| Abstract: | The friclional factor between chuek jaw and drilling rod is important in calculaling the chuck working capacity.This thesis introduced a study method for frietional factor, based on experimental study. It obtained the variable range of the frictional factor and a principle about how to adopt the frictional factor, which cleared the elements that lake effect on the frictional factor.The solution of the experimental study can be used in the chuck design directly. |
