Single Flank Testing 1. The quality of a power train – and thus that of a gearbox – s more and more dependent on the noise emitted by the package. Hence testing methods such as noise or single flank testing gain in importance. 2. Biggest advantage of this testing method is its numerical comparability throughout the world, as all results are non-dependent on any external factors. 3. ROTEC system can also acquire and calculate values such as angular acceleration of gear and pinion, structure-borne noise of the bearings or the emitted airborne sound. 4. DIN Characteristic Values : F'i total error. f'l long wave component, f'k short wave component, f'max maximum value of tooth-to-tooth error, f'mit average value of tooth-to-tooth error
