Abstract
The utility model discloses a circulating fan, which comprises a case, an impeller, an impeller shaft and a foot pipe, wherein the impeller is arranged in the case, the connecting end of the impeller shaft and the foot pipe are positioned at both sides of the case, and the connecting end of the impeller shaft is connected with a motor. Thereby, the installation direction of the impeller in the case can be changed, the connecting end of the impeller and the motor is arranged at the other side of the foot pipe, the installation of the motor can not be limited by the foot pipe, and the motor can be freely arranged at the space.
Description
Technical field
The utility model relates to the blower fan field, especially relates to a kind of straight connection type circulating fan.
Background technique
Present industrial circulating fan is made up of shell, impeller and pin pipe, and impeller is installed in the shell of blower fan, and motor is connected with flow blower casing by flange, and impeller is connected in the rotating shaft of motor.During use, the driven by motor wheel rotation, wind enters from the shell suction port that is positioned at the impeller front, discharges from outlet radially.Usually, motor and pin pipe are positioned at the same side of impeller housing, because there is the pin pipe to exist, the installing space of motor and coupling is subjected to certain restriction, so not only need the space mounting motor that provides enough, and also restricted to the installing space of blower fan own.The Chinese utility model patent specification of the CN2661975Y that on December 8th, 2004 was announced discloses a kind of hot air circulation blower, and this blower fan is arranged on the side that blower fan is provided with the pin pipe with motor, has brought restriction for the installing space of motor and coupling.
The model utility content
The utility model mainly is to solve the side that the motor that exists in the prior art and pin pipe are arranged on flow blower casing, the problem that the installing space of motor and coupling is restricted, a kind of circulating fan is provided, motor has been installed on this blower fan not limited by the pin pipe, the space can freely be arranged.
In order to solve the problems of the technologies described above, the utility model has adopted a kind of like this circulating fan, comprises shell, impeller, impeller shaft and pin pipe, described impeller is installed in the enclosure, the connecting end of described impeller shaft and pin pipe are positioned at the both sides of described shell, and the connecting end of described impeller shaft is connected with motor.Change impeller installation direction in the enclosure like this, the connecting end of impeller and motor is arranged on the opposite side of pin pipe, the installation of motor then can not be subjected to the restriction of pin pipe, and the space can freely be arranged.
As preferably, at the connecting end of described impeller shaft bearing and bearing support are set, described bearing support is connected with described shell, and described bearing is set in described bearing support, and in the bearing support exterior edge face bearing cap is set.Originally only at the rear side of impeller bearing is set, now in the front side of impeller, promptly the connecting end of impeller shaft is provided with bearing and bearing support, can improve the rotational efficienty of impeller shaft like this, reduces wearing and tearing, prolongs the life-span of impeller shaft.
As preferably, in described bearing support, be provided with crossette, described crossette is positioned at described bearing inboard, and the axle envelope is set on described crossette inner side surface.Because the environment oil smoke and the dust of blower fan work are more, on bearing, increase the axle envelope like this, can prevent that oil smoke and dust from entering bearing and damaging bearing, improved the working life of bearing.
The beneficial effects of the utility model are to change impeller installation direction in the enclosure, and the connecting end of impeller and motor is arranged on the opposite side of pin pipe, and the installation of motor then can not be subjected to the restriction of pin pipe, and the space can freely be arranged.

Fig. 2 is the left view of Fig. 1;
Fig. 3 is the enlarged view of a-quadrant among Fig. 1.
Embodiment
Below by embodiment, and in conjunction with the accompanying drawings, the technical solution of the utility model is described in further detail.
As depicted in figs. 1 and 2, a kind of circulating fan of the present utility model comprises shell 1, impeller (not identifying among the figure), impeller shaft 2 and pin pipe 3, and impeller is installed in the shell 1, and the connecting end 4 and the pin pipe 3 of impeller shaft 2 is positioned at the both sides of shell 1.As shown in Figure 3, be provided with bearing support 6 and bearing 5 at the connecting end 4 of impeller shaft 2, bearing support 6 is fixed on the shell 1, and the bearings 5 in the bearing support 6 support the connecting end 4 of impeller shafts 2.Crossette 10 is set in the axis hole of bearing support 6, and crossette 10 is positioned at the inboard of bearing 5, is provided with axle envelope 9 on the inner side surface of crossette 10, with bolt 8 bearing cap 7 is fixed on the bearing support 6.
Motor is connected the connecting end of impeller shaft, the driven by motor wheel rotation, wind enters from the suction port of shell, and the outlet that makes progress from the footpath is got rid of.Owing to the opposite side that the connecting end of impeller shaft is arranged on the pin pipe, when being installed, motor need not consider of the restriction of pin pipe like this for installing space, make the layout of motor and coupling free more.
