Abstract
The utility model discloses an angle regulation structure of a fan blade for a propeller type fan. The angle regulation structure comprises the fan blade and a hub, which are fixed together; the fan blade is mounted on the hub through a fixing ring and a bolt; and wedge-shaped gaskets are respectively padded between the fan blade and the fixing ring as well as between fitting surfaces of the fan blade and the hub. According to the angle regulation structure, the fan blade is mounted on the hub through the fixing ring and the bolt; the wedge-shaped gaskets are respectively padded between the fan blade and the fixing ring as well as between the fan blade and the fitting surface of the hub; one surfaces of the wedge-shaped gaskets are planes; and the other surfaces of the wedge-shaped gaskets are circular-arc surfaces. After the mounting of the fan is completed, the angle of the fan blade can be regulated through adjusting the positions of the wedge-shaped gaskets, so that an air pressure and an air quantity are regulated conveniently.
Description
Technical field
The utility model relates to a kind of fan leaf angle adjustment mechanism for propeller type fan.
Background technique
The propeller type fan of traditional design, its fan leaf and wheel hub are aluminium alloy castings or are welded into as a whole.But there is following shortcoming in this structure:
After finishing, the fan manufacturing can't regulate easily blast and air quantity.
Summary of the invention
The utility model purpose is for the existing deficiency of prior art, and a kind of fan leaf angle adjustment mechanism for propeller type fan is provided, and it can pass through to regulate the angle of fan leaf after the propeller type fan manufacturing is finished, thereby regulates blast and air quantity.
In order to solve these problems of the prior art, the technological scheme that the utility model provides is:
A kind of fan leaf angle adjustment mechanism for propeller type fan, comprise the fan leaf and the wheel hub that are fixed together, described fan leaf is installed on the described wheel hub by retaining ring, bolt, is lined with a taperliner at the faying surface among of fan leaf and retaining ring, fan leaf and wheel hub.
As optimization, the one side of described taperliner is the plane, and another side is arc surface.In addition, in the middle of described taperliner, be provided with the long-round-shape through hole, be used for the coupling shaft of taperliner cross-under at connection fan leaf and wheel hub is convenient to the fixing of taperliner.
As optimization, described fan leaf, wheel hub are absolute construction.
Than solution of the prior art, the utility model advantage is:
The utility model has been described a kind of fan leaf angle adjustment mechanism for propeller type fan.Wherein, fan leaf and wheel hub are independent manufacturing, then fan leaf are installed on the wheel hub by retaining ring, bolt.The utility model is at taperliner of faying surface among pad of fan leaf and retaining ring, fan leaf and wheel hub, and the one side of taperliner is the plane, and the another side of taperliner is arc surface.After the fan installation, the angle that can regulate fan leaf by the position of adjusting taperliner, thus regulate easily blast and air quantity.
Description of drawings
Below in conjunction with drawings and Examples the utility model is further described:
Fig. 1 is the overall structure schematic representation that the utility model embodiment describes the fan leaf angle adjustment mechanism;
Fig. 2 is the structural representation of taperliner among the utility model embodiment;
Wherein: 1, fan leaf; 2, wheel hub; 3, retaining ring; 4, taperliner.
Embodiment
Below in conjunction with specific embodiment such scheme is described further.Should be understood that these embodiments are not limited to limit the scope of the invention for explanation the present invention.The implementation condition that adopts among the embodiment can be done further adjustment according to the condition of concrete producer, and not marked implementation condition is generally the condition in the normal experiment.
Embodiment:
Present embodiment has been described a kind of fan leaf angle adjustment mechanism for propeller type fan, its structure as shown in Figure 1, comprise the fan leaf 1 and the wheel hub 2 that are fixed together, described fan leaf 1, wheel hub 2 are absolute construction, described fan leaf 1 is installed on the described wheel hub 2 by retaining ring 3, bolt, is lined with a taperliner 4 at fan leaf 1 and retaining ring 3, fan leaf 1 with the faying surface among of wheel hub 2.
The shape of taperliner 4 as shown in Figure 2, the one side of described taperliner 4 is the plane, another side is arc surface.In addition, in the middle of described taperliner 4, be provided with the long-round-shape through hole, be used for the coupling shaft of taperliner 4 cross-under at connection fan leaf 1 and wheel hub 2 is convenient to the fixing of taperliner 4.
Above-mentioned example only is explanation technical conceive of the present invention and characteristics, and its purpose is to allow the people who is familiar with technique can understand content of the present invention and according to this enforcement, can not limit protection scope of the present invention with this.All equivalent transformations that Spirit Essence is done according to the present invention or modification all should be encompassed within protection scope of the present invention.
