To study the static contact characteristics of layered hollow cylindrical rollers,an inner ring-roller-outer ring finite element static contact model was established in ABAQUS software,and the effects of inner hollow cylin-drical roller material,hollow rate and radial load on the static contact characteristics of layered hollow cylindrical rollers were compared and analyzed.The results showed that with the decrease of the elasticity modulus of inner hollow cylindrical roller material,the radial contact deformation of layered hollow roller increases,the inner wall stress of outer hollow cylindrical roller increases and the inner wall stress of inner hollow cylindrical roller decrea-ses;with the decrease of hollow rate of layered hollow cylindrical rollers,the radial contact deformation of the roll-ers,and the internal and external hollow cylindrical roller wall stress decrease;with the increase of the external load of the roller,the radial contact deformation of the layered hollow cylindrical roller increases,and the inner wall stress of the inner and outer hollow cylindrical roller increases.
