Study and optimization of rotors for oil pumps for automotive use

Research activity carried out for Salei-SIL Lumezzane (Brescia), in collaboration with the Department of Mechanical and Industrial Engineering of the University of Brescia.

The first objective of the work is to identify a general mathematical methodology for the synthesis of the profile of the gerotor pump. The classic approach allows to generate profiles from typical circular generating curves; We want to extend the methodology to generally complex geometric shapes describable by Bezier curves.

The generation of the procedure brings with it a greater flexibility in the form of the obtained profiles and therefore a greater freedom of choice of the profile that best respects the specific needs to which the pump will have to face. We want to propose an automatic search for the best solution.

The features for pumps are the following:

-Low noise

– Wear and tear

-High Efficiencies

– Respect to cylinder displacements and maximum dimensions.

We intend to propose a methodology of excellent.
