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: An actuator is provided, including a fixed assembly and a movable assembly. The fixed assembly includes a coil module, a base, a first screwing member, and a linear rail. The first screwing member passes through the base and the linear rail, and the linear rail is positioned on the base. The movable assembly includes a U-shaped back board having an inner space, a first magnetic module, a second magnetic module aligned with the first magnetic module, and a sliding block. The first and second magnetic modules are disposed on the U-shaped back board and accommodated in the inner space. The coil module is disposed between the first magnetic module and the second magnetic module. The sliding block is positioned on the U-shaped back board in the inner space, and slidably connected to the linear rail.

Abstract: A speed reducing device includes a motor and a speed reducing mechanism. The motor includes a stator portion and a rotor portion. The rotor portion includes a first eccentric ring and a second eccentric ring. The speed reducing mechanism is partially accommodated within the rotor portion. The speed reducing mechanism includes a first roller assembly, a second roller assembly, a third roller assembly, a first cycloid disc set and a second cycloid disc set. The first roller assembly includes at least one first roller. The second roller assembly includes at least one second roller. The third roller assembly includes an output shaft and at least one third roller. The first cycloid disc set is mounted around the output shaft and disposed within the first eccentric ring. The second cycloid disc set is mounted around the output shaft and disposed within the second eccentric ring.

Abstract: A motor driven linear actuator comprises an electric motor, a ballscrew device, and a rolling bearing. The electric motor includes a motor shaft having a first end portion. The first end portion includes an end surface and a receptacle having a first accommodation space. The ballscrew device includes a screw having a first end portion coaxially connected to the first end portion of the motor shaft. The first end portion of the screw includes a first section to be accommodated in the first accommodation space for fixing the screw with the motor shaft. The rolling bearing is disposed between the electric motor and the ballscrew device for supporting the first end portion of the screw. The end surface of the motor shaft contacts and abuts against the rolling bearing for limiting the movement of the rolling bearing between the electric motor and the ballscrew device.
