Abstract

661,941. Screw fans and pumps; hydraulic turbines. KONINKLIJKE MACHINEFABRIEK GEB. STORK & CO., N.V. June 22, 1949. [June 23, 1948] No. 16524/49. Classes 110(i) and 110(iii). [Also in Group XXXIII] In a device for adjusting the blades or vanes of an impeller for a fan, pump or hydraulic turbine in which levers 6 eccentrically engaging the stems of the blades 1 are moved by a common adjusting disc 5 which is slidable on the shaft 4 of the impeller but is secured on the shaft for rotation therewith and is connected to the driven member of the adjusting device by a self-locking drive, said driven member is adapted to be disconnected from the driving member. Into the disc 5 spindles 7 are screwed, which spindles are rotatably journalled in a casing 8 keyed to the shaft 4. The spindles are secured against axial movement by a collar 9 and are formed with a pinion 10 which meshes with a toothed wheel 11 freely rotatable on the shaft 4. The wheel 11 is united to a toothed wheel 12 with which a pinion 14 slidable on the adjusting shaft 13 may be brought into mesh. For adjusting the blades the impeller is brought to a standstill, the pinion 14 slid into mesh with the toothed wheel 12, and the shaft 13 rotated by the control mechanism (not shown). When, after adjusting the blades, the pinion 14 is brought out of mesh with the wheel 12 the blades are locked in their position as the screw threaded spindles 7 cannot be rotated by shifting the adjusting disc 5. The control mechanism may be that described in Specification 661,942.
