The variation tendency of the film thickness is similar to that of the screw speed, while the evolution of the friction torque at ball-screw interface is dependent on the ball spin speed. Compared to the ball-nut interface, the friction coefficient is higher on the ball-screw interface. ...
The dual-drive ball screw pair serves as a crucial element within the fixed gantry machine tool with cross-rail movement. When in service, the dual-drive ball screw pair experiences variations in axial load, impacting the contact load distribution of the ball screw pair. A calculation model for...
The stiffness of the individual kinematic joints (screw nut joints and bearing joints) of the feed system and the tension/compression and torque stiffnesses of the screw shaft on both sides of the nuts are the most significant factors affecting the dynamics of the system. Therefore, the ...
The ball screw is widely used in theX,Y, andZaxes of high-speed and high-precision machine tools; its importance is self-evident. Its dynamic characteristics directly affect the fatigue life of the mechanism, the bandwidth of the servo system [1,2,3], the positioning accuracy of the machin...
