Analysis of spur gear teeth for static deflections
The problem of the deflection of spur gear teeth has been previously investigated analytically by several authors. Two of the papers dealing with this topic were written by Timoshenko and Baud (18)t and Marin and Shenk (11). Both papers employ the cantilever beam approach in which the spur gear …

The measurement of static deflections in spur gear teeth
The problem of measuring deflection of spur gear teeth has been considered by several investigators. Attia (11) in 1959 measured tooth deflections using an unbonded strain gage as an extensometer. The combined deflection of the gear tooth and the gear body was measured. More than one tooth-pair was …

Does public debt spur or hinder economic growth in Zambia?
This study investigates the relationship between public debts and economic growth in Zambia using ARDL analysis covering the period from 1970 to 2015. The results confirm the existence of the long run relationship between public debt and economic growth but the relationship is found to be negative …

A finite element analysis of pinion shaped spur gear teeth
… upon the geometry and root stresses in external spur gears using the finite element method is given. The models analyzed have the shape of a ring with three teeth. The middle tooth is loaded and load sharing has been assumed. Thirty-five finite element models were used for the computation of …

The determination of hob offset design values for nonstandard spur gears
It is easy for a designer to design a set of spur gears to operate properly at a standard center distance. But the problem is more complicated when a predetermined center distance is necessary that is not considered standard. When the gears are cut, the hob can he advanced into or withdrawn from …

A photoelastic study of stress distribution in a spur gear tooth
As pointed out in the “Discussion of Results”, the sub-surface stresses in a gear tooth decrease very rapidly with its depth. This result serves as a supporting evidence to the common practice of case-hardening the gear teeth. Previously this was done according to the mechanical properties of the …

Phase noise and spur reduction in an array of direct digital synthesizers
… in any real array, the broadband noise and spurious components will be correlated to some degree, limiting the gains achieved by parallelization. This thesis examines the potential performance benefits that may arise from using an array of DDSs, with a focus on several types of common DDS …

Stress concentrations in undercut spur gear teeth via the finite element method
An analysis of the influence of undercutting on the stress concentration factor for undercut gears using the finite element method is presented. The models used are in the shape of a whole gear with three teeth. The middle tooth is loaded assuming single-tooth contact. Thirty seven finite element …

A finite element study of bending stress variation in meshed spur gear pairs
… of the bending stresses in a pair of meshed spur gears using the finite element method is presented. The models analyzed were in the shape of a circular gear with five teeth or a five-tooth rack. A unit torque (1 lbf-ft) was applied as the form of nodal forces on the nodes around the bore …

Die Spur der Glasperlen. Akteure, Strukturen und Wandel im europäisch-ostafrikanischen Handel mit Glasperlen
… eingereichten Dissertation folgt Ulf Vierke der Spur der Glasperlen von ihren europäischen Produktionsorten im oberfränkischen Fichtelgebirge und im böhmischen Isergebirge bis hin zu den Maasai in Ostafrika. Eine Route, die die Glasperlen sogar – jetzt zu Souvenirs verarbeitet – wieder nach …

Maximum torque of combination threats for spur gear based on AGMA and JGMA standards
… types of tooth failures are known to happen to spur gears. There are tooth bending failure (breakage) and tooth surface pitting failure. The focus of this study however will be on the JGMA and AGMA standards of gearing. Different methods were used to gather relevant data from both standards. …

Fiber Orientation Prediction and Strength Evaluation of Composite Spur Gears Reinforced by Discontinuous Fiber
… To achieve proper power transmission in spur gears, fiber orientation can be made parallel to the flow direction in the skin layer by controlling injection molding process parameter like gate location, number of gates, injection pressure, injection temperature, cooling rate etc.</p>
