Study on multi-degree-of-freedom near-net-shape forming method for aviation spur gears

Jixie chuandong
ObjectiveTo meet the high-quality and high-efficiency manufacturing requirements of spur gears for aviation equipment, conventional single-degree-of-freedom forming processes such as die forging and extrusion suffer from insufficient tooth profile ...

Gear Tooth Stress of an End-Relieved Spur Gear

Bulletin of JSME, 1966
In the nose-suspended type traction gears, the angle between the projected lines of axes of pinion and gear on pitch plane often becomes equal to about 10' and end tooth bearing happens, leading to tooth failures. In JNR, as the countermeasure for these failures, heavily crowned gears are used for nose-suspended type traction gears.

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 ...

Influence on micro-geometry and surface characteristics of laser powder bed fusion built 17-4 PH miniature spur gears in laser shock peening

Advances in Industrial and Manufacturing Engineering
Micro-geometrical errors, surface roughness, and surface integrity (microstructure, residual stresses, microhardness) play an important role in defining the quality of the gears as they directly affect their noise, vibration characteristics and service ...

Simulation of Rotational Vibration of Spur Gears

Bulletin of JSME, 1983
This paper introduces a developed simulator on a rotational vibration and a strain at a root of a tooth, on a power transmission spur gear. The simulator solves a differential equation with one degree of freedom in consideration of the behaviour of the stiffness around tooth tip meshing.

Energy Options to Reduce Deforestation Using EKC Model: A Region‐Based Longitudinal Approach

Land Degradation &Development, EarlyView.
ABSTRACT Forests are carbon storage that can reduce carbon emissions, so deforestation (decrease in forest area) is a serious threat to environmental sustainability. Indonesia is a large carbon sink due to its large forests. However, deforestation is quite high due to economic activities that use fossil energy.

修形直齿轮的啮合干涉与啮合间隙

Jixie chuandong, 2005
Errors of modified spur gears results in meshing interference or meshing clearance at the position of mating teeth coming into or out of contact. Based on the analysis of the relation among tooth deformation, normal profile modification and manufacturing

Intermittent gear rattle due to interactions between forcing and manufacturing errors [PDF]

, 2008
The interaction between eccentricity and an external forcing fluctuation in gear rattle response is investigated experimentally. The experimental rig consists of a 1:1 ratio steel spur gear pair, the input gear being controlled in displacement and the ...

An extinction‐emergency metacollection: Maximising future recovery options for Rhodomyrtus psidioides (Myrtaceae), threatened by Myrtle Rust

PLANTS, PEOPLE, PLANET, EarlyView.
A challenge for wild plant conservation is the rising incidence of plant pathogens that are difficult to interdict, contain and manage. Invasive, fast‐moving, broad‐spectrum pathogens impose societal costs through losses of intrinsically valuable wild biodiversity, ecosystem function, current and potential genetic and biological assets, culturally ...
