Analyses of contact forces and kinetic motion on heavy load ball-screw

Analyses of contact forces and kinetic motion on heavy load ball-screw

Effects of contact angle and groove factor of a heavy load ball-screw are discussed with the variation of contact forces at eight ball circulations. Contact forces are varying as a sinusoidal function of each circulation owing to the variation of phase angle. With the increase of contact angles, con...
