Abstract
The utility model discloses a groove type rotating shaft, comprising a shaft body made of a stainless steel material, wherein the outer surface of the shaft body is provided with an anti-rust layer, the inner surface of the shaft body is provided with a wearproof layer, a mounting hole is arranged in the center of the shaft body, the shaft body is provided with a plurality of fixing holes, the peripheral surface of the shaft body is provided with a plurality of grooves, the top areas of the grooves are larger than the bottom areas of the grooves, the longitudinal sections of the grooves are shaped like isosceles trapezoids, and the cross sections of the grooves are rectangular. The groove type rotating shaft is convenient to mount and good in driving stability and can be used as a driving wheel.
Description
Technical field
The utility model relates to a kind of rotating shaft, particularly a kind of groove type rotating shaft.
Background technique
Rotating shaft be that link product zero main part must be used, generally the axle that had not only born moment of flexure for rotation work but also born moment of torsion is called to rotating shaft.Common rotating shaft has: handset shaft; Notebook computer rotation shaft; Portable DVD player rotating shaft; The rotating shaft of LED desk lamp; LCD display rotating shaft; Vehicle-mounted rack shaft such as GPS etc.Rotating shaft wearing and tearing are plant issues common in axle using process, mainly that metallic character by axle causes: although metal hardness is high, but deformability is poor, shock resistance is poor, anti-fatigue performance is poor, therefore easily cause adhesive wear, abrasive wear, fatigue wear, fretting wear etc.The wearing and tearing of most axle class are difficult for discovering, and only occur machine high temperature, during the situation such as the amplitude of beating is large, abnormal sound, just can cause and discover, but while realizing to people, most of transmission shaft all worn and torn, thereby causes machine down.Existing rotating shaft does not have the function of using when driving wheel, and installs inconvenient.
Summary of the invention
The utility model is mainly to solve the existing technical problem of prior art, thereby provides a kind of easy for installation, can work as driving wheel and use, and drives the groove type rotating shaft of good stability.
Above-mentioned technical problem of the present utility model is mainly solved by following technical proposals:
A kind of groove type rotating shaft, comprise the axis body of being made by stainless steel material, the outer surface of described axis body is provided with resin layer, the internal surface of axis body is provided with wearing layer, and the axle central position of axis body is mounting hole, and axis body is provided with some fixed holes, the outer circumferential face of axis body is provided with some grooves, the topside area of groove is larger than bottom area, and the longitudinal section of groove is isosceles-trapezium-shaped, and the cross section of groove is rectangular shape.
Further, between described some fixed holes, arrange rounded shape.
Further, described fixed hole is round-shaped.
Further, described mounting hole is round-shaped.
Further, the quantity of described fixed hole is six.
Further, the quantity of described groove is six.
Adopt the groove type rotating shaft of technique scheme, because the outer surface of described axis body is provided with resin layer, the internal surface of axis body is provided with wearing layer, the axle central position of axis body is mounting hole, axis body is provided with some fixed holes, and the outer circumferential face of axis body is provided with some grooves, and the topside area of groove is larger than bottom area, the longitudinal section of groove is isosceles-trapezium-shaped, and the cross section of groove is rectangular shape; So be used for through metal tube or axle by mounting hole, fixed hole can make axis body be arranged in the rotating shaft of motor etc., can make axis body realize spinfunction, groove on axis body can mate with the projection on another axis body, thereby realize the function of gear, when driving wheel is used, this axis body can be sleeved on axle, easy for installation, good stability.
Accompanying drawing explanation
In order to be illustrated more clearly in the utility model embodiment or technological scheme of the prior art, to the accompanying drawing of required use in embodiment or description of the Prior Art be briefly described below, apparently, accompanying drawing in the following describes is only embodiments more of the present utility model, for those of ordinary skills, do not paying under the prerequisite of creative work, can also obtain according to these accompanying drawings other accompanying drawing.
Fig. 1 is the structural representation of the utility model groove type rotating shaft;
Fig. 2 is the side view of the utility model groove type rotating shaft;
Fig. 3 is A-A sectional drawing in Fig. 2.
Embodiment
Below in conjunction with accompanying drawing, preferred embodiment of the present utility model is described in detail, thereby so that advantage of the present utility model and feature can be easier to be it will be appreciated by those skilled in the art that, protection domain of the present utility model is made to more explicit defining.
As shown in Figure 1 to Figure 3, a kind of groove type rotating shaft, comprise the axis body 1 of being made by stainless steel material, the outer surface of axis body 1 is provided with resin layer, the internal surface of axis body 1 is provided with wearing layer, the axle central position of axis body 1 is mounting hole 2, axis body 1 is provided with some fixed holes 3, the outer circumferential face of axis body 1 is provided with some grooves 4, the topside area of groove 4 is larger than bottom area, the longitudinal section of groove 4 is isosceles-trapezium-shaped, the cross section of groove 4 is rectangular shape, between some fixed holes 3, arrange rounded shape, fixed hole 3 is round-shaped, mounting hole 2 is round-shaped, the quantity of fixed hole 3 is six, the quantity of groove 4 is six.
The rotating shaft of the utility model groove type, by mounting hole 2 for through metal tube or axle, fixed hole 3 can make axis body 1 be arranged in the rotating shaft of motor etc., can make axis body 1 realize spinfunction, the groove 4 on axis body 1 can mate with the projection on another axis body, thereby realizes the function of gear, when driving wheel is used, this axis body 1 can be sleeved on axle, easy for installation, good stability.
The above, be only embodiment of the present utility model, but protection domain of the present utility model is not limited to this, and any variation of expecting without creative work or replacement, within all should being encompassed in protection domain of the present utility model.Therefore, protection domain of the present utility model should be as the criterion with the protection domain that claims were limited.
