Abstract
Computer technology has touched all areas of today’s life, impacting how we obtain railway tickets, shop online
and receive medical advice from remote location. Computer-based design analysis is nowadays a common
activity in most development projects. Traditionally, the design field has been identified with particular end
products, e.g., mechanical design, electrical design, ship design. In these fields, design work is largely based on
specific techniques to foster certain product characteristics and principles The scope of this work includes, to
design, to model the bevel gear, to select gear materials , to detailed factor safety in design and to analysis
bevel gears. Gears are toothed elements that transmit rotary motion from one shaft to another. Gears are
generally rugged and durable and their power transmission efficiency is as high as 98%. Gears are usually more
costly than chains and belts. Bevel gears are gears where the axes of the two shafts intersect and the toothbearing faces of the gears themselves are conically shaped. Bevel gears are most often mounted on shafts that
are 90 degrees apart, but can be designed to work at other angles as well. The pitch surface of bevel gears is a
cone. Two bevel gears in mesh is known as bevel gearing. In bevel gearing, the pitch cone angles of the pinion
and gear are to be determined from the shaft angle, i.e., the angle between the intersecting shafts. The bevel
gear has many diverse applications such as locomotives, marine applications, automobiles, printing presses,
cooling towers, power plants, steel plants, railway track inspection machines, etc.
