Manufacturing process can be shortened to 1/4! Iron powder for sintered transmission gears.
Various iron powders for Heganes high-load sintered gears.
High-load sintered gears produced by powder metallurgy can shorten the gear manufacturing process to less than 1/4, providing a new option that not only reduces size and weight but also improves gear characteristics.
The technology of powder metallurgy (PM) is widely adopted in various fields, including the automotive industry, as a sustainable "green" technology with a high material utilization rate (yield) close to 100% and low total energy consumption. By optimizing materials, process conditions, and design, it enables significant reductions in the number of steps previously required for processes such as gear cutting from steel, as well as lightweight and compact gear designs. Additionally, it allows for improvements in gear characteristics such as NVH, along with the addition of desired high functionality. 【Features】 - Elimination of gear cutting and hobbing allows for more than a 25% reduction in process time. - Significant reduction in the number of manufacturing equipment and installation area is possible. - Over 20% weight reduction can be achieved without additional processing steps such as hollowing or thinning. - A 15% reduction in bending and impact stress is possible with shape designs that are difficult with conventional methods. - Shape features such as marking can be added without any additional processes. - Integrated forming of gears and synchro cones can eliminate welding and preliminary processing steps. 【Exhibition Information】 Exhibition Name: 2021 Automotive Technology Exhibition Date: May 24 (Wed) to May 26 (Fri), 2021, 10:00 AM to 6:00 PM (until 5:00 PM on the final day) Venue: Pacifico Yokohama Exhibition Hall (Booth Number: 160)
