Influence of Planet Carrier Misalignments on the Operational Behavior of Planetary Gearboxes

The article "Influence of Planet Carrier Misalignments on the Operational Behavior of Planetary Gearboxes" appeared in the July 2020 issue of Gear Technology.

Summary
This study deals with the modeling and consideration of misalignments in planetary gearboxes in the optimization and design process. Procedures for taking into account misalignments in cylindrical gearboxes are standardized and established in industry. Misalignments of central elements like carrier, sun gear or ring gear in planetary gearboxes, cause varying contact positions and variable loads, depending on the angular position of the central elements. This load, which is variable over the circumference, is not taken into account in the standardized procedures, despite its effects on the loads on the gears.
