卡盘是岩心钻机中的一个重要部件,它担负着把扭矩和轴向力传递给钻具的任务。对于卡盘性能的要求,在很多著作中已有详述,一般专业人员也均了解。但对于卡盘的结构设计和能力计算,则还有很多问题值得商榷和探讨。本文即想在这方面谈些看法。 本文只涉及卡光钻杆的卡盘,着重分析用得最广的靠卡套斜面来增力的液压卡盘。 Chucking is an important part of a core rig that carries the task of transmitting torque and axial forces to the drill. The requirements for chuck performance have been described in many books and are generally understood by the average professional. However, there are still many problems worth discussing and discussing about the structural design and capability calculation of chuck. This article would like to make some comments in this regard. This article only relates to the card chuck chuck, focusing on the most widely used by the ramp to increase the hydraulic chuck chuck.
