浅谈动力滚筒的组成和用法
在许多领域或行业中，都会使用到滚筒，而这样的滚筒有动力滚筒，还有无动力滚筒等，不同性能与功能的滚筒，所起到的作用是不同的。例如动力滚筒，它在受力上怎么样？在使用以前，就需要来对它做一个详细的分析。
In many fields or industries, roller will be used, and such roller has power roller and non power roller. Roller with different performance and function plays different roles. For example, what about the power roller? Before using it, we need to make a detailed analysis of it.
本来滚筒就当成是一种由筒体、接盘、轴装配焊接起来的组合构件体，作用上，输送带张力连同扭转力都需要一同转移到轴上的，接着来转变比较复杂的内部应力，作用在滚筒的各个部件上，同时，每个构件上的应力，要在方向与性质上都是不一样的。
Originally, the drum is regarded as a kind of combined component body assembled and welded by the drum, connecting plate and shaft. On the function, the belt tension and torsion force need to be transferred to the shaft together, and then the more complex internal stress will be transformed. On each component of the drum, at the same time, the stress on each component will be different in direction and nature.
就在滚筒输送带两端上的张力大小，那会有巨大的差距，冲遇点的张力超过奔离点的张力。可工作的时候，传动滚筒的表面受压，其径向载荷会从松边到紧边，还需要符合指数规律的。输送带张力、滚筒轴所产生的转角、接盘刚度、简体的厚度等，它们是会决定内部应力的。
There will be a huge gap between the tension at both ends of the roller conveyor belt. The tension at the impact point is greater than that at the departure point. When it can work, the surface of the transmission drum is compressed, and its radial load will be from loose side to tight side, which also needs to conform to the exponential law. The tension of the conveyor belt, the angle of rotation produced by the roller shaft, the rigidity of the connecting plate, the thickness of the simplified body, etc. will determine the internal stress.
也就是说，这筒体上的内部应力，是需要在滚筒围包角在60度的时候，那就是最大的。传动滚筒破损也表现在重载之下，因为轴的弯曲变形，造成接盘和筒壳、轮毂、接盘的焊接地方出现裂纹的。而简单的来增加接盘厚度，进而来增加强度，一般都无法达到你想要达到的目的。反之，还会产生裂纹的，进而来减少接盘的使用寿命。
That is to say, the internal stress on the cylinder is the maximum when the drum shroud angle is 60 degrees. The transmission drum is also damaged under heavy load, because of the bending deformation of the shaft, resulting in cracks in the welding places of the connecting plate, the shell, the hub and the connecting plate. And simply to increase the thickness of the plate, and then to increase the strength, generally can not achieve what you want to achieve. On the contrary, it will also produce cracks, thus reducing the service life of the adapter.
而做出正确的分析，好让自己能轻松的来使用动力滚筒，发挥它真正的作用。
And make the right analysis, so that they can easily use the power roller, play its real role.
