Problems solved by technology

This method has a cumbersome process route and low regeneration efficiency. It is only suitable for repairing and regenerating single-piece sprockets of large-scale construction machinery or mining machinery. It is obviously not suitable for a large number of motorcycle sprockets.

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...

Abstract

The invention discloses a motorcycle sprocket regeneration method. The method comprises waste sprocket recovery: motorcycle waste sprockets flawless in sprocket bodies are recovered selectively, and lightening holes and screw connection holes are formed in the sprocket bodies; annealing treatment: the waste sprockets are subjected to annealing treatment; cutting machining: teeth of the waste sprockets are removed through a turning mode to form addendum circles of regenerated sprockets; rolling the teeth: the regenerated teeth are subjected to roll cutting, and the number of the teeth of the regenerated sprockets are 2 to 4 smaller than that of the teeth of the waste sprockets; quenching and tempering: local quenching and tempering is performed on the teeth of the regenerated sprockets; injection molding: injection molding layers are formed on the sprocket bodies of the regenerated sprockets by using modified polypropylene for vehicles through an injection molding mode to form regenerated sprocket finished products, and the injection portions on the two sides of the sprocket bodies are integrated through portions covering the lightening holes and the screw connection holes. The method has the advantages that waste sprocket resources are fully used, the regeneration efficiency is high, regeneration costs are low, and economic benefits and social benefits are apparent.

Description

technical field [0001] The invention relates to a sprocket recovery and utilization, in particular to a motorcycle sprocket regeneration method. Background technique [0002] Motorcycle is a common means of transportation throughout urban and rural areas. The power transmission of motorcycles mainly adopts chain transmission. The large sprocket or chain disc rotates, and the large sprocket is connected with the driving hub of the motorcycle through a one-way clutch, thereby realizing the power transmission of the motorcycle. For the protection of the chain part of the sprocket wheel of an ordinary motorcycle, a protective cover is provided outside the chain teeth of the chain and the sprocket wheel only for safety considerations, which belongs to an open transmission system. Most of the body of the large sprocket is exposed. In order to ensure the service life and appearance quality of the large sprocket body, it is usually necessary to carry out surface protection treatmen...
