Asymmetric Gear Noise Sidebands and Application to Planetary Gear Noise Reduction
SAE Technical Paper Series, 2005<div class="htmlview paragraph">Asymmetric sidebands of gear noise are frequently observed with a planetary gear set, and are different from typical sidebands that are symmetrical around the gear mesh order (or mesh frequency). The asymmetric sidebands are found to be caused by phase differences between the different mesh points.

Terminology and Design of Asymmetrical Gears for Aircraft
2015Main calculation principle of gear wheel geometry with asymmetrical tooth profile is presented. The paper presents calculation of bending stresses by means of YFS coefficient which takes into account the tooth shape and stress concentration. Graphic method of YFS coefficients calculation is described.

Asymmetric Gears: Parameter Selection Approach
Applied Mechanics and Materials, 2011In many gear transmissions the tooth load on one flank is significantly higher and is applied for longer periods of time than for the opposite one. An asymmetric tooth shape reflects this functional difference. This paper describes an approach to rationalize the asymmetric gears parameter selection to meet a variety of operating conditions and ...

Design and Analysis of Asymmetrical Spur Gear Drive for Automobile Gear Box Application
Applied Mechanics and Materials, 2014This work mainly aims to explore the actual load, fillet and contact stresses induced during a mesh cycle in a spur gear tooth. As the mesh stiffness differs at different contact points along the path of contact, it significantly affects the load sharing between the simultaneously meshed contact pairs hence stresses.

Determination of load dependent gear loss factor on asymmetric spur gear
Mechanism and Machine Theory, 2019Abstract This paper shows the prediction of coefficient of friction and load dependent loss factor for spur gear drives with asymmetric tooth. An accurate evaluation of gear loss factor is important to exactly calculate the power loss and the corresponding mechanical efficiency of the asymmetric spur gear drive.

Application, synthesis, and manufacture of involute gear transmissions with asymmetric gear profiles
Russian Engineering Research, 2009By investigating possible applications of involute gear transmissions with asymmetric gear profiles, three levels of transmissions may be identified. Each level is characterized by a particular set of engagement angles, operational parameters, types of gear, and manufacturing methods.

Experimental and Probabilistic Analysis of Asymmetric Gear Tooth
2011Photoelasticity has been used previously in experimental studies on gears. With the advantages of today’s high capability of computing and software, photoelastic analysis can be combined with probabilistic analysis. The objective of this study was to perform an experimental study and probabilistic analysis of an asymmetric gear tooth.

Study on an internal gear with asymmetric involute teeth
Mechanism and Machine Theory, 2007Abstract In this paper, a double envelope concept is used to determine the basic profile of an internal gear with asymmetric involute teeth including driving and driven gears. The teeth of the proposed gear are asymmetric involute teeth. Based on this concept, a mathematical model of the meshing principles of a driven gear meshed with a driving gear ...
