Analysis and Numerical Calculation for Several Basic Characteristics of Coaxial Magnetic Gears Applied in Robots

Jixie chuandong
Due to its natural characteristics, coaxial magnetic gears are still difficult to be directly applied to industrial robots. Some key basic characteristics such as torque density, transmission ratio, null-space, backlash and torsional stiffness, and ...

Evaluation of Process Parameters for Integrated CO2 Electrolysis to Produce Ethylene

ChemistryOpen, Volume 15, Issue 2, February 2026.
This work systematically explores how flow rate, pressure, and temperature influence ethylene selectivity in integrated CO2 electrolysis with a potassium carbonate absorbent. Findings reveal that higher catholyte flow rates improves Faraday efficiency for ethylene by overcoming mass transport barriers, while increased pressure or temperature does not ...

Growth of Subsurface Fatigue Fractures in Large‐Size Bevel Gears

Fatigue &Fracture of Engineering Materials &Structures, Volume 49, Issue 2, Page 640-652, February 2026.
ABSTRACT Large‐size bevel gears are commonly used in marine industry for the applications of propulsion, such as azimuth thrusters. The gears are typically designed for specific use, as they are directly transferring power from one component to another.
