Description

На схематическом чертеже фиг. 1 изображает частичный вид спереди предлагаемого пропеллера и фиг, 2- вид сбоку, частью в разрезе.In the schematic drawing of FIG. 1 shows a partial front view of the proposed propeller and FIG. 2 is a side view, partly in section.

Через металлическую ступицу 1 (фиг. 1,2) пропеллера пропущены в противоположные стороны внутренние концы лопастей 2, закрепленные стопорными кольцами 4. Концы лопастей снабжены черв чной йарезкой 5, сцепленной с винтовыми шестерн ми 6. Последние имеют внутреннюю нарезку 7 с крупным шагом, через которую проход т винты 8, соединенные с муфтой 9, скольз щей на валу 10 по шпонке 11. При выдвигании руко ткой 12 винтов 8 из шестерен 6, последние поворачиваютс  на месте, враща  лопасти 2 благодар  нарезкам 5, чем достигаетс  изменение шага воздушного винта.Through the metal hub 1 (fig. 1, 2) of the propeller, the inner ends of the blades 2, fixed by retaining rings 4, are passed in opposite directions. The ends of the blades are equipped with a worm thread 5, coupled with helical gears 6. through which the screws 8, connected to the coupling 9, sliding on the shaft 10 through the key 11, extend. When the knob advances 12 screws 8 from the gears 6, the latter rotate in place, rotating the blades 2 due to cuts 5, thereby changing the pitch of the aerial view. ta.
