Patent ES-387528-A1 (ES)
Title: Axial water flow machines
IPC: F04D29/18
Filed: 1971-01-22
Abstract: In an axial water flow pump or turbine in which the runner comprises a hub, vanes extending radially from the hub, and a rim disposed around the vanes for example for carrying an electrical rotor, the rim is attached to the hub by tie bars. Preferably one tie bar is associated with each vane and extends through a bore or slot formed in the vane. Whilst tangential forces can be transmitted between the rim and the hub by the vanes, radial forces are carried by the tie bars. Thus bending stresses to which the rim is subjected are reduced, the rim will remain more nearly circular and radial clearance between the rim and its surroundings can be reduced.
