Development of a user friendly interface software for design and analysis of paralel axes external gears including quasi-static transmission error calculations

Gears are one of the most important power transmission elements required to transmit both torque and motion between shafts. The design or analyze of these very crucial elements of power transmission systems require too much time because of huge numbers of the parameters affect the gear static and dynamic performance. Gear design or analysis requires a good knowledge and engineering sense supported by the standards submitted by ISO (International Organization for Standardization), AGMA (The American Gear Manufacturers Association), DIN (The German Institute for Standardization) and some formulas such as Lewis Bending Equation. Even by using these international standards, designing a gear set, an engineer must carry out an iterative process because every geometrical or material property change of the gear influences most other parameters. Checking these influences by manual calculation is slow and prone to errors. These all increase the demand for software of designing gears, calculating parameters, redesigning (if required), determining geometry, size and material properties with high accuracy and minimum error in short time. In the scope of this thesis, a user friendly interface for gear design and analysis of parallel axes gears based on ISO, AGMA and DIN has been developed.
