In this thesis, we aim at the rotary motor and safety valve of 20t excavator as the research object and mainly achieve the study as follow:(1) The design of the core parts of rotary motor used for 20t excavator is performed according to the axial piston motor design principle.
本文以20t挖掘机回转马达和安全阀为研究对象,主要完成以下几方面的内容:(1)依据斜盘式轴向柱塞马达的设计原理,设计了20t挖掘机回转马达的芯部零件。
At present, the technology of rotary motor for excavator aboard is very mature, while in domestic is still in the developing stage and mostly depend on the import, so it\'s urgent to research on them.
