Above-mentioned scheme improves the subproblem of prior art to a certain extent, but the program also at least exists following defect: design unreasonable, still there is structural strength difference, the manufacture cycle long and technical problem that cost is high.
Model utility content
The purpose of this utility model is for the problems referred to above, and provide a kind of design more reasonable, structural strength is high, and performance is good, the output shaft that with short production cycle and cost of production is low.
For achieving the above object, the utility model have employed following technical proposal: this output shaft comprises output shaft body, described input shaft body is provided with lip part, described input shaft body side is input end, described input shaft body opposite side is provided with gear, and described output shaft body, input end, gear are made up of metallic material and output shaft body, input end, gear are integral type structure.
In above-mentioned output shaft, described output shaft is made by the one-body molded mode of cold hobbing.
In above-mentioned output shaft, described gear comprises multiple tooth distributed radially, is provided with teeth groove between adjacent tooth, and described teeth groove is the cambered surface concentric with gear.
In above-mentioned output shaft, the tip diameter of described gear is 3:2 with root diameter ratio.
In above-mentioned output shaft, the pressure angle of described gear is no more than 15 °.
In above-mentioned output shaft, described gear is connected by the first chamfered transition with input shaft body, and the angle of the first described inclined-plane and input shaft body shaft axis is 45 °.
In above-mentioned output shaft, described input end is provided with keyway, and described input end diameter and input shaft body diameter are than being 1:1.2.
In above-mentioned output shaft, described input end is connected by the second chamfered transition with output shaft body, and the angle of the second inclined-plane and input shaft body shaft axis is 30 °.
Compared with prior art, the advantage of this output shaft is: 1, design is more reasonable, and structural strength is high, and performance is good.2, with short production cycle, spillage of material is little, and cost of production is low.
