气动摩擦离合器(简称气离合器)是石油钻机上广泛应用的一种重要传动元件。目前,在我国,由于气离合器的损坏比较严重,大大影响了钻井时效和钻机的工作能力,成为钻机中的主要薄弱环节之一,随着钻井速度的提高和钻井深度的增加,这个问题变得更加突出。为更好地适应我国石油工业大跃进的形势,钻机气离合器的革新也就成为当前旧钻机改造和新钻机设 Pneumatic friction clutch (referred to as gas clutch) is widely used on the oil rig an important transmission components. At present, due to the serious damage of the gas clutch in China, it greatly affects the drilling aging and the working ability of the drilling rig and becomes one of the main weaknesses in the drilling rig. As the drilling speed increases and the drilling depth increases, the problem becomes More prominent. In order to better adapt to the situation of the Great Leap Forward in China’s petroleum industry, the innovation of the gas clutch for drilling rigs will become the current reform of the old drilling rigs and the construction of new drilling rigs
