The torque sensor can be suspended in the drive system without bearings. When installing the suspension, the torque sensor can be placed between two half couplings, and only parallel misalignment adjustment is required, as the angular displacement can be adjusted through the sensor suspension. However, we do not recommend using two and a half couplings: when the torque sensor is located between the drive train and two flexible couplings, during rotation, the weight of the torque sensor can cause rope skipping vibration, which may have catastrophic consequences.
Flexible components located at both ends of the torque sensor are acceptable, but not recommended. Because torque sensors can cause sagging, it may cause critical speed issues. When installing and adjusting the rotor and stator, it is important to use suitable bolts. By consulting the torque sensor installation manual, you can find a chart that explains how to use bolts and tighten them.
When making flange connections, it is important to harden the adapter flange to Rockwell (RW) hardness, which is close to the torque sensor hardness. Most torque sensors have a hardness of RW 38-42, so the adapter flange needs to be hardened to the corresponding level. During the installation process of the stator and rotor, appropriate clearance should be maintained between them. The air gap between the two is 4mm, or 2mm on each side.
Tips:
1. Install the torque sensor as close as possible to the bearing seat, and install two double flexible couplings on one end of the torque sensor, usually on the load side of the sensor. Some torque sensor manufacturers provide integral connection components.
2. The recommended method is to use two flexible components on the load side of the sensor, with the drive end rigidly connected.
3. Use grade eight bolts or better bolts, and the tightening of the bolts is based on the range of the sensor.
