This work presents the possibilities of using the stress redistribution techniques by introducing the circular stress relieving features in the stressed zone to the advantage of reduction of root fillet stress in spur gear. The pinion spur gear is taken under examination and the parameter for comparison is principal stress measured by applying load on HPSTC [Highest Point of Single Tooth Contact]. A circular stress relieving feature is introduced on various locations and by doing so a considerable amount of reduction in principle stress was examined which resulted in long operating life of spur gear.

A program is developed for computer aided design of hydrodynamic journal bearing. This program is based on Raimondi and Boyd chart and tables, it is developed using an integrated methodology for designing of full (360°) hydrodynamic journal bearings. A database containing the design variables of load per unit of projected area and bearing clearance in industrial applications, needed in the bearing design is derived. The performance parameters including temperature rise, clearance, minimum film thickness and stability indicate how well the bearing is performing. The architecture of the software uses a rule based production system, so certain limitations on their values are imposed, using empirical guidelines, to assure satisfactory performance. Design optimization is based on maximum load and minimum friction.
