Analysis on Transmission Efficiency of Planetary Gear Reducer

Applied Mechanics and Materials, 2014
A transmission efficiency calculation model of planetary geared reducer was proposed in this paper. The power losses of meshed surfaces of sun-planet gears and planet-ring gears were analyzed in detail. Finally, the mechanical power losses and transmission efficiency of the planetary gear reducer were simulated to illustrate the influence of rotational

Study on Parametric Drawing of Planetary Gear Transmission

Advanced Materials Research, 2011
In the planetary gear transmission design, the structure and shape of some major parts are often the same or similar, tedious and duplicate drawing may reduce the drawing efficiency. This paper studies redevelopment technology by using Visual Lisp language in AutoCAD platform, and compiles drawing programs to realize parametric drawing.

Dynamic Modelling of Planetary Gears of Automatic Transmissions

Proceedings of the Institution of Mechanical Engineers, Part K: Journal of Multi-body Dynamics, 2008
In this paper, a generalized dynamic model for multi-stage planetary gear trains of automotive automatic transmissions is proposed. The planetary gear train is formed by N number of planetary gear sets of different types (single-planet, double-planet, or complex-compound), connected to each other in any given kinematic configuration. In addition, each

Initial impact force analysis and simulation of planetary helical gear transmission

Proceedings of the Institution of Mechanical Engineers, Part C: Journal of Mechanical Engineering Science, 2023
The planetary gear transmission is widely used because of its advantages such as large transmission ratio and high transmission efficiency. But at the moment of starting, there is a speed difference between driving gear and driven wheel due to the ...

Experimental Analysis of Gear Loading in Planetary Transmission

Applied Mechanics and Materials, 2015
This paper is focused on examination of teeth loading in rotating gears during standard operation and describes the applied approach and device developed. One of the closely examined items in planetary transmission testing is the gearing. The tooth load of each wheel in planetary transmission is monitored individually.

Modeling and Dynamic Characteristics of Planetary Gear Transmission in Non-inertial System of Aerospace Environment

Journal of Mechanical Design, 2019
The traditional research on the dynamics of planetary gear transmission (PGT) is based on the assumption that the support is on the ground. However, the PGT inside the aircraft is spatially moved along with the airframe, which is not only subject to ...

Analysis of an Improved Planetary Gear-Transmission Bearing

Journal of Basic Engineering, 1964
In planetary-gear transmissions, especially for aircraft applications, the planet gears are frequently made integral with the outer rings of rolling bearings. Thus the outer ring of the rolling bearing is subjected to the tangential, radial, and moment loading attendant to spur gears.

Development of New Magnetic Planetary Gears for Transmission Systems

INTERMAG 2006 - IEEE International Magnetics Conference, 2006
In this paper, a novel magnetic planetary gear (MPG) is proposed and illustrated, which is composed of one magnetic sun gear, one magnetic ring gear, and three magnetic planet gears. Because the contact-free gear structure results in lower stiffness, proper design methods are needed to improve gear properties.
