SHORTENED EXTENSIBLE PROPELLER SHAFT Russian patent published in 2002 - IPC

FIELD: transport engineering. SUBSTANCE: invention relates to drives of vehicles and stationary plants in which relative displacements of driving and driven sets are possible. Proposed propeller shaft has joints connected by movable splined joints to transmit torque from driving to driven shafts arranged at angle relative to each other. Movable splined joints provides axial displacement of shafts relative to each other. Splines of movable splined joints are spaced in radial direction to sizes exceeding radial sizes of propeller shaft joints and they enclose the joints either completely or partially. EFFECT: considerable reduction of axial size of propeller shaft with possibility of arrangement of sets to be connected at minimum distance from each other. 2 dwg _
