三峡升船机锁定机构单点保压失效时小齿轮受力变化

通过对三峡升船机船厢水深与锁定机构设定特定的研究条件，分析锁定机构单个驱动点保压失效状态下小齿轮受力变化和船厢水深对锁定机构受力的影响，通过研究不同条件下小齿轮的受力特点、动作规律，使用数学方程核算船厢倾斜状态对锁定机构受力的影响，从理论上得出此研究条件下小齿轮受力的定性和定量变化规律。结果表明，锁定机构的保压性能失效会引起船厢驱动机构的受力变化；船厢倾斜对锁定机构动作的允许偏载水深是有影响的，但此影响较小。

Force change on pinion gear in locking mechanism of Three Gorges ship lift under single-point pressure maintenance failure

Based on specific research condition for the water depth and locking mechanism of the Three Gorges ship lift chamber,we analyze the force variation of pinion gear and the influence of the water depth of the chamber on the force of the locking mechanism under the condition of single driving point pressure holding failure of the locking mechanism,and study the force characteristic and action rule under different conditions,check the influence of ship lift chamber inclination on the force on locking mechanism by mathematical equation,and obtain the qualitative and quantitative variation rule of the force on the pinion gear under this research condition theoretically.The results show that the pressure maintenance failure of locking mechanism can cause the force change of the driving mechanism for chamber.The influence of ship chamber inclination on the allowable unbalance loading water depth of locking mechanism is small.
