三、轴承与最适当的润滑油清洁度 FAG公司发表了有关轴承寿命与润滑油清洁度关系的轴承目录和技术资料,其中有关机器与润滑油清洁度关系的资料,如表3所示。污染系数如表4所示。 表4中的β值是评价滤油器在平均时间内捕捉污染颗粒的能力。β值越大,捕捉能力越大。如β_3≥200表示捕捉>3μm颗粒的能力,即在进入滤油器前的油 Third, the bearing and the most appropriate cleanliness of the oil FAG company published a bearing on the bearing life and lubricant cleanliness of the bearing directory and technical information, including the relationship between machine and lubricant cleanliness data, as shown in Table 3. The pollution coefficient is shown in Table 4. The β value in Table 4 is an assessment of the ability of the oil filter to capture contaminant particles over a mean time. The larger the value of β, the greater the ability to capture. If β_3 ≧ 200 means the ability to capture particles> 3 μm, ie the oil before entering the oil filter
