METHOD FOR MANUFACTURING BLADE OPERATING MECHANISM LEVER FOR HYDRAULIC TURBINE RUNNER

摘要

FIELD: Kaplan turbine manufacture. SUBSTANCE: forging is made in the form of hollow cylinder whose outer diameter corresponds to maximum size of lever in plane transverse relative to its axis and its length corresponds to at least that of pair of levers if they were folded together with their spindles opposing and were relatively turned through 180 deg.. Each separate lever is obtained from this forging by cutting the latter into parts corresponding to levers size followed by shaping the lever by cutting its outline. EFFECT: facilitated procedure. 4 dwge
