Large-scale rotary cylinder support ring structure, dismounting tool of large-scale rotary cylinder support ring structure and using method of dismounting tool

Abstract

The invention discloses a large-scale rotary cylinder support ring structure, a dismounting tool of the large-scale rotary cylinder support ring structure and a using method of the dismounting tool, relates to a large-scale cylinder connection structure, in particular to the large-scale cylinder support ring structure, the dismounting tool of the large-scale rotary cylinder support ring structureand the using method of the dismounting tool, and provides a large-scale cylinder support ring structure with good reliability, the dismounting tool of the large-scale rotary cylinder support ring structure and the using method of the dismounting tool. Axial stairs are arranged on the outer wall of a rotary cylinder; a support ring penetrates through the first stair and is in interference fit withthe stair surface of the second stair; the side wall of the support ring is butted on the side surface of the third stair. According to the large-scale cylinder support ring structure, the dismounting tool of the large-scale rotary cylinder support ring structure and the using method of the dismounting tool, the connectivity between the support ring and the cylinder is ensured, and the mounting coaxality of the support ring is ensured.

Description

technical field [0001] The invention relates to a large-scale cylinder connection structure, in particular to a large-scale rotary cylinder support ring structure, its disassembly and assembly tool and its working method. Background technique [0002] The large cylinder mainly refers to the leading equipment of the paper mill "shredder", the leading equipment of the cement manufacturing plant "ball mill" and so on. especially important. The conventional large-scale stainless steel rotary equipment and the support ring are welded by welding, but after long-term use, the welding seam will fatigue and rupture, resulting in poor connection reliability. Therefore, at present, the form of interference fit is mostly used, that is to say, the inner diameter of the support ring is smaller than the outer diameter of the cylinder, and special tools need to be used to squeeze it in during installation, or the support ring is added by using the characteristics of thermal expansion and c...

AI Technical Summary

Problems solved by technology

However, for large cylinders, since the diameters of both the cylinder and the support ring are large, it is very likely that the support ring will be skewed after cooling, which will cause the support ring to be out of axis with the cylinder, affecting subsequent use

In addition, when the support ring needs to be repaired and disassembled, the traditional disassembly method will definitely cause damage to it. Whether it is knocking or adhesion and strain on the mating surface, it will affect the secondary assembly; will expand due to heat, but cannot be removed
