Simulating Gear Lubrication: Accurately Predicting Oil Flow Pattern, Temperature and Churning Losses
Gears systems are key mechanical components used to transmit power. They are used in many industry applications, including automotive and wind energy sectors . The most common application is in the automotive industry: The gear box (or transmission) converts energy from the internal combustion engine shaft to the drive of the wheels. In wind turbine applications, the gear box converts blade rotation speed (and its associated energy) to the rotation speed needed to entrain the power generator. Because of friction between gears, the gear system must be well lubricated to:
- Ensure that the gears maintain structural integrity (producing minimum friction for minimum mechanical losses, ensuring that gear teeth do not get damaged, etc.)
- Avoid oil over-heating: for example, gear box oil fires can occur on wind turbine installations
- Ensure minimal churning losses ( losses generated by oil’s being stirred by rotating gears)
ANSYS solutions offer a complete range of fluid dynamics simulation solutions for gear system lubrication.
- Complete geometry and meshing solution to capture even complex gear-tooth geometry
- Ability to handle all type of lubrication oils – even if you have proprietary oil properties
- Fast transient simulation capabilities that give fast results – the prediction of gear box lubrication performance
