"our goal is to become the preferred brand for domestic substitution in the precision linear transmission market!" on the morning of september 20, the 2024 world industrial design conference opened at the yantai bajiaowan international convention and exhibition center. the planetary roller screw developed by yantai aidi precision machinery co., ltd. won the gold medal in the yantai "mayor cup" industrial design competition. as a nationally renowned manufacturer of precision machinery and equipment, aidi precision regards domestic substitution as the company's development mission.
"in the field of precision machinery manufacturing, many core technologies and components are in the hands of foreigners. we hope to accelerate the pace of domestic substitution through technological innovation." song yulin, product manager of eddie precision transmission project, told reporters that the lead screw is the core component of mechanical transmission and the heart of mechanical transmission, while the planetary roller screw has better stability, load-bearing capacity and durability, and is a high-quality product for domestic substitution.
song yulin introduced that this planetary roller screw adopts a special 90° thread angle, with a smaller radial dimension, so the axial load is greater. in addition, the thread profile of the planetary roller screw innovatively adopts a slightly convex arc profile, which reduces the friction resistance of the nut, screw, and ball meshing, so the product has stronger adaptability and better overload capacity.
"relying on eddie precision's strong equipment foundation, our key parts nuts, screws, and roller materials are all professionally customized, and the special heat treatment process makes the working surface harder and more tough, less prone to creep, and has a longer service life." song yulin said that currently planetary roller screws can be widely used in medical equipment, robot joint transmission systems, aviation, aerospace and other systems, and the product performance has been further verified.
it is understood that the transmission project of yantai eddie precision machinery co., ltd. currently has a research and development team of more than 50 people. on the basis of fully absorbing public technologies and experiences from europe, japan and other countries, after years of technical accumulation, independent research and development has made breakthroughs in many key technologies such as screw raceway structure and steel ball contact angle design, screw thermal deformation compensation, screw and guide rail preload setting, screw and guide rail return ball inverter system, etc., which greatly improved the product performance of domestic roller screws and contributed to the localization substitution of related products.
