【摘要】：减速机是机械传动过程中必不可少的部件,在机械传动中具有举足轻重的作用。减速机的设计与优化影响着传动效率的高低。目前,减速机设计基本以传统设计为主,相对独立,与制造、维修等后续阶段脱节。本文以设备全生命周期管理理论为指导,以热试验轧机减速机为设计对象,对减速机进行全面设计,覆盖减速机的结构设计、润滑设计以及维护方案等。首先,本文通过对热试验轧机减速机进行调查和分析,确定其载荷类型。通过对热试验轧机减速机进行传统设计,完成整个减速机的基本设计工作,为三维模拟设计及有限元结构分析奠定基础;其次,以传动轴为减速机主要研究对象,对其进行三维模拟,建立力学分析模型并进行有限元静力学分析,为下一步结构优化提供依据;再次,以轻量化设计为目标,对传动轴进行结构优化设计。根据有限元分析结果及优化流程,对设计不合理的轴进行结构参数优化,使设计更加完善;最后,对减速机的润滑系统进行设计,以及从减速机全生命周期管理理论出发,结合实际使用经验给出了热试验轧机减速机的维护方案和维护方法。
[Abstract]:Reducer is an indispensable part in mechanical transmission, and plays an important role in mechanical transmission. The design and optimization of the reducer affect the transmission efficiency. At present, the reducer design is based on traditional design, relatively independent, disjointed with manufacturing, maintenance and other subsequent stages. Under the guidance of the life-cycle management theory of equipment and the design object of the reducer of hot test mill, the overall design of the reducer is carried out, covering the structural design, lubrication design and maintenance scheme of the reducer. Firstly, the load type of reducer of hot test mill is determined by investigation and analysis. Through the traditional design of the reducer of the hot test mill, the basic design work of the whole reducer is completed, which lays the foundation for the 3D simulation design and the finite element structural analysis. Secondly, the transmission shaft is taken as the main research object of the reducer. The three-dimensional simulation, the establishment of mechanical analysis model and finite element statics analysis for the next step to provide the basis for structural optimization; thirdly, the light weight design as the goal, the transmission shaft structure optimization design. According to the results of finite element analysis and optimization flow, the structural parameters of the shaft with unreasonable design are optimized to make the design more perfect. Finally, the lubrication system of the reducer is designed, and the whole life cycle management theory of the reducer is introduced. Combined with practical application experience, the maintenance scheme and maintenance method of hot test mill reducer are given.
