AGMA 10FTM05

The current AGMA standards provide a lot of information aboutthe calculations of loose gears and gearbox components – shafts,splines, keys, etc. These recommendations are based mostly on the”traditional” methods of mechanical engineering, found in manyclassical textbooks and research papers. Their accuracy andreliability have been proven in many years of gearbox design andfield tests. They are clear, concise, in most cases easy to programand apply even by a small gear company with limited resources.However new methods for calculations of mechanical engineeringcomponents like FEA (finite element analysis) are becoming widespread. Once these techniques were used only by big companiesbecause of their complexity and price but with the development ofthe computer technology they become more and more accessible tosmall gear companies which are the majority of participants in themarket. Nowadays, in the gear business, even a small gear companyis usually in possession of a modern CAD system which alwaysincludes a basic or advanced FEA package. Such CAD systems are mostoften run by one gear engineer who makes 3D models, engineeringcalculations and production drawings. The level of the FEA packagesis such that it allows the gear engineer to be able to docomponents calculations without deep knowledge in the FEA itself.So the question about the effectiveness of the traditional AGMAcalculations and the new FEA methods becomes of vital importanceparticularly for small firms.
