Tests on Scoring Resistanceof Through Hardened Gears
按齿轮胶合承载能力试验方法(GB/T13672—92)对40CrNi2Mo中硬台面齿轮进行了胶合承载能力试验,试验测定该种齿轮的抗胶合承载能力失效载荷级为6级。铁谱分析很好地反映了胶合发生时抽样中磨粒的变化情况。

IMF Conditionality on Corruption: The Politics of Good Governance
ABSTRACT We offer a systematic analysis of IMF loan conditionality on corruption and argue that the Fund's pursuit of anti‐corruption measures is tempered by two political costs. First, because corruption is politically sensitive, the IMF risks destabilizing recipient governments and provoking crises.

Selection of effective hardened case depth of gears based on the tooth failure mode
ObjectiveThe depth of the hardened layer of gears is a significant factor influencing on strength and load-carrying capacity of gears. Modern research shows that different failure modes of gears require different effective hardened case depths.

Output Quality, Productivity, and Demand: Evidence from the Chinese Steel Industry
ABSTRACT Unobserved objective output quality complicates the analysis of firm productivity and demand because higher‐quality products entail higher costs but offer greater consumption benefits. Using a panel of firms with output quality data, we decompose quantity‐based productivity into fundamental productivity and the costs of quality, and separate ...

On the Mutual Relation Between Contact Ratio and Crack Propagation in the Tooth Root of Spur Gears
ABSTRACT This work investigates the mutual relationship between contact ratio and tooth root crack propagation in spur gears, with particular focus on the influence of meshing stiffness and load sharing on the tooth root lifetime. An experimental case study originally reported by Rettig, in which SN curves of gears with similar geometry but different ...

Increasing the wear resistance of gears during laser hardening [PDF]
The paper presents the main results of metallographic studies and tribotechnical tests of steel for the production of 25CrMnTi gears. Quenching of the samples was performed using a defocused and oscillating beam normal to the processing speed vector ...

The Manifold Impacts of Management Research
Abstract Management scholarship's apparent lack of impact is a misconception based on the presumption that impact involves a direct and visible influence of papers or research projects on management practice. Theory‐building impacts management practice in diverse, sometimes indirect and unnoticed, manifold ways.

‘I'm Dead!’: Action, Homicide and Denied Catharsis in Early Modern Spanish Drama
Abstract In early modern Spanish drama, the expression ‘¡Muerto soy!’ (‘I'm dead!’) is commonly used to indicate a literal death or to figuratively express a character's extreme fear or passion. Recent studies, even one collection published under the title of ‘¡Muerto soy!’, have paid scant attention to the phrase in context, a serious omission when ...

Surface reconditioning through mechanical and electrochemical polishing is shown to extend the fatigue life of predamaged 42CrMo4 steel by over 12 times. By removing ≈100 μm of surface material, surface‐driven fatigue damage is mitigated. This study introduces a reuse potential metric to evaluate fatigue recovery and support sustainable steel reuse.
