船用克令吊塔身大底板回转支承安装面平面度处理方法的理论研究和应用

Theoretical Research and Application of Flatness Treatment Method for the Slewing Bearing Installation Surface of the Large Bottom Plate of the Ship Crane Tower

摘要: 船用克令吊塔身大底板在与塔身壳体焊接后其会发生变形，进而导致大底板上回转支承安装面也会跟着变形。当回转支承安装面的平面度检测结果超出技术要求时，通常采用对安装支承安装面再次机加工的方法保证该面的平面度，以满足回转支承的安装要求。而本文介绍的是采用垫垫片的工艺方法保证塔身大底板上回转支承安装面的平面度满足技术要求。在塔身大底板上回转支承安装面的待调整位置与回转支承之间增加垫片，以调整塔身大底板的上回转支承安装面平面度，解决了塔身大底板因焊接变形导致回转支承安装面平面度超差的问题，降低了生产成本、缩短了产品的生产周期、提高了生产效率。

Abstract: The housing base of Deck Crane house will be deformed after welding with the house structure, which will lead to the deformation of the housing base surface of the slewing ring support on housing base. When the test result of the flatness of the housing base surface of the slewing ring support exceeds the technical requirements, the method of machining the housing base surface is usually used to ensure the flatness of the surface to meet the installation requirements of the slewing ring. This paper introduces the technology method of shim to ensure that the flatness of the housing base surface of the slewing ring on the housing base of the housing meets the technical requirements. A shim is added between the position to be adjusted on the house base surface of the slewing ring and the slewing ring on the house base of the housing structure to adjust the planarity of the house base surface of the upper slewing support on the house base of the housing structure to solve the problem that the planarity of the house base surface of the slewing ring is excessive due to welding deformation of the house base of the housing structure, reducing the production cost, shortening the production cycle of the product and improving the production efficiency.
