Abstract
The utility model relates to a novel wheel hub structure of a ventilator impeller. The wheel hub structure is added in the impeller through a central disc, a shaft sleeve is fastened on a wheel hub, and a shell is installed on a motor and can extend into the wheel hub to reduce the occupied area of exposing the motor shell. The super-thin ventilator can be realized by utilizing a common motor. The ventilator occupies less space and has large blast volume and high efficiency, the motor has low manufacturing cost and convenient maintenance and bearing exchange and long service life, the impeller is installed conveniently and the motor degree of protection is effectively improved. The wheel hub structure is suitable for super-thin air conditioning units, such as underground railways, passenger cars, and the like.
Description
Technical field
The utility model relates to a kind of ventilator, especially a kind of novel ventilated machine impeller hub structure.
Background technique
The blade wheel structure kind of ventilator is a lot, from common single face intake air impeller to double-faced ventilated impeller and there is not a shell transmission impeller etc., the blade wheel structure technological improvement of ventilator at present a lot, change the external rotor electric machine blade wheel structure in order to save the space blade wheel structure, have motor manufacture cost height, electrical machmary maintenance and replacing bearing difficulty, motor is short working life, problems such as security level is low, especially in the situation of ultra-thin air-conditioning units such as subway, passenger vehicle, it is particularly important that the size that ventilator takes up room seems.
Summary of the invention
The purpose of this utility model is a kind of compact structure of design, novel ventilated machine impeller hub structure little, easy for installation takes up room.The technical solution of the utility model is so to realize:
Novel ventilated machine impeller hub structure comprises impeller, axle sleeve, motor, has set up a wheel hub in impeller, and axle sleeve is located at the top of wheel hub, and 1/6～1/4 of the upper end of motor is located in the wheel hub.
As preferably, described wheel hub is connected in the impeller by bolt.
The fan impeller wheel hub structure of the utility model design, impeller increases wheel hub structure by mid-game, axle sleeve is fastened on the wheel hub, and motor is installed housing and can be stretched into and reduce electric machine casing in the wheel hub and expose and take up room, and adopts common electric machine can realize ultrathin blower fan, make blower fan take up room little, air quantity is big, efficient is high, the motor low cost of manufacture makes things convenient for impeller to install, and electrical machmary maintenance and bearing replacing are convenient, effectively improve the motor security level, make motor with characteristics such as the life-span are long.Be applicable to that ultra-thin air-conditioning unit such as subway, passenger vehicle uses.
Description of drawings
Accompanying drawing is a kind of structural representation of the present utility model.
Embodiment
Below in conjunction with accompanying drawing,, the technical solution of the utility model is described in further detail by embodiment.
Embodiment: with reference to the accompanying drawings, novel ventilated machine impeller hub structure comprises impeller 1, axle sleeve 3, motor 4, has set up a wheel hub 2 in impeller 1, and described wheel hub 2 is connected in the impeller 1 by bolt.Axle sleeve 3 is located at the top of wheel hub 2, and 1/5 of the upper end of motor 4 is located in the wheel hub 2.
During installation, axle sleeve 3 is inserted in wheel hub 2 mounting hole bolton; By the mid-game of impeller 1 and wheel hub 2 flange edges the installing and locating hole being set aligns and uses bolton; The impeller assembly of being made up of axle sleeve 3, wheel hub 2, impeller 1 is installed to motor shaft and motor 4 housings is stretched into reduce in the wheel hub 2 electric machine casing to expose to take up room, adopt common electric machine can realize ultrathin blower fan.
