Abstract
The utility model discloses a kind of fan shaft, it comprises circular axis body, it is characterized in that: on the side of described axis body, vertically inwardly offer several box-shaped grooves, in described groove, be provided with several projections, the inside of described axis body is provided with an internal layer, and described internal layer surface is provided with some screw threads.Fan shaft of the present utility model vertically inwardly offers several box-shaped grooves for placing the transmission instrument matching with it on the side of axis body, groove can increase friction and driving force, the projection arranging in groove has increased frictional force, makes transmission instrument be difficult for landing; The inside of axis body is provided with an internal layer, and internal layer surface is provided with some screw threads also for increasing frictional force, there will not be the phenomenon such as skid.The utlity model has simple in structure, long service life, low cost and other advantages.
Description
Technical field
The utility model relates to a kind of auxiliary component, especially a kind of fan shaft.
Background technique
As everyone knows; fan shaft is the vitals of connecting fan wind wing and base plate; at present; more or less also there are some problems in the manufacture of fan shaft; as high in manufacture cost; accuracy of manufacturing is not high, and fan shaft because the variation of frictional force usually there will be the phenomenon such as skid, has affected working efficiency in operation process.
Summary of the invention
In order to overcome the problems referred to above, the utility model provides a kind of fan shaft of simple in structure, long service life.
The technical solution of the utility model is to provide a kind of fan shaft, it comprises circular axis body, it is characterized in that: on the side of described axis body, vertically inwardly offer several box-shaped grooves, in described groove, be provided with several projections, the inside of described axis body is provided with an internal layer, and described internal layer surface is provided with some screw threads.
In preferred embodiment of the utility model, a kind of fan shaft further comprises that described axis body simultaneously stretches out and forms an extension part, and the seamed edge of described extension part and the side of described axis body form a chamfering.
In preferred embodiment of the utility model, a kind of fan shaft further comprises that described groove is at least provided with four, and the angle forming between described groove is made as 90 degree.
In preferred embodiment of the utility model, a kind of fan shaft further comprises that the length of described groove is arranged between 6cm-8cm.
In preferred embodiment of the utility model, a kind of fan shaft further comprises the setting that is formed in one of described axis body and described internal layer.
In preferred embodiment of the utility model, a kind of fan shaft further comprises that described internal layer adopts chromatize just to make.
Fan shaft of the present utility model vertically inwardly offers several box-shaped grooves for placing the transmission instrument matching with it on the side of axis body, groove can increase friction and driving force, the projection arranging in groove has increased frictional force, makes transmission instrument be difficult for landing; The inside of axis body is provided with an internal layer, and internal layer surface is provided with some screw threads also for increasing frictional force, there will not be the phenomenon such as skid.The utlity model has simple in structure, long service life, low cost and other advantages.

Fig. 2 is the side structure schematic diagram of a kind of fan shaft of the utility model most preferred embodiment.
Embodiment
Below embodiment of the present utility model is described in further detail.
As depicted in figs. 1 and 2, a kind of fan shaft of the present utility model, it comprises circular axis body 1, on the side of axis body 1, vertically inwardly offer several box-shaped grooves 2, in groove 2, be provided with several projections 3, the inside of axis body 1 is provided with an internal layer 4, and internal layer 4 surfaces are provided with some screw threads (not shown).
Axis body 1 one side stretches out and forms an extension part 5, and the side of the seamed edge of extension part 5 and axis body 1 forms a chamfering 6; Groove 2 is at least provided with four, and the present embodiment is provided with four grooves 2, and the angle forming between groove 2 is made as 90 degree; The length of groove 2 is arranged between 6cm-8cm; The setting that is formed in one of axis body 1 and internal layer 4; Internal layer 4 adopts chromatize just to make.
Fan shaft of the present utility model vertically inwardly offers several box-shaped grooves 2 for placing the transmission instrument matching with it on the side of axis body 1, groove 2 can increase friction and driving force, the projection 3 of groove 2 interior settings has increased frictional force, makes transmission instrument be difficult for landing; The inside of axis body 1 is provided with an internal layer 4, and internal layer 4 surfaces are provided with some screw threads also for increasing frictional force, there will not be the phenomenon such as skid; Axis body 1 one side stretches out and forms the thickness that an extension part 5 has increased axis body, four grooves 2 that at least arrange have guaranteed the stationarity of transmission, 90 degree at a distance of from groove 2 more stable, the length of groove 2 is arranged between 6cm-8cm more stable with coordinating of transmission instrument, perfection; Axis body 1 and the internal layer 4 of one-body molded setting make fan shaft more firm, and not fragile, the internal layer 4 that chromatize has just been made has increased wear resistance, more durable.
Above embodiment is only the utility model a kind of mode of execution wherein, and it describes comparatively concrete and detailed, but can not therefore be interpreted as the restriction to the utility model the scope of the claims.It should be pointed out that for the person of ordinary skill of the art, without departing from the concept of the premise utility, can also make some distortion and improvement, these all belong to protection domain of the present utility model.Therefore, the protection domain of the utility model patent should be as the criterion with claims.
