Abstract

The article considers the effectiveness of wick lubrication and thermal state of the high-speed rolling bearings of the turbo-refrigerator rotor. Shown that the inside track bearing turbo-refrigerator overheats because of areas of dry friction. The authors found that zone of dry friction disappears after installing a conical insert in front of bearing ensuring the flow of oil-air mixture in the direction inside track bearing.
