Abstract:In order to ensure the installation quality of drafting roller，the axial contact deformation 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 assembly 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 standards，and strengthen cleaning and maintenance to ensure the spinning needs of high stability and high reliability.
Key Words:roller；guide rod shoulder surface；pilot hole end face；bearing；internal stress； contact deformation；flatness error；surface roughness
