PARAMETRIC DESIGN AND OPTIMIZATION OF A STANDARD SPUR GEAR WITH CIRCULAR FILLET USING FINITE ELEMENT METHOD

Gears are toothed cylindrical wheels used for transmittal mechanical power from one rotating shaft to a different and is one of the foremost important parts in a mechanical power gear. Due to their high degree of compactness and reliability it's expected that gears can predominate because the best suggests that of power transmission in close to future. Increase in demand for accurate and quiet power transmission in machines, generators and vehicles has resulted in the need for a lot of precise analysis of drugs characteristics. In auto business as lighter vehicles continue to be in demand, highly reliable and light-weight weight gears became necessary. Designing extremely loaded spur gears for power transmission systems that are each robust and quiet, requires analysis ways that will simply be enforced and conjointly give info on contact and bending stresses, along with transmission errors. Transmission error results due to two main factors i.e. manufacturing quality or mounting errors and elastic deflection underneath load. Hence, compensation for transmission errors by modifying gear teeth needs to be thought-about by gear designers. Transmission error is considered to be one the most contributors to noise and vibration in a gear set. If a pinion and gear have ideal involute profiles running with no loading torque they must in theory run with zero transmission error
