回转窑剖分式滚圈结构设计与接触应力分析

Structural design and contact stress analysis of rotary kiln for split ring rolling

针对目前回转窑整体式滚圈在铸造、运输、安装及拆卸等过程中存在的难度,提出设计剖分式滚圈的设想,以解决整体式滚圈存在的问题。在剖分式滚圈的基本结构尺寸与整体式滚圈尺寸相同的情况下,校核其滚圈的刚度、强度。通过分析滚圈受力以及破坏失效原因可知,接触应力是引起滚圈破坏的主要因素。运用ANSYS软件分析了滚圈分体相对于托轮位于不同位置时的受力情况,并以此来校核其设计是否合理。

In order to solve the problems of rotary kiln in the overall rolling ring such as casting, transportation, installation and demolishment. Try to design rolling ring in split form. Check the stiffness and strength of rolling ring in split form as basic structure size under the same circumstances. Contact stress is the main factors causing rolling ring damaged by analysing the contact stress and reasons for inefficacy. Apply ANSYS software to analyse the stress between the split and rolling ring-child care at different locations, and analyse the reasonable of the design.
