Further, the screwed hole runs through axle sleeve, and the length of the screwed hole is less than the length of threaded post.
Compared to existing technology, the beneficial effects of the utility model are：A kind of cross flow blower described in the utility model,
Its motor output shaft is chamfered edge axle, and screw supported on mounting surface through axle sleeve；Post is threaded on motor output shaft, in wind wheel
Axle sleeve on recessed screwed hole, by the connection of threaded post and screwed hole, prevent wind wheel from coming off with motor output shaft, safety is surely
Fixed, simple structure, easy accessibility.
Description of the drawings
Fig. 1 shows a kind of schematic diagram of cross flow blower described in the utility model；
Fig. 2 shows a kind of explosive view of cross flow blower shown in Fig. 1；
Fig. 3 shows a kind of partial sectional view of cross flow blower shown in Fig. 1.
Wherein, 1 is motor, and 11 is motor output shaft, and 111 is mounting surface, and 12 is threaded post, and 2 is wind wheel, and 21 is axle sleeve,
22 is connecting hole, and 23 is screwed hole, 24 fixing holes, and 3 is screw.
Specific embodiment
With reference to the accompanying drawings and detailed description this utility model is described in further detail.
As shown in Figure 1-2, a kind of cross flow blower described in the utility model, including motor 1, and is set in motor output
Wind wheel 2 on axle 11.The motor output shaft 11 is a chamfered edge axle, and its side wall is concavely provided with mounting surface 111, the mounting surface
111 is a plane.The end of the motor output shaft 11 stretches out and is formed with threaded post 12, and the threaded post 12 is defeated with motor
Shaft 11 is coaxially disposed, and the diameter of the threaded post 12 is less than motor output shaft 11.
As shown in figure 3, one end of the wind wheel 2 is fixedly installed axle sleeve 21, the axle sleeve 21 is coaxially disposed with wind wheel 2.
The axle sleeve 21 is arranged with the connecting hole 22 matched with motor output shaft 11, depth of the connecting hole 22 etc. along its axis
In the length of mounting surface 111, the connecting hole 22 is a circular hole, and the axle sleeve 21 is set in motor output shaft by connecting hole 22
On 11.The axle sleeve 21 is arranged with the screw thread matched with threaded post 12 in connecting hole 22 in the one end away from motor output shaft 11
Hole 23, the axis of the screwed hole 23 are overlapped with the axis of connecting hole 22.Preferably, the screwed hole 23 runs through axle sleeve
21, the length of the screwed hole 23 is less than the length of threaded post 12.Fixing hole 24 is provided through on the side wall of the axle sleeve 21,
Female thread is provided with the fixing hole 24, and the axis of the fixing hole 24 is perpendicular with the axis of axle sleeve 21.
During installation, connecting hole 22 is set on motor output shaft 11, threaded post 12 is screwed into by rotary electric machine output shaft 11
In screwed hole 23；Angle between adjustment motor output shaft 11 and axle sleeve 21 so that the axis of mounting surface 111 and fixing hole 24
Vertically, screw 3 is screwed in fixing hole 24 so that one end of screw 3 is supported on mounting surface 111 so that motor output shaft 11
It is relatively fixed between axle sleeve 21, it is impossible to rotate；When screw 3 loosens, between motor output shaft 11 and axle sleeve 21, pass through screw thread
