我厂在进行设备大修时,将一台LGA80-5000-1型罗茨风机分解,发现风机32316轴承内侧密封套和内圈接触部位,被轴承磨进5～2.5mm,形成一凹形环状,其外侧挡圈的相同部位也被磨进0.2～0.3mm凹痕。经观察其原因是叶轮轴颈部被轴承磨损而变细,导致了轴承沿轴向进行不规则窜动, When I plant equipment overhaul, a LGA80-5000-1 Roots blower decomposition and found that the inner bearing 32316 bearing seal ring and the inner contact parts, the bearings were ground into 5 ~ 2.5mm, forming a concave ring , The same part of the outer ring is also worn into the 0.2 ~ 0.3mm dent. The reason is observed by the impeller shaft bearing wear and thinner, resulting in irregular axial movement of the bearing,
