Jeep parent Stellantis might take a system that's drawn comparisons to Toyota's original planetary-gearset hybrid layout on to new off-road adventures.

Packing a compact design, along with high torque and low-speed outputs, the new SEW PPK and SEW P2.e planetary gear units from SEW-EURODRIVE offer new capabilities in continuous heavy duty ...

Planetary gear transmission systems, integral to helicopter main reducers, significantly impact the reliability and service life of helicopters due to their vibration and noise. Developing a ...

The dynamic properties of gear transmission systems can influence the stability and reliability of gear mechanisms. Hence, investigating the nonlinear dynamic characteristics of planetary-face gear ...

Wirecutter’s senior editor for smart-home and audio/video (who is also a casual “Paranormal Activity” fan) put some of the most common ghost tech to the test.

This paper proposes a method for separating instantaneous angular speed (IAS) signals for planetary gear fault diagnosis. Firstly, this method obtains encoder pulse signals through a built-in encoder.

Early automatic transmissions with names like Hydra-Matic, Dynaflow, ZF, and Hondamatic delivered simplistic driving, but heavy planetary gear systems and torque converters sacrificed fuel efficiency.

Transmission efficiency is a key parameter of planetary gear train, it has a significant effect on power density of transmission systems. Usually, ring gear is regard as a rigid part in the efficiency ...
