Abstract
The utility model provides a ventilating device with an internally inlaid rotating shaft supporting frame. The ventilating device is formed by an air flue shell, a fan, a motor, support outer rings, cross-shaped spokes and the like. When the motor (10) is powered on and works to drive the fan (9) to rotate, airflow sucked into the air flue shell (1) flows from a fan mounting section (7) to a motor mounting section (8). Three identical bearing supports (2) ensure the stable supporting strength of the fan (9) and the motor (10) and isolate the mutual interference between the fan (9) and the motor (10). The cross-shaped spokes (5) ensure the supporting strength of the bearing supports (2) and can enable airflow to smoothly pass through the interior of the air flue shell (1). The ventilating device can be inlaid in an air flue for use and can also supply a power source to a road opening wind tunnel.
Description
(1) technical field
The present invention relates to a kind of ventilation unit, belong to a kind of ventilation unit of interior edge rotating shaft support frame.
(2) technical background
For provided with fan and motor in the air channel of limited space, should guarantee support strength and the stability of fan and motor, simultaneously can't be too much take available ventilation cross section in air channel, need one in air channel, both to there is support strength and stability, seldom take again the rotating shaft support frame in available ventilation cross section in air channel.
(3) summary of the invention
The purpose of this utility model is to provide a kind of ventilation unit of interior edge rotating shaft support frame, for solving provided with fan and motor in the air channel of limited space, should guarantee support strength and the stability of fan and motor, the technical problem that takies available ventilation cross section in air channel that simultaneously can't be too much.
The purpose of this utility model is to realize like this, it contains air channel housing, fan, fan electromotor axle and motor, it is characterized in that: also contain bearing holder (housing, cover), support outer ring, criss-cross spoke, in the housing of air channel housing 1, be axially equipped with three identical supports of bearing 2, in the support outer ring 3 of the support of bearing 2, be enclosed within the housing of air channel housing 1, support outer ring 3 profiles are circular, the center of the support of bearing 2 is bearing holder (housing, cover)s 4, criss-cross spoke 5 connection bracket outer rings 3 and bearing holder (housing, cover) 4, criss-cross spoke 5 profiles are cross, coaxial provided with fan motor shaft 6 on the support of bearing 2, three identical supports of bearing 2 will be divided into fan construction section 7 and motor construction section 8 vertically in air channel housing 1 housing, provided with fan 9 on the fan electromotor axle 6 of fan construction section 7, mounted motor 10 on the fan electromotor axle 6 of motor construction section 8.
The support of bearing 2 of supports fan 9 and motor 10 is complete in the housing of air channel housing 1, thereby the utility model is a kind of ventilation unit of interior edge rotating shaft support frame.The beneficial effects of the utility model are: provided with fan and motor in the air channel of limited space, can guarantee support strength and the stability of fan and motor, simultaneously also need not be too much take available ventilation cross section in air channel.
(4) accompanying drawing explanation
Fig. 1 is the structural representation of the utility model embodiment, and Fig. 2 is the structural representation of the utility model embodiment support of bearing 2.
(5) specific embodiment
See figures.1.and.2, in the present embodiment, in the housing of air channel housing 1, be axially equipped with three identical supports of bearing 2, in the support outer ring 3 of the support of bearing 2, be enclosed within the housing of air channel housing 1, support outer ring 3 profiles are circular, the center of the support of bearing 2 is bearing holder (housing, cover)s 4, crosswise spoke 5 connection bracket outer rings 3 and bearing holder (housing, cover) 4, criss-cross spoke 5 profiles are cross, object is the support strength that can guarantee the support of bearing 2, can make again air fluid smoothly by the housing of air channel housing 1, at bearing, prop up coaxial provided with fan motor shaft 6 on 2, three identical supports of bearing 2 will be divided into fan construction section 7 and motor construction section 8 vertically in air channel housing 1 housing, object is to guarantee that fan 9 and motor 10 have firm support strength, can isolate again the phase mutual interference between fan 9 and motor 10, provided with fan 9 on the fan electromotor axle 6 of fan construction section 7, for generation of air mass flow, flow velocity and pressure, mounted motor 10 on the fan electromotor axle 6 of motor construction section 8, the harmful heat producing while utilizing air stream cooling motor 10 in air channel housing 1 to work.
Operation principle: as depicted in figs. 1 and 2, motor 10 energising work, while driving fan 9 to rotate, air stream in suction air channel housing 1 is from fan construction section 7 side flow direction motor construction section 8 sides, three identical supports of bearing 2 have guaranteed that fan 9 and motor 10 have firm support strength, isolated the phase mutual interference between fan 9 and motor 10, criss-cross spoke 5 has guaranteed the support strength of the support of bearing 2, can make again air fluid smoothly by the housing of air channel housing 1.
