Determination of Load Distributions on Double Helical-Geared Planetary Gearboxes - June 2017

Tobias Schulze

The article "Determination of Load Distributions on Double Helical-Geared Planetary Gearboxes" appeared in the June 2017 issue of Power Transmission Engineering.

Summary
Standardized calculation methods such as ISO 6336 and DIN 3990 already exist to determine the load distributions on gears inside a planetary gearbox, but by their very universal nature, these methods offer varying results depending on the gearbox design. Double helical gears, in particular, can benefit from more specific, complex algorithms to reach a maximum level of efficiency. Double helical gears interact with the rest of the gearbox differently than helical or spur gears, and thus benefit from different analytical models outside the standardized methods. The present research project describes the algorithm to determine the load distribution of planetary gearboxes with double helical gears.
