BLADE OPERATING GEAR FOR HYDRAULIC-TURBINE WICKET-GATE MECHANISM |
摘要 |
FIELD: hydroelectric power engineering. SUBSTANCE: blade operating gear has split blade lever 4 braced by means of bolt 6 and mounted on intermediate bushing 2. The latter is installed on blade trunnion 7 and fixed to the latter by key (keys) 3 arranged near plane perpendicular to axis of bolt 6 and passed through blade axis or near mentioned plane. Blade operating gear is provided with guaranteed design clearances between intermediate bushing 2 and trunnion 7 as well as between the latter and lever 4 to ensure non- cylindrical shape of lever and bushing so as to ensure additional mechanical linkage between parts transmitting rotary motion from lever 4 to trunnion 7 and vice versa. EFFECT: improved design. 8 dwg
