Abstract
A device for determining a bearing preload of a rolling-element bearing includes an exciter configured to be attachable to a component of the rolling-element bearing and to excite the component of the rolling-element bearing and cause it to vibrate when the rolling-element bearing is not rotating, at least one vibration sensor configured to be attachable to the component or to a further component of the rolling-element bearing and to record (capture) a mechanical reaction, in response to the excitation, of the component or the further component of the rolling-element bearing, and an evaluating circuit configured to receive the sensor signal and provide an evaluation signal based on the sensor signal, the evaluation signal including information about the bearing preload. An associated method and computer program are also disclosed.
