Abstract:
Spur gears are widely used transmission components. In the traditional design process, the noninvolute part of the tooth profile curve is difficult to describe with mathematical equations. This article puts forward a new parametric modeling method, which can describe the modified involute part of spur gears and parameterize and optimize the transition part of the involute curve of the spur gear. And this model of the spur gear can be created by parameters which is input in Scilab software and the spur gear graphic can be completed correspondingly.

Abstract:
Gear is the one of the important machine element in the mechanical power transmission system. Spur gear is most basic gear used to transmit power between parallel shafts. Spur gear generally fails by bending failure or contact failure. This paper deals with the bending stress calculation of spur gear theoretically and validating it with ANSYS software. These meshed gears from the gear box are subjected to considerable damage throughout its life span due to dynamic excitations caused by terrain undulations, the rotating wheel and track assemblies.

Abstract:
In gear applications, the initiation of cracks at or near the contact surfaces of gear mates occurs mostly due to the surface contact mode of gear failure. This study aims to investigate the influence of gear materials on the contact strength of spur gears. In this study, four different gear materials are selected and the contact stress on spur gear mates is analyzed. Hertz’s contact stress equation and ANSYS 16 are used for the theoretical analysis and finite element (FE) method, respectively. The results of Hertz’s equation are compared with the results of ANSYS 16. The results show that the

Spur gear contacts experience a number of time-varying contact parameters including the load, surface velocities, radii of curvature, and slide-to-roll ratio.

A full transient EHL solution of involute spur gear under impact load is obtained by utilizing the multigrid technique.

Because gears are one of the most important design elements, failure of one gear can have a significant impact on the entire drive system, which can be caused by stress, contact pressures, or temperature.

The gears in a transmission are lubricated to prevent their premature failure as a result of pitting and wear on the tooth surfaces. Furthermore, the lubricant also limits the rise in surface temperature of the gears, which could otherwise lead to failure as a result of scuffing.

Abstract:
The load distribution across the contact line(s) of spur gears is essential for the gear designer to be able to accurately stress gears for a given application. Existing gear standards (eg BS 436, AGMA 218 DIN 3990) use a thin slice (2D) model of the meshing gear teeth to estimate the contact line load distribution. This approach clearly fails to model properly teeth subjected to mal-distributed loads, since the buttressing effect of adjacent tooth sections tends to flatten the load distribution.

Abstract:
Denna rapport ger en kunskapsgrund om de praktiska förutsättningarna, kravbild, och forskningsläge för utformning av underhållsområden på större driftplatser. Rapporten inleds med en bakgrund och motivering till behovet av underhållsområden, samt en beskrivning av hur studien har genomförts. En genomgång av förutsättningar och begränsningar visar bland annat att de tekniska delsystemen (spår-, signal-, och elkraftsystem) måste beaktas eftersom de har olika sektionering, gränspunkter och skyddsgivning för de arbeten som behöver utföras, samt att trafikeringsbehoven och dess variation behöver be
