Description

Step of metal hub

Technical Field

The utility model relates to a step, in particular to metal wheel hub's step belongs to step technical field.

Background

The inner wind wheel component is widely used in various household appliance brands of air conditioners and automobile air conditioners, and the lockers are essential important components for matching of fan blades and motor connecting sections for household, commercial and automobile air conditioners, a wind film machine, a wind blowing fan and the like. Currently used paces have the following problems:

1. the original product needs to be made into a plastic hub by injection molding on a round framework of the step, and compared with the complex working procedures, the efficiency is low;

2. the product is suitable for the wind film machine, and the wind film machine has long service time and high frequency, so that the plastic fan blade is easy to break down particularly in winter in the north;

3. the main rubber is too thin, and the noise is high; the rubber end surface is a horizontal plane, and the strength is not large enough.

SUMMERY OF THE UTILITY MODEL

The utility model aims at providing a metal wheel hub's step to among the above-mentioned prior art, numerous and diverse inefficiency of process, the defect that the plastics fan blade easily broke down, can simple to operate, stable in structure's purpose.

In order to realize the purpose, the utility model adopts the technical scheme that: a metal hub step, named as a step for short, is matched with fan blades for use, and comprises a main body; the main body material is rubber; the step also comprises an aluminum core and a circular hub; the upper part of the aluminum core is wrapped in the center of the main body and fixedly connected with the main body; a motor shaft hole is formed in the aluminum core; the circular hub is a metal hub or a circular ring, and an inner ring of the circular hub is embedded in the main body and fixedly connected with the main body; and a plurality of fan blade mounting grooves are uniformly distributed on the periphery of the outer ring of the circular hub.

And the side surface of the lower part of the aluminum core is provided with a screw hole. After the shaft of the motor is inserted into the shaft hole of the motor, the shaft is fixed by a screw through the screw hole.

The metal hub is an aluminum hub.

The main part includes 2 terminal surfaces, and the contained angle of terminal surface and horizontal plane is 1 degree.

Compared with the prior art, the beneficial effects of the utility model are that:

1. the original circular framework is combined with the structural characteristics of a hub to design a circular metal hub in a brand new way, and the fan blades are embedded in the outer ring fan blade mounting grooves in the direction and can become through-flow fan blades after being reinforced; the process is simple;

2. through the structural adjustment to the image colloid, thicken colloid thickness and adopt two-sided inclination design, both increased the intensity of product and promoted the shock attenuation effect again.
