Reduction Gears with Inclined Planetary Gear and Arc Tooth Bevel Gear

TRANSACTIONS OF THE JAPAN SOCIETY OF MECHANICAL ENGINEERS Series C, 2006
We have designed new reduction gear, in which the arc tooth bevel gear is fixed on the inclined planetary gear. Making use of the shim, we can easily adjust the backlash of the reduction gear. Such basic characteristics as the noise, the torsion and the transmission efficiency of this system, with and without the backlash, are measured by changing the ...

National Policy Coherence Counts for Reducing Inequality in Global Climate and Development Agendas

Sustainable Development, EarlyView.
ABSTRACT International institutions promote policy coherence as crucial to the effective and fair implementation of global sustainability agendas, though the evidence for its benefits is slim. We present here the first systematic cross‐country dataset on the consequences of national government efforts to promote policy coherence for vulnerable groups ...

New Method for Isomorphism Identification of Planetary Gear Trains based on Traversing Loop

Jixie chuandong, 2020
Isomorphism identification is one of the indispensable processes in structure synthesis of planetary gear trains. It is of great significance for the creation of novel planetary gear train with excellent transmission characteristics.

Bridging Global Sustainability Objectives With Corporate Reporting Standards: Sustainable Development Goals Meet European Sustainability Reporting Standards

Sustainable Development, EarlyView.
ABSTRACT Given the complexity of the Sustainable Development Goals (SDGs), aligning corporate sustainability with them can be challenging. Drawing on systems thinking, this study examines how the European Sustainability Reporting Standards (ESRS) align with the SDGs and bridge macro‐level global goals with firm‐level metrics.

Joint Modeling of Planetary Gear Train and Bearings of Wind Turbines for Vibration Analysis of Planetary Bearing Outer Ring Looseness Fault

Energies
The planetary bearing looseness fault can cause the planetary gear train to fail. Conventional modeling methods do not consider complex component-coupling relationships for fault feature analysis.

Embedded Interactions and Selective Disclosure: Network Effects on Conversations aboard Skylab

Symbolic Interaction, EarlyView.
How do absent others influence our interactions? We argue in this paper that interactions are embedded within networks formed by chains of specific relationships between known third parties. The anticipation of future interactions with external others conditions our interpretation of the current situation and affects our behavior in the interaction. We

Efficiency analysis of planetary gears [PDF]

, 2018
By kinematic combinations of toothed pairs with external and internal contacts, we can obtain planetary gears with a considerably improved performance than the corresponding ones with fixed axes, as well as planetary gears with notably poor performance regarding the efficiency.

Den attendance by Arctic foxes experiencing 10 years of increasing tourism

Wildlife Biology, EarlyView.
Wildlife tourism is a growing industry, and an increasing number of people seek to observe and interact with wild animals in their natural surroundings. In Iceland, the native Arctic fox Vulpes lagopus is widespread and has been under heavy hunting pressure for centuries.
