下列的侧弯和扭曲定义体现为未承载链条的特性。 侧弯——是在一个平直的平

The following definitions of side bends and twists are reflected in the characteristics of unloaded chains. <br>Side bending-is a measure of the lateral bending ability of the chain on a straight plane. This measurement is expressed by the maximum chord height of the arc produced by the lateral bending of the chain, see Figure 1 and Figure 2.

下列的侧弯和扭曲定义体现为未承载链条的特性。<br> 侧弯——是在一个平直的平面上，对链条的侧向弯曲能力的一种测量。这种测量是通过对链条的侧向弯曲所产生圆弧的最大弦高数值来表示，见图1和图2。

The following definitions of side bends and twists reflect the characteristics of the unloaded chain.<br>Side bend - a measure of the lateral bending capacity of a chain in a flat plane. This measurement is represented by the maximum chord height value of the arc generated by the lateral bending of the chain, as shown in Figure 1 and Figure 2.<br>
