Abstract:

On the basis of analyzing the structure of screw drive chuck，a brief design calculation is made on the technical parameters of screw and nut. According to the application problems of chuck on large diameter drill, its structure is improved and perfected. With the reliable clamping, this type of chuck can meet the requirements of drilling rig and better technical and econom57ic results are achieved.
