Specific embodiment
The utility model is described in further detail in the following with reference to the drawings and specific embodiments, so that those skilled in the art
The utility model may be better understood and can be practiced, but illustrated embodiment is not as the restriction to the utility model.
As Figure 1-Figure 2, a kind of gear shaft of spur gear, including the first cylindrical portion 1, the periphery of the first cylindrical portion 1
On be provided with keyway 13, the both ends of the surface of the first cylindrical portion 1 are respectively first end face 11 and second end face 12, first end face 11 and
It is respectively connected with the second cylindrical portion 2 on biend 12, is provided with section 21 in the second cylindrical portion 2, positioned at 11 side of first end face
The section 21 of second cylindrical portion 2 and the section 21 of the second cylindrical portion 2 positioned at 12 side of second end face are perpendicular, the setting of section 21
So that there are gaps between the part of the second cylindrical portion 2 and socket on it, convenient for heat dissipation, while using in the second cylindrical portion 2
Upper direct cut-out arc surface and the form for constituting section 21 are also more conducive to guarantee the second cylindrical portion 2 and socket on it
Stable connection degree between part, two sections 21 are perpendicular, are on the one hand more conducive to the circumferentially positioned of gear shaft, prevent its generation
It slips, is on the other hand also more conducive to improve the heat dissipation effect of gear shaft entirety, while also can guarantee the smooth running degree of gear shaft.
Wherein, the first cylindrical portion 1 is for connecting spur gear.
Wherein, it is also pasted on the periphery of the first cylindrical portion 1 wearing layer (being not shown in Fig. 1 and Fig. 2), is set on wearing layer
Multiple circular holes are equipped with, certain heat dissipation effect is also functioned to while to enhance wearability.
Further, section 21 without the axis of the second cylindrical portion 2 namely section 21 always not with the second cylindrical portion 2
Axial section coincide, this can enable the areas that the area of section 21 is consistently less than above-mentioned axial section, to better ensure that
Stable connection between the part of second cylindrical portion 2 and socket on it.
In a wherein embodiment, it is provided on the periphery of the first cylindrical portion 1 multiple in positioning circumferentially
Convex block 14, to play positioning action to spur gear, which realizes positioning using multiple locating convex blocks 14, enables to straight
Gear is more uniformly stressed, and is also conducive to the positioning stable degree of enhancing spur gear；Location structure is simple, convenient for arranging and saving material
Material.
Further, locating convex block 14 is in and is arranged circumferentially on the periphery of the first cylindrical portion 1, so that when positioning
It exerts a force more uniform.
Further, locating convex block 14 is sectorial block, and locating effect is more preferable.
Further, location hole 23 and multiple oilholes 24 are provided on an end face (outer end face) of the second cylindrical portion 2.It is fixed
Position hole 23 is conducive to the positioning in the center of circle of gear shaft, and oilhole 24 is for storing lubricating oil and playing lubricating action to shaft end portion.
Further, the diameter of oilhole 24 is greater than the diameter of location hole 23, and the diameter of location hole 23 should not be too large.
