FIELD: engines and pumps.
SUBSTANCE: invention can be used in development of axial fan impellers. Proposed impeller comprises hub 1 furnished with ring 2 and bores accommodating rotary pairs of blades 3. The latter have rotary axle 8 and cup 4 articulated with toothed rack 6 of the device designed to make said axle and cup rotate. Every cup is fixed, via bearing units 7, on axle 8 rigidly fixed on hub 1. Note here that every pair of blades 3 is articulated, via cup 4, with rotation drive of blades 3.
EFFECT: higher reliability and simple design, lower weight and reduced radial and inertial loads on impeller and bearing units.
