Description

A kind of integral framework

Technical field

The utility model relates to axial-flow leaf skeleton technical field, specially a kind of integral framework.

Background technique

Middle-size and small-size axial-flow leaf is mainly used on ventilation axial flow blower, due to Costco Wholesale and multi-size, Consistency is poor after generally existing processing, in intensity without corresponding technique guarantee it is weaker cause to load onto vibrate after fan blade it is larger, together When phenomena such as generating de-stabilise due to reasons in structure such as integral strengths in longtime running.

Utility model content

(1) the technical issues of solving

(2) technical solution

In order to achieve the above object, the utility model is achieved by the following technical programs: a kind of integral framework, including Frame body is provided with several blades assembly angle in the frame body, and blade assembly angle is around frame body center isogonism Degree setting, blade assembly angle are set as torsional angle shape, the beading of several spiral-lock balance weights are provided on blade assembly angle Item.

Preferably, the quantity at blade assembly angle is 3-4.

Preferably, the frame body further includes skeleton intermediate angle, and the skeleton intermediate angle is arranged in frame body Between, the skeleton intermediate angle is set as stretching shape.

Preferably, frame body further includes centre bore, and the centre bore is arranged at the axle center of frame body, the center Several female end notches are provided on the outer ring in hole, the female end notch is angularly arranged around frame body center.

Preferably, the quantity of the female end notch is 4.

Preferably, the frame body is integrally formed formula structure.

(3) beneficial effect

The utility model provides a kind of integral framework.Have it is following the utility model has the advantages that

1, the integral framework is designed by averaging type and guarantees consistency, and use is integrally formed, and integrated torsional angle increases intensity And use can property, reach compared with other axis stream skeletons in process structure, in cost of manufacture advantageously, can more be protected in intensity Noise decreases card instead simultaneously, increases operational reliability in long-term normal use.

2, skeleton is made into triangle or quadrangle, keeps the scope of application larger by the integral framework.

3, integral framework, by using impartial shallow stretching, greatly increasing skeleton integral strength intermediate angle part.

4, the integral framework makes twisting resistance when skeleton and axle sleeve riveted increase by the way that multiple female end notches are arranged By force, the tightness of fan blade axle sleeve and skeleton at runtime is increased.

5, the integral framework, by the way that beading item is arranged, can removing fan blade from, that balance need to be clamped on blade is time-consuming and have The hidden danger for the risk that falls off.

6, the integral framework, can according to different fan blade performance requirements carry out torsional angle forming, shape angles a 20 degree- It is selected between 45 degree.

Specific embodiment

The present invention is further elaborated below by drawings and examples.

As shown in figures 1 to 6: a kind of integral framework, including frame body 1, frame body 1 are integrally formed formula structure, adopt Go out corresponding respectively shape with integral type blanking, guarantee its homogeneity of product, several blades assembly angle 2 is provided in frame body 1, Blade assembly angle 2 is angularly arranged around 1 center of frame body, and blade assembly angle 2 is set as torsional angle shape, according to the different fan blades of matching Performance requirement carries out torsional angle forming, and shape angles a is generally selected between 20 degree of -45 degree, is guaranteed by averaging type design consistent Property, use is integrally formed, integrated torsional angle increase intensity and use can property, reach compared with other axis stream skeletons in process structure, In cost of manufacture advantageously, it more can guarantee in intensity while noise decrease instead, increase in long-term normal use Operational reliability.

It is provided with the beading item 3 of several spiral-lock balance weights on blade assembly angle 2, shallow beading, the number of beading item 3 are carried out at diagram In 3-8 root, depth uses amount in the mating different balance weight spiral-locks of 0.3-1.2mm, remove from many fan blades need to be clamped on blade it is flat Weigh hidden danger that is time-consuming and having the risk that falls off.

The quantity that blade assembles angle 2 is 3-4, can be made into triangle and quadrangle, matching fan blade diameter 400-660mm it Between, the scope of application is larger.

Frame body 1 further includes skeleton intermediate angle 4, and skeleton intermediate angle 4 is arranged in the centre of frame body 1, among skeleton Angle 4 is set as stretching shape, and 4 part of skeleton intermediate angle increases overall skeleton intensity using impartial shallow stretch, and shallow stretching depth is in 3- 6mm。

Frame body 1 further includes centre bore 5, and centre bore 5 is arranged at the axle center of frame body 1, on the outer ring of centre bore 5 Several female end notches 6 are provided with, female end notch 6 is angularly arranged around 1 center of frame body, and the quantity of female end notch 6 is 4, To reinforce twisting resistance when riveting with axle sleeve 7, increasing fan blade, axle sleeve 7 and the tightness of skeleton do not loosen at runtime.

Foundation embodiment described above is enlightenment, and through the above description, relevant staff completely can be not In the range of deviateing this invention thought, various changes and amendments are carried out.The technical scope of this invention is not limited to In the content on specification, it is necessary to determine the range of its protection according to scope of the claims.
