Abstract
The utility model discloses a duplicate gear which comprises a first connecting shaft (101), a second connecting shaft (102) and a third connecting shaft (103) which are sequentially connected along a coaxial line, and the diameters of the first connecting shaft (101), the second connecting shaft (102) and the third connecting shaft (3) are reduced sequentially, wherein the first connecting shaft (101) is provided with a first tooth part (2); the third connecting shaft (103) is provided with a second tooth part (3); the first connecting shaft (101) is provided with a plurality of lightening holes (4) which axially penetrate through the first connecting shaft (101); the second connecting shaft (102) is provided with a plurality of circular reinforcing ribs (5) which are uniformly distributed at intervals. The duplicate gear disclosed by the utility model has the advantages of material saving, light weight, high strength and difficulty in damage.
Description
Technical field
The utility model relates to a kind of duplicate gear.
Background technique
A kind of duplicate gear is arranged at present, it comprises gear body, gear body is by the first coupling shaft connected successively and diameter reduces successively, the second coupling shaft and the 3rd coupling shaft form, the first coupling shaft is provided with the first tooth section, the 3rd coupling shaft is provided with the second tooth section, the first coupling shaft is provided with several and axially connects the lightening hole of the first coupling shaft, lightening hole can make this duplicate gear save material, and make the weight reducing of this duplicate gear, while making this duplicate gear work, kinetic equation loss reduces, but this duplicate gear is owing to being provided with lightening hole, make its intensity lower, than being easier to, damage.
The model utility content
Technical problem to be solved in the utility model is, provide and both save material, weight is less, again intensity higher, do not allow flimsy duplicate gear.
For solving the problems of the technologies described above, the duplicate gear that the utility model provides, it comprises the first coupling shaft, the second coupling shaft and the 3rd coupling shaft that coaxial line connects and diameter reduces successively successively, the first coupling shaft is provided with the first tooth section, the 3rd coupling shaft is provided with the second tooth section, the first coupling shaft is provided with several and axially connects the lightening hole of the first coupling shaft, and described the second coupling shaft is provided with some the equally distributed circular stiffening ribs in interval.
After adopting above structure, the utility model compared with prior art, has advantages of following:
Lightening hole makes this duplicate gear save material, weight is less, and working room's kinetic equation loss is less, and, owing to being provided with circular stiffening rib, makes this duplicate gear strength increase, when this duplicate gear is used, is not easy to damage.
As preferably, the number of teeth that the number of teeth of described the first tooth section is 6, the second tooth sections is 16.
