A device for correcting the flexible deformation of the rotating roller body with a balancing device

Abstract

The invention discloses a device for correcting the flexible deformation of a rotating roller body and equipped with a balance device. It includes a cylinder body. The outer wall of the cylinder body is provided with a hollow ejector rod along the circumferential direction, and the ejector rod is connected with a support rod through a screw thread. , the end of the support rod is connected with an arc-shaped support plate; the oil pump and the oil tank are fixedly installed inside the cylinder, the inlet of the oil pump is connected to the oil tank, the outlet of the oil pump is connected to the inlet of the diverter valve, and the outer wall of the cylinder is evenly installed with diverter valves along the circumferential direction. The piston cylinder with the same number of valve outlets, the liquid inlet of the piston cylinder is connected with the outlet of the diverter valve, the liquid outlet of the piston cylinder is connected with the oil tank, the piston rod of the piston cylinder is connected with a support ring, and the support ring is used to communicate with the valve. A pressure sensor is installed on the contact surface of the roller body, and an installation groove for installing a balance bar is also arranged on the supporting ring. The invention can ensure the bonding stability between the balance bar and the inner wall of the roller, and eliminates the problem that the accuracy of correction is affected by the centrifugal force.

Description

technical field [0001] The invention relates to equipment for correcting the flexible deformation of a roller body, in particular to a device for correcting the flexible deformation of a rotating roller body with a balancing device. 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 ...

AI Technical Summary

Problems solved by technology

[0007] The present invention aims to solve the correction accuracy caused by the low bonding stability between the balance bar and the inner wall of the roller under the action of the centrifugal force caused by the high-speed rotation of the roller body in the existing device for correcting the flexible deformation of the rotating roller body. low problem, and provide a device for correcting the flexible deformation of the rotating roller body with a balance device, which can ensure the stability of the fit between the balance bar and the inner wall of the roller, and prevent the effect of centrifugal force from affecting the accuracy of the correction
