Abstract
The carbon fibre reinforced plastics tube (1) is provided at each end with a cemented-in sleeve (2) and a cemented-on sleeve (3) made of the same material and having the same anisotropy behaviour. A fitting (4) is inserted into each end of the tube to introduce a torque and is secured by bolts (5). The bolts are secured by a sleeve (6). The securing of the fittings by bolts and the adapted structure of the wall reinforcements ensure a safe introduction of torque, even into extremely anisotropic tubes.
Claims15
A power transmission shaft, comprising a plastics tube reinforced by fibres of high stiffness, fittings secured to its two ends and at each end of the tube a wall reinforcement of fibre reinforced plastics tapering towards the middle of the tube, the wall reinforcment fibre structure being similar to that of the tube so that the tube and the wall reinforcements have at least approximately the same anisotropic behaviour, and radial bolts located in the region of the wall reinforcements securing said fittings to said tube.
