Guide bearing for vertically mounted rotors, comprises pivoted guide surfaces which are located around a rim on the rotor shaft and are immersed with the rim in a reservoir of lubricating oil

摘要

The rotor shaft (1) has a peripheral rim (1a) which is surrounded by guides (5). The guides are pivoted (4) and have inner faces (5a) which are in close proximity to the outer face (1b) of the rotor shaft rim. The guides and rim are immersed in a reservoir of lubricating oil (2,3) and a coefficient of pressurization (m) which represents the degree of deformation given to the guide surfaces is fixed within 0.96-0.99
