The paper talks about the migration phenomenon that is observed in gears. The phenomenon discussed here is that observed on hypoid gears which due to their high spiral angles cause the issue to be more sensitive, but the analogy to other gears is applicable. Mahindra manufactures hypoid gear sets for its axles in-house that go on a wide range of its products; with performance benefits also come the stringent quality requirements for hypoid gear sets. Migration is the phenomenon that causes the furling or unfurling of individual gear teeth with respect to each other. This in effect causes the circular tooth spacing between two teeth to become non-uniform. This has a direct effect on the performance of the mated gear set.

The paper talks about machining techniques and solution approaches while machining Aluminium grade gearbox housings. Mahindra’s next generation gearbox housings are made totally of Aluminium; along with the higher strength to weight ratio that comes with using Aluminium come highly optimized ribbed structures that aid in achieving the said strength. While machining such Aluminium structures, it is imperative that the clamping forces do not load the component in ways it is not intended to. The paper talks about finish machining and proving out a semi-finished gearbox housing set (front, intermediate plate and rear) on a conventional Horizontal Machining Center (HMC). The input to the machine is the semi-finish housing that is already machined before with stock for finish operations.
