不管采用何种工艺方式，对辊筒的结构、设计、材料选择和加工制造应符合下面几个基本要求： Regardless of the process, the structure, design, material selection and manufacturing of the roller should meet the following basic requirements: 1．辊筒应具有足够的刚性，确保在重载作用下，弯曲变形不超过许用值。 1. The rollers should be rigid enough to ensure that bending deformation does not exceed allowable values under heavy loading. 2．辊筒表面应有足够的硬度，一般要求达到HRC50度以上，具有较强的耐腐蚀能力。 2. The surface of the roller shall have sufficient hardness, which is generally required to meet the HRC50 degree, and has a strong corrosion resistance. 3．辊筒工作表面应精细加工，以保证尺寸精度和表面粗糙度。 3. The working surface of the roller shall be carefully machined to ensure dimensional accuracy and surface roughness. 4．辊筒的材料应具有良好的导热性， 4. The material of the roller should have good thermal conductivity, 辊筒按用途分驱动辊和从动辊。按驱动方式分为动力滚筒和无动力滚筒。 Rollers are driven by use and driven roller. The driving mode is divided into power roller and powerless drum. 无动力输送辊筒也叫自由辊筒，是由筒体、轴芯、深沟球轴承和轴承安装架组成，使用中为辅助滚动使用，自身没有动力，靠外力滚动。 The free roller is also called free roller. It is composed of tube body, shaft core, deep groove ball bearing and bearing mounting bracket. In use, it is used as auxiliary rolling, and has no power and can be rolled by force. 有驱动辊筒一般指内置电机电动滚筒，在这里我们还指带有链轮、同步带轮等可以通过减速电机驱动的辊筒。构成结构与无动力基本相同，只是内置了电机或者外面加装了链轮或同步带轮等其他可以通过减速电机驱动的部件。 The driving roller generally refers to the electric roller of the internal motor. In this case, we also refer to the roller which can be driven by the reduction motor with the chain wheel and the synchronous belt wheel. The structure is basically the same as the lack of power, except that the motors are built in, or other parts that can be driven by the deceleration motor, such as a sprocket or a synchronous belt wheel.
