Roller body flexibility correction device with balancing device

Abstract

The invention discloses a roller body flexibility correction device with a balancing device. The roller body flexibility correction device comprises a center cylinder, wherein an air compressor is fixedly mounted in the center cylinder; cylinder bodies are uniformly distributed on the outer periphery of the center cylinder; each cylinder body is divided into a mounting part and a telescopic part through a partition board; an air cylinder body is mounted in each mounting part; the air outlet of the air compressor is connected with the air cylinder bodies; the piston rods of the air cylinder bodies penetrate through the partition boards to enter the telescopic parts; a telescopic hole is formed in each telescopic part and takes the shape of a circular truncated cone in whole, the caliber of the upper end of each telescopic hole is small and the caliber of the lower end of each telescopic hole is large; carrier rods matched with the telescopic holes and connected with the air cylinder bodies are arranged in the telescopic holes; hollow support cylinders are uniformly distributed and mounted on the outer walls of the cylinder bodies in the peripheral direction; springs are mounted in the support cylinders in a sleeving manner; the support cylinders are equipped with support rods; one ends of the support rods are inserted into the support cylinders and are in contact with the springs; the other ends the support rods are connected with balance rings; mounting grooves used for mounting balance rods are formed in the balance rings. The roller body flexibility correction device can be firmly mounted in the roller body for correcting the flexible deformation of the roller body, and improves the correction accuracy of flexible deformation of the roller body.

Description

Technical field [0001] The invention relates to a roll body flexibility correction device, in particular to a roll body flexibility correction device with a balance device for correcting the roll body flexibility and deformation. Background technique [0002] Rollers are indispensable devices in various large-scale equipment, such as paper machines, ball mills, etc., and with the improvement of production efficiency, the diameter of rolls in paper machines, ball mills and other equipment is getting larger and larger. In order to ensure the equipment Safe operation requires that the deflection at the center of the roller is as small as possible when rotating, so as to ensure the processing quality without causing harmful vibration. [0003] At present, the traditional two-stage dynamic balancing method for rollers with large diameters cannot eliminate the deflection at the center of the rollers, and due to the large diameter of the rollers and the high speed of rotation, the balance...
