Analysis of Axial Contact Deformation Factors of Drafting Roller Connecting and Tightening Surface
In order to ensure the installation quality of drafting roller,the axial contact deforma-tion of the connecting and tightening surface between the drafting roller and the inner ring of the roller bearing is taken as the starting point,and the change of internal stress of the reverse carding material,the surface roughness of the contact surface,the flatness error and the contact state after loading and tightening are analyzed.The improvement measures are put forward from optimization design,material selection,process reference selection,internal stress relief,machining allowance determination and flatness error reduction.It is pointed out that in the as-sembly and assembly,it is necessary to pay attention to the contact accuracy of the associated parts to ensure the installation quality of the drafting roller,strictly control the technical stand-ards,and strengthen cleaning and maintenance to ensure the spinning needs of high stability and high reliability.
