Abstract

A vibrating machine is provided that includes a condition-monitoring device that has a first vibrating body supported flexibly in relation to a second vibrating body or a base, a first exciter that produces a targeted vibration behavior of the vibrating machine or the vibrating body. The condition-monitoring device has at least one first micro-electro-mechanical device in the form of an inertial sensor with at least three acceleration sensors and at least three yaw-rate sensors.

Claims

1. A vibrating machine with a condition-monitoring device, the vibrating machine comprising:

a first vibrating body supported elastically with respect to a second vibrating body or a base;

a first exciter that produces a targeted vibration behavior of the vibrating machine or vibrating body; and

at least one first microelectromechanical device provided in the condition-monitoring device, the at least one first microelectromechanical device being an inertial sensor having at least three acceleration sensors and at least three yaw-rate sensors.

2. The vibrating machine according to claim 1, wherein the inertial sensor comprising a data memory and/or processor.

3. The vibrating machine according to claim 1, further comprising at least one second exciter that is connected via a universal intermediate shaft to the first exciter.

4. The vibrating machine according to claim 1, wherein the inertial sensor is provided at, in, or on a housing of at least one exciter.

5. The vibrating machine according to claim 1, wherein the condition-monitoring device evaluates a vibration behavior of the vibrating machine in relation to state variables that include:

acceleration amplitude, yaw-rate amplitude, vector change of the impact indicator, phase shift, and/or THD or harmonic distortion individually or in combination with one another.

6. The vibrating machine according to claim 1, further comprising an electronic evaluation device for receiving measured data of the inertial sensor or the inertial sensors and for evaluating the measured data in relation to state variables including:

acceleration amplitude, yaw-rate amplitude, vector change of the impact indicator, phase shift, and/or THD or harmonic distortion individually or in combination with one another.

7. The vibrating machine according to claim 6, wherein the electronic evaluation device is provided for a comparative examination of the determined state variables and defined limit values.

8. The vibrating machine according to claim 7, wherein an absolute value is provided as the defined limit value.

9. The vibrating machine according to claim 7, wherein an initial value with a tolerance range is provided as the defined limit value.

10. The vibrating machine according to claim 1, wherein the electronic evaluation device comprises a display for showing state variables and/or a warning display or a warning signal generator when defined limit values are exceeded.

11. The vibrating machine according to claim 1, wherein the electronic evaluation device of the condition-monitoring device of the vibrating machine and a device for measured data acquisition are provided spatially separated from one another.

12. The vibrating machine according to claim 1, wherein the connection between the electronic evaluation device and the device for measured data acquisition is provided wirelessly.
