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.
