自由落钩卷扬机机构设计 摘要 本设计主要介绍了液压卷扬机的结构、总体设计及工作情况。其中对液压卷扬机传动系统的设计做了分析和理论推导,为开发同类产品提供了设计方法。卷扬机是钻探施工中升降钻具、套管及处理孔内事故的主要设备之一。液压卷扬机结构紧凑,传动平稳,调整范围大,操纵简单,易于安装。它即可与钻机配套,又可独立使用,是一个很值得开发的产品。 随着我国各项事业的迅猛发展,对相关设备的安全性、方便灵活性和工作效率提出了更高的要求。为满足现在施工升降机的需要及冶金、矿山、轻工等行业起重设备更新之需,设计制造自由落钩卷扬机是事在必行的。本卷扬机采用三级行星齿轮传动，行星齿轮传动体积小，能够满足卷扬机的结构要求，同时行星齿轮传动效率高，承载能力大，工作平稳，用三级行星齿轮传动增大了转动比，从而达到了设计要求。 关键词：自由落钩卷扬机；卷筒；传动比；行星齿轮；效率 Abstract The paper i
