Abstract (en)
[origin: RU2643907C1] FIELD: ventilation.SUBSTANCE: fan-side channel blower includes (12) with a hole (14) to the shaft, which is rotating around an axis (a) rotation (20) fan motor-blower, and the shaft (20) with respect to motor Hull (12) fan-blower installed using bearing (32) shaft. Bearing (32) shaft includes a hardcoded on the shaft (20) of the electric motor of the inner ring (34) bearing and hardcoded in the hull (12) fan-blower outer ring (36) bearing. The shaft hole (14) in the axial end region (16) has a first radial expansion region (38) for preparing the bearing space (40). The outer ring (36) of the bearing is fixed axially between the annular bottom region (44) of the first radial expansion region (38) and the annular region (50) of the plastic shaping of the blower fan housing (12).EFFECT: efficiency enhancement.10 cl, 4 dwg
