新型液压冲击器回油储油腔的设计理论研究

Research on design theory on the return oil chamber of a new hydraulic impactor

在分析国内外液压凿岩机和液压碎石机结构的基础上 ,提出了一种新型设有储油腔的液压冲击器 ,有效地解决了活塞冲程回油背压高、活塞运动阻力增大的问题 ,并研究了这种储油腔的设计计算方法 ,为今后进一步改进现有液压冲击器提供参考。

In this dissertation the analysis of the hydraulic rock breaker and rock drill at home and abroad leads to an return oil chamber of a new hydraulic impactor.So it solves the problem of locomotion hamper accretion at piston reversion and piston stroke.The design method of this return oil chamber is studied,and it is a valuable reference for the improvement of hydraulic impactor.
