A basis for the analysis of surface geometry of spiral bevel gears [PDF]

, 1983
Geometrical procedures helpful in the fundamental studies of the surface geometry of spiral bevel gears are summarized. These procedures are based upon: (1) fundamental gear geometry and kinematics as exposited by Buckingham, et al; (2) formulas ...

Sustainability Controls as Technologies of Actorhood: Constructing the Responsible Supplier in Global Supply Chains Le contrôle de la durabilité comme technologie d'actorialité : façonner le fournisseur responsable dans les chaînes d'approvisionnement mondiales

Contemporary Accounting Research, EarlyView.
ABSTRACT This paper examines how accounting and control practices constitute and distribute agency and responsibility for sustainability in global supply chains. Drawing on a field study in the fashion industry, we describe the sustainability control practices used by a major buyer firm vis‐à‐vis its suppliers and trace their evolution from a ...

Measuring Geometrical Parameters of Involute Spur Gears to Sub-pixel Resolution [PDF]

Procedings of the British Machine Vision Conference 1992, 1992
The problem of accurate determination of the position, orientation and width of involute spur gear teeth using a single front-lit image is addressed. The information is used to compute global measures of tooth concentricity and pitch variations across a gear wheel.

Worldwide Invasions of Centrarchidae: The Dark Side of the Sunfish Family

Fish and Fisheries, EarlyView.
ABSTRACT Freshwater fish invasions are major drivers of global ecological change, disrupting native biodiversity and ecosystem functions. However, many invasive fish hold significant socioeconomic value, resulting in conflict over their management. Centrarchidae, which are globally distributed and are important for sportfishing and aquaculture, are now

渐开线内齿轮副相对滑动率的研究

Jixie chuandong, 2001
The relative sliding ratio formulas of an involute internal spur gear pair are developed. The influences of teeth number （transmission ratio）, module, addendum modification coefficient, center distance and so on are analyzed on the relative sliding ratio

Experimental Study of Linear Profile Modification in Spur Gear Leg

International Journal of Technology
Gears with the involute profile are assumed to be rigid and good at producing mating gear. They are also deformable and deflectable, indicating additional space is required to avoid interference from the unpredictable shaft, misalignment, and dynamic ...

Post‐Release Mortality of European Bass (Dicentrarchus labrax) Discarded From Small‐Scale Estuarine Fishing

Fisheries Management and Ecology, EarlyView.
ABSTRACT Estuaries provide essential habitats for many fish species, but their confined and accessible nature may increase fish vulnerability to capture, and few empirical studies have quantified the value of restricting net fisheries in such areas.

Modeling of the kinematic geometry of spur gears using matlab

MATEC Web of Conferences, 2018
The analytical method of gear design is calculation-intensive and it is usually difficult to achieve optimum backlash and interference-free involute profile that are required to generate geometrical compatibility in a pair of meshing gears when design ...

渐开线圆柱齿轮副侧隙的几何模型及公式

Jixie chuandong, 2014
From the definition of backlash,the geometric elements of normal backlash and circumferential backlash are given by analyzing the meshing process of a pair of external involute cylindrical spur gears in geometrical method.In further,the formula of normal
