摘要：
The film thickness and the traction curves of four fully formulated wind turbine gear oils were measured on a ball-on-disc device. All oils have the same viscosity grade (ISO VG 320) and different formulations: ester, mineral, PAO and mineral+PAMA. Film thickness and traction coefficient results will be presented. The film thickness measurements were compared with predictions using film thickness equations from the literature. (C) 2015 Elsevier Ltd. All rights reserved.
