In this paper, a Method of Analysis based on Computational Fluid Dynamics is presented to evaluate the behaviour of a lubrication circuit of a CVT gearbox. The study of lubrication in gearboxes is an important issue in off-road machines design because reliability depends mostly from lubrication performance, as well as machine lifetime and overall energy efficiency of the transmision. In the paper the methodology will be presented step-by-step and finally a complete map of operation condition will be disclosed. The result will be contextualized commenting the fluid dynamic phenomena involved and the influence of parameters on flow rate distribution.
