摘要
回转窑是建材、冶金、化工等行业生产流程中的核心设备，一次停窑将引起整个生产流程的中断，造成重大经济损失。托轮作为回转窑的支承装置保证其安全、高效、健康地运行很重要。
本文概述了回转窑的应用发展和基本结构。计算了回转窑的各档支撑力并对托轮进行受力分析。针对回转窑轴线调整使用的千斤顶,重点设计了液压回路并且对液压缸进行设计计算。最后对托轮表面维护中采用的动态车削的可行性进行了分析。

Abstract
Rotary kiln is a key equipment in the metallurgy, chemistry and architectural material .Once stop will bring interruption to the whole Production line, and make a great Productivity losses. so safety，efficiency and Healthiness operation is the key Point to advance benefit of the enterprise.
This paper outlines the development ，application and basic structure of the rotary kiln. Rotary kiln's various grade of support strength calculation and the stress analysis to the under roller have been carried out in the paper. The paper also shows a hydraulic circuit design of the jack ,which is in the use of Kiln axis adjustment ,and the calculation to hydraulic cylinders. The feasibility analysis of dynamic turning used in the maintenance of supporting wheel surface is at the end of this paper.
