Abstract

The invention relates to a method for monitoring the operation of a plain bearing, whereby a lubricant channel (15), for a bearing segment (11), which is provided for provision of, for example, lifting oil, is used during hydrodynamic operation of the plain bearing for the taking of a sample for a temperature monitoring. A switching device (19) opens a flow path from the lubricant channel (15) into a drain channel (23) to initiate the measuring operation, such that lubricant from the lubricating film (13) flows through the lubricant channel, the temperature of which is determined by a temperature probe (16, 18).

Description

technical field

[0001] The invention relates to a method for monitoring the operation of a plain bearing according to the preamble of claim 1 . The invention also provides a plain bearing which is particularly suitable for carrying out the invention. Background technique

[0002] In hydrostatic or hydrodynamic plain bearings, the actual bearing is assumed by a lubricating film consisting of a liquid (e.g. oil), the temperature measurement of the lubricant in the lubricating film or the temperature measurement on the adjacent sliding surface gives The state of the bearings is therefore particularly well suited for job monitoring.

[0003] EP 0 161 644 discloses monitoring the temperature in the region of the sliding layer on sliding bearings for early detection of damage, so that in the event of a significant temperature increase, preventive measures can be taken in good time. In this case, however, the recording of the temperature change of the lubricating material has a c...
