Abstract :
To solve the problem that large torque drilling rig requires high performance of the chuck, this paper
introduces the composition and working principle of a normally open hydraulic chuck, as well as the design and
calculation method of its bearing capacity and clamping force. Through the use of creo2.0/simulate finite element analysis module, finite element analysis is made on the main structure parts of the chuck. The results show that the parameter selection and structure design of the chuck mechanism meet the requirements of use, which provides a guarantee for improving the reliability of the chuck mechanism and the overall performance of the drilling rig.
