WIL develops gearboxes for almost every application. WIL has supplied and serviced Gear Boxes for Sugar, Cement, Steel, Paper, Hydel, Fertilizer and Petro-chemical industry along with Power sector. It has also made forays in Defence sector by providing Main Propulsion Gear boxes for almost every type of ship for Indian Navy.
Gear Box development involves the following
- Thoroughly understand the application and process.
- Size and Analyze the configuration.
- Design all the components and their interconnections.
- Analyze the performance of the system including prime mover, Gearbox and driven equipment.
- Optimize the sizes & geometries for the best operating performance of the total system.
- Match the performance with the driven and driving machines for the best overall results.
