Description

Technical Field

[0001] The invention relates to the field of flywheel processing equipment, in particular to a flywheel processing equipment. Background Art

[0002] Bicycle self-driving activities are becoming more and more popular. As an indispensable component that provides higher power output, acceleration capability and high-speed movement capability, the cassette flywheel used on bicycles is also increasingly used.

[0003] At the same time, during its use, because its structure includes a flywheel group arranged in a multi-tower shape, there are gaps between the flywheels and the gaps are small. The flywheel teeth of the flywheel are easy to get dirty, with debris and burrs after being used for a period of time, which requires removal for cleaning. Some worn teeth also need to be polished and processed. The flywheel that has been used is different from the flywheel in production. If you want the processed teeth to remain intact and work smoothly, you need to provide a higher polishing speed and polish more smoothly. However, too fast a speed will make it difficult for the coolant to enter the gap of the flywheel, and it is also easy for the high temperature caused by polishing to cause the teeth to deform, affecting subsequent use.
