METHOD AND DEVICE FOR LUBRICATING AND COOLING A BEARING THAT IS SUBJECT TO HIGH LOADS

摘要

The invention relates to a method for lubricating and cooling a bearing that is subject to high loads and to a device for carrying out said method. The invention is characterized by dissolving a lubricant in a supercritical gas that is cooled down to a low temperature and feeding the gas/lubricant mixture to the baring. The gas/lubricant mixture is relaxed in the bearing area, thereby releasing the lubricant and lubricating the bearing. The now subcritical gas that is cooled down to a low temperature is used for cooling and is discharged to the exterior. The gas used is carbon dioxide (CO2) and the lubricant is a hydrocarbon-based lubricant.
