Kinematics, efficiency and dynamic balancing of a planetary gear train based on nutating bevel gears

摘要

The article discusses the main functional characteristics of a planetary gear train based on nutating bevel gears. System geometry, design parameters, kinematics and efficiency expressions in term of such parameters are presented. Then, an analytical model of its dynamics is developed and explicit balancing conditions to eliminate the effect of internal inertial forces are obtained. Analytical results regarding dynamics and balancing criteria are verified through multibody simulations on a sample geometry. A discussion about how to determine balancing geometries is finally carried out.
