星型无油空压机轴承寿命的估算

摘要

全无油空压机的可靠性直接关系到用户的利益.当前随着社会经济的发展,全无油空压机使用范围越来越广泛.对机器的运动机构中轴承选型的依据,有关书籍中理论知识较多,而接触实际的典型例题较少.从我厂开发的系列星型空压机中的四星型XW-3/10-QX机器为蓝本,系统地阐述该机的10只轴承的寿命估计,计算中使用的先行数据参见该机的热力计算书、动力计算书,有关的计算结果以雷达图形式给出.得出的结果形象、直观,可在该机轴承寿命之间相互比较,也可类推到同类机型中作一比较.%The reliability of oil-free air compressor is directly related to the interests of users.With the current socio-economic development, the range of oil-free air compressor is more widely used.There is more theoretical knowledge about the foundation of bearing selection in the movement body of machines,but less contact with the real typical examples.Set the four-star XW-3/10-QX machine as an example, which belongs to series star-type air compressor developed by our plant, this paper has systematically specified the using-life estimation of the 10bearings on this machine.The first data used in the computation references the thennodynamic calculation books and the power calculation books.The relative calculation results are given in the form of radar chan.The obtained results are image and intuitive,which can be compared between the bearings ' life of this machine, and can also analogize to the same type machine in comparison.
