Torque Measuring Shafts

The classic torque measuring shaft, as often used in test benches, presents numerous challenges. It is usually mounted on bearings and often equipped with slip rings, which leads to increased wear and undesirable force shunting. In addition, mounted measuring shafts require a bearing block and elastic couplings on both sides, which makes test bench operation more complex and less efficient. The bearing noise is also particularly disruptive and can be problematic in sensitive test applications.

The bearingless torque measuring shaft from MANNER Sensortelemetrie offers a superior alternative here. By eliminating bearings and couplings, not only is the test bench design more compact and economical, but the measurement accuracy is also significantly improved.

1. High measurement accuracy: With a basic accuracy of better than 0.05%, the bearingless torque measuring shaft sets new standards that cannot be achieved with conventional shafts with bearings.
2. Compact test bench design: The elimination of bearing blocks and couplings allows for more compact designs.
3. Reliability at high speeds: The bearingless torque measuring shaft is designed for speeds of up to 150,000 rpm, minimizing the risks associated with shaft vibrations and coupling problems.

The MANNER torque measuring shaft is based on state-of-the-art sensor telemetry. The torque signal is recorded using strain gauges and digitized by a high-precision measuring amplifier mounted on the shaft. This operates with a resolution of 16 bits and enables contactless signal transmission via an antenna gap of up to 10 mm. This means that installation remains unproblematic both radially and axially.

The bearingless torque measuring shaft can be easily integrated into the shaft train. The connection is made using cost-effective Lenze clamping couplings or bellows couplings. In addition, the recorded torque data can be output analog or digitally via interfaces such as CAN, EtherCAT, Ethernet or USB.

The engineering experts at MANNER Sensortelemetrie are on hand to advise you on selecting and integrating the optimum torque measuring shaft. The company offers special bearingless torque transducers for test bench applications with a measuring range from 1 Nm to 1 kNm. These are characterized by extremely low inertia, high speed stability, and easy integration into existing systems.
