International Journal of Mechanical System Dynamics, Volume 3, Issue 2, Page 173-182, June 2023., 2023 Abstract Microscopic roughness is inevitable on the gear meshing surface, which is also a key parameter affecting the dynamic response. The surface roughness exhibits self‐affine characteristics across multiscales. To explore the influence of surface fractal topography on the vibration amplitude of the gear system under different rotational speeds and ...

Shock and Vibration, Volume 2022, Issue 1, 2022., 2022 The gear‐bearing system is the most important part of integrally centrifugal compressors. According to statistics, the majority of integrally geared compressor accidents are caused by excessive vibration of the geared rotor. However, its complicated dynamic characteristics and inevitable vibration faults in actual operation present significant ...

Mathematical Problems in Engineering, Volume 2020, Issue 1, 2020., 2020 The actual contact point of a spiral bevel gear pair deviates from the theoretical contact point due to the gear deformation caused by the load. However, changes in meshing characteristics due to the migration of contact points are often ignored in previous studies on the elastohydrodynamic lubrication (EHL) analysis of spiral bevel gears.

On Dynamic Mesh Force Evaluation of Spiral Bevel Gears
Shock and Vibration, Volume 2019, Issue 1, 2019., 2019 The mesh model and mesh stiffness representation are the two main factors affecting the calculation method and the results of the dynamic mesh force. Comparative studies considering the two factors are performed to explore appropriate approaches to estimate the dynamic meshing load on each contacting tooth flank of spiral bevel gears.
