Abstract (EN): This work evaluates the performance of different ISO VG 320 wind turbine gear oils with base oil formulations based in PAO, Mineral, Ester and PAG having quite different viscosity indexes. The oils evaluation was done in rolling bearing tests and gearbox tests. Their behaviour was compared for operating conditions in the range of the observable in a wind turbine gearbox. The experimental results showed considerable differences between the different oils and it was observed that depending on the contact type the relative behaviour of the lubricants would change, i.e. the best lubricant for the rolling bearing would not imply the best result on the gearbox tests. The gear geometry is also a very important parameter on a gear transmission torque loss. It was observed that a decrease of up to 25% in torque loss could be achieved with a low loss gear geometry. Numerical models were implemented and calibrated with the purpose of obtain the friction coefficient promoted by the tested oils and performing a better simulation of the mechanical system.
