Elastic joint between a driving and a driven shaft.

摘要

The invention relates to an elastic joint 1 connecting a driving shaft 2 to a driven shaft 3. The joint consists of a socket 5 engaged in a recess 4 of approximately the same cross-section let into the driven shaft, the socket having a housing 13 in which is engaged the driving shaft and comprising a first elastic means arranged between the driven shaft and the socket and a second elastic means between the socket and the driving shaft, to provide a play-free coupling between the driving shaft and the driven shaft. The first elastic means consists of at least one arm 6 or 7 comprising two branches 8 and 9, at least one of which is deformable and provides a constant pressure on the walls 10 and 11 of the recess. The second elastic means consists of at least one lamella 14 or 15 applying constant pressure on the driving shaft. The first elastic means consists of two arms 6 and 7 placed on each side of the socket on its axis XX' of symmetry. The two branches 8 and 9 can be pushed towards each other in order to absorb clearances of assembly between the driven shaft and the socket. Application to the control of projectile fins. <IMAGE>
