DOUBLE CONNECTION SHAFT PREVENTED FROM BEING TORSIONALLY RESONATED

摘要

PROBLEM TO BE SOLVED: To provide a connection shaft, the torsional vibration of which is suppressed by a simple structure without lowering rigidity. SOLUTION: This double connection shaft of inner and outer double shaft structure comprises a cylindrical outer connection shaft S11having a connection flange part 3 at both ends and an inner connection shaft S12 allowed to be inserted into the hollow hole 1 of the outer connection shaft S11with a predetermined gap 2 interposed therebetween and having a torsional spring constant different from that of the outer connection shaft S11. The gap 2 between the both outer and inner connection shafts S11, S12is filled with an elastic resin adhesive agent R. The axial ends of one of both connection shafts S11, S12 are integrally connected to each other by welding (fixing means) W. COPYRIGHT: (C)2008,JPO&INPIT
