Abstract
The utility model is an impeller coupler of contra-rotating axial flow fan for air exchange cross ventilation in mine, tunnel and other engineering constructions. The technical proposal of the utility model is characterized in that an impeller shaft is arranged on a bearing seat and connected with a motor shaft by a coupler. During use, both the radial force produced by the weight of the impeller and the axial thrust produced during operation are transmitted to the bearing seat but not the motor; the motor shaft only bears pure torque moment, so that the stress on the motor shaft and the bearing is greatly improved, and the service life of the motor and safety and reliability of a ventilation blower are also improved.
Description
Technical field
The utility model is a kind of impeller hitch bar that the counter-rotating axial fan of air exchange cross ventilation is carried out in engineering constructions such as mine, tunnel that is used for.
Background technique
In existing counter-rotating axial fan, the motor of counter-rotating axial fan is placed in the ventilator casing, two relatively but the opposite impeller of sense of rotation drive by two motors respectively.Impeller and motor adopt the mode of direct connection to be installed on the motor shaft.The end thrust that produces during impeller operation, the radial force that the impeller deadweight produces is all on motor shaft, because motor shaft force-bearing situation complexity during impeller operation, be easy to make motor bearings to damage, even with burn-down of electric motor, not only cause device damage, cause the ventilation of mine working face not smooth easilier, and jeopardize production safety.
Summary of the invention
Goal of the invention of the present utility model will provide a kind of exactly and can improve the motor shaft force-bearing situation, improves the motor counter rotating axial fan in working life.
The technical solution of the utility model is: a kind of counter rotating axial fan, motor 1, impeller 4 are arranged, and it is characterized in that impeller shaft 5 is installed on the bearing support 3, impeller shaft 5 is connected with motor shaft 6 by coupling 2.
During use, the radial force that the impeller deadweight produces, the end thrust that produces during running all reaches on the bearing support, no longer reach on the motor, motor shaft only bears simple moment of torsion, and the force-bearing situation of motor shaft and bearing improves greatly, and the working life of motor and the safety reliability of ventilator are improved.
Description of drawings
Accompanying drawing 1 is a schematic representation of the present utility model.
Accompanying drawing 2 is an accompanying drawing 1A-A sectional drawing.
