<p>A hollow shaft 102 for transmitting torsion or bending forces is disclosed. The hollow shaft 102 comprises a first portion 108 having a first wall thickness t 1 , a second portion 110 having a second wall thickness t 2 which is greater than the first wall thickness t 1 , and a transition region 112 between the first and second portions 108, 110. The transition region comprises inner 106 and outer annular 104 shoulder fillets, the inner shoulder fillet 106 being axially offset from the outer shoulder fillet 104 towards the first portion 108. In this manner, the local stress concentrations caused by the inner and outer fillets are axially staggered along the transition region.</p> |
