Helical gears manufactured using a new method of vibration press

Amada Holdings (HD) has developed a method to reduce the machining time of gears used in transmissions with Subaru by 75% and the total cost by 30% compared to the conventional method. The new method replaces machining with presses instead of machine tools. A servo press machine with a high degree of freedom in control presses the material intermittently as if it were vibrating. The company devised a method of pressurizing the material and filling the dies with oil. The company aims to put this new method to practical use as soon as possible, as it enables mass production of high-precision gears at low cost. This is a new method of fluid pulse forging for helical gears (helical gears) with diagonal tooth threads, and is the result of Amada Orii (Isehara City, Kanagawa Prefecture), an affiliate of Amada HD, and Subaru. A related patent has been jointly applied for. (Photo taken on June 7, 2019, location unknown, credit: Nikkan Kogyo Shimbun / Kyodo News Images)
