Abstract: The disclosure relates to a load cell including an elastic element, at least one strain gauge and a limitation element. The elastic element includes a first end portion, a second end portion and a deformation region. The first end portion and the second end portion are arranged along an axial direction and opposed to each other. The deformation region is located between the first end portion and the second end portion. The at least one strain gauge is disposed in the deformation region. When a force is exerted on the first end portion in a first direction, the deformation region is deformed to drive the at least one strain gauge to change shape, so that the force is measured and standardized under a specific range. The limitation element is connected to the elastic element. A gap is formed between the limitation element and the elastic element.

Abstract: 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.

Abstract: 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.
