- W2390125859 abstract "Fracture tooth of gear shaft in well drilling pump was analysed by chemical analysis, mechanical testing metallographic examination macro and microfractography. An investigation was made on trail a pike process of well drilling pump, mating position relation of gear shaft and crankshaft large gear rim, bending fatigue strength of gear in the gear shaft was checked. The results showed that fracture tooth of gear shaft were caused by the local shock bending fatigue which was occurred by the gear shaft and large gear rim gearing malposition, gear bias load in the course of main bearing bolt fracture. Of course, this process was accelerated by large fragility of the material of gear shaft." @default.
