Embodiment 1
[0023] Example 1 see figure 1 , figure 2 , image 3 , Figure 4 A method for regenerating motorcycle sprockets is used for galvanized or painted waste sprockets, comprising the following steps:
[0024] The first step, waste sprocket recovery: selectively recycle waste motorcycle sprockets with no cracks in the sprocket body. Shaped weight-reducing holes and 4 one-way screw connection holes 2;
[0025] The second step, annealing treatment: tempering the waste sprocket;
[0026] The third step, cutting process: use a lathe to cut off the sprockets of the waste sprocket by cutting, forming the addendum circle of the regenerated sprocket 3 and the chamfers on both sides of the regenerated sprocket 3; and positioning the one-way clutch of the waste sprocket The hole expands 1.0mm in the diameter direction coaxially;
[0027] The fourth step, rolling sprocket: the regenerated sprocket 3 is formed by hobbing with a gear hobbing machine, and the number of teeth of the regenera...
Embodiment 2
[0031] Example 2, see figure 1 , figure 2 , image 3 , Figure 4 , a motorcycle sprocket regeneration method for waste sprockets with an injection-molded protective layer, comprising the following steps:
[0032] The first step, waste sprocket recycling: selectively recycle waste motorcycle sprockets with no cracks in the sprocket body. Weight reduction holes and 4 one-way clutch screw connection holes 2;
[0033] The second step, recycling of injection molding materials: heat the waste sprockets to melt the injection molding materials and separate them from the body of the waste sprockets and recycle the injection molding materials;
[0034] The third step, annealing treatment: tempering the waste sprocket;
[0035] The fourth step, cutting process: use a lathe to cut off the sprockets of the waste sprocket by cutting to form the addendum circle of the regenerated sprocket 3 and the chamfers on both sides of the regenerated sprocket 3;
[0036] Step 5, rolling sprocket...
