Effect of two synthetic lubricants on life of AISI 9310 spur gears [PDF]
Spur-gear fatigue tests were conducted with two lubricants using a single lot of consumable-electrode vacuum-melted (CVM) AISI 9310 spur gears. The gears were case carburized and hardened to Rockwell C60. The gear pitch diameter was 8.89 cm.

Multidexterity: Reframing Strategic Agility for Hyper‐Transformation
Strategic Change, EarlyView.ABSTRACT Organizations experiencing hyper‐transformation—continuous, multidimensional, accelerated, and simultaneous organizational changes—face some limitations in traditional strategic agility and ambidexterity frameworks. Current strategic agility emphasizes rapid responsiveness but insufficiently addresses the nuanced management of varying speeds ...

Tooth contact analysis of spur gears. Part 2-Analysis of modified gears
MATEC Web of Conferences, 2017 The misalignment between gears axes or direction deviations of teeth leads accentuate the edge effect, Modified spur gears which localize the initial bearing contact by proper modifications of the lead profile are used to avoid the development of the ...

A Life Study of Ausforged, Standard Forged and Standard Machined AISI M-50 Spur Gears [PDF]
Tests were conducted at 350 K (170 F) with three groups of 8.9 cm (3.5 in.) pitch diameter spur gears made of vacuum induction melted (VIM) consumable-electrode vacuum-arc melted (VAR), AISI M-50 steel and one group of vacuum-arc remelted (VAR) AISI 9310

CSR disclosure and investment efficiency in MENA countries: The moderating role of CSR committee
Strategic Change, EarlyView.ABSTRACT Corporate social responsibility disclosure (CSRD) is often recognized as a transparency mechanism that allows companies to communicate their commitment to CSR. However, CSRD may also exacerbate agency conflicts. This study addresses these two contrasting perspectives by investigating the impact of CSRD on investment efficiency and exploring ...

Failure in Motion: A Framework for Capability Erosion and Institutional Dysfunction
Strategic Change, EarlyView.ABSTRACT Drawing on the literature on capability erosion and institutional dysfunction (ID), this study develops a conceptual framework that sheds new light on how the interaction between capability erosion and ID creates conditions for business failure across borders. By articulating two dimensions of heterogeneous capability and resource erosion (i.e.

Thermal elastohydrodynamic lubrication of spur gears [PDF]
An analysis and computer program called TELSGE were developed to predict the variations of dynamic load, surface temperature, and lubricant film thickness along the contacting path during the engagement of a pair of involute spur gears.
