Research on the Hobbing Processing Method of Marine Beveloid Gear [PDF]

Machines
Due to the particular structure of the beveloid gear, it cannot be directly hobbed by an ordinary gear hobbing machine. The existing processing method is complex and has a high cost.

Towards circular economy: A guiding framework for circular supply chain implementation

Business Strategy and the Environment, Volume 32, Issue 6, Page 2684-2701, September 2023., 2023
Abstract Closing the loop for resource efficiency is a well‐known practice in the industry. To concretize the circular economy implementation strategies, closed‐loop thinking requires innovation and adaptation. Circular supply chains (CSCs) are one of the key enablers in closing the loop by design or intention for value recovery and profit maximization.

In‐process evaluation of continuous generating gear grinding for maintaining workpiece quality and acoustic behavior of gear wheels

Engineering Reports, Volume 4, Issue 7-8, July-August 2022., 2022
Continuous generating gear grinding of gear wheels underlies high economic, acoustic‐ and quality‐requirements, especially in electric mobility solutions. With an intelligent acquisition and processing of in‐process signals, an appropriate adaption of manufacturing parameters is possible in order to react to changes in the process and environmental ...

Fetal growth, birth size and energetic cost of gestation in southern right whales

The Journal of Physiology, Volume 600, Issue 9, Page 2245-2266, 1 May 2022., 2022
Abstract figure legend The aim of this study was to estimate the energetic cost of gestation in southern right whales. First, drone photogrammetry was used to measure the size of newborn southern right whale calves on their breeding grounds. Birth lengths were found to be ∼35% of maternal lengths.
