Angular Velocity

Gears are used for transmission of angular motion and torque from one shaft to another. They are required to deliver different angular velocities (Speed) and torque to meet the demands of many engineering applications. Gears are generated employing either cycloidal or involutes profile for the tooth. Among these, involutes profile is more commonly used tooth-profile for the gears because of simplicity in tooling and manufacture, they are less sensitive to small changes in center distance and tooth profile can be shifted along any part of the involute conveniently. The process of shifting the profile along the involute curve is also known as profile correction or profile modification. Method of providing profile shift. Contact stress between the gear teeth in mesh determines the ability of the gear to transmit the power safely. In improving the contact strength of gear teeth, profile shift is found to be the best option beyond the use of high strength materials and surface treatment techniques. This paper discusses an alternate yet simple method of improving contact strength by the way of altering the tooth-sum.
