Abstract
A kind of internal connecting type rotating shaft, relate to rotatable parts technical field, what solve is the technical problem increased the service life.The axis body of this rotating shaft at least at one end end opens has the stomidium with inner conical surface, and is built-in with movable cone block at stomidium; Described stomidium and cone block cone match, the axis of stomidium and cone block all with the dead in line of axis body, and the little head end of cone block is towards the aperture of stomidium, and the axle center of boring block offers axial through screw.The rotating shaft that the utility model provides, is suitable as the rotating shaft use of belt pulley, gear.
Description
Technical field
The utility model relates to rotatable parts technology, particularly relates to a kind of technology of internal connecting type rotating shaft.
Background technique
The mechanical part such as belt pulley, gear is all assemblied in rotating shaft and uses, traditional rotating shaft is all provided with draw-in groove in end, card key is processed with in the axis hole of the wheel body such as belt pulley, gear, the wheel body such as belt pulley, gear coordinates by card key and draw-in groove the end being assemblied in rotating shaft, the defect of this assembling mode is: roller end is main bearing position (position be combined with wheel body) just, but owing to needing to arrange draw-in groove in the end of rotating shaft, therefore roller end relatively thin (outer end diameter diminishes), also easily damage accordingly, working life is shorter.
Model utility content
For the defect existed in above-mentioned prior art, technical problem to be solved in the utility model is to provide a kind of internal connecting type rotating shaft of long service life.
In order to solve the problems of the technologies described above, a kind of internal connecting type rotating shaft provided by the utility model, comprises axis body, it is characterized in that: described axis body at least at one end end opens has the stomidium with inner conical surface, and is built-in with movable cone block at stomidium;
Described stomidium and cone block cone match, the axis of stomidium and cone block all with the dead in line of axis body, and the little head end of cone block is towards the aperture of stomidium, and the axle center of boring block offers axial through screw.
The internal connecting type rotating shaft that the utility model provides, wheel body is fixed on axis body end by bolt and cone block, stomidium is then fixed by the frictional fit of the conical surface with cone block, thus change the combination of wheel body and rotating shaft into axial combination from traditional radial combination, adopt this axial combination rotating shaft overall processing can be become thickness consistent, the working life of rotating shaft can be extended.
Accompanying drawing explanation
Fig. 1, Fig. 2 are the schematic diagram of internal connecting type rotating shaft at end assembling belt pulley of the utility model embodiment, and Fig. 1 is wherein the schematic diagram before assembling, and Fig. 2 is the schematic diagram after assembling.
Embodiment
Illustrate below in conjunction with accompanying drawing and be described in further detail embodiment of the present utility model, but the present embodiment is not limited to the utility model, every employing analog structure of the present utility model and similar change thereof, all should list protection domain of the present utility model in.
As Figure 1-Figure 2, a kind of internal connecting type rotating shaft that the utility model embodiment provides, comprises axis body 1, it is characterized in that: described axis body 1 at least at one end end opens has the stomidium 2 with inner conical surface 5, and is built-in with movable cone block 3 at stomidium 2;
Described stomidium 2 and cone block 3 cone match, the axis of stomidium 2 and cone block 3 all with the dead in line of axis body 1, and the little head end of cone block 3 is towards the aperture of stomidium 2, and the axle center of boring block 3 offers axial through screw 4.
The utility model embodiment is particularly suitable as belt pulley, the rotating shaft of gear uses, for belt pulley, during assembling, stretch in the stomidium 2 of axis body 1 end after first the screw rod of a bolt 6 being passed the axis hole of belt pulley 7, again the screw rod of bolt 6 is screwed into the screw 4 in cone block 3 axle center, belt pulley 7 coaxially can be fixed on the end of axis body 1 after tightening by bolt 6 and cone block 3.
