Figure: Single flank test

Single flank test

The single flank test is a test method that is used to measure the rolling deviation on a bevel gear. The aim is to check the quality of the gearing and to detect faulty gearing. The measurement itself takes place under quasi-static conditions and is intended to exclude dynamic effects. High-resolution encoders are attached to the pinion and ring gear sides and tested at low speeds of up to 60 rpm and loads of up to 20 Nm. The two pairs of gears are rolled off each other until each tooth is in contact with each tooth of the mating gear. In this way, any deviation in the transmission ratio based on geometric deviations is recorded. The evaluation of the measured values is carried out in the time and spectral range. The measurement results are averaged over one revolution. The evaluation in the time domain can separate long-wave and short-wave components. Thus, macro- and microgeometric errors of the gear pair can be displayed separately.
