Case Study: D-I Industrial Co. Limited improves gearbox design and reduces gear whine with Romax Technology

Romax enables leading Korean marine transmission developer, D-I Industrial, to improve product quality and deliver innovation for customers

D-I Industrial Co. Limited, South Korea’s leading manufacturer of hydraulic marine transmissions, speed reducers, steering systems and PTOs, wanted a more systematic, whole-system approach to powertrain design that would better account for interactions between gears, shafts, and other components. To address this challenge, the company turned to Romax Technology and its RomaxDESIGNER software for root cause analysis, design optimisation, and gear whine reduction.

Romax Technology helped D-I Industrial use simulation-driven design review and micro-geometry optimisation to identify design errors earlier, reduce tooth damage and transmission error, and cut gear whine. The result was faster gearbox design reviews, lower time and cost in development, improved product quality, and new opportunities to assess bearing life, gear rating, housing strain analysis, and other factors.
