Planetary Gearboxes – A Brief Introduction to RPM, GMF and Ratio Calculations
This webinar will give a brief introduction to planetary gearboxes. Focus will be held on calculations for a simple planetary gearbox stage regarding RPM, GMF, ratios etc. An example with a multistage planetary gearbox will also be explored.

GMF Calculation and Gearbox Problems Detection
Gearbox defects can be identified with a quite high accuracy using vibration analysis. This is because the fact the most common defect frequencies are the fundamental Gear Mesh Frequency (GMF) and its harmonics (such 2x GMF, 3x GMF) which can easily detected.
