Used helical gear in many engineering applications as rack and pinion. This paper shows a study of three types pinion, these used gear, the first type is single second double third herringbone gear. The research explained distribution stresses, strains, elastic deformation contact area between all Some important conclusions were presented for purpose to can be design such choose high-strength m...

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...

Helical gears are widely used in various mechanical transmissions. Thus, analysing gear contact stresses is crucial to improve the fatigue limit and life of gears. In this paper, stress helical analyzed by finite element simulation experimental verification. The effect coefficient friction on analysed, with given coefficients friction. following conclusions can be drawn through test. 1) increas...
