Abstract
The utility model provides a rotary fan blade with high stability, comprising a fan blade and a beam barrel, wherein the beam barrel is arranged in the middle of the fan blade; inner holes are arranged at two ends of the beam barrel; and a plastic layer with certain thickness is adhered on the inner wall of the inner hole, is made of engineering plastics subjected to injection molding by a mould for once, and has higher mechanical strength. In the rotary fan blade with high stability, the fan blade and the beam barrel have an integral structure, the diameter of the inner hole of the beam barrel is larger than a preset value, and then the plastic layer is injected onto the inner wall of the inner hole of the beam barrel by injection molding, thereby obtaining roll balls with preset size; and then, the roll balls are arranged on the plastic layers of the inner holes of the beam barrel and directly contacted with the plastic layers, so that the axes of the roll balls can be coincided, therefore, the rotating stability of the fan blade can be ensured. The rotary fan blade with high stability is characterized in that processing and manufacturing are simple, the cost is low, and the rotation has high stability, and has a wide application prospect.
Description
Technical field
The utility model relates to a kind of fans, especially a kind of easy machine shaping, and have the higher stationarity and the fans of running accuracy, belong to radiating device technical field.
Background technique
Fan (rotor fan) is to be installed on the axle of rotor one or both ends, agitates the mechanical component of gas cooling generator windings and iron core etc., is widely used in to produce and various fields in life.Existing fans comprises flabellum and the beam barrel that is positioned at the flabellum middle part, and the beam barrel middle part has the endoporus that rotating shaft is installed, and general, flabellum is made by engineering plastics, and the material of beam barrel is metal often.When rotating shaft is installed, two kinds of methods are arranged usually, a kind of is to be provided with one to have high-intensity metal ring in the endoporus of beam barrel, ball promptly is against on the metal ring, this installation method is had relatively high expectations to the rotating cylinder material, and also higher to the requirement of machining accuracy, the cost of product is very high; Another kind method is to be polished on mould in the two ends of beam barrel and change the hole, reaches predetermined aperture, then ball is installed in the two ends of beam barrel; This installation method is less demanding to the beam barrel material, processing cost is lower, but owing to when polishing of beam barrel two ends and commentaries on classics hole, flabellum need be overturn, the axis in hole is changeed on same straight line in the so just very difficult beam barrel two ends that guarantee, therefore the installation of ball just inevitably can occur not point-blank, during high speed rotating, the vibration of flabellum will occur, noise is bigger, the stationarity and the running accuracy of flabellum are relatively poor, and therefore shorten working life.
Summary of the invention
The utility model promptly is at the above-mentioned defective that exists in fans at present, provide a kind of processing and fabricating easy, and can guarantee the endoporus dead in line of flabellum beam barrel two ends, thereby resulting fans has advantages of higher stability and running accuracy.
Specifically, the fans of high stable rotation described in the utility model is characterized in that: described fans comprises flabellum and is positioned at the beam barrel at flabellum middle part that the beam barrel two ends have endoporus, have and have certain thickness plastic layer on the inwall of endoporus.
The fans of described high stable rotation is characterized in that: described plastic layer has higher mechanical strength for the engineering plastics by the mould single injection-molded.
The fans of described high stable rotation, it is characterized in that: the material of described beam barrel comprises metal.
The fans of described high stable rotation is characterized in that: the equal diameters of described beam barrel two ends endoporus or do not wait.
The fans of described high stable rotation is characterized in that: the thickness of described plastic layer at endoporus place, beam barrel two ends equates or does not wait.
The fans of high stable rotation described in the utility model, in course of working, structure earlier is connected as a single entity flabellum and beam barrel machine shaping, the diameter of beam barrel endoporus is greater than predetermined size, then plastic layer is injected prefabricated mould, on the inwall of plastic layer die casting attached to the beam barrel endoporus, the radius that thickness equals present beam barrel endoporus deducts the radius of the beam barrel endoporus of wishing to get; Because the making of mould can be very accurate, dimensional accuracy can be controlled in the minimum tolerance, by hole and polishing are changeed in the beam barrel two ends, more can reach default size as compared with the past.When at the beam barrel two ends ball being installed like this, ball directly contacts plastic layer, can make the dead in line of two balls like this, has guaranteed stability of rotation.
The fans of described high stable rotation has following advantage:
1, simple and practical, convenient processing and manufacture;
2, the processing and fabricating of mould can reach very high validity, has therefore guaranteed the high stability of fans rotation;
3, less demanding, with low cost to the fans material.
Description of drawings
Fig. 1 is the utility model embodiment's a perspective view;
Fig. 2 is the utility model embodiment's a cross-sectional view;
Wherein, 1 is that flabellum, 2 is that beam barrel, 20 is that endoporus, 3 is plastic layer.
Embodiment
Describe below in conjunction with the fans of accompanying drawing high stable rotation described in the utility model; purpose is better to understand technology contents described in the utility model for the public; rather than to the restriction of described technology contents; in fact; in invention spirit of the present utility model; to the improvement of described fans structure, comprise the change of size, shape and material etc., all within the utility model technological scheme required for protection to appropriate section.
As depicted in figs. 1 and 2, the fans of high stable rotation described in the utility model, comprise flabellum 1 and the beam barrel 2 that is positioned at flabellum 1 middle part, beam barrel 2 two ends have endoporus 20, on the inwall of endoporus 20, have and have certain thickness plastic layer 3, described plastic layer 3 is the engineering plastics by the mould single injection-molded, has higher mechanical strength.
The equal diameters of described beam barrel two ends endoporus or do not wait, the thickness of plastic layer at endoporus place, beam barrel two ends equates or does not wait.
The fans of high stable rotation described in the utility model, flabellum and beam barrel are structure as a whole, the diameter of beam barrel endoporus is greater than predetermined size, plastic layer is injected on the inwall of beam barrel endoporus by injection moulding then, obtain the size of predetermined ball, then ball is installed on the plastic layer of beam barrel endoporus, ball directly contacts plastic layer, can make the dead in line of two balls like this, guarantee the fans stability of rotation.
