Failure mode analysis of mechanical transmission gears
To improve the reliability of gear transmission,the potential failure modes of gear were analyzed to avoid or reduce the occurrence of gear failure.The main forms of mechanical transmission gear failure was analyzed by using the fault tree analysis method and to establish a gear failure fault tree.The failure reasons of gear were then the fishbone diagram for gear failure analysis was established through discussing from gear design,gear manufacturing,gear material and gear main-tenance,et al.Taking coal mine machinery gears as an example,the failure severity,occurrence probability and detection rate of coal mine drive gear were analyzed using the Failure Mode and Effects Analysis(FMEA)method.A failure mode and impact analysis report for coal mine mechanical gears is established,and a safeguard measures based on the failure mode is proposed,which is helpful to improve the reliability of drive gears in coal mines.
