Abstract
PURPOSE: To form stable water film in the aperture between a main shaft and a bearing all the time by providing plural axial grooves in the inner surface of the bearing material of Teflon resin, etc., in a water-lubricated bearing device of a dynamic pressure type for the hydraulic machinery in a hydroelectric power station or the like.
CONSTITUTION: Fresh water for libricating purpose is sent through a water supply pipe 5 into a water supply chamber 4 provided in the lower part of a housing 2 and then flowed upwards along grooves 9 provided in the inner surface of a bearing material 1 made of Teflon resin, etc., supporting a main shaft 3 because the lower part of the water supply chamber 4 is closed with a packing 7 provided inside a water sealing box 6. And, the fresh water in the grooves 9, having a static pressure because the upper end of the grooves 9 is throttled in a slit form, flows into an aperture between the main shaft 3 and the bearing material 1 as the main shaft 3 rotates to form stable water film over the whole surface of the bearing. Also, a labyrinth 8 provided at the upper part of the housing 2 supports the resisting action of the slit pant of the grooves 9.
