Abstract

After repeated complaints from customers about failure, the crown and pinion assembly of the vehicle was analyzed by standard metallurgical methods. Standard material composition of the part was confirmed by chemical analysis. Tooth contact analysis was done to understand the contact and sequence of failure. Micro hardness test was done to understand about the hardness of the specimen. The nature of fracture is studied by subjecting the specimen to micro-structural study. It was found that the effect of combination of low case hardness and improper composition was augmented by improper alignment while assembling caused premature failure of the component.
