Abstract
The utility model relates to a novel ceiling fan, comprising blades and a ceiling-fan motor. The shell of the ceiling-fan motor is composed of an upper shell and a lower shell which are directly punched forming and are provided with bearing chambers in the center. The utility model can ensure the coaxiality of the inner hole of the bearing in the shell and the rabbet of the shell by the punch processing of dies. Compared with the existing structure, the utility model has the advantages of the simplification of process technology, convenient assembly, and easy guarantee of precision. So waste products are reduced, work efficiency is improved, and cost is reduced.
Description
The utility model relates to the ceiling fan structure technology, particularly a kind of direct new structure ceiling fan by upper and lower shell impact briquetting bearing chamber.
Existing ceiling-fan motor upper and lower shell and bearing chamber are divided into two parts, make bearing chamber and housing be connected into one by welding procedure.Guarantee the coaxality of bearing chamber endoporus and housing seam through milling process.This structure length consuming time, efficient is low, be prone to waste product.
The purpose of this utility model is to provide a kind of simple in structure, assembling easily and the new structure ceiling fan that easily guarantees of precision for overcoming above-mentioned deficiency.
A kind of new structure ceiling fan comprises flabellum and ceiling-fan motor, and this ceiling-fan motor housing is made of the upper and lower shell of direct stamping forming central zone bearing chamber.Guarantee the coaxality of indoor hole of housing bearing and housing seam by mould.Required in the past welding, milling process step have been cancelled.
Advantage of the present utility model is that tube changed processing technology, and convenient for assembly and precision easily guarantees, thereby, significantly reduced reject rate, improved manufacturing efficiency, reduced cost of production.
Fig. 1 is the utility model ceiling-fan motor structural representation.
Below by embodiment the utility model is further elaborated.
At first, as shown in Figure 1, with the upper casing 4 and the lower casing 2 of the direct impact briquetting band of steel plate bearing chamber.At the indoor oil-impregnated bearing 1 of loading onto of lower casing 2 centre bearings, at its peripheral assembly upper rotor part 3.Fan motor main shaft 9 middle parts embed stator 5.Bearing 6 is packed in the bearing chamber of upper casing 4, and this assembly assembly positions with 10 pairs of bearings 6 of jump ring on main shaft 9 tops again, with screw 8 upper casing pressing plate 7 is tightened in upper casing 4 central authorities.Above-mentioned assembly parts are inserted in the lower casing 2, and be inserted in the oil-impregnated bearing 1 electric machine main shaft 9 lower ends, and at this moment, the upper and lower shell assembly is in seam 11 place's locating engagement, and with screw upper casing 4 is fixed tightly on the rotor 3, promptly finishes the assembling work of this new structure ceiling fan.Because upper casing 4 is the standarized components that come out by die stamping with lower casing 2, so assembling accurately can guarantee the coaxality of indoor hole of housing bearing and housing seam 11 fully.Thereby, can improve work efficiency, reduce waste product.
