Bearing device for vertical rotating machine |
摘要 |
A bearing device for supporting a rotating shaft substantially arranged in a vertical direction in a vertical rotation machine is disclosed. The bearing device enables the vertical rotation machine to operate in a stable and contamination-free condition by preventing leakage of lubricant as well as to decrease the lubricant consumption. The bearing device comprises a roller bearing for supporting the rotating shaft and a labyrinth seal provided below the bearing. An oil dam is provided at a bottom portion of a bearing chamber to surround the sealing. An oil suction pipe for discharging lubricant from the oil dam, a sealing gas supply passage for supplying sealing gas into the bearing chamber from below by way of the sealing, and a sealing gas vent port opening at an upper area of the bearing chamber are provided.
