Specific implementation mode
Be described further below the technical solution of the utility model, but claimed range be not limited to it is described.
As shown in Figure 1 and Figure 2, a kind of mining axial blower, including motor 1, air duct 2, fan hub 3, bearing 7, bearing block 8,
The casing of flabellum 12, the motor 1 is mounted on 2 inside of air duct by motor installation rack 11, and the motor shaft of motor 1 passes through
Axle sleeve 10 is connect with fan hub 3, and the fan hub 3 is connect by connecting shaft 6 with bearing 7, and the bearing 7 is mounted in bearing block 8, institute
It states bearing block 8 to connect with air duct 2 by bearing block mounting bracket 9, the root of the flabellum 12 is equipped with splined shaft 14, and flabellum 12 is logical
It crosses splined shaft 14 to connect with fan hub 3, the welding of 11 steel plate of motor installation rack is made, and steel plate is parallel with the axis of air duct 2, can subtract
The motor shaft of few windage, motor 1 connect by axle sleeve with fan hub 3, and when work passes through motor and drives the fan rotation of hub 3, fan hub 3
Drive flabellum 12 to rotate, be delivered downhole air, meanwhile, flabellum 12 by with airflow direction opposite effect power, active force is logical
The motor shaft and connecting shaft (6) for crossing motor 1 act on the bearing and bearing 7 of motor 1, can be effective by bearing 7
The stress of bearing of motor is reduced, improves service life of equipment, axial flow blower is being typically not shut down for a long time, on motor 1
Nut be susceptible to loosening, be when occurring loosening, since connecting shaft 6 and bearing block 8 can effectively control the inclined of fan hub 3
Pendulum prevents flabellum from scraping air duct inner wall and causes the damage of blade and air duct, when axial flow blower works, passes through connecting shaft 6, bearing
7, bearing block 8 reduce the vibration of fan hub 3, reduce the noise of equipment, as shown in figure 3, the flabellum 12 passes through splined shaft 14 and fan
Corresponding splined hole connection on hub 3, since axis 14 is equipped with multiple teeth, when shutting down, after flabellum nut 5 is unclamped, Gong Renke
The quickly angle of adjustment flabellum 12, to play the purpose for adjusting air quantity and wind pressure, axial flow blower is in addition to the work(with air-supply
Can be outer, the function of exhausting can also be made it have by adjusting the angle of flabellum 12, the toxic and harmful gas of underground can taken out
Go out, protects the safety of underground work.
Flat key 4 is equipped between the motor 1 and fan hub 3, flat key 4 makes the motor shaft of motor 1, fan hub 3, connecting shaft 6
