Effect on strength of Involute spur gear tooth by considering Uncertainties in Geometry and Material propertiesby using Finite Element Methods-A Review

Gearing is the special division of Mechanical Engineering concerned with the transmission of power and motion between the rotating shafts. Gears not only transmit motion and enormous power satisfactorily, but can do so with very uniform motion. It is the best and the economical means of achieving this transmission. Gear teeth fail due to the static and the dynamic loads acting over it. This paper presents study of effect of various parameters on beam strength of involute spur gear tooth. The effect on strength of involute spur gear tooth is studied by considering uncertainties in geometric parameters like fillet radius, face width etc. Also the uncertainties in material properties which affect strength of involute spur gear tooth are studied
