Design and analysis of magnetic matrix screw based on green manufacturing concept

Lead screws are the most commonly used transmission components in tool machinery and precision machinery, widely various industrial equipment instruments. However, screw tooth profile squeezes friction causes gear to break, surface wear, pitting other damage, which reduces service life of screw; use a large amount lubricants can not ignore environmental impact. The design research this subject based on traditional ball mechanism, magnetic field force, force state transformation be realized without contact. It has significant advantages terms improving product reducing pollution caused by lubricating fluid, is line with trend green sustainable development. This paper analyzes principle non-contact matrix structure principle, conducts finite element analysis parameters thrust torque. Finally, experimental platform designed verify thrust.
