Research on Static Stiffness of Roller Guideway

Directing an important kind of joints of the machine tool—linear roller guideway,the static stiffness calculation method of it was presented.The deformation equations of roller guideway with vertical force,horizontal force and moment loads were deduced.The relationship between loads and deformation was built by applying the Hertz contact theory.A certain guideway was studied by using this method.The conclusion has been obtained by an example and the calculation results.
