Passive Suppression of Planetary Gear Transmission Vibration via Discrete Boundary Struts

Proceedings of the Vertical Flight Society 72nd Annual Forum, 2016
This paper investigates a passive vibration suppression method for planetary gear transmissions by establishing a new PGT structural dynamics model with elastic ring gear supported by discrete boundary struts.

Differential Planetary Gear Transmissions Usable in Renewable Energy Systems

2011
Many of the renewable energy systems (RES) use planetary gears for the speed increase or reduction. The paper presents a 2 DOF planetary gear transmission to be used as “speed increaser” in the counter-rotating wind turbines, hydropower plants, and, also as “speed reducer”, in the tracking systems that equip the solar photovoltaic or solar thermal ...

Load capacity of planetary transmission with internal gear engagement

Russian Engineering Research, 2011
An analytical method is proposed for determining the load capacity of a planetary transmission with internal gear engagement. The method is based on solving the compatibility equations of the displacement of the engaged teeth.

Coupled two-carrier planetary gears for two-speed transmissions

Mašinostroitelna tehnika i tehnologii, 2007
In following the article two-speed planetary gearboxes consisting of two simple planetary gears and two brakes are examined. A review is made on the possible ways of connecting the coupling gears and the brakes. Some relations are deduced for determining the speed ratios of all structural schemes. Relations are deduced for determining the efficiency of
