핀기어 적용 롤러 스크류의 기어설계에 관한 연구

Abstract

Linear actuators, including hydraulic, pneumatic, and electric cylinders, are essential for linear motion in variousapplications. Hydraulic cylinders are commonly used in high-load environments. However, recent environmentalregulations targeting carbon emissions are driving interest in electric actuators. Among these, electromechanicalactuators are particularly beneficial owing to their energy efficiency, eco-friendliness, precise positioning, andcompact design. However, the key component, the roller screw, remains costly, and relies heavily on importsowing to manufacturing challenges. This study presents a new roller screw design that replaces the traditionalspur gear with a pin gear with the aim of reducing production costs and dependency on imports. A prototypecreated via 3D printing successfully demonstrates operational viability, indicating the feasibility of domesticproduction for mass manufacturing. This approach supports the sustainable development of high-performanceactuator technologies.
