KOMBINERAT HYDROSTATISKT/HYDRODYNAMISKT LAGERSYSTEM FOER KVARNAPPARAT.

摘要

Combined hydrostatic/hydrodynamic bearing system for a milling unit in which the material is ground in a mill opening that is defined between a pair of milling devices that rotate relative to each other and in which at least one of the milling devices is supported by an axially moveable rotating shaft 26. One or more cylindrical pistons 30 are mounted on the rotating shaft 26 to rotate with it in a pressure chamber 31, 33 that is defined within a stationary cylindrical housing 32 which causes the piston or pistons 30 to move axially in it. Variations in axial forces that affect the moveable rotating shaft 26 are counteracted by adapting the liquid pressure medium to one or both ends of the piston in the cylindrical piston or cylindrical pistons 30 in a controlled manner so that a predetermined intermediate space is maintained in the milling space. <IMAGE>
