Abstract
The utility model discloses a novel no-power air blower, comprising a turbine host, a middle loop, a middle seat, and a base plate seat, in the middle loop, one end of a main shaft goes through a cylinder cover and is inserted into an oil cylinder, two bearings are installed, the cylinder cover covers the oil cylinder end opening, three supporting rods fix and support the oil cylinder. The oil cylinder with the cylinder cover provides a sealed operation environment for the bearings of the air blower, a blast cap installed on the turbine host at the upper end of the main shaft is designed to be in a fixed connection with the main shaft, the above two improvements prevent gases characterized by high temperature, corrosivity, high dust, etc. from eroding the bearings, thereby reducing loss of bearings, prolonging service lifetime of bearing, reducing cost, and improving production efficiency.
Description
Technical field
The utility model relates to a kind of novel unpowered blower fan.
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.
The bearing of old-fashioned unpowered blower fan is because often directly contact with air, and the gas of industrial premises is generally high temperature and contain corrosive material and dust etc., therefore not only cause the lubricating grease of bearing to be dried rapidly, and dust and corrosive material are invaded bearing inside easily, can directly cause the bearing rotation not smooth, and then the acceleration bearing wear, up to thoroughly scrapping, cause the blower fan stall.And old-fashioned unpowered blower fan, bearing are positioned at the two ends of axle, the bearing apart from each other, and the coaxality of bearing is difficult to improve, and makes that the rotation of axle is smooth inadequately, causes the exhaust velocity of blower fan not maximize.
Traditional unpowered blower fan can only be by the dismounting blower fan, and the mode of changing bearing prolongs the working life of blower fan.But the appearance that same problem still can be gone round and begun again not only can not tackle the problem at its root, and the every dismounting of blower fan once, brings great negative effect will for the anti-drainage facility of factory building roof structure and blower fan.
The model utility content
The utility model provides a kind of novel unpowered blower fan, can overcome the problem of above existence.
For achieving the above object, by the following technical solutions:
A kind of novel unpowered blower fan, its composition comprises the turbine main frame, centre circle, middle seat and bottom block, middle seat is installed on the described bottom block, centre circle is installed on it, three supporting rods in the centre circle are with the oil cylinder fixed support, main shaft one end passes cylinder cap and inserts in the oil cylinder, and two bearings are installed, fill lubricant oil in the oil cylinder, cylinder cap covers the oil cylinder port, so just with bearing seal in oil cylinder, make bearing with the condition of isolate from outer air under turn round, and the blast cap that the main shaft upper end is installed on the turbine main frame is designed to fixedly connected with main shaft, therefore rotational parts such as bearing also need not be installed, the corrosion of bearing has been avoided in these two improvement, effectively reduces wearing and tearing, has improved the working life of blower fan.
Further, because one or two bearing of rotatable parts of described blower fan, all be fixed in the oil cylinder of main shaft one end, the distance of two pieces of bearings is shortened greatly, and its coaxality is guaranteed by axle and oil cylinder two aspects, make that the rotate effect of blower fan is smooth more with respect to old-fashioned blower fan, exhaust velocity is faster.
Description of drawings
According to embodiment and accompanying drawing the utility model is described in further detail below.
Fig. 1 is the general structure schematic representation of novel unpowered blower fan described in the utility model;
Fig. 2 is the partial enlarged drawing of A place oil cylinder, bearing part among Fig. 1.
Among the figure:
1, turbine main frame; 2, centre circle; 3, middle seat; 4, bottom block; 5, main shaft; 6, jump ring; 7, lubricant oil; 8, strut; 9, cylinder cap; 10, clutch shaft bearing; 11, oil cylinder; 12, second bearing; 13, blast cap.
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 and bottom block 4, seat 3 in being equipped with on the bottom block 4, centre circle 2 is installed on the middle seat 3, three struts 8 are housed, the arc end support fixation position oil cylinder 11 of strut 8 on it; One end of main shaft 5 passes cylinder cap 9 and inserts oil cylinders 11, and the clutch shaft bearing 10 and second bearing 12 are installed, wherein main shaft 5 be positioned at bearing 10 below jump ring 6 is housed; Turbine main frame 1 is installed on the main shaft 5; Lubricant oil 7 will be filled with in the oil cylinder 11, cover tight cylinder cap 9, then the clutch shaft bearing 10 and second bearing 12 are enclosed in the environment of a sealing, when gas drives main shaft 5 rotations by turbine main frame 1, the clutch shaft bearing 10 and second bearing 12 turn round in sealed cylinder 9, and turbine main frame 1 drives blast cap 13 and main shaft 5 rotates together.
