【摘要】：高温润滑脂是高温设备正常运转的关键,其性能的好坏直接关系到高温设备的运行状态。高温润滑脂轴承寿命是高温润滑脂的一项极其重要性能指标,它是高温润滑脂综合性能的反映。我国润滑脂行业缺乏对高温润滑脂轴承寿命试验技术的研究,同时也没有成熟的自主开发的试验设备。所以高温润滑脂轴承寿命试验技术的研究具有重要的现实意义。本文具体工作内容如下： (1)分析了国内外高温润滑脂轴承寿命试验技术的研究现状以及存在的问题,给出本论文主要研究内容。 (2)通过分析高温润滑脂在滚动轴承中的失效机理和现有的润滑脂轴承寿命试验方法,提出一种更为适合高温润滑脂轴承寿命试验的方法。 (3)分析了高温润滑脂轴承寿命试验系统的功能要求,完成了试验系统的总体设计。 (4)对高温润滑脂轴承寿命试验台设计中的关键技术开展研究：加载装置方案及加载力的控制、主轴临界转速的分析计算、辅助轴承润滑系统设计。 (5)对测控系统结构进行了分析,以图形化编程语言LabVIEW为平台,应用OPC技术实现了基于LabVIEW DSC模块的PC与PLC之间的实时通讯,设计了系统软件的主要工作模块,并对其进行了相关调试工作。
[Abstract]:High temperature grease is the key to the normal operation of high temperature equipment, and its performance is directly related to the running state of high temperature equipment. High temperature grease bearing life is an extremely important performance index of high temperature grease, it is the reflection of the comprehensive performance of high temperature grease. The life test technology of high temperature lubricating grease bearing in our country is lack of research, and there is no mature self-developed test equipment at the same time. Therefore, the study of high temperature grease bearing life test technology has important practical significance. The main contents of this paper are as follows: (1) the research status and existing problems of life test technology of high temperature lubricating grease bearing at home and abroad are analyzed. The main contents of this paper are given. (2) by analyzing the failure mechanism of high temperature grease in rolling bearing and the existing life test method of lubricating grease bearing, A more suitable method for life test of high temperature lubricating grease bearing is put forward. (3) the functional requirements of high temperature lubricating grease bearing life test system are analyzed. The overall design of the test system has been completed. (4) the key technologies in the design of high temperature lubricating grease bearing life test bench are studied: the loading device scheme and the control of loading force, the analysis and calculation of the critical speed of spindle, Design of auxiliary bearing lubrication system. (5) the structure of measurement and control system is analyzed. The real-time communication between PC and PLC based on LabVIEW DSC module is realized by using OPC technology on the platform of graphic programming language LabVIEW. The main working modules of the system software are designed and debugged.
