopt the drum-shaped tooth type connecting axle of cycloidal planetary gear speed reducer and band intermediate supports seat to carry out two mechanical synchronization between the motor; Can guarantee to move and cut moving steadily freely when changing the cutterhead opening degree, and when high speed shear, can make two motors realize the mechanical synchronizer of the main driving motor of disc shear of secure synchronization running.
The objective of the invention is to realize like this: a kind of mechanical synchronizer of main driving motor of disc shear; Whole device is made up of shearing machine body, Hooks coupling universal coupling, main transmission reductor, braking shaft coupling, main driving motor, first crown gear coupling, mobile side-sway line pin gear speed reducer, fixation side cycloidal planetary gear speed reducer, fixation side rigidity synchronizing shaft, traversing base, slide, second crown gear coupling, splined shaft, intermediate support seat, spline housing and the 3rd crown gear coupling; Two main driving motors are elected the motor of two shafts as; And pass through the connection of first crown gear coupling at its output and move side-sway line pin gear speed reducer and fixation side cycloidal planetary gear speed reducer; The output of fixation side cycloidal planetary gear speed reducer links together through the end of first crown gear coupling with the fixation side rigidity synchronizing shaft that supports with two fixed bearing blocks; The other end of fixation side rigidity synchronizing shaft is connected with the 3rd crown gear coupling; The output that moves side-sway line pin gear speed reducer is connected with second crown gear coupling; Second crown gear coupling is connected with splined shaft, intermediate support seat, spline housing, the 3rd crown gear coupling; The intermediate support seat adopts rolling bearing supporting spline housing, and the head of splined shaft has can pull out in spline housing or the guider of indentation; The operation principle of this device is that the structure that moves the telescopic synchronizing shaft of side band intermediate support seat adopts the spline ways of connecting, and increases guider in the end; Its two ends all adopt the barreled tooth flank connector to be connected with relevant portion; Intermediate support seat place adopts rolling bearing supporting spline housing, can satisfy steadily traversing requirement like this, satisfies the requirement of transfer torque when shearing; Dynamic balancing when synchronizing shaft turns round in the time of can satisfying high speed shear is again avoided occurring dangerous.Because the shear rate of circle shear is higher, causes the rotating speed of main driving motor also very high, make the corresponding increase of rotating speed of the synchronizing shaft between two motors equally; And when the width of shearing steel plate hour, the splined shaft of scalable synchronizing shaft and spline housing are very easy to occur getting rid of the danger that flies when running up, for solving this difficult problem; Be employed in during design and respectively increase a cycloidal planetary gear speed reducer between motor and two synchronizing shafts; According to the requirement of different shear rates, select suitable speed reducing ratio, the rotating speed of synchronizing shaft is reduced; So both guaranteed high speed shear, guaranteed again that the synchronizing shaft of motor was not caused danger when motor runs up.
Main points of the present invention are its structure and operation principle.Its operation principle is that the structure that moves the telescopic synchronizing shaft of side band intermediate support seat adopts the spline ways of connecting, and increases guider in the end; Its two ends all adopt the barreled tooth flank connector to be connected with relevant portion; Intermediate support seat place adopts rolling bearing supporting spline housing, can satisfy steadily traversing requirement like this, satisfies the requirement of transfer torque when shearing; Dynamic balancing when synchronizing shaft turns round in the time of can satisfying high speed shear is again avoided occurring dangerous.Because the shear rate of circle shear is higher, causes the rotating speed of main driving motor also very high, make the corresponding increase of rotating speed of the synchronizing shaft between two motors equally; And when the width of shearing steel plate hour, the splined shaft of scalable synchronizing shaft and spline housing are very easy to occur getting rid of the danger that flies when running up, for solving this difficult problem; Be employed in during design and respectively increase a cycloidal planetary gear speed reducer between motor and two synchronizing shafts; According to the requirement of different shear rates, select suitable speed reducing ratio, the rotating speed of synchronizing shaft is reduced; So both guaranteed high speed shear, guaranteed again that the synchronizing shaft of motor was not caused danger when motor runs up.
The mechanical synchronizer of main driving motor of disc shear compared with prior art; Have the shear precision advantages of higher of novel science, adjustment convenient disassembly, the steady safety of run-in synchronism, long service life, motor synchronous control precision height, circle shear, will be widely used in the metallurgical machinery sector.
