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 (1) is configured with a discharge bore (10) which extends downwards into the lubricant sump (9), and is connected to the atmosphere via at least one ventilation bore (17) situated at the top end of the bearing, and an outlet line (15, 16). The discharge bore (10) has a pressure regulating valve (13) in a line (12) which is connected to a vacuum source (VQ). Said pressure regulating valve (13) has an interactive connection to a device for measuring the throughflow of air (14), said measuring device being located in the outlet line (15) of the ventilation bore (17). |
