Abstract
The utility model discloses a powerless fan with a spindle integrated with a cap, which comprises the cap, the spindle, a turbine unit host, a middle ring, a middle base and a bottom plate seat. One end of the spindle is positioned on the middle base and connected with the middle base by a rotating component, a bearing and the like, and the upper end of the spindle is fixedly connected with the cap mounted on the turbine unit host. By the aid of the improvement, rotatable components of the fan are reduced, so that abrasive and corrosive components of the fan are reduced, the integral service life of the fan is prolonged, cost is decreased, and production efficiency is improved.
Description
Technical field
The utility model relates to the unpowered blower fan of a kind of axle cap one.
Background technique
In buildings such as industrial premises, often use unpowered blower fan exhaust ventilation, this kind blower fan does not need the people for power is provided, and its power is mainly derived from the hot air flow of indoor rising and outdoor natural wind, drive the rotation of turbine main frame, thereby reach the effect of ventilation.Be rotationally connected by parts such as bearings between the blast cap of old-fashioned unpowered blower fan and the blower fan main shaft, this just makes blower fan axle head and blast cap joint enter dust or corrosivity particulate easily, the wearing and tearing of blower fan main shaft have been accelerated, make that the working life of blower fan main shaft and blast cap is lower, reduce the utilization efficiency of blower fan, increased cost of production.
The model utility content
The utility model provides a kind of axle cap one unpowered blower fan, can overcome the problem of above existence.
For achieving the above object, by the following technical solutions:
The unpowered blower fan of a kind of axle cap one, its composition comprises the turbine main frame, centre circle, middle seat, bottom block and blast cap, middle seat is installed on the described bottom block, centre circle is installed on it, main shaft lower end and middle seat are rotationally connected by bearing, the turbine main frame is passed in the upper end, insert the blast cap on turbine main frame top, the main shaft top and the blast cap of this kind blower fan are fixed together, and can adopt fixedly connected modes such as welding, make that blast cap and main shaft can not relative movement, such improvement has reduced the movable link that blower fan constitutes, and has therefore reduced the parts of the frayed of blower fan and corrosion, makes the blower fan bulk life time be improved, reduce cost, improved manufacturing efficiency.
Description of drawings
According to embodiment and accompanying drawing the utility model is described in further detail below.
Fig. 1 is the unpowered blower fan general structure of an a kind of axle cap one described in the utility model schematic representation;
Fig. 2 is Fig. 1 Apoplexy cap and joint, main shaft top cutaway view Amplified image.
Among the figure:
1, turbine main frame; 2, centre circle; 3, middle seat; 4, bottom block; 5, blast cap; 6, main shaft; 7, screw.
Embodiment
As shown in Figures 1 to 3, provided a specific embodiment of novel unpowered blower fan described in the utility model, its composition comprises turbine main frame 1, centre circle 2, middle seat 3, bottom block 4 and blast cap 5, seat 3 in being equipped with on the bottom block 4, centre circle 2 is installed on the middle seat 3, one end of main shaft 6 inserts centre circle, be rotationally connected by formation such as bearings with centre circle, the other end passes turbine main frame 1, blast cap 5 is inserted on the top, blast cap 5 is fixedly mounted on turbine main frame 1 top by screw 7, and weld together with main shaft 6 tops, when turbine main frame 1 rotates, drive main shaft 6 and blast cap 5 and rotate together like this, make the rotatable parts of blower fan greatly reduce, the blower fan member is worn and the probability that corrodes greatly reduces.
Claims (1)
