Measuring the friction torque in greased ball bearings

  • Torque measurement < 0.1 Nm
  • Speed measurement up to 20000 1/min
  • Includes built-in USB port
  • High measurement cycle rates
  • Visualization and data logging in one measurement step

Task

Das Reibmoment an gefetteten Kugellagern soll erfasst werden. The torque is applied using a variable-speed controlled asynchronous AC motor. Depending on the amount of grease in the ball bearing, the motor is run at different speed levels for various time intervals in order to obtain continuous measurements of the friction torque.

Specific Requirement

Protokollierung der Messdaten über die integrierte USB-Schnittstelle. 

Solution

Das Reibmoment wird im Dauerlauf kontinuierlich vom Drehmomentsensor Typ 8661 erfasst und via USB-Schnittstelle an die PC-Software DigiVision zur Visualisierung und Protokollierung übergeben.
