Embodiment 1

As shown in figures 2-6, a kind of wind-driven generator reduction box that the present embodiment is provided, it includes that casing 1, power are defeated Shaft 5, output gear 4, input gear 3 and motor 7；

Output gear 4 is arranged on power output shaft 5, and is rotatably arranged in casing 1 by power output shaft 5；

Input gear 3 is rotatably arranged in casing 1；

Several input gears 3 are circumferentially disposed along output gear 4, and input gear 3 is meshed with output gear 4, motor 7 with Input gear 3 connects, and drives output gear 4 to rotate by several input gears 3.

This utility model simple in construction, the radius of output gear 4 be more than input gear 3 radius, the radius of output gear 4 with The ratio of input gear 3 radius is in the case of meeting total reduction ratio requirement, and this utility model self structure only needs one-level tooth Wheel transmission, thus greatly reduces manufacture and assembly difficulty, and manufacturing cost is lower, safeguards the most convenient.

In contrast, in prior art, planetary gear deceleration box generally planetary gears adds parallel-axes gears structure, Structure is complicated, and manufacture, assembly precision require height, thus while cost height, it is also difficult to practice and extension.

Input gear 3 of the present utility model is rotatably arranged on casing 1 by rotating shaft 3a, wherein, input gear 3 with Rotating shaft 3a is preferably integral structure, i.e. input gear 3 is the gear shaft being rotatably provided on casing 1.

Certainly, input gear 3 and rotating shaft 3a can also be split-type structural, the most respectively processing input gear 3 and rotating shaft 3a, Both are fitted together by the form such as spline and spline, form power input structure.

Wherein, several input gears 3 are evenly arranged along output gear 4 circumference.When input gear 3 is uniformly distributed, horse When reaching 7 work, multiple input gears 3 make a concerted effort to be zero, thus, work for radial effect produced by output gear 4 and casing 1 When making, the destructive power for output gear 4 and casing 1 is less, and during motion, produced vibration and noise are less simultaneously.

And the left and right two ends of input gear 3 are connected with two motors 7 respectively, two motors 7 drive from two ends, left and right simultaneously One input gear 3 rotates.

Owing to this utility model uses one-level speed changing structure, commonly enter the gear ratio between gear 3 and output gear 4 relatively Greatly, synchronize to drive input gear 3 to rotate by arranging motor 7 in the lateral symmetry of casing 1, the power of this utility model reduction box Performance is higher.

Certainly the gear ratio between input gear 3 and output gear 4 is little, and casing 1 also can arrange motor 7, i.e. in one side The technical scheme being driven an input gear 3 i.e. can meet application by single-motor 7 also should be included in guarantor of the present utility model Within the scope of protecting.
