R 300

HÖFLER Cylindrical Gear Roll Testing Machine

Compact, flexible and highly accurate testing technology

The Höfler Roll Testing Machine R 300 is covering the same component spectrum as the Speed Viper series in terms of axis traversing paths. Wheel components can be tested up to an outside diameter of 300 mm. In conjunction with the optional counter support, shafts up to 800 mm long in extreme cases can be analyzed to determine their running performance and noise behavior.

Flexible Setting Options for Test Parameters

  • Center distance for single flank test can be set in line with as-installed position in the transmission
  • Variable test force setting in double-flank and helix test for maximum sensitivity thanks to linear drive technology 
  • Workpiece speed up to 3,000 rpm for fast test times and optimal excitation of the structure-borne noise and angular acceleration sensors
  • Counter support with variable clamping force setting, particularly for slim shafts
  • Double-flank test duration minimized through master gear compensation

User-Friendly Operating Concept

  • Safe basic operation through hardware switches, e.g., workpiece clamping/releasing, manual traversing of test slides, etc.
  • Innovative touchscreen technology with intuitive graphical user interface
  • Clear operator guidance thanks to process-oriented menu structure
  • Menu navigation is ultra-easy and requires minimal training thanks to process-based HMI structure
  • Production dashboard provides an at-a-glance display of the most important test results for a selectable time window

Maximum Precision and Accuracy

  • High-precision angular measurement systems and 12.4 GHz scan rate for maximum-accuracy measured data acquisition in the single flank test
  • Highly sensitive acceleration sensors and 50 kHz scan rate for high-resolution structure-borne noise and angular acceleration measurement
  • High-precision Heidenhain linear scales for maximum-accuracy measured data acquisition in the helix and double-flank test
  • High-precision linear guides to ensure high mechanical accuracy and reproducibility
