Geometry Modification of Helical Gear for Reduction of Static Transmission Error [PDF]
MATEC Web of Conferences, 2018 Gear systems are extensively employed in mechanical systems since they allow the transfer of power with a variety of gear ratios. So gears cause the inherent deflections and deformations due to the high pressure which occurs between the meshing teeth ...

Study on the Variation Law of Static Transmission Error for Cylindrical Gear
Jixie chuandong, 2017 Based on a modified thin slice method,the static transmission error of cylindrical gear pair with tooth surface error is calculated efficiently. The transmission error is separated into composite deformation and composite mesh error,and the change of ...

Determination of static transmission error of helical gears using finite element analysis [PDF]
Journal of Measurements in Engineering, 2020 At present, increasing emphasis is being placed on low noise levels, especially in the automotive industry. One of the dominant sources of noise (and vibration) in vehicles (with an electric motor as well as an internal combustion engine) is the transmission system.

On the frame error rate of transmission schemes on quasi-static fading channels [PDF]
2008 42nd Annual Conference on Information Sciences and Systems, 2008 It is known that the frame error rate of turbo codes on quasi-static fading channels can be accurately approximated using the convergence threshold of the corresponding iterative decoder. This paper considers quasi-static fading channels and demonstrates that non-iterative schemes can also be characterized by a similar threshold based on which their ...
