Learning to calculate spur or helical gears is a difficult task. Despite the vast amount of available literature, the non-graduate students make all kinds of mistakes when they start to study the matter. The group that presents this paper realized that the reasons for these errors is a misunderstanding of factors and the time spent on calculus to obtain the modified coefficients of allowable st...

Here the theoretical maximum contact stress is calculated by Hertz equation. Also the finite element analysis of spur gear is done to determine the maximum contact stress by ANSYS 14.5. It was found that the results from both Hertz equation and Finite Element Analysis are comparable. From the deformation pattern of steel and grey cast iron, it could be concluded that difference between the maxi...

This paper presents the study of induced currents and temperature distribution in gear heated by induction process using 2D finite element (FE) model. The model is developed by coupling Maxwell and heat transfer equations into a multi-physics model. The obtained results allow comparing the medium frequency (MF) and high frequency (HF) cases and the effect of machine parameters on the evolution ...

The computer program GearKURT has been created to calculate mechanical gears. allows you gears:
 - closed cylindrical spur gear
 helical open Novikov's bevel gear with indirect teeth
 worm-gear.
 a dialog interface written in the object-oriented programming language Delphi and compiled into an exe-file. choose necessary material method of heat treatment for manufacture gears...
