Analysis of planetary gear transmission in non-stationary operations
Frontiers of Mechanical Engineering, 2013Planetary gearboxes operate usually in nonstationary conditions generated mainly by variable loads applied to these transmissions. In order to understand the dynamic behavior of planetary gearboxes in such conditions, a mathematic model is developed including driving unit, transmission and load.

Modal Analysis on Transmission Gear Train of Planetary Reducer
Advanced Materials Research, 2012The planetary reducer has both internal incentive of varying mesh stiffness and external incentive of eccentric quality, which are prone to vibration and noise at work. This paper use ANSYS Workbench to build model, divide grid and carry out modal analysis for transmission gear train of Planetary reducer, and calculate the 6 order modes.

Study on the inherent characteristics of planetary gear transmissions
2015 21st International Conference on Automation and Computing (ICAC), 2015This article describes a novel modeling method for a rigid-flexible coupled planetary gear transmission system, which consists of rigid and elastic ring gear subsystems. The rigid gear subsystem model was established using the lumped parameter method while the elastic ring gear subsystem was established using the finite element method. According to the

Calculating planetary gear transmission parameters for the reduction gears in worm centrifuges
Chemical and Petroleum Engineering, 2009Descriptions are given of the features and shortcomings of various geometrical calculations on evolvent gear transmissions for internal coupling, as used in worm centrifuge reduction gears. A scheme is proposed for calculating the tooth interference of the wheels by means of the Mathematica program.

High Performance Planetary Gears for Heavy Duty Automotive Transmissions
SAE Technical Paper Series, 2005<div class="htmlview paragraph">Planetary gears in heavy truck gearboxes are normally manufactured by forging a blank, turning, hobbing, shaving and heat-treatment followed by grinding. Due to the size of the gear the net shape capability of PM methods can be cost effective alternatively to conventional manufacturing.
