Abstract

The utility model discloses a device for correcting flexible deformation of a high-speed large-diameter rotating roller body. The device comprises an internal ring, wherein the internal ring is provided with 12 circular tubes; one end of each support ring is placed into the inner wall of each tube on the internal ring; six round steel rods are uniformly arranged on the external circle of the internal ring; an internal hole of one end of each round steel rod is a threaded hole; one end of each support rod is provided with an external thread; the external thread at one end of each support rod is arranged in the threaded hole of each round steel rod on the internal ring; the support rods are rotated to move up and down along the round steel rods on the internal ring; springs are arranged on the circular tubes on the support rings; and U-shaped grooves for accommodating balance rods are formed on the support rings. A balance device is arranged at the middle position of the roller body, the support rings on the balance device are pressed against the inner wall of the roller body, in the process of making dynamic balance, the balance rods with certain length are arranged in the U-shaped grooves on the support rings of the balance device, and under the action of spring force, the balance rods are pressed against the inner wall of the roller body and rotate together with the roller body in the working process. By the device for correcting the flexible deformation of the high-speed large diameter rotating roller body, the flexible deformation of the roller body can be effectively eliminated, and the fault rate of the operation of a paper machine can be reduced.

Description

A kind of device of proofreading and correct high speed major diameter rotation roll body flexible deformation

Technical field

The utility model relates to the paper machine technology field, is specifically related to a kind of device of proofreading and correct high speed major diameter rotation roll body flexible deformation.

Background technology

Because the speed of a motor vehicle of paper machine constantly increases in recent years, the rotation roller diameter in the paper machine is increasing, and for paper machine operation failsafe, the amount of deflection of center is as far as possible little when rotated to require roller, so just can not cause nuisance vibration.

At present; The roller that diameter is big adopts two sections traditional dynamic balance methods can't eliminate the amount of deflection at roller center place, and because roller diameter is big, speed is high; The bascule that installs additional in the middle of the roller must be fixed, when roller rotates can not and the roll body inwall between produce relative motion.

Summary of the invention

In order to overcome the shortcoming of above-mentioned prior art, the purpose of the utility model is to provide a kind of device of proofreading and correct high speed major diameter rotation roll body flexible deformation, and is simple and reliable for structure, is applicable to the roll body of diameter range 1000mm～2000mm.

For the attainment of one's purpose, the technical scheme taked of the utility model is:

A kind of device of proofreading and correct high speed major diameter rotation roll body flexible deformation, ring 1 has 12 circular pipes in comprising on the interior ring 1; Tube wall in support ring 3 one ends are put on the ring 1; On interior ring 1 cylindrical six round steel of evenly arranging are arranged, round steel one end endoporus is a screwed hole, and support bar 7 one ends are external screw thread; In the round steel screwed hole in support bar 7 one end external screw threads are contained on the ring 1; Rotation support bar 7 makes along the round steel on the interior ring 1 and moves up and down, and spring 4 is contained on the circular pipe on the support ring 3, and the U-lag that haltere 5 is installed is arranged on the support ring 3.

The beneficial effect of the utility model is: can effectively eliminate the flexible deformation of roll body, make major diameter roller also can under at a high speed, rotation steadily reduce the fault rate of paper machine operation.

The specific embodiment

Below in conjunction with the accompanying drawing and the specific embodiment the utility model is elaborated.

With reference to Fig. 1-1, Fig. 1-2, a kind of device of proofreading and correct high speed major diameter rotation roll body flexible deformation is made up of interior ring 1, pin 2, support ring 3 and spring 4; On the interior ring 1 12 circular pipes are arranged, the tube wall in support ring 3 one ends are put on the ring 1 just can slide up and down; On interior ring 1 cylindrical six round steel of evenly arranging are arranged, round steel one end endoporus is a screwed hole, and support bar 7 one ends are external screw thread; In the round steel screwed hole in support bar 7 one end external screw threads are contained on the ring 1; Rotation support bar 7 can make along the round steel on the interior ring 1 and move up and down, and spring 4 is contained on the circular pipe on the support ring 3, and the U-lag that haltere 5 is installed is arranged on the support ring 3.

The operation principle of the utility model is:

With reference to Fig. 2; The cross sectional shape of haltere 5 is hexagons, and the external diameter of bascule is less than the internal diameter of roll body, at this moment under the effect of pin 2; With the bascule roll body centre position of packing into; And take off pin 2 from bascule, under the effect of spring 4, the support ring 3 on the bascule just withstands on the roll body inwall.Make it tightly withstand on roll body inwall to inner rotary support bar 7 this moment, and fastening nut 8 prevents that support bar 7 from rotating, like this under the acting in conjunction of spring 4 and support bar 7; Bracing or strutting arrangement just is fixed on roll body inside securely, has both made roller diameter greater than 1000mm, and rotary speed is during greater than 2000m/min; Bracing or strutting arrangement also can rotate with roll body together, can be in the roller slides within, when doing dynamic balancing; According to the data of dynamic balance running, utilize the hole of specific purpose tool through roll body 6 two ends that the haltere 5 of certain-length is contained in the U-lag on the bascule support ring 3, under the effect of spring force; Haltere 5 just withstands on roll body 6 inwalls, rotates with roll body during work.
