Schaeffler at Hannover Messe 2022, hall 6, booth C48 Sensor-Based Precision Strain Wave Gears – Considerable Potential for the Cobot Market

Pressrelease Stage Image
New precision strain wave gear from Schaeffler with integrated torque sensor system

2022-04-06 | Schweinfurt

  • Integrated torque sensor technology – requires no additional installation space
  • Overall system rigidity remains unaffected by the sensor system
  • Inexpensive alternative to 6-axis force torque sensors

Schaeffler RT precision strain wave gears have been developed for demanding and particularly dynamic applications featuring a high level of torque. The precision strain wave gears are now available with the added option of a fully integrated torque sensor system, which delivers high-precision torque signals without the need for additional installation space or any resulting loss of rigidity in the overall mechanical system. A durable sensor solution suitable for volume application has been unavailable in the market to date – a gap which Schaeffler has now succeeded in closing with its sensor-based precision strain wave gears. Unlike other solutions available on the market, the torque sensor structure in sensor-based strain wave gears is applied to the flexspline on a permanent basis using thin-layer technology. The sensor system not only supports safety functions but also provides precise, sensitive position and process control. The torque signals can also be used in the development of an active vibration compensation system, with the aim of achieving shorter transient response times for highly dynamic motion profiles.
