CALCULATION AND DESIGN METHODS OF METAL-CERAMIC DRY FRICTION BEARINGS OF ELECTRIC MOTORS OF SUBMERSIBLE ELECTRIC MACHINES

The article describes the method of calculating the metal-ceramic dry friction bearings of the electric motors of the submersible electric machines. The formulae dependencies and the mathematical apparatus of calculating the metal-ceramic dry friction bearings of the asynchronous electric motors are given. In addition, some characteristic features of the influence of the increased temperature of the bearing on the pressure and speed, as well as its service life, are considered. The strength criterion, the wear criterion, the heat resistance criterion, the criterion of optimal working clearances for the sliding pairs are considered.
