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 ...

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.

Static transmission error measurement of various gear-shaft systems by finite element analysis [PDF]
Journal of Measurements in Engineering, 2023 Transmission error (TE) is a significant parameter related to gears vibration widely investigated by many authors using different approaches. However, in previous studies, spur and helical gears were mainly examined. There is a lack of studies addressed to double helical and herringbone gears and a comparison among several types of gearing with ...

Influence of Sine-Shaped Profile Deviations on Static Transmission Error [PDF]
Engineering MechanicsTransmission error (TE), a parameter influencing gears vibration and subsequent noise, is a subject addressed in many papers. However, most researchers consider ideal or modified involute while neglecting machining errors. This case study extends the author’s previous work (Czakó et al., 2020) by incorporating tooth profile errors and investigating ...

Research on Quasi-Static Transmission Error Measurement of Spur Gears Based on the Acceleration Method [PDF]
MachinesTransmission error (TE) is an important parameter in gear dynamics that has a direct impact on the vibration and noise of gears. Under quasi-static conditions, gear elastic deformation and assembly errors amplify with increasing load, potentially ...

Influence of Surface Pitting and Friction Coefficient on the Static Transmission Error in Spur Gears
International Journal of Mechanical Engineering and Robotics Research, 2020 This research studies the performance characteristic, Static Transmission Error (STE), of a spur gear pair rotating under friction with and without damage in the form of a pit on gear teeth. Using a profilometer scan of a pit from an aerospace test gear,

Dynamic analysis of high speed gears by using loaded static transmission error
Journal of Sound and Vibration, 1988 Abstract A single degree of freedom non-linear model is used for the dynamic analysis of a gear pair. Two methods are suggested and a computer program is developed for calculating the dynamic mesh and tooth forces, dynamic factors based on stresses, and dynamic transmission error from measured or calculated loaded static transmission errors.
