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