Scuffing load capacity calculation of worm gears [PDF]
Forschung im Ingenieurwesen, 2021 AbstractWorm gears with wheels of harder materials, such as cast iron or steel, are often prone to the damage type scuffing, which can cause a sudden and rapid failure of the gear box. Contact temperature is a suitable criterion to determine the scuffing safety for other types of gears.

Materialwissenschaft und Werkstofftechnik, Volume 54, Issue 11, Page 1390-1399, November 2023., 2023 Growing demand for sustainability and toxicologically questionable mineral oil‐based lubricants are leading to a focus on sustainable lubricants for electromechanical drive systems. Reducing friction and wear, increasing oxidation resistance and reducing viscosity lead to lower energy consumption of the drive system. Lubricant stability under high load

Mitigation of transient torque reversals in indirect drive wind turbine drivetrains
Wind Energy, Volume 26, Issue 8, Page 803-825, August 2023., 2023 Abstract Bearing failure in wind turbine gearboxes is one of the significant sources of downtime. While it is well‐known that bearing failures cause the largest downtime, the failure cause(s) is often elusive. The bearings are designed to satisfy their rolling contact fatigue (RCF) life. However, they often undergo sudden and rapid failure within a few

Transient torque reversals in indirect drive wind turbines
Wind Energy, Volume 26, Issue 7, Page 691-716, July 2023., 2023 Abstract The adverse effect of transient torque reversals (TTRs) on wind turbine gearboxes can be severe due to their magnitude and rapid occurrence compared with other equipment. The primary damage is caused to the bearings as the bearing loaded zone rapidly changes its direction.

BUMPY ROADS, DUSTY AIR: Gadbad and the Sensate Ecologies of Driving Work in Contemporary Mumbai
Cultural Anthropology, Volume 38, Issue 1, Page 60-86, February 2023., 2023 ABSTRACT I decouple the commonly discussed ecological destruction and unsustainability wrought by cars from a discussion of what life lived and sustained around automobiles looks like. Through fieldwork with hereditary Muslim taxi drivers in Mumbai, I look at urban ecological relations with those who work in what I call sensate ecologies.

Recent Progress on Carbon Nanomaterials for Resisting the Wear Damages
Journal of Nanomaterials, Volume 2022, Issue 1, 2022., 2022 In recent years, carbon nanomaterials such as fullerenes, carbon nanotubes, graphene, and nanodiamonds have been regarded as versatile triboproducts such as copper coins for various engineering/commerce‐scaled applications. Their large‐scale usages as ideal reinforcements for the key tribomaterials are motivated by their huge interfacial areas, unique ...

Bulk temperature measurements on gears for scuffing monitoring
, 2010 Gear bulk temperature is the steady temperature of the gear teeth before they enter the contact zone. Generally, it can be appreciably higher than lubricant inlet temperature supplied to the gear mesh.
