摘要

Gear strength calculation must be done in an appropriate and productive way to develop a strong and compact movement transmissions systems efficiently. In this research, the advantages and disadvantages of the calculation methods and the results of the calculation on a sample application are compared by referencing DIN 3991 method solution. Manual solution is an impractical and error-prone method. A max 27.5 % difference was found between ISO and AGMA analytical results. There is also a 17.3 % difference between KISSsoft solutions of the same methods. The KISSsoft solution gives immediate results in the event of changing different modules and revolutions. Modeling and mesh studies are required in ANSYS solution. Mesh affects the Ansys solution directly. There is 7 % difference between the Ansys FEM and KISSsoft (DIN) solutions. However, ANSYS enables the calculation in non-standard gears and modified gears. In this study, current gear calculation methods are presented, compared and evaluated in detail on an application.
