Convert maintenance costs to investment costs! After replacement, maintenance-free and energy-saving!

Situation
After the Great East Japan Earthquake, with all nuclear power plants halted, an old reducer for pulverizing mill drive had to operate at full capacity, leading to high maintenance costs.
The lack of load conditions, gear strength, and fitting dimensions made replacement consideration difficult.
Actions
Measured the existing stored parts, used past experience and knowledge to determine design conditions, proposed and executed a replacement without foundation modification, and achieved maintenance-free operation and significant power savings (12-14% reduction).
