Provided is a chain elongation detection device that can easily confirm the amount of elongation and the position of elongation with respect to local elongation of a chain. A chain local elongation detection device is provided with: an engagement height measurement device that measures the engagement height of a chain within the range in which a drive sprocket or a driven sprocket engages with the chain; and a signal processing device that obtains the difference in height between adjacent rollers in the chain using the signal acquired by the engagement height measuring device, and estimates the local elongation of the chain from the obtained difference in height. The position at which local elongation of the chain occurs is determined on the basis of a waveform superimposed on a signal acquired by the engagement height measurement device due to the shape provided in the chain.
提供链伸长检测装置,其对于链的局部伸长能够容易地确认伸长量以及伸长的位置。链局部伸长检测装置具备:啮合高度测定装置,其测定驱动链轮或从动链轮与链啮合的范围内的链的啮合高度;以及信号处理装置,其使用由啮合高度测定装置取得的信号,求出链中的相邻的辊的高度之差,根据所求出的所述高度之差来估计所述链的局部伸长,根据由于设置于链的形状而在由啮合高度测定装置取得的信号中叠加的波形来确定产生链的局部伸长的位置。
