| 1. 纸机导辊常见的问题： 1. Common problems of paper guide roller: （1）导辊主轴轴承位磨损和轴承室磨损； (1) lead roller bearing bit wear and bearing room wear; （2）导辊辊面表面划伤； (2) scratch of guide roller surface; （3）导辊辊面腐蚀； (3) lead roller surface corrosion; （4）导辊弯曲变形； (4) bending deformation of the guide roller; 2. 导辊轴承位磨损的主要原因分析 2. Analysis of the main causes of roller bearing bit wear （1）配合尺寸原因，主要是取决于机加工时的误差导致。 (1) due to the error caused by machining process, the size reason is mainly determined. （2）装配原因，取决于装配工艺及技术手段。 (2) assembly reasons, depending on the assembly process and technical means. （3）轴承使用原因，轴承在使用过程温度过高，同时承受轴向力和径向力作用，导致轴与轴承之间过盈尺寸金属疲劳而出现配合间隙，一旦出现配合间隙就使得轴承与轴之间产生相对运动而加剧磨损，严重时使得轴承或者导辊轴报废，造成恶性事件。 (3) bearing using reason, bearing in use process temperature is too high, at the same time bear axial force and radial force, leading to the interference between shaft and bearing the fitting clearance size metal fatigue and appear, once appear, fit clearance makes the intensified with relative movement between shaft and bearing wear, serious when making guide roller bearing or scrap, cause malignant events. |
