Abstract
A method for monitoring a linear guide with a carriage that can be displaced along a rail on a lubricated rolling contact is provided having a sensor device for detecting a state of a lubricant for lubricating the rolling contact. In order to allow a quick determination of the state of the lubricant with simple measures, an oscillation time signal is detected by a sensor device from which a characteristic value that increases with increasing degradation of the lubricant is determined by an effective value determination after high-pass filtering. When the characteristic value exceeds a specified threshold value, measures are initiated for improving the lubricating properties.

A method for monitoring a linear guide with a carriage that can be displaced along a rail on a lubricated rolling contact having a sensor device for detecting a state of a lubricant for lubricating the rolling contact, the method comprising:
- detecting an oscillation time signal using the sensor device, determining a characteristic value that increases with increasing degradation of the lubricant using an effective value determination from the oscillation time signal after a high-pass filtering, and when the characteristic value exceeds a specified threshold value, initiating measures for improving lubricating properties.
