Abstract

The utility model relates to a dual-suction centrifugal fan motor support, which comprises supporting arms and a shaft sleeve mounted on a motor shaft. The motor support has the following characteristics: the support also comprises a vibration-reducing rubber sleeve and an outer sleeve, wherein the vibration-reducing rubber sleeve is sleeved on and fixed with the shaft sleeve, the outer sleeve is sleeved on and fixed with the vibration-reducing rubber sleeve, and supports are arranged on the outside of the outer sleeve, and are connected with the supporting arms. Since one end of the supporting arm is isolated from the shaft sleeve by the vibration-reducing rubber, the vibration-reducing rubber can absorb the vibration caused by the rotation of a fan wheel driven by a motor, consequently, the resonant vibration caused by the vibration transmitted to the support and onward to a volute housing is reduced, and the noise caused by the resonant vibration is reduced.

Description

Double suction is gone into the centrifugal fan electric machine support

Technical field

The utility model relates to a kind of double suction and goes into the centrifugal fan electric machine support.

Background technique

Traditional double suction is gone into the centrifugal fan electric machine support, and as shown in Figure 1, 2, what comprise support arm (1) and connect each support arm directly is fixed on axle sleeve (2) on the machine shaft (3).In use, motor (4) drive wind wheel rotates caused vibration and passes to support by machine shaft, passes to spiral case by support again, causes complete machine resonance, produces bigger noise.

The model utility content

The utility model is to overcome the deficiencies in the prior art and provide a kind of can reduce to vibrate and the double suction of noise is gone into the centrifugal fan electric machine support.

In order to achieve the above object, the utility model is achieved in that it is that a kind of double suction is gone into the centrifugal fan electric machine support, comprises support arm and is installed in axle sleeve on the motor shaft; It is characterized in that: also comprise be enclosed within axle sleeve outer and with its fixing vibration isolation rubber cover; Also jacket be located at vibration isolation rubber cover outer and with its fixing overcoat, at the overcoat peripheral hardware support is arranged, support is fixedlyed connected with support arm.

Also comprise vibration isolation rubber cover and the fixing taper key of axle sleeve, on taper key, have second circular groove, on the axle sleeve endoporus, have the upper half-round slot that matches with second circular groove; Also comprise tapping screw, tapping screw is located in the upper and lower half slot vibration isolation rubber cover and axle sleeve is fixed.

Put at described vibration isolation rubber and to be provided with three grooves, be provided with three inwardly protruded boss that match with groove on the coat.

The utility model advantage compared with prior art is, because an end and the axle sleeve of support arm are isolated with vibration isolation rubber, vibration isolation rubber can absorb the vibration that the rotation of driven by motor wind wheel is brought, thereby reduce this vibration and pass to support, pass to the resonance that spiral case causes by support again, reduce because the noise that resonance causes.

Embodiment

Below in conjunction with drawings and Examples the utility model is further described;

Shown in Fig. 3 to 6, it is that a kind of double suction is gone into the centrifugal fan electric machine support, comprises support arm 1 and is installed in axle sleeve 2 on the motor shaft 3; Characteristics of the present utility model are: also comprise being enclosed within outside the axle sleeve and with its fixing vibration isolation rubber and overlap 5; Also jacket be located at vibration isolation rubber cover outer and with its fixing overcoat 8, at the overcoat peripheral hardware support 81 is arranged, support is fixedlyed connected with support arm 1.

In the present embodiment, also comprise the taper key 7 that vibration isolation rubber cover 5 and axle sleeve 2 are fixed, on taper key, have second circular groove 71, on the axle sleeve endoporus, have the upper half-round slot 21 that matches with second circular groove; Also comprise tapping screw 6, tapping screw is located in the upper and lower half slot, thereby vibration isolation rubber cover and axle sleeve are fixed.On vibration isolation rubber cover 5, be provided with three grooves 51, on overcoat 8, be provided with three inwardly protruded boss 82 that match with groove, thereby prevent that the relative vibration isolation rubber of overcoat radially or move axially, be provided with hole 83 on the coat, can mounting screw in the hole, vibration isolation rubber further is fixed in the overcoat.

During use, motor 4 drives the wind wheels rotation, and wind wheel drives the air-flow that the air rotation produces, and after spiral case and snail tongue are compiled, derives from the exhaust outlet direction, and the vibration that motor produced is absorbed by vibration isolation rubber 5, has reduced noise accordingly.
