Abstract
The utility model discloses a shaft core for a cabinet type air-conditioning fan, which comprises a barrel-shaped framework. The barrel-shaped framework comprises an inner framework, an outer framework and a rubber ring sleeve integrally vulcanized between the inner framework and the outer framework; a ladder for causing one end of an inner hole to be D-shaped is arranged in the inner hole of the inner framework; a motor main shaft matched with the inner hole of the inner framework is mounted in the inner hole of the inner framework; the surface of the outer framework adopts a hatching knurling structure, and an excircle of the outer framework is fixedly connected with the fan. The utility model reduces the vibration and the noise generated by the fan during the high-speed rotation through the rubber damping property.
Description
Technical field:
The utility model relates generally to the component that a kind of cabinet air-conditioner fan is connected with motor, relates in particular to a kind of cabinet air-conditioner fan axle core.
Background technique:
In the market, cabinet air-conditioner fan and motor connected element are complete single metal frame structures, and when this Placement can cause cabinet air-conditioner work, occurring vibrations generation noise in the fan running process can't eliminate.
The model utility content:
The purpose of model utility is exactly in order to remedy the defective of prior art, has improved a kind of cabinet air-conditioner fan and has solved fan with the axle core occurs shaking the noise that is produced in operation process.
The utility model is achieved through the following technical solutions:
A kind of cabinet air-conditioner fan axle core, include inner frame, outer skeleton, it is characterized in that having between the described inside and outside skeleton rubber ring set of sulfuration one, be provided with the ladder that makes endoporus one end be D shape in the described inner frame endoporus, described outer skeleton outer surface is a roughened surface.
Described outer skeleton outer surface has hatching knurling to constitute roughened surface.
Described outer skeleton one end has the inside edge.
In the described inner frame endoporus electric machine main shaft with matching is installed.
The hatching knurling structure is adopted on described outer skeleton surface, helps increasing injection moulding all-in-one-piece fan join strength.
Its working principle is: fan is molded over the outer of outer skeleton and puts, and electric machine main shaft passes the endoporus of inner frame, and the D shape position of the D shape structure of inner frame endoporus and electric machine main shaft is combined together, and during machine operation, by D shape position position-limiting action, drives fan and rotates; By the damping capacity of rubber ring set, vibration and noise that fan produces have been reduced when high speed rotating.
The utility model has the advantages that:
The utlity model has simple in structure, good stability, adhesion strength height, reduced vibration and noise that fan produces when rotating.
Description of drawings:
Fig. 1 is a structural representation of the present utility model.
Fig. 2 is a graphics of the present utility model.
Embodiment:
A kind of cabinet air-conditioner fan axle core, include the rubber ring set 2 of sulfuration one between inner frame 3, outer skeleton 1 and inner frame 3 and the outer skeleton 1, be provided with the ladder that makes endoporus one end be D shape in inner frame 3 endoporus, electric machine main shaft 4 with matching is installed in inner frame 3 endoporus, the hatching knurling structure is adopted on outer skeleton 1 surface, and its cylindrical is fixedly connected on fan 5.
Claims (3)
