Abstract
The utility model discloses a highly positioned fan on an oilless air compressor. The highly positioned fan on the oilless air compressor comprises a fan body; fan blades are evenly distributed on the fan body; each fan blade is in the shape of a curved surface; the highly positioned fan on the oilless air compressor also comprises a live shaft and locating pins; the live shaft is fixedly arranged in the center part of the fan body; the locating pins are fixedly arranged on the bottom face of the inner end of the fan body; clamping grooves clamped onto a power output shaft are formed in the live shaft. The highly positioned fan on the oilless air compressor disclosed by the utility model has the advantages that the structure is simple; the four clamping grooves in the live shaft can be effectively clamped onto the power output shaft, and thus, force borne by the highly positioned fan can be more uniform during working, and the looseness phenomenon cannot occur after the highly positioned fan is used for a long time; the locating pins and be compactly spliced and fixed into pin holes in the power output shaft, so that the live shaft is more stable when working, and the service life of the live shaft is prolonged.
Description
Technical field
The utility model belongs to air compressor technical field, especially relates to the high positioning fan on a kind of oilless air compressor.
Background technique
Air compressor is the basic product of the modernization of industry, and it is mainly the device that mechanical energy is converted to gas pressure energy, is compressed-air actuated pressure generator.Fan is as the critical piece on air compressor, and it mainly waves loose to the heat in air compressor, prevents that temperature is too high and causes device damage.Fan on existing air compressor and pto＝power take-off are due to the not compact unbalance stress that causes in location, after being used, permanent connection there will be loosening phenomenon, the middle noise of so not only working is louder, and can affect stability and the Security of work, after permanent, cause the damage of equipment, be therefore necessary to be improved.
Summary of the invention
The purpose of this utility model is the deficiency existing for above-mentioned prior art, provide a kind of simple in structure that, easy to use and connect after high positioning fan on the oilless air compressor that can firmly work.
To achieve these goals, the technological scheme that the utility model adopts is: the high positioning fan on a kind of oilless air compressor, comprise fan body, and on described fan body, be evenly distributed with flabellum, described flabellum is curve form; It also comprises rotatingshaft and positioning pin column, and described rotatingshaft is fixed on the central part of fan body; Described positioning pin column is fixedly installed on the inner bottom surface of fan body; On described rotatingshaft, offer the buckling groove with pto＝power take-off clamping.
Described positioning pin column is four, and it is evenly distributed on the inner bottom surface of fan body.
Described buckling groove is four, and it is evenly distributed on rotatingshaft.
Described flabellum is nine, and it is evenly distributed on the circumferential surface of fan body.
Adopt after said structure, the advantage that compared to the prior art the utility model had is: of the present utility model simple in structure, four buckling grooves on rotatingshaft can be effectively and pto＝power take-off carry out clamping, stressed more even so at work, after long-time use, also there will not be loosening phenomenon; Positioning pin column can with pto＝power take-off on pin-and-hole compact peg graft fixingly, make rotatingshaft more stable in the time of work, extend its working life.
Brief description of the drawings
Fig. 1 is structural representation of the present utility model.
Embodiment
The following stated is only preferred embodiment of the present utility model, does not therefore limit protection domain of the present utility model, below in conjunction with drawings and Examples, the utility model is further illustrated.
Embodiment, as shown in Figure 1: the high positioning fan on a kind of oilless air compressor, comprises fan body 10, rotatingshaft 20 and positioning pin column 30.On described fan body 10, be evenly distributed with flabellum 11, flabellum 11 is nine and for curve form, it is evenly distributed on the circumferential surface of fan body 10, can drive flabellum 11 to rotate by the rotation of fan body 10.Described rotatingshaft 20 is fixed on the central part of fan body 10, is coordinated and drives fan body 10 to rotate with the power output on air compressor by it.On described rotatingshaft 20, offer and the buckling groove 21 of pto＝power take-off clamping, buckling groove 21 is four, and it is evenly distributed on rotatingshaft 20; Buckling groove 21 with pto＝power take-off clamping after can allow the utility model stressed evenly, there will not be loosening phenomenon, make work more stable.Described positioning pin column 30 is four, and it is evenly distributed on the inner bottom surface of fan body 10; Positioning pin column 30 can with pto＝power take-off on pin-and-hole compact peg graft fixingly, make rotatingshaft more stable in the time of work, extend its working life.
