Cold forging of ring gears (under research and development)

A molding method to complete the inner helical gear and outer spur gear in the cold forging process 2.

At Clear Tech, we are currently challenging the cold forging of "ring gears" that are manufactured through cutting processes. The successful prototype of the cold forging method shapes both the inner and outer teeth simultaneously. The direct effects include improved material yield, reduced gear noise, and increased strength, while indirect benefits are expected in terms of environmental impact, miniaturization, and cost reduction. The specific shaping method involves a two-step cold forging process, completing the inner helical gear and outer spur gear. In the first step, the outer and inner teeth are simultaneously formed on a ring-shaped material, and in the second step, a sizing process is planned to achieve the required precision for the gears. [Effects of Development] ■ Improved material yield ■ Reduced gear noise ■ Increased strength ■ Indirectly, effects on the environment, miniaturization, and cost reduction *For more details, please refer to the PDF document or feel free to contact us.
