Abstract
The invention relates to connection of a mechanical shaft, in particular to a shaft facilitating mounting and fixing of a gear. The shaft comprises a cylindrical main shaft body, and is characterized in that the main shaft body is disconnected in the gear mounting position; end surfaces are perpendicular to an axis of the main shaft body; cross-shaped clamp grooves are symmetrically formed in two end surfaces; cross-shaped clamp blocks are arranged in the clamp grooves and adopt magnetized metal blocks; at least four symmetric key grooves are formed in the circumferential direction of the main shaft body; and the gear is connected and fixed with the main shaft body through the key grooves. The shaft adopting the technical scheme is simple in structure and convenient to process, and facilitates mounting and fixing of the gear.
Description
Technical field
The present invention relates to a kind of connection of mechanical axis, be specifically related to a kind of axle being convenient to installation and fixed gear.
Background technique
The axle of fixed gear refers to supporting gear and pivotal axle therewith, and transmit motion during work, not only bear moment of flexure but also bear moment of torsion, be modal axle in machinery, it is shaft-like that it is generally round metal, and each section also can have different diameters.
Existing gear stationary axle, during owing to installing gear, the shaft shoulder of a bulge loop processed by usual needs in installation position, then a keyway is radially offered at the shaft shoulder, so that gear shaft and gear are fixed together, the material that the processing of the shaft shoulder needs mill off unnecessary, the man-hour of at substantial and material, in addition, when axle is longer, the processing of major axis is not only difficult, and gear to install fixing be also a very large problem.
Summary of the invention
The object of the present invention is to provide a kind of structure simple, be convenient to process and be convenient to install and the axle of fixed gear.
To achieve these goals, the invention provides a kind of axle being convenient to installation and fixed gear, include columniform axle main body, described axle main body disconnects in gear installation place, and described end face, perpendicular to the axis of axle main body, both ends of the surface is symmetrical arranged buckling groove cruciferous, criss-cross clamping block is provided with in described buckling groove, described clamping block is magnetized slug, and the circumference of described axle main body offers at least four symmetrically arranged keyways, and described gear is connected and fixed by keyway and axle main body.
The feature of technique scheme is: because axle main body disconnects in gear installation place, described end face is perpendicular to the axis of axle main body, both ends of the surface are symmetrical arranged buckling groove cruciferous, criss-cross clamping block is provided with in described buckling groove, so can directly gear be placed on the joint of axle main body and not need to penetrate from one end of axle, then with coordinating of buckling groove in both ends of the surface, axle is connected into an entirety by clamping block, circumference due to axle main body offers at least four symmetrically arranged keyways, gear is connected and fixed such axle by keyway and axle main body and gear forms entirety again, gear also plays the join strength of the left and right guarantee axle of garter spring, clamping block is magnetized slug, such installation clamping block can avoid dislocation, install more convenient.
Preferably, in order to ensure the join strength of buckling groove and clamping block itself, ensure that axle can transmit enough large moment of flexure and moment of torsion, the width limiting described buckling groove is not less than 1/6th of axle main diameter, and its degree of depth is not less than the half of width.
Preferably, in order to ensure the join strength between gear and axle main body, reduce the amount of finish of keyway, the length of described keyway is not more than the half of key length simultaneously.
Accompanying drawing explanation
Fig. 1 is the main TV structure schematic diagram of the embodiment of the present invention;
Fig. 2 is the connecting end end view drawing of embodiment of the present invention axis main body.
Embodiment
Below in conjunction with the drawings and specific embodiments, the present invention is further detailed explanation:
As depicted in figs. 1 and 2: the embodiment of the present invention provides a kind of axle being convenient to installation and fixed gear, include columniform axle main body 1, the external diameter of axle main body 1 is unified, do not need to make multidiameter shaft, axle main body 1 disconnects in the installation place of gear 2, the end face disconnected is perpendicular to the central axis of axle main body 1, axle main body 1 both ends of the surface are symmetrical arranged buckling groove 3 cruciferous, buckling groove 3 is directly processed by milling machine, criss-cross clamping block 4 is provided with in buckling groove 3, clamping block 4 and buckling groove 3 interference fit, to position with buckling groove 3 for the ease of clamping block 4 and be connected, clamping block 4 is for adopting magnetized slug, the circumference of axle main body offers at least four symmetrically arranged keyways 5, gear 2 is connected and fixed by keyway 5 and axle main body 1, in order to ensure the join strength of buckling groove 3 and clamping block 4 itself, ensure that axle can transmit enough large moment of flexure and moment of torsion, the width of buckling groove 3 is generally not less than 1/6th of axle main diameter, one-sided buckling groove 3 degree of depth also should not be less than the half of buckling groove 3 width, simultaneously for reducing the amount of finish of keyway 5, the total length of keyway 5 equals key length itself.
When gear 2 is installed, can directly gear 2 be placed on the joint of axle main body 1 and not need to penetrate from one end of axle main body 1, then an overall axle is fitted in by clamping block 4 and the extruding of buckling groove 3 in both ends of the surface, now Fang Jian also should put into keyway 5, together axle main body 1 and gear 2 are formed entirety again, can directly put into keyway 5 because side is strong like this, thus no longer need to process the shaft shoulder, this considerably reduce process time and the waste of material of axle.
Above-described is only the preferred embodiment of the present invention, and in scheme, the general knowledge such as known concrete structure and characteristic does not do too much description at this.Should be understood that; for a person skilled in the art, under the prerequisite not departing from structure of the present invention, some distortion and improvement can also be made; these also should be considered as protection scope of the present invention, and these all can not affect effect of the invention process and practical applicability.
Claims (3)
1. be convenient to the axle of installation and fixed gear, include columniform axle main body, it is characterized in that: described axle main body disconnects in gear installation place, described end face is perpendicular to the axis of axle main body, both ends of the surface are symmetrical arranged buckling groove cruciferous, are provided with criss-cross clamping block in described buckling groove, described clamping block is magnetized slug, the circumference of described axle main body offers at least four symmetrically arranged keyways, and described gear is connected and fixed by keyway and axle main body.
2. the axle being convenient to installation and fixed gear according to claim 1, is characterized in that: the width of described buckling groove is not less than 1/6th of axle main diameter, and its degree of depth is not less than the half of width.
