Abstract
A method for operating a plain bearing including: determining a first rotational speed at which a transition of a lubrication state takes place, or at which friction in the plain bearing is at a minimum; comparing the first rotational speed to a threshold value; and if the rotational speed has exceeded the threshold value, operating the bearing to produce a self-repairing effect.
Claims8
A method for operating a plain bearing comprising:
- determining a first rotational speed corresponding to a speed at which a transition of a lubrication state of the plain bearing takes place, or at which friction in the plain bearing is at a minimum;
- comparing the first rotational speed to a predetermined threshold value;
- and
- if the first rotational speed has exceeded the predetermined threshold value, operating the bearing such that mixed friction occurs in a bearing gap of the plain bearing and avoiding boundary friction and liquid friction in the bearing gap of the plain bearing.

A method for operating a plain bearing comprising:
- determining a first rotational speed corresponding to a speed at which, based on a present condition of the plain bearing, a transition of a lubrication state takes place, or at which friction in the plain bearing is at a minimum;
- comparing the first rotational speed to a predetermined threshold value;
- and
- if the first rotational speed exceeds the predetermined threshold value, operating the plain bearing such that mixed friction occurs in a bearing gap of the plain bearing and avoiding boundary friction and liquid friction in the bearing gap of the plain bearing.
