Gear Tooth Root Bending Strength Estimation under the Assumption of Fatigue Limit Existence
Material Design &Processing Communication, Volume 2022, Issue 1, 2022., 2022 Being able to properly predict gear failure is a key aspect to achieve a reliable light‐weight gearbox. Among the several gear failures, tooth root bending fatigue is considered as the most dangerous one because it implies the stoppage of the whole gearbox.

Minimum Friction Losses in Planetary Stages of Wind Turbine Gearboxes
Mathematical Problems in Engineering, Volume 2022, Issue 1, 2022., 2022 Mechanical efficiency is not a critical design factor of wind turbine gearboxes since wind energy is abundant and costless. The design and sizing of the gears will be determined by the requirements of power density, gear ratio, fatigue safety, and allowable noise and vibration levels.

Shock and Vibration, Volume 2022, Issue 1, 2022., 2022 Beveloid gears are usually employed to transfer motion of small shaft angle, but the assembly errors or misalignment can affect the gear tooth contact and dynamic performance. A dynamic model and tooth contact analysis model of the intersecting beveloid gear pair are established, the defects of the theoretical tooth surface in the meshing are analyzed,

Mathematical Problems in Engineering, Volume 2021, Issue 1, 2021., 2021 Spur gears are an indispensable element of power transmission, most of the time used in small environments with severe operating conditions such as high temperature, vibrations, and humidity. For this reason, manufacturers and transmission designers are required to look for better gear designs and higher efficiency.

Transferability of the scuffing load capacity of gear oils determined on spur gears to hypoid gears
Forschung im Ingenieurwesen, 2023 AbstractThe scuffing load carrying capacity is a decisive design criterion in the development of gears. In addition to the gear geometry, the entire tribological system of the gearbox must also be taken into account. Besides the loads and speeds occuring during the operation of the gears, the lubricant used and its additives have a significant ...
