Analysis of the efficiency of wind turbine gearboxes using the temperature variable [PDF]

open access: yes, 2019
The aim of this paper is to evaluate how lubricant selection affects gearbox efficiency and overall energy production by analysing real data from wind farms, monitored and controlled by a Supervisory Control and Data Acquisition (SCADA system).

Parametric oscillations in planetary wheel gearboxes

open access: yesBulletin of the National Technical University «KhPI» Series: Engineering and CAD, 2018
Разработана математическая модель параметрических колебаний в планетарных колесных редукторах (ПКР) троллейбусов. Модель учитывает циклические деформации тонкостенного обода и зубьев в зацеплении эпицикла с сателлитами. Дифференциальное уравнение колебаний эпицикла приведено к виду уравнений Матье-Хилла с переменными периодическими коэффициентами.

Resonance-based sparse adaptive variational mode decomposition and its application to the feature extraction of planetary gearboxes.

open access: yesPLoS ONE, 2020
Due to the assumption that the VMD technique is essentially a set of adaptive Wiener filter banks and its performance depends to a large extent on the preset parameter K (the number of decomposition).

Planet Bearing Design of Slewing Planetary Gearbox [PDF]

open access: yesJournal of manufacturing engineering & technology, 2012
AbstractIn order to meet the service life of planetary gearbox, a planet bearing, well known as the component with the highest failure rate, is designed. To predict the bearing fatigue life, ISO standard(ISO/TS 16281) is used, and the design parameters of the bearing are optimized using a parametric method.
