Submarine, has spindle drive including shaft joint arranged outside pressure hull and hollow shaft rotating spindle connected to rudder, where hollow shaft retracts spindle

摘要

The submarine has a spindle drive (7) with a shaft joint defined at a submarine body (1) around a swivel axis (13), where the shaft joint is arranged outside a pressure hull. The spindle drive has a hollow shaft (6) that is driven by a motor within the hull in order to rotate a spindle connected to a rudder (15). The hollow shaft has a diameter larger than that of the spindle, such that the shaft retracts the spindle.
