The process of monitoring and diagnosis of planetary gearboxes is currently one of the most significant topics for vibroanalysis. The reason for ubiquitous research activities on the topic arises form a shortage of efficient method for a non-destructive thorough vibration analysis of planetary gearboxes, especially working under low speeds. On the other hand, the number of high-value planetary gearboxes working in industry rises rapidly, mainly due to expansion of wind farms. In the paper, the authors present a novel method for the assessment of the technical state of planetary gearboxes with a vibration sensor mounted on the casing, and without a planets position sensor. The method is based on the calculation of cyclic energy of gearbox teeth contact within consecutive carrier revolutions. The methods performance is illustrated on a real data from a wind turbine.
