The preloaded double-nut ball screw (DNBS) is widely used in precision transmission for its
high load capacity and contact stiffness. However, few researches have been done on the …

Currently, due to the rare consideration on the coupling of the various rolling joints and their
directional dynamic parameters, and the constraints of the traditional modeling methods, the …

A comprehensive static load distribution model of double nut ball screw (DNBS) is
presented. The axial, lateral, and torsional deformation of the screw and the geometric error …

The contact properties of the screw-nut pair play a decisive role in the wear rate and service
life of ball screws. The difficulty of the ball contact loads directly detected has resulted in the …

Mechanical transmissions are addressed with a system-level view for preliminary sizing and
virtual prototyping. The simulation needs are transformed into requirements that drive the …

The macroscopic relative motion solid-liquid interface widely exists in the contact motion
pairs of machine tools and other mechanical equipment. In order to accurately obtain the …

Ball screw drives are commonly used to provide linear motion in machine tools. And stiffness
