Abstract
The utility model relates to a ventilating machine which is used for an air conditioning system, composed of a shell body (7), an impeller (1), a motor with an inner rotor (4), a supporting bracket (8a) and a supporting bracket (8b). The utility model is mainly characterized in that the supporting brackets (8a) and (8b) are respectively fixed on both sides of the shell body (7); the machine shell of the motor with an inner rotor (4) and a bearing (2) are respectively fixed on the supporting brackets; a connecting flange (3) is fixedly sheathed with rotating shaft of the motor with an inner rotor (4); the impeller (1) and the connecting flange (3) are connected into one body. The utility model has the advantages of compact structure, stable operation, low noise and low cost, and is suitable for the industries of air-conditioning, purifying, freezing, etc.
Description
The utility model relates to a kind of ventilating machinary that is used for air-conditioning system.
The ventilator that is used for the indoor large air-conditioning system at present mainly contains two kinds.A kind of is outer transmission ventilator, and motor mounting is in the ventilator outside, and by the wheel rotation in coupling or the belt pulley drive ventilator, though this ventilator is made and maintenance is all more convenient, volume is big, structure is not compact.Another kind is the external rotor ventilator, use external rotor electric machine, motor to be installed in the ventilator housing, the mid-game of fan impeller with the center flange of motor housing, connect, many, the weight of moving element is greatly though this ventilator compact structure, volume are little, galloping, noise is big, manufacture cost is high.
The purpose of this utility model is the shortcoming that overcomes above-mentioned prior art, provides a kind of compact structure, volume is little, running is steady, noise is little, two air intake centrifugal ventilators of low cost of manufacture.
The main technical schemes that the utility model adopts is in the both sides of centrifugal blower housing (7) support (8a), (8b) to be set respectively, the casing of inner rotor motor (4) and bearing (2) be separately fixed at support (8a) and (8b) on, fixedly an adpting flange of suit (3), impeller (1) and adpting flange (3) are connected into one on the rotatingshaft of inner rotor motor (4).Inner rotor motor (4) work by adpting flange (3), makes impeller (1) high speed rotating, and air sucks housing (7) from air intake circle (6a), (6b), and swiftly flowing air is discharged from the relief opening of housing (7).
Work drive motor of the present utility model is installed in the enclosure interior of ventilator, and compact structure, volume is little and adopt inner rotor motor, moving element is in light weight, running is steady, noise is little, low cost of manufacture, be suitable for air-conditioning, purification, industry extensive use such as freezing.
Fig. 1 is the utility model plan view
Fig. 2 is the A-A sectional view of Fig. 1
Fig. 3 is the utility model plan view
Fig. 4 is for adopting mid-game adpting flange embodiment's structural representation.
Below in conjunction with drawings and Examples the utility model is further described:
Referring to Fig. 1, Fig. 2, housing of the present utility model (1) is the volute housing, respectively there is an air intake circle (6a) both sides, (6b), support (8a), (8b) weld or be riveted on the both sides of housing (1), a concavo-convex adpting flange or retainer ring (5) can be set on the support (8a), shell with fixed motor (4), bearing (2) is fixed on the support (8b), the adpting flange (3) that is fixedly set on the rotatingshaft of motor (4) is the bowl-type flange, also can be that mid-game adpting flange (referring to accompanying drawing 4) adpting flange (3) is fixedly connected with impeller (1).Impeller (1) can be the prismatic blade radial impeller.
Claims (2)
1, a kind of two air intake centrifugal ventilators of forming by housing (7), air intake circle (6a), (6b) support (8a), (8b) impeller (1) and inner rotor motor (4) etc., it is characterized by the both sides that support (8a), (8b) are separately fixed at housing (1), the casing of inner rotor motor (4) and bearing (2) are separately fixed on support (8a), (8b), adpting flange (3) is fixedly set on the rotatingshaft of inner rotor motor (4), and impeller (1) and adpting flange (3) link into an integrated entity.
2, by described pair of air intake centrifugal ventilator of claim 1, it is characterized by adpting flange (3) can be a bowl type flange, or the mid-game flange.
