Abstract

Способ крепления лопасти к ступице колеса, отличающийся тем, что лопасти устанавливают с натягом в радиальные пазы ступицы колеса, при этом изогнутые под углом 90° концы лопастей вставляют в продольные пазы цилиндрических штифтов, установленных с натягом в отверстиях, примыкающих к пазам ступицы и расположенных на одном расстоянии от центра колеса.The method of mounting the blades to the wheel hub, characterized in that the blades are tightened into the radial grooves of the wheel hub, while the ends of the blades bent at an angle of 90 ° are inserted into the longitudinal grooves of the cylindrical pins installed with an interference fit in the holes adjacent to the grooves of the hub and located on one distance from the center of the wheel.
