气动摩擦离合器是钻机上一种很重要的、且或是最易损坏的部件,在钻机的整个传动装置中,它是唯一的单纯靠摩擦力传递负荷的元件。其它的元件,例如钢丝绳、链条和牙嵌离合器等,都是依靠某种材料承受弯曲、剪切、压缩或拉伸等负荷的,然而摩擦离合器则只凭一个光滑的工作面和一种摩擦材料之间的摩擦力来传递负荷。摩擦力的大小由外加的措施进行控制(对于气动摩擦离合器,由压缩空气来控制)。
Pneumatic friction clutches are a very important and often the most damaging component of rigs and are the only elements that simply transmit loads by friction throughout the drive. Other components, such as wire ropes, chains and jaw clutches, rely on a material that bears bending, shearing, compressing, or stretching loads. However, friction clutches rely on a smooth work surface and a friction material The friction between the load to pass. The amount of friction is controlled by additional measures (for compressed air control for pneumatic friction clutches).
