【摘要】：作为煤矿刮板输送机最重要的传动部件之一,行星减速器的质量备受关注,而近年来,减速器输出端浮动油封的漏油现象频繁发生,已经严重制约了刮板输送机成套设备整体质量的提高。如果在初期使用中发生泄漏而不加以重视,随着漏油状况的发展会因为严重缺油引起齿轮、轴承等关键零件的损坏失效,进一步造成减速器总成的报废。本文旨在针对刮板输送机传动部减速器长期发生渗漏油的问题,对其展开分析研究。刮板输送机减速器涉及到的密封型式多种多样,本论文着重将研究对象制定在输出端浮动油封,采用浮动油封密封机理与泄漏原因分析相结合的研究方法,找出组装工艺、检查等方面存在的不足,提出相应的技术改进措施。参照4290型浮动油封和密封腔结构特征,建立密封零件截面的二维模型,通过对其进行物理运动和受力分析实现理论计算,得到合理的组装轴向调整间隙值。为了更加真实的反映实际工况和技术条件,开展了大量的模拟实验,将所得实验数据与理论数据做对比分析。同时,制作了运转实验装置做跟踪记录,验证分析结果,最终得出两个密封零件之间最佳的组装间隙值。将4290型浮动油封取得的研究方法扩展到其余型号的浮动油封,应用于工艺生产,为实际生产提供依据。最终有效解决了浮动油封早期失效的问题,大大提高了浮动油封的使用寿命,避免由于渗漏油引起的一系列减速器质量问题。该方法具有广泛的应用价值,对其它使用浮动油封的企业具有重要的参考作用。
[Abstract]:As one of the most important transmission parts of the scraper conveyor in coal mine, the quality of planetary reducer has attracted much attention. In recent years, the oil leakage of floating oil seal at the output end of reducer occurs frequently. Has seriously restricted the scraper conveyor complete sets of equipment overall quality improvement. If leakage occurs in the initial use and is ignored, with the development of oil leakage, the failure of the gear, bearing and other key parts will be caused by the development of oil leakage, which will further lead to the scrapping of the reducer assembly. The purpose of this paper is to analyze and study the long-term leakage of oil in the transmission reducer of scraper conveyor. There are a variety of sealing types involved in the reducer of scraper conveyer. In this paper, the object of study is made in the floating oil seal at the output end, and the research method combining the sealing mechanism of the floating oil seal with the cause analysis of leakage is adopted to find out the assembly technology. Inspection and other aspects of the shortcomings, put forward the corresponding technical improvement measures. According to the structural characteristics of the 4290 type floating oil seal and the seal cavity, a two-dimensional model of the section of the sealing part is established. The theoretical calculation is realized through the physical movement and force analysis, and the reasonable axial adjustment clearance value is obtained. In order to reflect the actual working conditions and technical conditions more truthfully, a large number of simulation experiments were carried out, and the experimental data were compared with the theoretical data. At the same time, the tracking record of the operation experimental device is made to verify the analysis results, and finally the best assembly clearance between the two sealing parts is obtained. The research method of 4290 type floating oil seal is extended to other types of floating oil seal, which is applied to process production and provides the basis for actual production. Finally, the problem of early failure of floating oil seal is solved effectively, the service life of floating oil seal is greatly improved, and a series of reducer quality problems caused by oil leakage are avoided. This method has wide application value and has important reference function to other enterprises that use floating oil seal.
