Roller body flexible deformation correction device

Abstract

The invention discloses a roller flexible deformation correction device which comprises a barrel. An air compressor is fixedly installed in the barrel. An outlet of the air compressor is connected with air cylinder bodies. The air cylinder bodies are evenly arranged on the circumference of the outer wall of the barrel. Piston rods of the air cylinder bodies are connected with ejector rods. Hollow supporting barrels are evenly installed on the outer wall of the barrel circumferentially. Springs are sleeved with the supporting barrels. The supporting barrels are provided with supporting rods in a matched mode. One end of each supporting rod is inserted in the corresponding supporting barrel and makes contact with the corresponding spring and the other end of each supporting rod is connected with a balance ring. The balance rings are provided with U-shaped grooves used for installation of balance rods. The roller flexible deformation correction device can be stably installed inside a roller and used for correcting flexible deformation of the roller, so that flexible deformation correction accuracy of the roller is improved.

Description

technical field [0001] The invention relates to a roll body flexible deformation correction device, in particular to a roll body flexible deformation correction device for correcting the roll body flexible deformation. Background technique [0002] The roll body is an indispensable device in various large-scale equipment, such as paper machines, ball mills, etc., and with the improvement of production efficiency, the diameter of the roll body in paper machines, ball mills, etc. is getting larger and larger. In order to ensure that the equipment Safe operation requires that the rollers rotate with as little deflection at the center as possible, so that the processing quality can be guaranteed without causing harmful vibrations. [0003] At present, the traditional two-stage dynamic balancing method for large-diameter rollers cannot eliminate the deflection at the center of the rollers, and because the rollers have large diameters and high rotational speeds, the balancing devi...
