Prediction of oil distribution

Sufficient and reliable oil supply is essential in order to avoid gear and bearing damage under various operating conditions. The aim is to create a thin oil layer separating two components, thus minimizing wear, friction, and excessive heat generation.

The thermal management of the component is equally important for a long-lasting component. Furthermore, the lubricant’s additives play many different roles, ranging from corrosion inhibitor to antifoam to reliable abrasion setting.

Wetting analyses

Ensuring that all components are wetted properly is key, and it is critical to know early in your design process which regions are not sophistically lubricated. This should be known before you’ve built or even shipped your product. Why?

Your most precious resource is time. Minimize lost time by frontloading your development process with digital solutions. Frontloading also saves money, as we all know what a recall campaign of a whole gearbox series costs.

Roller Bearing Example

Bearings are the unnoticed stars in transmissions, always supporting the shafts by carrying axial and radial loads. Their durability and functionality must be reliable in all operating conditions. A major challenges for bearing lubrication is that many small surfaces are always in contact with the inner and outer rings. Analyzing the smallest fluid scales is critical and can be done effectively with particle-based fluid simulation.


Active lubrication

Active lubrication is an excellent method to precisely adjust the oil supply to the areas where it is required and avoid the costly churning of your high-speed gears through an oil bath. But which nozzles should you use to optimize the oil jet impingement on the gear teeth surface?

Shall I use a solid stream, full cone or flat fan nozzle? And, is it even worth it to install the oil-pump or is a bath lubrication the most beneficial option after all?

General guidelines are acceptable, and your internal knowledge is sophisticated, but this topic becomes relevant every time you develop a new application, so evaluating these design possibilities beforehand will foster your strategic advantage in the market.


It’s no secret that mechanical components last longer if they stay cool. But the story is more diverse for gearboxes: The mechanical engine power is partially converted into heat while being transformed at the gear stages – components become hotter, and their structure becomes weaker. How to transport this heat to the ambience? With the lubricant! Easy, right?

But we all know that too much oil only leads to more issues: a blocked breather might reduce ventilation cooling, the cold start may not work as planned, or the lubricant properties may change drastically with higher or lower temperatures, causing the lubrication functionality to fail. Temperature effects are complex, and a reliable monitoring tool is essential.

Efficiency optimization

Transmissions distribute excessive loads within your machinery by converting momentum and rotational speed to the desired ratio. For all mechanical systems, these processes come with unwanted heat generation due to the friction within the highly loaded contacting components, the squeezing of the
lubricant in between the contact zones, and the splashing of the lubricant-air mixture inside the gearbox.

Again, sufficient oil supply is critical, but an oversupply results in excessive losses. Progressive mechanical engineering designs target the highest possible energy efficiency and raw material sustainability, rendering conservative approaches as obsolete.

Total & Local Power Loss

Especially for situations where rotational speed is high and load is low (like driving on the highway in the top gear), powering the lubricant’s motion becomes prominent in the power balance. The first step is to understand how much power is required, the next is to analyze it by component, and the last is to optimize the loss distribution on a component level.

How do we do it?

We use the integral boundary approach
which works directly with the triangle surface
mesh. This makes it possible to accurately
represent the gears and the meshing zone.

Look at the video showing how easy it is to upload
a standard STL file
and set the movements. On
top of that, you can use Python script to
automate the process

Thanks to the triangle-based boundary conditions, results are highly accurate. Accurate geometry means better results.

Complex multiphase flows

Why does it matter?

The rule of thumb is that windage phenomena becomes prominent at around 20(25) m/s pitch line velocity. At this velocity, it is necessary to use simulation in order to optimize your lubrication. Why is that so?

First, larger inertia of the oil phase during the gear rotation leads to the oil being thrown of radially and, second, an air cushion is formed in between gears teeth. With the air shielding the gear, oil in the bath as well as airborne oil droplets are deflected.

Our sophisticated multiphase approach has you covered whenever you analyze these situations.

How do we do it?

Multiphase flows can be simulated in just a few clicks, as shown in this example video. Just add air as a second filling, move the seed point to desired space and that's it. If you want to see particles, click discretize.

Have a look at how the oil is mixing with the air and compare with your single-phase results!

Any Type of Gearboxes

Selecting the correct gear set for your application, defining the housing geometry, choosing the material and surface finishes. These are costly and critical parts of your work, and the final designs vary a lot! What do they all have in common? A lubrication system! The advantage of CFD? It gives you the power to analyze every lubrication system independent of the chosen gear set.

Various Gearbox Types

Spur gears, helical gears, bevel gears, epicyclic gears, worm gears: the list goes on! Even complex setups can be analyzed through various interfaces.

Dip & Jet Lubrication

Is dipping the gears into the oil sump not satisfying your needs? You can create a solid stream with a full cone or flat fan nozzle and even simulate moving oil nozzles.

Physical Material Parameters

What about other influential parameters like varying RPMs, low and high temperatures, thin and thick oils, too much or too little oil? These can all be defined within our tool.

Have a look at the oil squeezing between the teeth. The fluid is radially thrown away by the wheel and the surface tension determines the flow pattern. Beautiful.
