| Abstract(J) | 駆動系歯車は熱処理により強度と耐摩耗性を得るが，熱処理歪みによる変形を矯正する必要がある．特に中空構造の遊星歯車用インターナルギヤは変形が著しい．そこで，高強度と低歪みを両立する材料および工法の組み合わせを開発した．本手法により，矯正工程を省略しつつ高精度な歯車の製造が可能となる． Translation |
| Abstract(E) | Drivetrain gears acquire high strength and wear resistance through heat treatment, but the resulting thermal distortion necessitates a subsequent deformation correction step. Hollow-structured internal gears for planetary gear systems are particularly susceptible to severe deformation. To address this challenge, we have developed a novel combination of materials and processing methods that achieves both high strength and low distortion. This approach enables the production of high-precision gears while entirely eliminating the correction process. |
