The energy variation of vibration signals is the features of gearbox-case fault diagnosis.
振动信号能量在局域波时频分布中的变化，是局域波法诊断齿轮磨损故障的特征。
2
You can pull the gearbox apart in case of an emergency.
你可以把变速箱拆开，以备急用。
3
The temperature and its field distribution and the heat dissipation through gearboxcase are conditional on each other in computation, thus making the computation much more difficult.
