Adaptive floating roller flexible support device

Abstract

The invention discloses an adaptive floating roller flexible support device, comprising at least two floating support mechanisms and a box body support mechanism, each of the floating support mechanisms includes a floating roller and can drive the floating roller radially Moving radial adjustment structures, all the radial adjustment structures are communicated with the box body support mechanism; the radial force of the floating roller will be transmitted to the box body support mechanism through the radial adjustment structure for adjustment, And it is transmitted to other radial adjustment structures and the floating rollers driven by the radial adjustment structures through the box body support mechanism, so that the other floating rollers can automatically adjust the force they bear in the radial direction. Compared with other supporting methods, the present invention has the good characteristics of high efficiency and energy saving, uniform load, automatic adjustment of radial bearing force, vibration reduction and noise reduction, and heavy load bearing.

Description

technical field [0001] The invention belongs to the technical field of ball mills, and in particular relates to a cylinder support device of a ball mill and other large-scale rotary equipment. Background technique [0002] Ball mills and other large-scale rotary equipment generally have the characteristics of high quality, strong impact during operation, and high operating energy consumption. With the increasingly strict requirements of energy saving, emission reduction and environmental protection, ball mills are developing in the direction of giant, automatic and complex, and higher standards are put forward for the performance requirements of the supporting device of the rotating cylinder. [0003] At present, the cylinder supports of large-scale rotary equipment are mainly divided into two categories, namely main bearing sliding support, sliding shoe support, and rolling support. The main bearing sliding support is used in various types of ball mills, and the sliding sho...

AI Technical Summary

Problems solved by technology

In terms of operating efficiency, the energy consumption of rolling support is obviously better than that of sliding shoe sliding support, but rolling bearing support cannot be used in large ball mills

No matter which type of support is rigid, the impact and vibration during operation will cause greater environmental noise pollution; due to the huge total weight of the loaded materials, grinding bodies and the cylinder inside the cylinder, it will cause a huge load-bearing to the support device pressure, and during the rotation process, the material and grinding body in the cylinder are in parabolic motion, and the throwing point is not the bottom of the cylinder, but the side, resulting in greater force on the bottom of the cylinder and lateral local support parts, and greater wear on the corresponding parts , this will lead to partial premature damage of the support device, resulting in high maintenance costs; the local load-bearing and the unbalanced load of the support device may not only cause local rotation wear, but also cause local crushing of the support device

Especially for roller support, due to the uneven force on the supporting rollers, the rolling bearings with line contact or point contact will fail prematurely
