Abstract: A sensor bearing assembly having a rolling element bearing and at least one sensor is provided. The rolling element bearing includes an inner ring, an outer ring, and rolling elements arranged between the inner ring and the outer ring. The at least one sensor is arranged to convert one or more physical magnitudes to electrical sensor signals. The sensor is attached directly or indirectly to the rolling element bearing. The assembly further comprises a converter unit. The converter unit is arranged to convert the electrical sensor signals to output signals, the output signals are different to in type, form and/or amplitude in relation to the electrical sensor signals. The converter unit is also disposed in a separate enclosure that does not share the same enclosure with the sensor.

Abstract: An annular ring used as either the outer race or the bearing race in a roller includes at least one annular recess in which is disposed an annular reinforcement body. The reinforcement body subjects the region of the annular ring radially inside the reinforcement body to mechanical stresses. The side of the reinforcement body oriented toward this region is materially joined or bonded to the ring. The annular reinforcement body preferably possesses an internal radius that is smaller than the internal radius of the recess and the reinforcement body press-fitted into the recess. According to one embodiment, the reinforcement body is poured in liquid form into the recess. The shrinkage of the reinforcement body that occurs during the cooling phase after solidification produces stresses as well.

Abstract: Method for measuring the output torque of an asynchronous motor having a stator and a rotor comprising the steps of measuring the rotational frequency of the stator field of the motor, the rotational speed of the rotor, calculating a measurement value for the slip speed from the difference between the rotational speed of the rotor and rotational frequency of the stator field, and calculating a measurement value for the output torque form the slip speed and statistical performance characteristic values for the output torque intrinsic to the motor.
