AXIAL FAN Russian patent published in 2012 - IPC F04D19/00 F04D25/06 F04D29/66 

FIELD: mechanics.

SUBSTANCE: indicated technological result is achieved in the axial fan, containing the body, in the inner diametrical surface of which, straightener blades in a shape of liners with blades are firmly attached, a shell with firmly attached to it electro-motor with mounted operating wheel to its dike with blades and with two round shock-absorber in shell's outer surface, are placed inside the liner. Each of them with one edge rests one of the two locking stop on the opposite edges of the shell and is located between these locking stops, at that, it is supplied with firmly installed a cylindrical bearing in the cylindrical cage which wraps up around the shell, made no less than two components, divided by flat parting surfaces, parallel to the fan's axes, at that, the angular measures of each part of the insert in relation to the fan's axes does not measure more than 180°. On one insert's end a flaring flange adaptor is set, and in the inner surface of the insert, an inner clamp is set, with connects with its ends with the end of the circular shock-absorbers. The straightener blades' plug from the side of the closest end to the operating wheel is supplied with a exerted inside flange adaptor, the cage is located inside the outlet straightener plug and is connected to outlet straightener flange adaptor with threaded fasteners, and the flange adaptor of the insert is located with pressure between flange adaptor plug of the outlet straightener and the cage's end, at that both, the shell's locking stops are located inside the insert and their outer cylindrical surfaces are installed relatively to the inner cylindrical surface of the insert with a radial clearance.

EFFECT: device refers to ventilation and can be used as a part of the temperature control system for space engineering, allowing to increase the manufacturing of fans as well as to widen the scope of use and also reduce the mass.
