The study employed the finite element method to develop a validated theoretical model to investigate the distribution of thermal hoop stress around the teeth of a spur gear operating in a filler machine. Three cases of temperature distribution along the radius of a gear tooth were assumed and investigated. The outcome showed that the maximum effective stress occurs at the tip of the gear tooth ...

The paper describes a simulation method to predict efficiently and accurately how changes to a transmission’s housing affect gear mesh misalignments. Two key elements of this analysis are described. A fully coupled non-linear algorithm to analyse the shaft/bearing/gear/housing hyperstatic system has been developed to analyze the non-linear components. Using MSC.Nastran, a reduced stiffness matr...

A dynamic model of multiple-stage planetary gear train composed of a two-stage planetary gear train and a one-stage parallel axis gear is proposed to be used in wind driven generator to analyze the influence of revolution speed and mesh error on dynamic load sharing characteristic based on the lumped parameter theory. Dynamic equation of the model is solved using numerical method to analyze the...

Research on damage of gears and gear pairs using vibration signals remains very attractive, because vibration signals from a gear pair are complex in nature and not easy to interpret. Predicting gear pair defects by analyzing changes in vibration signal of gears pairs in operation is a very reliable method. Therefore, a suitable vibration signal processing technique is necessary to extract defe...

The International Organization for Standardization (ISO) provides a method by which different spur and helical gear designs can be compared in terms of the risk for surface fatigue. The calculation of surface durability is based on Hertzian contact theory modified by factors for making adjustments peculiar to gearing. These factors are mainly determined through experimentation, and include surf...
