가스 스프링 Elevation 동작 마찰력 보상 연구 - 가스 씰 조임 기술 연구 및 최적화된 피스톤 구조 개발 A Study on Elevation Motion Friction Compensation in Gas Spring – Study of Gas Seal Lip Technology and Optimized Piston Structure Development
pp.33-39
The study for reducing friction in elevation motion of a large television stand using over 50 inches is performed in this paper. The first study attempted to reduce the frictional force the gas seal lip technology. The second study is for optimized piston structure development by comparison pipe orifice and labyrinth orifice. As the result of the first study, in the gas seal lip technology, the outer-inner diameter of Ø20 × Ø8 in the test result of hollow rod is revealed more proper if the weight of 50 inch television assumed as 30. As the result of the second study, the optimized piston structure development through experiment is fixed orifice specification as labyrinth orifice because pipe orifice is founded slip up/down phenomenon of the Ø0.4~1.0 orifice and the labyrinth orifice is not founded that of the Ø0.4~0.6 orifice both tests on 300 mm intervals.
