About this document
Ball Screw Service Life Calculation by Abel ferreira de brito is a document available to read on EtoBox.
1) The service life of a ball screw is the period of time from initial use to becoming unusable, which is generally divided into fatigue life when delamination occurs and accuracy deterioration life due to wear. 2) The basic static load rating is the axial load that causes 0.01% permanent deformation, while the basic dynamic load rating allows 90% of identical screws to rotate 106 revolutions without flaking under the same conditions. 3) Fatigue life is calculated based on average load, load coefficient
