The Precise Evaluation of the Stiffness of Square Threaded Screws

Abstract:

This paper presents a study on the precise evaluation of the stiffness of square threaded screws which are used in industry. The amount and manner of distribution of stresses that occur in a screw depends on the efforts but also the cross section (shape and size), section where is calculated the stress. The screws are made in many constructive forms and in fuctioning they are calculated at different stresses such as: twisting, bending, shire, buckling or compound stresses to determine the maximum stress of the screw material. These calculations are necessary for establish the functioning conditions for the screws that are used in industry and also for determine the efficiency of the material that are made of. Keywords: square screws, stiffness, circular sectors, cross section
