介绍了高压煤油恒速液动机(简称"液动机")的转子倾覆现象,分析了机理,并按照发生的原因将倾覆现象分为主动倾覆和被动倾覆.重点研究了主动倾覆,基于对转子柱塞组件的受力分析,提出了倾覆条件的数学表达,引入了无量纲的倾覆安全系数,以定量表达倾覆风险.分析了被动倾覆的原因,并提出了解决被动倾覆的方法.在产品设计中应避免出现主动倾覆和被动倾覆.
The tilting of the rotor of constant speed hydraulic motor driven by high pressure kerosene(hydraulic motor for short)is introduced,and the tilting mechanisms are analyzed.According to the causes,the tilting phenomenon is grouped into initiative tilting and passive tilting.The research on initiative capsizing is carried out emphatically,the mathematical expression is derived based on the mechanics analyzing of the rotor and pistons,and the dimensionless tilting safety factor is introduced to quantify the tilting risk.The causes of passive capsizing are analyzed,and the corresponding solutions are proposed.The initiative tilting and passive tilting should be avoided during the product designing process.
