    • A method and apparatus for automatically monitoring the wear of a chain when in operation in a chain drive assembly. First and second markers are applied to the chain at a predetermined distance apart. A first sensor is disposed adjacent to the chain to coincide with the position of the first marker. A second sensor is disposed adjacent to the chain to coincide with the position of the second marker. The sensors generate signals in response to the detection of the markers. When the chain drive is operated the first and second sensors are initially triggered substantially simultaneously by said first and second markers respectively. After the chain extends through wear elongation is identified by detecting a time delay between the triggering of the first and second sensors by the respective markers. One of the sensors is then moved to a position where substantially simultaneous triggering of the sensors by the markers can be resumed. The distance the sensor has to be moved is measured to determine the elongation length of the chain.
    • 一种用于在链条驱动组件中操作时自动监测链条的磨损的方法和装置。 第一和第二标记以预定距离分开施加到链上。 第一传感器邻近链条设置以与第一标记的位置一致。 第二传感器邻近链条设置以与第二标记的位置一致。 传感器响应于标记的检测而产生信号。 当链条驱动器被操作时,第一和第二传感器最初分别由所述第一和第二标记基本上同时触发。 在链延伸穿过磨损后,通过检测由各个标记触发第一和第二传感器之间的时间延迟来识别。 然后将一个传感器移动到可以恢复通过标记基本上同时触发传感器的位置。 测量传感器必须移动的距离以确定链的伸长长度。
