The contact stress and the bending stress of a set of helical gears with localized support contact, through finite element analysis (FEA). The proposed helical gear assembly comprises an involution pinion and a double crown gear. The mathematical models of complete cog geometry of the pinion and the gear have been derived based on the theory of the gear. Consequently, a mesh generation program was also developed for the analysis of finite element stresses. The distribution of gear voltages is investigated using the commercial FEA package, ABAQUS / Standard. In addition, several examples are presented to demonstrate the influences of the gear design parameters and the contact positions in the voltage distribution.
One of the best power transmission methods between the axles is gears. The gears are mainly used to transmit torque and angular velocity. The rapid development of industries such as vehicles, shipbuilding and aircraft require the advanced application of gear technology. Customers prefer cars with highly efficient engine. This needed a demand for power transmission rather. The automobile industry is one of the largest manufacturers of gears. Greater reliability and lighter weight gears are necessary to make the automobile light at weight as lighter cars are still in demand. Success in reducing engine noise promotes the production of quieter gear pairs for further noise reduction. The best way to reduce gear noise is by reducing vibration related to them.
