Precise control is a challenge, especially in dynamic processes. This is why measuring bearing forces is of great interest to system operators.
Little space for additional measurement technology
According to the current state of the art, external force sensors can be used for this purpose. The biggest disadvantage of this technology is that the sensor technology must be taken into account in the design process of the system. While the lack of installation space is often a problem for new designs, it is almost always a problem for retrofits, which entails very complex design changes.
The ideal solution is a load monitoring technology that offers the same functionality as conventional force sensors without the need for additional installation space.
Our solution
The sensor bearing from HCP Sense meets precisely these requirements. As we use the electrical properties of the roller bearing itself, no external sensors are required. Only one electrical contact, one on the rotating and one on the stationary part of the system, is sufficient.
The basic functional principle
Each individual contact between a rolling element and the inner or outer ring can be regarded as a plate capacitor consisting of two metal surfaces (inner or outer ring and rolling element) and the lubricant between them, which acts as a dielectric. Depending on the load, a different lubricating film thickness and a different capacitor surface are formed due to the Hertzian pressure. These variables can be recorded with our measurement technology in the form of different electrical impedances and allow direct conclusions to be drawn about the bearing forces.
