INTER-SHAFT BEARING APPARATUS OF MULTIPLE BARREL TYPE TURBINE ENGINE

摘要

In a multi-spool turbo machine, a first shaft of the low pressure spool is supported for rotation with respect to a second shaft of the high pressure spool and is located with respect to the second shaft by means of a roller bearing. Rollers of the bearing are inserted between an internal ring mounted on the second shaft and an outer ring mounted by a ring support assembly carried by the first shaft. The ring support assembly includes a ring support member which comprises, at its outer periphery, a first toothed element cooperating with a second toothed element carried by retaining means. The ring support member is held axially by a channel-section member.
