Abstract

Przedmiotem zgłoszenia jest piasta wirnika nośnego. Charakteryzuje się ona tym, że piasta (1) od strony przeciwnej do strony jej montażu posiada otwór (1.1), w którym znajduje się przycisk odblokowujący (2), posiadający od strony mocowania piasty (1) dwa kliny (2.1, 2.2) ułożone naprzeciwko siebie po dwóch stronach osi piasty (1) i posiadające powierzchnię pochyloną pod kątem ostrym do osi piasty (1) od wewnętrznej strony piasty (1). Każdy z klinów (2.1, 2.2) przycisku (2) zazębiony jest z jednym z klinów znajdującym się na sworzniu blokującym (3, 4) ułożonych współosiowo i umiejscowionych w otworach znajdujących się w jarzmie łopat. Pomiędzy sworzniami blokującymi (3, 4) znajduje się sprężyna naciskowa (6).The subject of the application is the hub of the main rotor. It is characterized by the fact that the hub (1) on the side opposite to its mounting side has a hole (1.1) in which the unlocking button (2) is located, with two wedges (2.1, 2.2) arranged opposite to the hub mounting side (1). each other on two sides of the hub axis (1) and having a surface inclined at an acute angle to the hub axis (1) on the inner side of the hub (1). Each of the wedges (2.1, 2.2) of the button (2) is meshed with one of the wedges located on the locking pin (3, 4) arranged coaxially and located in the holes located in the blade yoke. Between the locking pins (3, 4) there is a compression spring (6).
