    Yes, you can perform gearbox efficiency analysis in Romax. The software provides dedicated tools and workflows for calculating gearbox efficiency. The efficiency analysis takes into account a wide range of gearbox components, such as gears, bearings, seals, clutches, and even the lubricant properties. The choice of lubricant and its properties (viscosity, pressure-viscosity coefficient, etc.) directly affect gear and bearing losses, especially when using the FVA-345 method. Romax does take into account of lubricant properties in efficiency calculation. 

     

    Components considered in Romax 

    1) Gears - Gear mesh losses are calculated using various models, including ISO 14179-1/2, Anderson, and the advanced FVA-345 method, which incorporates lubricant properties and micro-geometry effects. Gear blank (churning/drag) losses are also considered.

    2)Bearing- Bearing drag losses are calculated using models such as ISO 14179-1/2, Palmgren, SKF, and Romax's advanced bearing drag model, which accounts for misalignment and load distribution.

    3)Seal-Seal friction losses are included, with models based on ISO 14179-1/2.

    4)Clutch- User defined efficiency can be considered

     

    NOTE- You need "Romax Energy" license to perform efficiency analysis.
