Publication number: 20210238715Abstract: The present disclosure provides an aluminum alloy composition and a manufacturing method thereof. By utilizing the mutually insoluble properties between tantalum and silver and sequentially adding chromium, tantalum and silver to an aluminum master alloy containing copper in plural times of melting, it avoids the eutectic reaction between chromium and silver, and required eutectic compositions are formed. Thus, the aluminum alloy composition with excellent corrosion resistance, fatigue resistance, wear resistance and high-temperature resistance is obtained. The aluminum alloy composition comprises 4.2 to 5.5 weight percent copper, 1.4 to 2.0 weight percent magnesium, 0.5 to 1.2 weight percent manganese, 0.05 to 1.0 weight percent silicon, 0.05 to 0.8 weight percent chromium, 0.01 to 0.5 weight percent tantalum, 0.01 to 0.5 weight percent silver and the balance of aluminum.Type: ApplicationFiled: June 30, 2020Publication date: August 5, 2021Inventors: Fei-Yi Hung, Yu-Xian Huang, En-Yi Chu

Patent number: 10520062Abstract: A cycloid speed reducer includes two rotating disc assemblies. Each rotating disc assembly includes two cycloid discs. In other words, the cycloid speed reducer has four cycloid discs to be contacted with the corresponding rollers. Consequently, the load withstood by each cycloid disc is reduced. Since the cycloid speed reducer has stronger structural strength, the cycloid speed reducer can be applied to the high-load circumstance. Moreover, an eccentric assembly of the eccentric device includes plural eccentric cylinders. The eccentric cylinders are installed within the axle holes of the corresponding cycloid discs. Due to the plural eccentric cylinders, the eccentric direction of two cycloid discs is opposite to the eccentric direction of the other two cycloid discs. Consequently, it is not necessary to install an additional weight compensation device in the cycloid speed reducer to compensate the dynamic equilibrium.Type: GrantFiled: April 27, 2018Date of Patent: December 31, 2019Assignee: DELTA ELECTRONICS, INC.Inventors: Ching-Hsiung Tsai, Jia-Ming Wu, Yu-Xian Huang
