Gear Oiling


Merke & Partner is the world leader in the simulation of oil distribution in transmissions.

We use a wide range of processes for the most diverse transmissions, depending on what the problem is.


The physics involved in simulating the distribution of oil in the gearbox is very complex: moving grids, multi-phase (air and oil), narrow gaps, complex geometry, longer periods of time to be considered, influence of temperature on oil properties. Not to forget the acceleration loads in the automotive sector (cornering, acceleration and braking).

And granted, a glass gear in the test is not really sparkling, is it?
The topic is predestined for us, as we have a head start and will maintain it.

Many well-known OEM’s rely on our expertise here.
We are happy to help you build more efficient transmissions and meet your CO² requirements.


Why are such simulations performed?

It’s quite simple: If I have too much oil in the gearbox, the efficiency drops and the losses increase.
If I have too little oil or not enough oil on some bearings, the bearing jams and the gearbox is defective.

The oil also has the task of dissipating heat.

The aim is therefore to achieve optimum efficiency with sufficient lubrication and cooling of all bearings and gear pairs.
