BEARING ARRANGEMENT |
摘要 |
A bearing arrangement between shafts of a fluid flow engine, especially including a high pressure turbine and/or a lower pressure turbine, includes a damping gap for the controllable formation of a carrier film between an outer bearing race and a bearing mounting member. A damping fluid is introduced into the damping gap of a squirrel cage bearing. The outer bearing race rotates with an r.p.m. corresponding to that of the high pressure turbine shaft r.p.m. or to that of the low pressure turbine shaft r.p.m. The damping fluid is supplied through a channel passing through the low pressure turbine shaft and into an entrapment chamber just at the entrance end of the damping gap, whereby the rotation of the entrapment chamber compresses the damping fluid by a centrifugal force into the damping gap. |
