Optimization of Involute Gear Tooth Profile Modification for Tooth Scoring Reduction
6th International Power Transmission and Gearing Conference: Advancing Power Transmission Into the 21st Century, 1992Abstract This paper presents a method for determining optimum involute tooth profile modifications to reduce scoring and to increase load bearing capacity. The method is based upon Bloks theory of lubrication and wear. The method leads to design charts incorporating common geometrical gearing parameters. An example is presented.

A Study on Planetary Gear Dynamics With Tooth Profile Modification
Volume 8: 11th International Power Transmission and Gearing Conference; 13th International Conference on Advanced Vehicle and Tire Technologies, 2011This study investigates the impact of tooth profile modification on planetary gear dynamic response. Micro-scale geometric deviations from an involute gear tooth profile add an additional excitation source, potentially reducing gear vibration. In order to take account of the excitation, tooth profile modification is included in an analytical planetary ...

Influence of Tooth Profile Modification on Helical Gear Durability
Journal of Mechanical Design, 2002A nonlinear finite element contact mechanics model of a helical gear pair was used to study the effect of intentional tooth profile modifications on durability of helical gear pairs. Both two-dimensional (2D) and three-dimensional (3D) modifications were considered.

Forschung im Ingenieurwesen, 2019
In the previous study, the authors showed the results that the cycloid gear pair with tooth number difference of two does not only increase the contact ratio and decrease the maximum shared load of the individual contact tooth pair, but also reduce the bearing loads of the cranks slightly.

The optimisation of bevel gear tooth in mesh with various types of profile modifications
International Journal of Modelling, Identification and Control, 2010According to the relationship between the torsional mesh stiffness and the noise, the use of a rotated original tooth profile, circular curve and line curve as the form of the modified profile curve respectively is developed for bevel gear in order to depress the vibration and decrease the noise.

Tooth Profile Modification of Sprocket in Dual Meshing Silent Chain
Advanced Materials Research, 2012Dual meshing silent chain mechanism can reduce the polygon action. In order to realize the conjugate meshing, the sprocket of the dual meshing silent chain mechanism is supposed to be an involute sprocket with a large pressure angle and negative modifying coefficient.
