一般水泥厂的很多重要设备都是采用三角带进行传动的。由于新型干法水泥生产线生产工艺流程的连续性，对机械设备的连续稳定运转也提出了更高的要求，尤其是在熟料的烧成阶段。这些设备的运转状态直接关系到窑的运转率和熟料产量，所以掌握这些设备上三角带的状态非常重要。三角带在运转中如果有太松或打滑等现象，会造成磨损过快，发热甚烧坏，导致使用寿命缩短。但由于这些设备关系到窑的运转，所以不能对这些运转中的设备停下来进行检查。若能及时发现三角带存在的问题，并且提前做好对策和准备，可减少因为三角带原因而引起的不必要的停窑。
Generally, many important equipment in cement plant are driven by triangular belt. Due to the continuity of the production process of the new dry process cement production line, higher requirements are put forward for the continuous and stable operation of mechanical equipment, especially in the sintering stage of clinker. The operation state of these equipment is directly related to the operation rate of kiln and clinker output, so it is very important to master the state of triangular belt on these equipment. If the V-belt is too loose or slippery during operation, it will wear too fast, heat and even burn out, resulting in shortened service life. However, since these equipment are related to the operation of the kiln, these equipment in operation cannot be stopped for inspection. If the problems existing in the triangular belt can be found in time and the countermeasures and preparations can be made in advance, the unnecessary kiln shutdown caused by the triangular belt can be reduced.
三角带的张紧度是必须要经常进行检查以及调整，从而使三角带的张紧力符合要求。
The tension of the V-belt must be checked and adjusted frequently to make the tension of the V-belt meet the requirements.
这是因为如果三角带的张紧力过松会容易出现打滑的现象，也会增加三角带的磨损，甚是不能够传递动力。当过紧的时候则会使三角带出现拉长变形的情况，容易出现损坏和磨损的情况。

This is because if the tension of the V-belt is too loose, it will easily slip, increase the wear of the V-belt, and even fail to transmit power. When it is too tight, the triangular belt will be elongated and deformed, which is prone to damage and wear.
三角带的基准长度是什么？
What is the base length of the triangle?
当三角带绕过三角带轮的时候，三角带带体的长度还有宽度都能够保持不变的层面我们将之称为中性层。
When the V-belt bypasses the V-belt pulley, the length and width of the V-belt body can remain unchanged. We call it the neutral layer.
在规定的张紧力下面，我们沿着三角带的中性层量出来的周长我们可以称之为基准长度，又可以称之为公称长度。
Under the specified tension, the perimeter measured along the neutral layer of the triangular belt can be called the reference length or the nominal length.
基准长度主要是用于三角带的传动中几何尺寸的计算还有三角带的标记，而且这种长度已经标准化了。
The reference length is mainly used for the calculation of geometric dimensions in the transmission of V-belt and the marking of V-belt, and this length has been standardized.
