Abstract
The invention relates to a method for disposing of a lubricant, preferably oil, of which a controlled supply is provided to a friction bearing, especially a roll neck bearing of a chock. Said lubricant flows into the bearing box and is disposed of below through a lubricant sump. According to said method, the lubricant which has collected in the sump is disposed of upwards with the aid of a vacuum. To this end, the bearing case ( ) is configured with a discharge bore ( ) which extends downwards into the lubricant sump ( ), and is connected to the atmosphere via at least one ventilation bore ( ) situated at the top end of the bearing, and an outlet line ( ). The discharge bore ( ) has a pressure regulating valve ( ) in a line ( ) which is connected to a vacuum source (VQ). Said pressure regulating valve ( ) has an interactive connection to a device for measuring the throughflow of air ( ), said measuring device being located in the outlet line ( ) of the ventilation bore ( ).
