Abstract
The utility model relates to a force transmitting which adjusts the bending of rollers caused by loads and self weight and the line pressure distribution between two rollers by a method of exerting adjustment bending moment on the supporting points of the pressing rollers which work in pairs. The utility model provides two lever force enclosed type bending adjusting mechanisms which are arranged in an axial mode and a radical mode along the rollers, the two lever force enclosed type deflection adjusting mechanisms can exert simultaneously equal or unequal adjustment bending moment on the supporting points of both ends of the rollers which work in pairs under the situation that a support seat bears no additional load. The bending adjusting mechanism for the rollers working in pairs can be widely used for the press section of a paper making machine, a roll machine for sheet metal and other similar devices.
Description
The utility model is a kind of force transmission mechanism.The amount of deflection that the squeezing roller that can be used for regulating in paper machine, the sheet metal roller mill work in pairs produces because of the effect of deadweight and load.
The pressure roller of work are when pressurization in pairs, because of being subjected to the effect of linear pressure and dead weight between two rollers, roller generation deflection deformation makes gap and line pressure distribution between roll surface become inhomogeneous, makes by the material to be machined between two roll surfaces and be subjected to uneven extruding and distortion on banner direction.Press section at paper machine causes by the inhomogeneous dehydration and the distortion of paper web therebetween, finally makes the paper web uneven drying, and quality of finished paper descends.
Usually roller, mandrel roller or crown controlled roll waited the harmful effect that reduces or eliminates the roller deflection deformation admittedly in height, the adapted during the employing roll surface ground on paper machine.Wherein high method is the easiest, economical in the roll surface mill, has obtained general application.The middle height that it is good that the shortcoming of this method is mill immobilizes, and only is adapted to a certain fixing work line pressure, in the work can not to the middle high value of roller and in high curve adjust, thereby can not satisfy the technological requirement that changes linear pressure size and distribution in the work.Solid roller, mandrel roller, particularly crown controlled roll can satisfy the requirement that process conditions change preferably in the employing on the broadsheet machine, can adapt to the variation of work line pressure and control the amount of deflection of roll surface neatly.But in the weight of solid roller, mandrel roller and crown controlled roll big; Structure is complicated; Make difficulty; Cost is high.Proposed to apply the mechanism of the method adjustment and the deflection deformation of compensation roll surface of moment of flexure in the patents such as Russian Patent 455181 to single roller fulcrum.This patent adopts a pull bar and roller to be arranged in parallel, and roller is connected with lever with the pull bar two ends, and pull bar is that an inside can lead to the hollow tube that cooling water, peripheral insulating barrier hold resistive heater outward.Adjust heating current and cooling water inflow, can accurately control the pull bar variations in temperature, cause that pull bar is flexible and produce thermal stress, this power becomes moment of flexure by a pair of lever that connects roller and pull bar and acts on the roller bearing, makes roller generation deflection.The described roller deflection adjusting device of this patent can only be regulated single roller amount of deflection, and when applying moment of flexure adjusting amount of deflection, also can produce bigger additional axial force in roller bearing.Bearing load is strengthened, and power consumption increases, and the life-span reduces.
The purpose of this utility model is to provide a kind of two ends fulcrum of two pressure roller to paired work to apply the force-closed formula amount of deflection governor motion of regulating moment of flexure simultaneously.
The utility model is considered, the amount of deflection direction of the roller of work generation when work is opposite in pairs, for offsetting the amount of deflection of two rollers simultaneously, the afterburning member of the adjusting moment of flexure that is applied to two roller the same sides is connected with a lever system, and make the adjusting moment of flexure that is applied on two roller the same side fulcrums have opposite direction.So just can make reaction force that two roller fulcrums regulate moment of flexure balance and be not delivered to bearing and get on mutually voluntarily, realize regulating moment of flexure---the sealing of fulcrum power.
Compared with the prior art, the utlity model has following advantage:
1. can regulate two roller amounts of deflection of paired work simultaneously.
2. can be according to technological requirement, the adjusting moment of flexure of applying equal and opposite in direction or not waiting for roller two ends fulcrum is regulated symmetry or asymmetric deflection deformation that the roller both sides produce.
3. can adopt in the roll surface mill high and apply the method for regulating moment of flexure and eliminate the roller amount of deflection simultaneously.Governor motion is simple, and it is convenient to regulate, and adjustable range is big, effective, and can control on the spot or concentrated remote control by control system.
4. whole active forces of produce regulating moment of flexure are balance voluntarily in mechanism all, can not be delivered to bearing and get in the basis, also can not cause additional load and increase frictional force and power consumption in the bearing.
Below in conjunction with accompanying drawing the utility model is described further:
Fig. 1, Fig. 2 are first embodiment of the present utility model, and Fig. 1 is a front view, and Fig. 2 is a right side view.
Fig. 3, Fig. 4 are second embodiment of the present utility model, and Fig. 3 is a front view, and Fig. 4 is a right side view.
In first embodiment, governor motion adopts axial arranged.Air pressure in the pneumatic bellows (5) is through its end cap (4), act on respectively on 8 screw pins (6) that connect 4 pairs of active levers (3) and pneumatic bellows end cap (4), transmission through the active lever system is amplified, form two pairs of equal and opposite in directions, couple that direction is opposite, act on the bearing block (8) of roller (1) up and down, pass through rolling bearing (7) again and be delivered on the roller (1), implement the amount of deflection of roller is regulated.The place of interconnecting of fastener (2), active lever (3) and pneumatic bellows end lid (4) all adopts and is movably hinged, and the hinged place of active lever (3) all has slotted hole, to adapt to the variation of two pitchs of holes.Fastener (2) can be dismantled easily with the hinged place of active lever (3), so that mechanism separates, changes blanket, roll change and other technological operations.
In second embodiment, two end caps (4) angled and affixed levers of external part (9) at pneumatic bellows (3) two ends are affixed with bolt, air pressure in the pneumatic bellows (5) is delivered to respectively on two affixed levers (9) through its end cap, act on again on the bearing block (8) of two rollers (1), act on the roller (1) through rolling bearing (7).The affixed lever of two couple of two rollers (9) links to each other with a pair of profile of tooth connecting plate (10) by bearing pin (11) up and down, all have slotted hole on two connecting plates and use bolt (12) to connect, adjust the total number of teeth in engagement of profile of tooth connecting plate (10) and spacing that loose bolts (12) can be adjusted two rollers (1) easily and mechanism is thrown off, so that change blanket, roll change and other technological operations.In the present embodiment pneumatic bellows end cap (4) is switched the installation site, can carry out reciprocal amount of deflection to roller and regulate.
In the utility model, the dynamic component that produces active force can be a pneumatic bellows, also can adopt pneumatic diaphragm cylinder, cylinder, hydraulic cylinder, bolt and nut pair etc. as the power original paper.
