The Mathematical Model of Spiral Bevel Gears - A Review

The spiral bevel gear (SBG), with its high contact ratio, high strength and smooth driving, is widely used to transmit dynamic power in various mechanical products, including vehicles, mining machinery, aerospace engineering, and helicopters [1] to [4]. Typical SBGs are shown in Figs. 1a and b. The SBG has been a subject of research for almost a century, and there is a significant amount of lit...

Modeling the Infrared Intensity of a Large Commerical Aircraft Thesis

Measuring the infrared signature of large civilian aircraft has become increasingly important due to the proliferation of man-portable air defense systems (MANPADS) and the increasing threat of their use by terrorists. Because of the range of these shoulderfired weapons, most aircraft flying over 20,000 feet are safe from the threat; however, aircraft taking-off or landing are extremely vulnera...

Geometry Definition and Contact Analysis of Spherical Involute Straight Bevel Gears

A practical application of the spherical involute surface to the forged straight bevel gears is provided and demonstrated in this work. Conjugate (pure involute) theoretical surfaces are developed from the input design parameters. The surfaces are modified to suit the actual application (automotive differential). The unloaded (or low load) tooth contact analysis of modified surfaces is performe...

Empirical Modelling of Mrr in Electrochemical- Mechanical Finishing of Bevel Gears

This paper presents the micro-finishing of bevel gears by electrochemical-mechanical finishing (ECMF) process under different experimental conditions of current, rotating speed of workpiece and electrolyte concentration. These different experimental conditions are planned on the basis of box behnken design (BBD) design of experiments (DOE) technique of response surface methodology (RSM). An emp...
