Abstract:
A torque sensor bearing arrangement for a shaft having first and second bearings, each with respective inner ring and outer rings with rolling elements therebetween. The bearings are located at first and second ends of the shaft. First and second sensing rings are connected to the outer rings of the bearings. First and second marking rings are connected to the inner rings, spaced apart from and aligned with the respective first and second sensing rings. The marking rings each have a wavy surface facing the respective sensing ring to form respective first and second sensors from the respective sensing ring—marking ring pairs. The sensors detect a rotational angle position of the shaft and provide a signal. A controller receives signals from the first and second sensors and calculates at least one of torque or an angular speed of the shaft based on signals from the first and second sensors.
