Abstract
The Complete study of Literature and reporting on how Spur gears are designed using steel-steel alloys and dynamic load is calculated for the spur gears. The analytical model is developed to simulate the load sharing characteristics through a mesh cycle. The model takes into account the main internal factors of dynamic load as time-varying mesh stiffness and composite tooth profile errors. Comparative different types of dynamic load processors study are included, which shows the different processors of the dynamic load. Pro E is an interactive CAD/CAM system, a fully 3-D double precession system that allows accurate description of almost any geometric shape. Pro E modeling provides capabilities to help the design engineer to perform conceptual and detailed deigns. It is a feature and constrained based solid modeler that allows users to create and edit complex solid models interactively. MSC Nastran is a powerful general purpose, Finite element analysis solution for small to complex assemblies. A standard tool, in the field of structural analysis for over four decades, Nastran provides a wide range of analysis capabilities including linear, static's, dynamic, displacement, strain, stress, vibration, heat transfer and more. Nastran can handle any material type from plastic and metal to composites and hyper elastic materials.
Highlights
Any toothed member designed to transmit motion to another one, or received motion from it, by means of successively engaging tooth is called a gear
Gears are of several categories and can be combined in a multitude of ways, some of which are meshing circular spur gears, rack and pinion spur gears, and worm gears

Summary
Any toothed member designed to transmit motion to another one, or received motion from it, by means of successively engaging tooth is called a (toothed) gear. Gears are a means of changing the rate of rotation of a machinery shaft. They can change the direction of the axis of rotation and can change rotary motion to linear motion. Helical and herringbone gears utilize curved teeth for efficient, high-capacity power transmission. Driven by worms transmit motion between non-intersecting rightangle axes. Gears mate or mesh via teeth with a very specific geometry. Gears are used for two basic purposes; increase or decrease of rotation speed and increase or decrease of power or torque. To increase speed and reduce torque a large drive gear is coupled to a smaller driven gear
