The metrology on the Höfler Cylindrical Gear Roll Testing Machine R 300 provides a reliable way to determine the root causes of gearbox noise. Due to the short measuring time, it can be easily integrated into any manufacturing process and enables 100 % quality control of the gears produced. The R 300 is designed for all roll testing processes that are relevant for evaluating the running behavior and noise behavior of gears. These include the single-flank test, the structure-borne noise test, and the torsional acceleration test. 

The double-flank test can also be performed if needed. Depending on its equipment, the R 300 enables testing of gears and shafts, a particularly important factor for components from an electric vehicle drivetrain system (eDrive). For testing the eDrive intermediate shaft, Klingelnberg will demonstrate a process for roll testing both gears on the shaft in one test cycle. This saves the time that would otherwise be required for a second loading and unloading and for re-tooling the machine, and reduces test costs.
