Single flank rolling test - analysing the rolling deviation
The single flank rolling test is a test method for measuring the rolling deviation on a bevel gear.
The aim of this method is to check the gearbox quality and recognise faulty gearboxes at an early stage.
Test principle
The measurement is carried out under quasi-static conditions in order to exclude dynamic effects.
For this purpose, high-resolution encoders are attached to the pinion and ring gear side.
For this purpose, high-resolution encoders are attached to the pinion and ring gear side.
The test takes place at:
low speeds up to 60 1/min and
loads up to 20 Nm
take place.
During the test, the two gear pairs are rolled against each other until each tooth has touched each tooth of the mating gear once.
In this way, any deviation in the transmission ratio due to geometric irregularities is precisely detected.
Data evaluation
The measured values are analysed in the time and spectral range.
The measurement results are averaged over one revolution to improve the informative value.

The evaluation in the time domain makes it possible to separate long-wave and short-wave components of the deviation.
This allows macro-geometric and micro-geometric errors of the gear pair to be visualised and evaluated separately.
