Bearing arrangement for the rudder blades of a steerable missile

摘要

Shaft journals (20) of the rudder blade mountings (16) are rigidly connected to be resistant to torsion via a coupling element (32). An annular element (28) is between a first annular shoulder (24) on the shaft journal and a second annular shoulder (26) on a rear structure (10) of the missile, so there is axial play (30). The coupling element may be eccentric, a bellows, or an arcuate protuberance.
