磨料磨损、疲劳磨损和胶合等是引起石油钻机传动链条磨损超限，承载；能力降低，最后导致链条断裂破坏的主要原因。

The abrasive wear, fatigue wear and adhesive wear are the main factors causing the excess wear and breaking of the driving chain on drilling RIGS.

链传动钻机采用整体密闭式并车链条箱与变矩器统一驱动形式，在钻机搬家时无需拆装链条，可实现快速安装。

The chain drive RIGS are driven by the integral enclosed compound chain box and torque converter. During rig moves, the chains can be dismantled for ease of installation.
