Planetary gear sets are suitable for high power density and gear ratio, but this means high
torques and stress levels. Though the torque is transmitted between multiple planets, it is not …

Spur gears are widely applied in transmissions of heavy load cases, such as turbines, ships,
mining devices, and other industrial applications. Increasing the tooth root bending strength …

An efficient model is introduced for evaluating the load distribution of helical gears,
considering tooth modifications and misalignment errors. Instant contact points are obtained …

Gear wear is unavoidable and results in vibrations and decreased performance in a
planetary gear system. In this work, the wear phenomenon of the gear teeth surface and the …

行星齿轮磨损会导致齿轮齿侧间隙非线性增大, 传动精度下降, 齿面冲击力增大,
进而会导致齿轮传动系统振动加剧, 因此需要对行星齿轮的齿面磨损与动力学耦合特性进行研究 …

An enhanced model for strength calculations of internal spur gear pairs is presented. The
load sharing among couples of teeth in simultaneous contact is determined from the …

An accurate calculation of the maximum tooth root stress (TRS) and critical section location
(CSL) provides a basis for predicting and improving gear performance. The irregular profile …

High contact ratio gears are being increasingly used in a large number of mechanical
systems, because of their advantages with regard to lightweight design. Their main …

The influence of the teeth geometry on the load distribution, transmission error, and meshing
stiffness of internal spur gears is very similar to that of external gears. Therefore, the …

Although the load sharing between planets of sequentially phased planetary gear
transmissions has been studied in the past, the required solving techniques based on the …
