Tiivistelmä
This thesis was commissioned by Wärtsilä Finland Oy. The aim was to design a gear-driven balancing system to replace the belt-driven balancing system used in Wärtsilä's 46F and 46DF engines.
The design of the new gear-driven balancing system is a very extensive process and involves many different aspects. In this thesis, the topic is limited so that only the design and dimensioning of the gears and bearings were studied carefully. The gears were dimensioned according to the required transmission ratio and the strength of the gear wheels was examined using the KISSsoft simulation software. When selecting the appropriate bearing type, the load situation was considered and bearing solutions were taken into account in the corresponding balancing system of Wärtsilä's 46TS engine.
In addition to the theoretical calculation part, a 3D model of the new system was created, presenting the system as a whole at the concept level. The solutions made during the work are visible in the model and it serves as a starting point for further design of the system.
