一般在滚筒的主轴方面
一般在滚筒的主轴方面，按受载情况，可以分为以下两种：
Generally speaking, the main shaft of the drum can be divided into the following two types according to the loading conditions:
1)心轴只承受弯矩，如改向滚筒组的轴；
1) the mandrel only bears bending moment, such as the shaft of the reversing drum group;
2)转轴同时承受弯矩和扭矩，如传动滚筒组的轴；
2) the rotating shaft bears bending moment and torque at the same time, such as the shaft of driving drum group;
轴的材料一般是经过轧制或锻造的碳素钢或合金钢，通常的材质是中碳钢，四十五号钢最为常用的，对于受力较大且尺寸受到限制的轴，以及某些特殊要求的轴可用合金钢，选用材质为四零铬，根据需要，轴一般需经过热处理或表面强化处理，以提高其力学性能和耐磨性等，在一般温度下，合金钢和碳素钢的弹性
The material of shaft is generally rolled or forged carbon steel or alloy steel, and the material is usually medium carbon steel. 45 steel is most commonly used. For shafts with large stress and limited size, as well as some special requirements, alloy steel can be used, and the material is 40 chromium. According to the needs, the shaft generally needs to be heat treated or surface strengthened to improve its mechanical properties and Wear resistance, etc., elasticity of alloy steel and carbon steel at normal temperature

模量相差很小，故采用合金钢不能提高轴的刚度；
The difference of modulus is very small, so alloy steel can not improve the rigidity of shaft;
轴的材质方面一般会经调质处理，对于传动滚筒组，当轴强度指标不满足要求时也可选择合并经调质处理，并按对称循环弯曲许用应力校核；
Generally, the shaft material will be subject to tempering treatment. For the transmission drum group, if the shaft strength index does not meet the requirements, it can also be combined with tempering treatment, and checked according to the allowable stress of symmetric cyclic bending;
筒皮设计技术要求为：
The technical requirements for shell design are as follows:
1)筒皮卷曲时必须顺着钢板的轧制方向；
1) when the shell is curled, it must follow the rolling direction of the steel plate;
2)接头处的错边量不大于1毫米；
2) the unfitness at the joint shall not be greater than 1mm;
3)滚筒包胶后的纵向焊缝必须进行超声波或X射线探伤检查：
3) ultrasonic or X-ray flaw detection must be carried out for the longitudinal weld after the roller is coated with glue:
①超声波探伤进行10%，焊缝达到标准中的二级；
① 10% ultrasonic flaw detection shall be carried out, and the weld shall reach the second level of the standard;
②射线探伤从一端开始探总长度的20%，焊缝达到国标二级，如不合格探伤长度加倍，加倍仍不合格则进行全长探伤，直至符合要求；
② the radiographic inspection starts from one end to detect 20% of the total length, and the weld reaches the second level of the national standard. If the length of the unqualified flaw detection is doubled, the full-length flaw detection shall be carried out until it meets the requirements;
4)筒皮卷好后的圆度公差应不超过0.5；
4) the roundness tolerance after rolling the shell shall not exceed 0.5;
5)材质：Q235型钢，屈服强度为235牛/平米；
5) material: Q235 section steel, yield strength is 235 n / m2;
