Development of an Oil Free Water-Based Lubricant for Gear Applications
Lubricants, 2019 The aim of the current research is to develop a gear transmission fluid based on water and plant extract. Up to now, mineral or synthetic oils are used as lubricants in most gear drive applications. These oils are made of fossil raw materials and are non-

Numerical Visualization of Grease Flow in a Gearbox
Chinese Journal of Mechanical Engineering, 2023 Lubricating greases are widely used in e.g. open gear drives and gearboxes with difficult sealing conditions. The efficiency and heat balance of grease-lubricated gearboxes depend strongly on the lubrication mechanisms channeling and circulating, for ...

Parameter study on the calculated risk of tooth flank fracture of case hardened gears
Journal of Advanced Mechanical Design, Systems, and Manufacturing, 2017 Due to better material qualities, new surface finishing methods and better heat-treatment process reliability, flank surface damages, such as pitting or micropitting, can be prevented in a reliable manner.

ABENICS: Active Ball Joint Mechanism With Three-DoF Based on Spherical Gear Meshings
IEEE Transactions on robotics, 2021 This article presents an active ball joint mechanism (ABENICS) enhanced by interactions of spherical gears. The gear-based joint drives three rotational degrees of freedom (RDoF) without slippage. The capabilities were inspired by the unique interactions

Coarse Projective kMC Integration: Forward/Reverse Initial and Boundary Value Problems [PDF]
, 2003 In "equation-free" multiscale computation a dynamic model is given at a fine, microscopic level; yet we believe that its coarse-grained, macroscopic dynamics can be described by closed equations involving only coarse variables.

Experimental analysis of oil flow and drag torque generation in disengaged wet clutches
Scientific Reports, 2023 Fundamental knowledge of the oil flow in a disengaged wet clutch is essential for optimizing the cooling performance and the drag losses. However, no fundamental information on the oil flow and drag torque generation is available for dip-lubricated wet ...
