FIELD: aircraft engineering.
SUBSTANCE: invention relates to the field of aviation, in particular to the propeller designs. A propeller blade mounting system comprising mounting system (4) on rolling bearings between propeller hub (3) propeller blade (2). At least one bearing outer ring (9) is connected in rotationally fixed manner to propeller blade (2). At least one bearing inner ring (15, 16, 17) is mounted on propeller hub (3). Connected to propeller blade (2), sleeve-shaped central portion (13) is disposed radially inside bearing inner ring (15, 16, 17). Between bearing outer ring (9) and central section (13) in the radial direction relative to the rotational axis (R) of propeller hub (3), outwardly closed lubricant chamber (18) is formed.
EFFECT: simplifies the lubrication system, installation and maintenance of bearings.
