ROTARY-BLADE HYDRAULIC TURBINE WHEEL

摘要

FIELD: engines and pumps. ^ SUBSTANCE: invention relates to power engineering. Rotary-blade hydraulic turbine wheel incorporates a body with openings and a blades turning mechanism. Blades incorporating trunnions run in plain bearings arranged in the said openings. The said mechanism levers are fitted in trunnions and represent circular parts with lugs extending therefrom. Backup rings are fitted on the trunnions at the point they pass into the blade on the body outer side. The said backup rings have the OD greater than body openings diameters. The lever circular parts ODs are smaller than the openings diameter. ^ EFFECT: better manufacturability and reduced metal intensity. ^ 2 dwg
